Abstract: FIELD: mechanical engineering. SUBSTANCE: according to method, amount of liquid is created in chamber under pressure. Outflow of liquid through built-in discharge device is prevented until corresponding required pressure is achieved. Ensured is outflow of liquid from chamber through discharge device until pressure in chamber is increased and outflow hole is opened wide. Discharging of liquid from chamber is effected in the form of pulsing jet until liquid is continuously delivered into chamber at regulated liquid flow at low rate. Due to ejection of liquid, pressure reduction takes place together with reduction of liquid volume inside chamber. This leads to closing of discharge device and completion of one cycle of pulsing flow discharge. Operations are repeated in alternating succession during required period of time with creating interrupted pulsing flow of high rate. In device, resilient pipe tightly embraces bush thus creating tubular lock in this case. In pulsing device, resilient pipe tightly embraces bush with ensuring expansion of chamber due to liquid pressure. Thus passage is created for liquid flow between discharge device of chamber and inlet device in compliance with liquid pressure inside inlet device which exceeds initially preset level. Pipe in discharge device envelops outlet hole in bush. Device is provided with additional body. Located in this additional body are bush and resilient pipe and also unit which creates resistance to liquid flow. Bush is made rigid and has end portions. Resilient pipe is of various diameters and thickness of wall in selected positions over its length. Created at discharge portion of chamber due to quick operation of this portion of chamber is hydraulic impact, and in result, ejection of liquid takes place. Device can be used in irrigation systems. EFFECT: higher efficiency. 9 cl, 2 dwg
