o The invention relates to pipe fittings and can be used both in a closed irrigation network and in a water supply system. A hydraulic shock absorber is known that includes a dredger (pump /, suction and pressure pipelines, check valve, a bypass pipe connecting suction and pressure pipes, in conjunction with which the pressure pipe is mounted a check valve. The check valve is provided with an additional pipe with an overlapping rotary disk C3. Disadvantage This device is an unproductive discharge of water at the time and after the hydraulic shock is quenched until the pipeline is completely emptied. Essentially, the effect to be achieved in the invention is a device for extinguishing hydraulic shocks, including a pressure pipe, a check valve, a valve, a drain chamber and a branch pipe connecting the pressure pipe to the drain chamber zj. A disadvantage of the known device is the complexity of the design and interconnection zone between the elements-. The device is applicable only for damping hydraulic shocks in the immediate vicinity of pumping stations. In addition, the known device produces hydraulic shock cancellation by discharging water through the pump, causing the pump impeller to rotate in opposite directions. When the pump is running, if the consumer is disconnected, for example, a sprinkler located behind the non-return valve, the known device does not provide damping water hammer. The purpose of the invention is to increase reliability and simplify the design. devices. This goal is achieved by the fact that in the hydraulic impact device, which includes a pressure pipe, a check valve, a valve, a drain chamber and a branch pipe, the pressure pipe connecting the pressure pipe to the drain chamber; the chamber is made in the form of two elastic tanks, one of which is perforated, the elastic tanks communicating through the restriction device and are located in front of the non-return valve, and the cross section of the non-perforated container is equal to or larger than the cross section of the discharge pipeline; . .. The drawing shows the device section. The device consists of a pressure pipe 1 with a check valve 2. The sections of the pressure pipe before and after the check valve 3 are hydraulically connected to the bypass pipe. house 3. A drainage chamber is attached to the line of the discharge pipe 3, which contains a container of elastic material 4, which is hydraulically connected through a restriction device 5 with a capacity of 6 of elastic material with perforations 7. A valve 8 serves to shut off the water supply to the consumer strokes works as follows. When switching on the supply line, the flow of fluid opens the check valve 2, fills the section of the discharge pipe 1 located behind the check valve 2, and then goes through the valve 8 to the consumer. At the moment of a sudden stop of the pumping station or switching off of the consumer while the pump is running, the check valve 2 will block the cross section of the discharge pipe, and the water hammer will flow through the discharge pipe 3 to the tank 4, increasing its volume (shown in the drawing by the dotted line). From tank 4, water enters perforated tank 6 through constriction device 5. Passage through constricted device 5, water partially loses its energy. From the perforated tank -6 through the holes, the water enters again into the pressure pipe 1, but already into the area before the check valve 2. The volume 4 in the volume prevents excessive pressure from entering the pump. If the energy of the hydraulic impact “fullness” is not extinguished, the increased pressure will slightly open the check valve 2 and the process of extinguishing
