Control for reversible hydrostatic consumer - has valve with auxiliary pressure controlled pressure limiting valve

摘要

The control is for a reversible hydrostatic consumer, i.e. a hydraulic motor of a vehicle, and has a valve with a slide, to connect the supply side of the consumer to the pump, and the consumer outlet side to a container. Auxiliary pressure-controlled pressure limiting valves are positioned on either side of the valve. The pressure supply conduits of the limitation valves are in contact with a consumer connection, while its outlet conduits are in contact with the connection of the pressure-free container. With a fully extended slide, the pump connection is connected to the control pressure conduit which in turn is connected to the control pressure chamber of the limitation valve, which is connected to the outlet consumer connection.
