Abstract

FIELD: mechanical engineering. SUBSTANCE: hydraulic system has pump made in form of reversible hydraulic machine and driven by internal combustion engine. Delivery line of pump is coupled through guide distributor with actuating member and drain line. Pump is made to preserve direction of rotation under reversible duty corresponding to direction of rotation of driving internal combustion engine. Hydraulic accumulator is connected to delivery line of pump in parallel with actuating member through additional distributor which places, in one of its working positions, the hydraulic space of hydraulic accumulator in communication with drain line, bypassing guide distributor. EFFECT: possibility of operation at low ambient temperatures. 1 cl, 1 dwg

Изобретение относится к общему машиностроению, в частности к гидроприводам самоходных машин, эксплуатируемых в условиях низких температур окружающей среды. Сущность изобретения заключается в том, что в гидравлической системе, содержащей выполненный в виде обратимой гидромашины насос с приводом от ДВС, напорная линия которого связана через направляющий распределитель с исполнительным органом и сливной линией, насос выполнен с сохранением направления вращения в обратимом режиме работы, соответствующем направлению вращения приводного ДВС, а гидроаккумулятор подключен к напорной линии насоса параллельно исполнительному органу через дополнительный распределитель, сообщающий в одной из своих рабочих позиций гидравлическую полость гидроаккумулятора со сливной линией в обход направляющего распределителя. 1 ил.The invention relates to general mechanical engineering, in particular to the hydraulic drives of self-propelled machines operating in low ambient temperatures. The essence of the invention lies in the fact that in a hydraulic system containing a pump made in the form of a reversible hydraulic machine driven by an internal combustion engine, the pressure line of which is connected through a directional distributor to the actuator and the drain line, the pump is made with the rotation direction in the reversible mode of operation corresponding to the direction rotation of the internal combustion engine, and the accumulator is connected to the pressure line of the pump parallel to the actuator through an additional distributor, reporting in one of its their working positions hydraulic accumulator cavity with a drain line bypassing the directional distributor. 1 ill.
