Figure 1 shows a General view of the device; figure 2-6 - its sections.

The device consists of a connecting pipe 1, the node of the storage chamber 2, the node of the hydraulic cylinders 3, the bottom cover 4.

The connecting pipe 1 is used to connect with elements of pipelines, in particular, it is mounted on a washbasin tap. The connecting pipe 1 comprises an extension sleeve 5 made of rubber or other sealing material, which serves to seal the junction of the pipe and the pipe element. A nut 6 secures the sealing sleeve 5 in the nozzle 1. A screw 7 fixes the nozzle 1 on the washbasin tap. The water supply channel 8 is cylindrical in shape, and directly communicates with the storage chamber 9.

The node 2 of the storage chamber serves to ensure the release of water to the consumer and to supply pressurized water to the hydraulic cylinders of the hydraulic cylinder assembly 3. It contains a storage chamber 9 of cylindrical shape, which serves to create a pressure pressure in the channels 1 of the hydraulic cylinders of the hydraulic cylinder assembly 3. Water is passed through the channel 10 under pressure enters the hydraulic cylinder 11. The throttle 12 is used to control the speed of water supply to the hydraulic cylinder 11. Through the channel 13, pressurized water enters the hydraulic cylinder 14. Through channel 16, water under pressure enters the hydraulic cylinder 17. Through the hole 18, water from the storage chamber 9 enters the outlet chamber 49 and then through the outlet channel to the consumer.

The cylinder assembly 3 serves to periodically open and close the water supply to the consumer. The hydraulic cylinder unit 3 contains three hydraulic cylinders 11,14,17. The hydraulic cylinder 14 serves to open and close the outlet 18

using the cone channel 21 and open and close the drain hole 22 of the hydraulic cylinder 17 using a cylindrical valve 23 made on the rods

the hydraulic cylinder 14. The hydraulic cylinder 17 serves to open and close the drain channel 24 of the hydraulic cylinder 11 by means of a cone valve 25 made on the rod of the hydraulic cylinder 17. The hydraulic cylinder 11 closes and

0 opens the drain channel 26 of the hydraulic cylinder 14 using a cylindrical valve 27 made on the rod of the hydraulic cylinder 11. The hydraulic cylinders have a spring return pistons 28,29,30 using springs

5 31.32.23. The drain channel 24 through the drain chamber 34 and the hole 35 communicates with the environment. The bottom cover is designed to close the ends of the hydraulic cylinders 14.17 and to form a drain channel 22 of the hydraulic cylinder 17 and to accommodate the cylindrical valve 23. Holes 36.37 are used to ventilate the spring chambers of the hydraulic cylinders 11,14,17.

The device operates as follows.

When the nozzle of the device is connected by the nozzle 1 to the washbasin faucet and secured by the fixing opite 7, the valves of the washbasin tap are opened. Water under pressure

0 channel 8 enters the chamber 9. From the camera 9 through the hole 18, the output chamber 19 and the output channel 20 enters the consumer. At the initial moment, the piston 29 of the hydraulic cylinder 14 is in the lower extreme position 5 due to the return spring 32, the piston 28 of the hydraulic cylinder 11 is in the extreme upper position due to the return spring 31, the piston 30 is in the extreme lower position due to

0 return spring 33. The drain holes 22 and 24 of the hydraulic cylinders 11 and 17 are open, the drain hole 26 of the hydraulic cylinder 14 is closed.

Water under pressure through the channel 13 enters the hydraulic cylinder 14 and slowly moves the piston 29 upward, the speed of movement is set by the throttle 15.

After some time, the piston 29 moves up so that the cone valve 21 closes the hole 18, the water supply to the consumer is stopped. When moving the piston 29 of the hydraulic cylinder 14, the cylindrical valve 23 closes the drain 5th hole 22 of the hydraulic cylinder 17.

The hydraulic cylinder 17 is activated and after a while closes the drain hole 24 with a cone valve 25. Water under pressure through the channel 10 enters the hydraulic cylinder 11. The flow rate of water is regulated by the throttle 12. After a certain time in the lower position of the piston 28, the cylinder valve 27 will open the drain hole 26. Under the action of this piston 29 of the hydraulic cylinder 14 due to the return spring 32 is triggered in the opposite direction. The cone valve 21 on the piston rod 29 opens the hole 18, and water enters the consumer.

Upon reaching the lower position of the piston 29, the cylindrical valve 23 opens the drain hole 22 of the hydraulic cylinder 17. The hydraulic cylinder 17 is activated in the opposite direction by the return spring 33, and the cone valve 25 opens the drain hole 24 of the hydraulic cylinder 11. Due to the action of the spring 31, the piston of the hydraulic cylinder moves to the reverse position, and the cylindrical valve 27 closes the drain hole 26 of the hydraulic cylinder 14.

Subsequently, the process is repeated. Thus, the opening and closing of the hole 18 occurs periodically, as a result of which water is supplied to the consumer intermittently (pulsedly).

A device operating according to this principle can be used not only as a run-in on a faucet of a household washbasin, but also built into the equipment of the washbasin and shower.

The device can operate in three modes:

1. Continuous pulse shaping

2. In single pulse mode

3.In continuous water supply mode, the first mode is described above, frequency

pulses are set by dashes 15 and 12. The frequency can be regulated over a wide range.

The second mode occurs when closing the throttle 12.

The third mode occurs when closing the throttle 15.

The throttle 15 contains the functions of a flow meter and can be made in the form of a flow meter, have a scale, a pointer in the form of an arrow, etc.

Due to the fact that the device can operate in three modes, it is convenient to use, it easily switches from one mode to another, and due to the possibility of controlling the pulsation frequency over a wide range, in general, water consumption can be saved when consumed in comparison with the above analogues.
