2420-184933RU/035 DEVICE FOR FLUID SUPPLY Description The invention relates to the field of fluid supply, in particular in the form of drops in the pharmaceutical field, for example, eye or ear fluids. The known device for liquid supply, equipped with a tank and switch tip, located on the tank, and this cap is provided with a caliper and the closing element. For example, in the document US 2007/0210115 distribution tip contains the caliper, inside of which is placed a closing element that is moved between the locked position and the position of the transmission fluid. This closing element contains, in addition, at its far end near the hole for the passage of fluid to the device to reduce the flow of fluid. This device is to reduce the flow contains the channel spiral shape of small cross section, allowing to reject the liquid in order to cause a pressure loss, when the user clicks on the tank. Thanks to this device, to reduce consumption, eliminate the flow of liquid in the form of a spray. During the development of the invention the applicant has found that the difficulty lies in the fact that the device for reducing fluid flow is performed in the same part as the device providing the blocking or deletion of the LM the bone. Indeed, this configuration requires that the valve and the caliper had a very precise dimensions, so as to simultaneously move the valve relative to the caliper to ensure the transmission fluid and sufficiently close interaction between form for deviations and caliper to obtain channel rejection, no leaks, in consequence of which would be designated waste reduction. Thus, it is difficult to perform items that require such precision sizes. The present invention is to develop a device for feeding, ensure the reduction of the flow rate and guarantee the satisfactory operation when applying a liquid. To solve this problem is proposed, in particular, a device for feeding a liquid containing: a reservoir for storage of liquid transferred, with tip mounted on the tank, equipped with a caliper and a valve for distributing fluid, and this valve may take the position block and the position of the transmission fluid by interaction with the caliper, - the body reduce the flow that contains the form to reject fluid restricting the channel to reduce consumption, and this body reducing consumption is a part that is separate from the caliper and the individual on the valve. The function of decreasing the amount expected to be carried out by a third part that is separate from the valve and caliper, that is detachable from the valve and caliper, or at least separated from the other two before assembling. Introducing a separate item to ensure restriction of fluid flow, parts of the handpiece, which ensure the integrity of the device by blocking or transmission fluid, and the parts which carry out waste reduction. Indeed, the reduction of consumption is the third item that is not located in the immediate vicinity of the sealing part is made between the valve and the caliper, the function of tightness can be ensured regardless of whether the reduction of consumption, hence, each function is performed easily and optimally. Although one would expect that the Assembly of the device will be more complex due to the addition of a new part, Assembly is simple, as the area reduction of consumption no longer depends on the shape of the valve and the caliper, ensuring the tightness of the unit. Therefore, it is easier to change the length and diameter of this device to reduce consumption. In addition, since the reduction of consumption is no longer done in the area of the sealing tip, the latter may have a smaller length and allows the t, thus, to perform the tips more compact. Because the functions are separated, the manufacture is facilitated due to the fact that changing the dimensions of the parts less impact on the operation of the device. This is an advantage, because at high accuracy requirements, the production becomes more difficult due to the fragility of tools or damage to the moulds. In addition, a special advantage is that it becomes possible to easily adapt the reporting device to the type of the distributed fluid. Indeed, depending on the viscosity of the liquid channel to reduce consumption is to have a special configuration. For example, you can provide a channel of decreasing flow rate with a larger diameter for very viscous liquids. Thus, as the body reducing consumption is a separate item, in order to adapt the distribution tip to the type of the distributed fluid enough to change only the shape of the body to reduce consumption without changing the shape of the valve or caliper, which can, thus, to have a standard form. In addition, since the reduction of the flow is provided by a separate piece, you can have a device that performs the function of reducing consumption, and the device does not perform such a function, if this is have a unique difference between these devices will be in the presence or absence of a body to reduce consumption. It should be noted that especially important is the adaptation of the device to the viscosity of the product due to the fact that products such as ophthalmic products tend to become more and more viscous, in particular, products, preservative agent. The phrase "waste reduction" means the reduction in the rate of leakage of fluid at the same pressure exerted by the user on the tank. This reduction of the flow rate preferably is channel having a smaller cross-section than the other selects the channels provided in the device, and/or passing along a great length, and/or having transverse axis. Preferably, the filling device could benefit from organ to reduce consumption and to limit, therefore, the dead volume, which in switch tip, as the void volume is a source of bacteria. Device for fluid supply may also have one or more differences. - Stupor contains a seat for the reception of the body to reduce consumption, limiting together with the last channel to reduce consumption. This seat can be, for example, is located opposite the supporting part, which ensures the sealing device so that even more limited is ICICI interaction between the flow restriction and tightness. Preferably, it is the receiving seat has an essentially cylindrical shape, bounding the cavity volume, essentially, additional to the volume of the body to reduce consumption. - Body slimming consumption has essentially a cylindrical shape, and the shape of deviation in the direction performed on the outer periphery of the body to reduce consumption and contains a spiral groove. This spiral shape of the channel informs the transverse flow direction that is not parallel to the direction of the flow, giving the channel a relatively large length, which allows to obtain the pressure loss, occupying minimal space in the device. - Body slimming consumption has essentially a cylindrical shape, and the shape of deviation in the direction made by the external periphery of the body to reduce consumption and has a groove made with angular cuts. These corner pieces allow you to get the trajectory with pronounced changes in the direction that violates the fluid flow and causes a great loss of pressure. - Body slimming consumption has essentially a cylindrical shape, and the shape of deviation in the direction made by the external periphery of the body to reduce consumption and contains a rectangular groove, preferably essentially parallel to the axis of the cylinder body to reduce pressure. Because of the geometrical the ski characteristics grooves, in particular, the dimensions of its cross section, the fluid flow is disturbed and causes a pressure loss, which may be sufficient to reduce the flow. - Body slimming consumption has essentially a cylindrical shape, the shape of the deviations made by the external periphery of the body to reduce consumption and maintains a network of multiple grooves, containing at least one node of convergence. This creates an area of violation and causes an increased pressure loss. The caliper includes a sealing part having the surface of the valve for blocking passage of fluid, while the sealing part has an essentially cylindrical shape, and a surface located at the distal end of this cylindrical shape. This sealing part has essentially the form of a rod overlying the slot in the respective sealed valve parts. - The valve contains, essentially, a cylindrical portion that overlaps an additional cylindrical support, and bounding with support channel transmission fluid, performed at the output of the channel to reduce consumption. - The valve contains a part of the permanent mounting of the valve on the caliper, and the part having essentially the form of a disk, which is a cylindrical part. The valve includes an elastomeric material, and the while having a rigid part, for example, which serves as a support for the return spring moves the valve to a position blocking fluid. The caliper contains, in addition, a channel for the passage of air into the tank, provided with a hydrophobic filter. It can be stated that the caliper can perform some functions in the tip, namely, the sealing function, the function of reducing fluid, the function of fastening the valve and/or the transmission function of air for purging the tank. The invention also has for an object the construction of the two devices described above, and each of the two devices has a valve, the caliper of the same shape and the body reduce the consumption of various forms. For example, the channel reduction of consumption may have a different cross-section, of a different length or a different shape. The invention is further explained in the following description, which is not restrictive, with reference to the accompanying drawings, in which: Figure 1 depicts a view in longitudinal section of the device allocation in accordance with a variant embodiment; Figure 2 depicts a view in partial longitudinal section of the device allocation in accordance with a second variant embodiment; and Figa-3f depict side views of the body to reduce consumption in accordance with various options. Figure 1 shows Nakonechny is 10 for the fluid in the form of droplets, designed for installation screw on the neck of the tank 12, shown by dashed line. The tank 12 is a reservoir for storage of such pharmaceutical liquids, like eye or ear fluid. Fluid flow is accomplished by pressure by the user on the body of the tank 12, the latter has a certain elasticity to restore its original shape after pressure by the user. Distribution handpiece 10 includes, in this example, the support plate 14, the control valve 16, the spring 17, the cap 18, the body 20 of the reduction of consumption and the hydrophobic filter 22. The valve 16, the support plate 14 and the body 20 of the reduce form of individual parts that just fit each other and separated before installation. The caliper 14 contains in this example, item 24 attachment on the tank, located in the immediate vicinity of the caliper 14. This item contains 24 of the outer skirt 26 with a screw thread to nevinovate on the neck of the tank 12. Item mount 24 includes, in addition, the inner skirt 28 of the tubular form in order to ensure tightness between the tank 12 and the switch tip 10. The support 14 also includes a seat 30 for receiving the body reduce consumption 20 located essentially in cylindri eskay cavity, moreover, this cavity is opened at its near end to the tank 12, and at its distal end into the first channel 32 for transmission fluid made in the caliper 14 and placed in the longitudinal direction of the device, corresponding, in this case, the direction of the flow shown by the arrow 33. This first channel 32 opens into the intermediate cavity 34, which itself opens into the second channel 36 for transmission fluid. The caliper 14 contains, in addition, the Central sealing part 38, essentially cylindrical shape, located in the distal direction, opposite the inner skirt 28. Part 38 at its distal end has a surface 40 of a support of the valve 16 to block the transmittance of the liquid in the closed position. In this example, the support surface 40 has the form of an annular collar. The caliper 14 in this example also includes a channel 42 for the passage of air into the tank 12, the opening in the seat 44, which is hydrophobic filter 22. The seat 44 is located next to the mounting seat 30 for receiving body 20 to reduce consumption, being separated by a Central wall 46 which extends in a direction opposite to the sealing part 38. Finally, the support plate 14 contains the locking portion 48 of the valve 16 on the caliper u This part 48 performs the function of fixing parts of the skin the ha 18 on the support 14. It contains an annular groove 50, limited by the periphery of the annular wall 52. Annular groove 50 is limited, in addition, on the inner periphery of the annular rib made on the inner wall, forming, in essence, the disc crossed the channel 32, and bounding the cavity 34. The valve 16 may take the configuration block and configuration of the transmission fluid by interaction with the caliper 14. In this example, it is made of elastomeric material. In another example, only a portion of the valve 16 is made of an elastomeric material, and the other part is made of a rigid material, it may serve as a support for the springs 17. The valve 16 includes a portion 54 of the attachment to the support plate 14, forming, in essence, the skirt of the tubular form. This part of the mount 54 is connected with a thin partition wall 56 having essentially the form of a disk and which is, essentially, a cylindrical part 58. Thin wall 56 also includes a support seat 57 for accommodating the spring 17. Part 58 forms an internal cavity, essentially cylindrical shape, additional to the terminal 38. The rod 38 and the cylindrical portion 58 are coaxial and together form a channel 36 for passage. This channel 36 for passage opens into the outlet channel 60, is made in the distal end of the valve 16, which itself becomes a form 62 formed for the I drops. The casing 18 includes a portion 64 for mounting on the annular support plate 14, and the other annular part 66, coaxial with the part 64 so as to form a groove 68 which abuts the annular wall 52. The casing 18 includes, in addition, the seat 70 to the spring seat 17, continued along the inner periphery of the annular wall 72, the intersecting part 58 and perform the function of centering portion 58 of the valve 16. The body 20 of the reduction of the consumption is of the form 74 to discard the liquid, forming with a mounting seat 30 channel 76 to reduce consumption. The body 20 to reduce consumption 20 may be made in the form of one of the forms depicted in FIGU-3f. It has essentially a cylindrical shape, and the shape of 74 deviations made on its outer periphery, forming a peripheral cavity. In the examples on figa, 3b form 74 is made in the form of helical grooves a, 74b, which makes the rotation of the cylinder 20, and, preferably, a few turns, if the liquid has a low viscosity. Groove a has a greater cross-section than the groove 74b, and is intended for liquids with a higher viscosity than the groove 74b. The bodies 20 pigs and 3d depict other types of grooves s, 74d, which do not turn around the cylindrical part 20 and which is formed corner pieces, in this case rectangular, intended for the mind is isenia pressure fluid liquid. If necessary, the body 20 can include on other parts of their peripheral walls of the grooves, like grooves s, 74d to increase fluid consumption. The body 20 on five contains rectilinear groove 74A, essentially parallel to the axis of the cylindrical part. Alternatively, the body 20 includes multiple grooves 74A, distributed over the surface of the peripheral wall of the body 20. In another embodiment, one or more grooves 74A executed inclined relative to the axis of the cylinder. The body 20 on fig.3f contains a network of grooves 74f-h, including site 74i connection grooves 74f-h. The network contains grooves 74f-g, called the input, located at the input node 74i and at least one groove 74h, called output, located at the exit node 74i. Alternatively, the network may contain more than two output grooves 74f-g, more than one output grooves 74h and more than one node 74i. The operation of the device of figure 1 will be presented below. In the rest state, i.e. when the user clicks on the tank 12, the valve 16 is in the configuration of the blocking fluid, that is, it rests on the surface 40 due to its permanent mounting on a support plate 14 carrying a resilient pressure on the valve, under the action of pressure being exerted by the spring 17. When the user presses the tank 12, it carries out the pressure W is dcost, which comes in the only channel that provides its flow (hydrophobic filter 22 prevents fluid flow), namely, in the channel 76 to reduce consumption. In the process of its receipt in the channel 76, the fluid flow is reduced due to loss of pressure. The liquid flows further into the channel 32, and then into the cavity 34 and channel 36. Under the action of pressure fluid raises the membrane 16, which passes next to the position of the transmission fluid, and can thus take place between the membrane 16 and the support surface 40 for passage in the channel 60 and into the cavity 61, and, thus, be formed in the form of a drop. It should be noted that the body 20 of the reduction of consumption, is a single item, which may have the form variable depending on the liquid contained in the tank. Thus, the seat 30 can take the body 20 different forms, such as are depicted in FIGU-3f. Thus, it is possible to make the batches of nozzles having the same valve 16, the same caliper 14, the same casing 18, but different bodies 20. Tip 10 may have a configuration different from the configurations shown in figure 1, such as shown in figure 2. The tip 2 has functions similar to the functions of the tip of figure 1, except that it does not contain a channel 42 for the festival of the and air. In this variant embodiment, the reservoir 12, preferably, is not elastic deformable reservoir, because there is no need to supply air to compensate for the pressure reduction caused by the user when the pressure on the tank. Thus, in this example, the seat 30 is located in the center of the support plate 14 and the body 20 of the pressure reduction may be larger in diameter.
