Abstract
A pressure compensated hydraulic valve (2) is provided with a housing (4) having a reciprocal spool (6) for communicating hydraulic fluid to work ports (8, 10). Pressure compensating means (58) is provided in the same housing with the valve and senses work port pressure by hydraulic fluid flow through the spool from the work port and creates a substantially fixed differential pressure across the spool by controlling the pressure after the flow has passed through the spool. In a multisection valve, the higher work pressure is communicated via passages (28,34,38) and check valves (24,36) to act on pump (46) (via 42) and compensating valve (58). <IMAGE>
