Abstract

A ram air turbine hydraulic power system and pressure compensator valve (24) usable therein for controlling the displacement of a variable displacement pump (12) driven by a ram air turbine (10). The pressure compensator valve has a valve member (42) with a pilot responsive to discharge pressure of the pump and a compensator spring (50) acting on the valve member in opposition to the discharge pressure, a movable control piston (54) engaging the compensator spring, a pair of control springs (70, 72) engaging said control piston and acting in opposition to each other, and a control pressure which is proportional to the square of pump speed is applied to the control piston whereby the force of the compensator spring is varied depending upon the position of the control piston.
