POST-PRESSURE-COMPENSATED UNITARY HYDRAULIC VALVE

摘要

A pressure compensated hydraulic valve is provided with a housing having a recriprocal spool for communicating hydraulic fluid to work ports Pressure compensating means 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.
