Patent ID: 7628174

Claim:
A hydraulic control arrangement for the load-independent control of a consumer with a continuously adjustable distribution valve comprising: a metering orifice; and a pressure compensator including a stepped pressure compensator piston having an outer annular face, a rear pressure chamber and an annular damping chamber connected via a damping nozzle to an adjacent pressure medium containing chamber, wherein a control pressure acting on the stepped pressure compensator piston in a closing direction of the piston can be applied to the pressure chamber and to the damping chamber, a pressure downstream of the metering orifice in an opening direction of the piston is applied to the outer annular face of the stepped pressure compensator piston, a connecting recess is provided between the rear pressure chamber and the damping chamber, and a check valve opening toward the damping chamber is allocated to the connecting recess, the connecting recess having a larger cross-section than the damping nozzle, such that movement of the pressure compensator piston in the opening direction in response to the damping nozzle cross-section is relatively strongly damped, while in the closing direction the check valve opens and thus controls the larger cross-section to be opened.
