Abstract
A pressure compensating valve mechanism for a hydraulic control valve, having a port through which excess supply fluid is diverted to tank by the valve element thereof in any metering position of the control valve spool. A pressure control mechanism connected with the excess fluid port of the pressure compensating valve mechanism governs flow of excess fluid to tank and minimizes jet forces on the pressure compensating valve element to thereby assure the desired precise control over the motor governed by the control valve.
