Abstract
FIELD: mechanical engineering; agricultural and industrial tractors. SUBSTANCE: hydraulic system has pump communicating through suction hydraulic line with hydraulic tank, and hydraulic motor, for instance, hydraulic cylinder. Hydraulic system has also hydraulic control valve unit connected by return hydraulic line with hydraulic tanks through viscous resistance restrictor. Return hydraulic line is additionally connected with suction hydraulic line through spring-loaded check valve. EFFECT: improved thermal conditions of hydraulic system.
Claims (1)
Гидросистема относится к общему машиностроению и предназначена для применения на тракторах сельскохозяйственного и промышленного назначения. Цель изобретения - улучшение теплового режима гидросистемы, Гидросистема содержит насос, сообщенный всасывающей гидролинией с гидробаком, и гидродвигатель (например гидроцилиндр). Также гидросистема имеет гидрораспределитель, сообщенный с гидробаком сливной гидролинией через дроссель вязкостного сопротивления. Цель изобретения достигается тем, что сливная гидролиния дополнительно сообщена со всасывающей гидролинией через подпружиненный обратный клапан.The hydraulic system belongs to general engineering and is intended for use on tractors of agricultural and industrial purposes. The purpose of the invention is to improve the thermal regime of the hydraulic system. The hydraulic system contains a pump connected by a suction hydraulic line with a hydraulic tank, and a hydraulic motor (for example a hydraulic cylinder). Also, the hydraulic system has a control valve in communication with the hydraulic tank by a drain hydraulic line through a viscosity choke. The aim of the invention is achieved in that the drain line is additionally communicated with the suction line through a spring-loaded check valve.
