Abstract

The priority valve can find application in hydraulic circuits for steering of different machines, in particular heavy transport vehicles. The valve has simplified, compact and safe design. It ensures quick reaction of the steering control in case of a sharp change of the operational conditions, such as sudden appearance of heavy loading. The valve comprises of a casing (4) with regulating piston (22) fitted in it. The spring-loaded side of the control valve (29) is connected to a pressure space of the non-spring loaded side of piston (22) of the main valve (3). 2 claims, 4 figures
