Hydrostatic valve assembly and hydrostatic control arrangement with the valve assembly

摘要

The hydraulic valve arrangement (1) has hydrostatic loads (2,4) and valve seat with meter-in orifice (28) through which a feed channel (46) and a pump channel (40) is connected. A load-sensing channel is acted upon by a tapped load pressure of the consumer. The load-sensing channel at the metering orifice is closed by the valve seat without leakage from feed channel connected with a return duct (72) or with the pump channel. An independent claim is included for a hydrostatic control system.
