5 cl, 2 dwg

This invention relates to the release of fluid in accordance with the distinctive part of the clause 1 of the claims.

WO 2007/009617 A1 opens the attachment for the release of fluid from the exhaust tip, with outlet and includes the inner sleeve. In the inner sleeve is an internal body that defines the boundaries of the output of a canal site and has a connecting element to ensure accession to the joined detail outlet. At the end, adjacent to the outlet, inner liner has the sealing surface against which the cone placed on the internal housing and closing the output section of the channel, is in pre-tensioned. Therefore, the valve is integrated in the exhaust nozzle, in which the shutter valve is carried out by the relative motion when triggered by the user. With this aim, head for the release of fluid and outlet can be displaced axially toward each other. When working force is released, the components are returned to the initial position in the opposite direction through the spring. In addition provides a means of preventing the recovery to ensure that the insert for the release of fluid and outlet are not separated from each other in the direction opposite direction.

With this purpose, a tool to prevent pulling have a circle edge and nest for her at the graduation of the nozzle tip to release the fluid. The disadvantage is that the way to prevent pulling posted by fully inside the body of the insert for the release of fluid. Body has a cap that much is issued and that reduces the possibility of manipulating the spray, built from the insert for the release of fluid and outlet.

Therefore, the aim of the invention is development of a nozzle to release the fluid, which gives a better opportunity manipulation.

This goal is achieved due to the properties item 1 of the claims.

Thus, it is proposed nozzle for the release of fluid in which additional, second skirt improves the management of the insert to release the fluid on the final device, in particular, in combination with a fixing with a protective device. A tool to prevent recovery, therefore, a built-in guide, which orients the axial movement of the nozzle to the release of fluid and exhaust devices relative to each other during actuation of the atomizer, the linking of them.

On further improvements of this invention can conclude from the following description and dependent claims.

This invention will be described in more detail below using the sample implementation options, enclosed drawings.

Figure 1 schematically in the context presents insert for the release of fluid with a plot outlet;

figure 2 are the two components, according to figure 1, disassembled.

This invention relates to attachment 1 for the release of fluid with a venting device 2 and outlet 2 contains the drive substances (not shown) for fluid flow in which liquid substance is placed under pressure, or from which the liquid substance produced by the pump 3, in particular the pressure piston pump. Outlet 2 preferably has item 4, which can be attached to attachment 1 to release the fluid.

Outlet 2 and attachment 1 to release the fluid, assembled, constitute the nebulizer for specific liquid media.

Attachment 1 for the release of fluid and outlet 2 can be displaced axially toward each other with the objective of enhancing the release of fluid shortening the atomizer. When working force is released, they return in the opposite direction in the initial position, according to figure 1, by means of spring F.

Attachment 1 to release the fluid has exhaust tip 5, which can be placed on prom device 2 and which includes a guide item 8 for substances in the form of a channel for substances and outlet for substances having outlet 6 at the end of the guide part 8 for substances. In the area of the exhaust pipe of a substance is provided a removable sealing element 10, which can move the position to the open position and who, preferably, formed as the body of the pre-stressed valve.

Exhaust tip 5 has skirt 9 to create a moving guiding element with a plot of 11 at the prom device 2. With this skirt 9 exhaust tip 5 linked with the second, additional skirt 12 for the formation of a ring-shaped sleeve 13. Ring sleeve 13 can be mounted in such a way that it can move in the longitudinal axial direction on the part 11 outlet 2, which is formed as an annular core. Second, additional skirt 12, preferably, is to be radially springy. With this purpose, second, additional skirt 12 may be shorter in length than the other skirt 9. Second, additional skirt 12 preferably formed to be shorter so that between the two skirts 9, 12 is formed radial snap sloping ground.

Second, additional skirt 12 preferably is the outer skirt 12, while the other skirt 9 represents the inner skirt 9. Edge 14 preferably stands inside a ring-shaped sleeve 13, forming a tool to prevent pulling out. Edge 14 preferably intended as a side internal skirts 9. edge of 15 opposite edges 14 is formed on a site 11.

Next, preferably at the tip 5 was provided push part 16, which has a surface of 17 capture. Then the second, additional skirt preferably 12 is formed on the part of the push 16. Push part of 16 can be made from a material which differs from material exhaust tip 5. Thus, there is a possibility of manufacturing two skirts 9, 12 of different materials. In particular, the second, additional skirt 12 may consist of more soft plastic than the other skirt 9.

Exhaust tip 5 ignitable inner sleeve 18, which defines the boundaries of the guide part 8 for substances attached to the exhaust section 19 a guide 20 for substances in the form of sections channel and/or cavities for substances that are adjacent to each other and placed within the nozzle 1 to release the fluid.

At the end, turned to the outlet 6, inner sleeve 18 is shaped like a bowl. To close the outlet 6, inner sleeve 18 contains a body 10 spring loaded valve is automatically closing the outlet 6 with this end.

Building 10 valve formed as a cylinder piston, which closes the outlet 6 as housing 10 spring loaded valve through the efforts of preliminary tension spring 21. Building 10 valve has an intermediate plate 25 valve, which hermetically isolates camera 22 pressure connected with the guide part 8 for substances through the top of the valve seat insert 23 block 10 of the valve. Intermediate plate 25 valve preferably used additionally for the direction of movement of body 10 valve.

To open the upper valve saddle 23, in the chamber 22 pressure can be set discharge pressure of the substance, which is higher than the spring force 21 compression, which keeps the building 10 valve closed. Figure 1 shows the outlet 6, closed housing 10 valve.

Substance flows through the body 10 valve, which in the housing 10 valve has a lock canal 24, which connects the guide item 8 for substances with a camera 22 pressure.

Exhaust tip 5, in this case, has the form of a nasal applicator, that it was possible to put the joined detail 4 as a nasal transitional devices. For other versions of the application of exhaust tip 5 may have other contours of the outer surface.
