The invention relates to sanitary-technical equipment and can be used in water supply systems, in particular in the taps faucets.

Known discharge device used in the mixer containing the tank with saddle and outlet is located inside of the tank dosing uskh between a flexible shaft (EN, 2005140 C1, E 03 C 1/04, 30.12.93).

The main disadvantage of this device is unstable due to the lack of trenirovki air, unspecified orientation relative to the valve seat and the increase in size of the crane.

The closest in technical essence and the achieved effect is known mixer taps, in which the discharge device made in the form of a tank with the saddle and the outlet opening and closing of the outlet device made in the form of a spherical valve positive buoyancy and siphon tube with a drainage hole at the top of the bend, while the discharge end of the siphon tube is connected with the channel in the body of the tank communicating with the outlet below the valve (EN, 2005139 C1, E 03 C 1/04, 30.12.93).

The main disadvantage of this faucet-mixer is a limited possibility of trenirovki air associated with the fact that trenirovka is inward flow is drained of water, which hinders the free (instantaneous) discharge accumulated in the water tank, and an automatic drain in the inappropriate time, design complexity, the inability to use one-to-one existing mixers of various designs.

The technical solution of this problem is that the mixer contains a tank with saddle and outlet placed inside the tank spherical valve with positive buoyancy, the drainage system of the tank and drain tube with a horizontal part, and the tank placed the console on the end of the horizontal portion of the drain tube, and a drainage system made in the form of isolated cavities, informing the inner upper part of the tank with the space atmosphere, located outside of the flow of water in the area of its discharge from the tank.

When this valve is equipped with speakers for the outlet tip with total valve positive buoyancy, in addition, the valve is provided with a drain tube located coaxially with the tip, the tip and the valve is made a through hole in communication with the drainage tube, with the tip valve and drain pipe summarily executed with positive buoyancy, and the tank is equipped with a guide for the drainage tube in the blank hollow ledge.

In Fig. 1 and 2 shows a General view of mixers respectively for baths and kitchens equipped with a tank at the end of the drain tubes.

In Fig. 3 shows the structure of BA is salinarum connection with access to the expiry of water.

In Fig. 4 shows the tank in the incision with drainage cavity, covering the outside of the tank, and the valve tip.

In Fig. 5 - section a-a figure 4.

In Fig. 6 shows a tank with valve, equipped with a drainage tube and tip.

In Fig. 7 is a variant of the spherical tank (teardrop) shape.

The mixer consists of a casing 1 (Fig. 1, 2) with valve heads 2 hot and cold water shut-off device 3, a drain tube with a horizontal (extension) part 4, at the end of which is fixed console tank 5, which is the storage capacity for water flowing through the drain tube 4 of the cranes. The tank consists of a body 6 with the saddle 7 and the outlet 8. Inside the housing 6 is placed a spherical valve 9 having positive buoyancy. The dimensions and weight of the valve 9 and the cone angle of the saddle 7 is selected in such a way that the flooding valve 9 water, it did not pop up and held in the saddle, blocking the outlet 8. The housing 6 of the tank is connected with the horizontal part of the drain tube, for example, using threads with subsequent locking of the nut 10. Inside tank 5 is placed drainage system connecting the upper inner part of the space is lost 11, passing or inside the protrusion 12 made directly with the housing 6 (Fig.3), either in the form of an annular cavity 11 (Fig. 4, 5, 6) formed by the covering body 6 of the casing 13. The annular cavity 11 are communicated with the discharge cavity 14 formed by a separate curved pipe 15 (Fig.3), or with the annular space formed covering the housing 6 of the lower part 16 of the casing 13. The discharge cavity 14 is wrapped treniruemsia air flow in the side space 17 of the atmosphere located outside of the flow of water in the area of its expiration. On top of the tank 5 is closed tight by a cover 18, which is connected directly with the housing 6 of the tank (Fig.3) or with a casing 13 of the tank (Fig. 4, 5, 6).

To ensure a uniform gap between the housing 13 and the housing 6 on the casing 13 made the tabs 19 and 20 (Fig. 3, 4, 5, 6). In tanks, is shown in Fig. 4 and 5, the valve 9 provided with a hollow tip 21, and Fig. 6 - advanced drainage tube 22 with an opening 23, which she reported inside the valve with the tip opening. The valve 9 in conjunction with the handpiece, and together with the tip and the drainage tube has a positive buoyancy. The length of the tip 21 is selected so that at the extreme upper position of the valve 9 Nienke at maximum valve lift 9 cover 18 provided with a hollow protrusion 24 with a blind hole. Tip 21 provides convenience for draining the water from the tank at any arbitrary point, and the drain pipe additional trenirovka air to the above-described drainage system through the cavity 11 and 14.

To reduce weight and reduce the complexity of the manufacturing parts of the tank it is recommended to make from nonmetallic materials with low specific weight by a pressing method in multi-piece molds. For this purpose it is recommended spherical (teardrop) shape of the tank (Fig.7) with a horizontal or inclined, as shown in Fig. 7, the plane of the connector housing with a lid. It should be noted that the drainage system is made in the form of an annular cavity 11 (Fig. 4, 5, 6, 7), more preferred, because the discharge of water through the drainage system will be uniform around the circumference of and coaxially to the tank.

The operation of the mixer is as follows.

In mode water saving small opening valves 2, water is supplied through the drain tube into the housing 6 of the tank. The valve 9 under the action of its weight is in the saddle 7 and continues to remain in it at the time of water supply due to the above-mentioned performance of the valve and seat, blocking the outlet 8 is prostranstvo 17 ambient air, located outside of the flow of water in the drain area. The accumulation of water in the casing 6 is until, until you open the outlet 8. Otherwise, after filling the casing 6, the water flows into the drainage system, and starts a small discharge of water through the cavity 11 and 14 in the space 17 in the zone of discharge of the outlet 8. The housing 6 is completely filled with water, and the volume of discharge through the drainage system is equal to the volume of water enters the tank.

To ensure immediate (instantaneous) discharge of water from the housing to cut off his hand or finger (POS. 25 Fig. 3) the outlet 8 or lift the handpiece 21. Such exposure can be performed at any stage of the filling of the casing 6. The valve 9 is opened automatically (Fig. 3) or force (Fig. 4, 5, 6) and because of the positive buoyancy floats up to the level of the accumulated water in unit 6. Starts volley of drain water in the volume of accumulated water in unit 6, so as to be raised when the discharge air discharge air in the upper part of the tank freely compensated by the flow of air through the drainage system in the opposite direction inside the tank. The stream drained water does not prepay the second tube 22 provides additional trenirovka in the accumulation of water, and in the process of draining the drainage occurs in the flow of water, but nevertheless it provides minor additional trenirovka and at discharge. After draining valve 9 descends and closes the outlet 8. The tank is designed for a maximum accumulation of water in the amount of handfuls hands of an adult (about 50 - 70 cm3). Accordingly, the drain water will vary in the range from zero to the specified 50 - 70 cm3. The magnitude of the drain depends on at what point the accumulation of water produced plums, and the dwell time depends on the degree of opening of the mixing valves. In the process of draining the reservoir involved and part of the water located in the discharge tube at the level of the water in the tank. In the absence of effects on the valve 9 (overlapping the outlet 8 or lifting lug 21) after completing the housing 6 there is a continuous expiration through the drainage system in the amount of water enters the tank, i.e., depending on the degree of opening of the mixing valves.

When working in the mode of continuous, intense plum, you need the valve 9 to withdraw its extreme upper position above the influence. In this case, the discharge will occur through the outlet 8, and if the entry is the system.

Both water flow interlock with each other for the area draining the water from the outlet, creating a great overall stream. The valve 9 will be in its extreme upper position.

If the supply of water in the tank (when raised to the top of the valve 9) is less than the amount of discharge through the outlet 8, in this case, the valve 9 will gradually fall down to the saddle 7, and will start to decrease the flow area between the valve 9 and the surface of the seat 7. With this reduction section reduces the drain and the moment comes when the drain becomes equal to the volume of water enters the tank. Further, this equilibrium state or maintained and the valve 9 is kept afloat, to allow water to pass into the outlet 8 and providing continuous disappearance, or the valve 9 is delayed by the flow of water and covers quite a hole 8. In this case, the water fills the casing 6 and merges already through the drainage system, ensuring continuous after (until will not produce effects on the valve 9, and will you raise it up).

Thus, the proposed design of the mixer can be used in the following modes:

- in the economical use of water by nakanojo use of water by continuous small discharge of water in the continuous volume of its receipt of gates;

in the regime of intensive continuous drain any maximum range of plum.

Existing faucets provide in the last two of these modes, therefore, the proposed mixer saves automatically all operational characteristics of existing faucets without any further action and at the same time allows you to save substantially water without deterioration of the product properties by providing opportunities instantaneous discharge at any time with accumulation of water during technological breaks in its use. This mode of operation of the mixer remotely resembles the work of a famous and very economical in the use of water basins, but unlike basins do not need to manually fill the sinks with water, does not require permanent retention of the nipple (tip) hand in the discharge process (need only a little push on the tip or just momentary overlap of the hand of the outlet): there is a possibility of many small and many large continuous automatic drain.

Thus, the proposed mixer, while preserving the positive characteristics of the basins, the firs.

In addition, the proposed mixer is easy to make, using all existing faucets, replacing only the drain tube to the drain tube to the tank (with the possible use of even existing drain pipes by their revisions). Simplifies the design of the drain tube by eliminating one bend with a flared end. Excluded in the discharge tube bend significantly compensates the weight of the tank, made of a material smaller in specific weight, about 8 times compared with steel, which is the drain tube.

The use of the proposed mixer creates the opportunity to significantly save water to the consumer without compromising consumer and operational properties inherent to existing faucets.
