hydraulic drives in industries and farming. SUBSTANCE: several throttle valves are fitted in feed tube. Hydraulic impact after raising the impact valve causes successive closing of throttle valves, forming closed chambers between them and series of hydraulic impacts shifted in time. Pressure from closed chambers is transmitted to working chamber via high-pressure pipe lines. Since motion of piston in motor cylinder causes discontinuity of medium. Maximum pressure of hydraulic impact under piston increases. Motor works in two strokes; acceleration and hydraulic impact. EFFECT: enhanced efficiency of use of hydraulic impact energy for setting crankshaft in rotary motion. 2 cl, 2 dwg
