Hydraulic path valve with pressure compensation according to quantity distribution principle

摘要

The control piston (12), for control of the pressure medium path between a pressure medium source, a hydraulic user and a tank is axially displaceable in a first housing bore (11). A regulating piston (70) is located in a second housing bore (45), in which, axially displaced, a first housing channel (38) and a second housing channel (18), downstream of the first housing channel, issue. A regulating through-flow cross-section between the second housing bore and the second housing channel is variable. The regulating piston (70) in the closure direction is activated by a load pressure and in the opening direction of the regulating through-flow cross-section by the pressure directly upstream of the regulating through-flow cross-section.
