ABSTRACT:
A pressure operated valve restricts outflow of fluid from a servomotor to which inflow of fluid is controlled by valve elements torsionally interconnected by a torsion bar for limited relative rotation. The pressure operated valve, mounted within one of the valve elements, is displaced by operating pressure of the inflowing fluid in the direction of the outflowing fluid to partially close a return flow valve passage and is under the bias of a spring urging the valve to a position permitting unrestricted outflow through said return flow valve passage.
