ABSTRACT:
Pump pressure in a fluid power assisted steering device is regulated through the suction side of the pump to supply pressurized fluid to a servomotor through a fluid pressure actuated steering control valve. A pre-control valve controls pressure in an actuating chamber of the steering control valve in response to displacement of the hand steering wheel to obtain a variation in servomotor pressure that is a linear function of the force applied to the steering wheel up to a cut-out point, above which the servomotor pressure rises sharply to a maximum value.
