The invention relates to plumbing fittings and can be used in household and public shower facilities and bathtubs.

The famous shower head, comprising a housing in the form of a socket, provided with a hole for the supply of water in the cavity, which by a great Foundation closed the aperture is f cylinder with side holes (USSR Author's certificate N 1426645, class B 05 B 1/18, 1987).

When the supply of water to the cylindrical part of the socket it enters into the interior of the funnel and then through the hole in the diaphragm occurs in the space bounded by the cylindrical screen. Thanks to the special shape of the opening in the diaphragm after the water from the hole is in the form of a diverging cone, the base of which is limited by a cylindrical screen. In the space between the conical jet and cylindrical screen through the side of the cylinder bore ejectives the air, saturating water jet gas fixation. When a certain ratio of the height of the bounding camera to the diameter of the holes in the diaphragm are ripple flowing stream, creating an additional massaging effect.

A disadvantage of the known device is the small amplitude and the precarious nature of the pulsation-dependent hydrodynamic characteristics of the expiration of the properties of the working environment and the ratios of the geometric dimensions of the nozzle.

Also known shower head containing a cylindrical housing with an input channel, hermetically mounted in a glass case with a perforated holes in the bottom and concentric with the cylindrical housing Simcoe's certificate of the USSR N 1479117, class B 05 B 1/18, 1987).

This shower head is equipped with a switching device made in the form of installed inside the enclosure can be rotated around the longitudinal axis of the cylindrical element with inlet openings at one end and end-to-end channels within this element. The device is also equipped with a ball off valves installed in the inlet holes with the possibility of contact with the end face of the cylindrical element of the switching device. End-to-end channels are at an angle to the axis of the cylindrical element of the changeover valve is made with arc extensions from the side of the inlet holes. Cylindrical element from the side opposite to the distribution element, provided with a drive for regulating the speed of this element. After leaving the nozzle sequentially and periodically emitted a jet of working fluid's temperature.

The disadvantage of this device is the design complexity and the lack of stability in the work.

Closest to the technical essence and the achieved result of the present invention is a shower head, comprising a housing with an input channel, gment, with the supply associated with a water channel casing, two control channel connected through feedback channels to output channels connected to two reservoirs, two side walls bounding the cavity of the switch, which reported to the food channel, control channels and the output channels (USSR Author's certificate N 1752432, class B 05 B 1/18, 1989).

Water is supplied to the input channel of the casing and enters the channel power jet element. Resulting from channel power stream is deflected to one of the walls of the cavity of the switch and enters one of the output channels, where water flows into the first header and expires under pressure through the holes in the environment. Some water is diverted through the channel feedback through a delay element (long line) to the first control channel. Under the action of the jet flowing from the first control channel, the supply jet is deflected to the opposite cavity wall switch and begins to act in a different output channel. As a result of pressure in the first reservoir and the first feedback channel fall in the other output channel and the second collector is increased. This increases the pressure of the expiration of the second collector who R already to the second control channel, forming therein a control stream, under the action of which the feed stream is returned to its original state. Thus the outputs of the jet element, and hence the collectors are generated periodic fluctuations in pressure and flow expiration.

A disadvantage of the known device is the high frequency fluctuations of the pressure of the discharge from the low transmission delay of signals in the feedback channels and the impossibility of its adjustment, which reduces the efficiency effects of pulsations on the human body.

The aim of the invention is to expand the functionality of the nozzles by eliminating these disadvantages.

This objective is achieved in that the shower nozzle holding body with the input channel, hermetically mounted in a glass case with a perforated holes in the bottom, two manifold and jet element with the channel power associated with the input channel of the housing, two control channel connected through feedback channels to output channels connected to two reservoirs, the feedback channels are interconnected by means of a sealed flexible partitions.

The invention is illustrated at h is s In Fig. 2; Fig. 4 - section G-G of Fig. 2; Fig. 5 - section d-D of Fig. 1.

A shower head includes a housing 1 with an inlet channel 2, which is tightly mounted in the housing 1 Cup 3 with perforated holes 4 of the bottom 5, the first cylindrical charge 6 with one channel 7 feedback on one end and a jet element 8 on the other end, the second cylindrical charge 9 with another channel 10 feedback on one end and a channel 11 for supplying fluid to the other end. Between the ends of the cylindrical circuit Board 6 and 9 from the feedback posted without gap sealed flexible wall 12 (e.g., polyethylene film). Inkjet element 8 has a channel power supply 13, which is connected through a channel 11 for supplying fluid to the input channel 2, two control channels 14 and 15 connected by the channels 7 and 10 feedback with the appropriate output channels 16 and 17 are connected to the manifolds 18 and 19 separated from each other by separator 20, two side walls 21 and 22, bounding the cavity of the switch 23, which reported the food channel 13, the control channels 14 and 15 and the output channels 16 and 17.

Works shower head as follows.

When the water supply to the input channel 2 on channel 11 for supplying fluid Postup and sticks to one of the side walls, for example, to the side wall 21, and enters the corresponding output channel 16. From the input channel 16 jet of water enters the outlet manifold 18 and under pressure flows through the openings 4 into the environment. In the output channel 17, the water is received and the expiration of their collector 19 is not happening. At the end of the water from the output channel 16 part of it is selected in the channel 10 feedback. The pressure in the channel 10 is increased and sealed flexible wall 12 connecting channels 7 and 10 feedback, bending in the direction of the channel 7, wynema from this channel volume V1water corresponding to the square and move the flexible septum 12. In the channel 10 when it enters volume V2water, compensating the movement of a flexible airtight septum 12. When the movement of the partition 12 is stopped, due to structural limitations of the stroke or its finite stiffness, the pressure in the channel 10 increases, and the channel 7 and decreases, resulting in the control channel 14 pressure appears in the control channel of 15 disappears. Arise between the channels 14 and 15 differential pressure switches jet power to the opposite side wall 22. After switching the stream of water enters the output channel 17 and d is l 16 water ceases to flow and the end of the manifold 18 is terminated. At the end of the water from the output channel 17 part of it is selected in the channel 7 feedback. The pressure in the channel 7 feedback increases and tight flexible wall 12 connecting channels 7 and 10 feedback, bending in the direction of the channel 10, wynema from this channel volume V3water corresponding to the square and move partitions 12. In the channel 7 when it arrives volume V4water, compensating the movement of a flexible airtight septum 12. When the movement of the partition 12 is stopped, the pressure in the channel 7 increases, and the channel 10 is reduced. Resulting between the channels 15 and 14 differential pressure switches jet power in its original position. Then the cycle repeats.

Thus, in the process, the jet power jet element 8 periodically switches, modulating the pressure fluctuations at the outputs 16 and 17 and pressure of the outflow stream of water from reservoir 18 and 19 through the openings 4 into the environment. The frequency f of these oscillations is determined by the delay time , i.e. f = 1/, and in the known device:

=p+o.c.< / BR>
wherepthe time for transferring fluid from a supply to output channels;

o.c.the time is responsive is by changingpando.c.quite complex and requires changes to the basic design parameters of the device.

In the proposed decision, the delay time is increased byin:

=p+o.c.+in< / BR>

And timeinmuch more than timeporo.c..

The frequency due to the change timeineasily accomplished by changing the stroke, square or rigidity of the flexible walls, which increases the functionality of the shower nozzle.
