Abstract: A pressure differential controlled valve for use in a two stage servomotor to delay the communication between a second pressurizing chamber and a first pressurizing chamber until compensatory fluid, which is lost from the first pressurizing chamber in the transfer of the development of an operational force from a first diameter on a power piston to a second diameter on the power piston is replaced.

Abstract: A control valve is actuated by a first plunger upon movement of an input push rod to create a pressure differential across a movable wall which produces an output force. The output force is transmitted from the wall to move a stepped diameter piston, the larger diameter of which develops a first pressure force for operating the wheel brakes of a vehicle. When the input force from an operator exceeds the first pressure force, movement of a second plunger interrupts the communication of the first pressure force to the wheels to permit the output force from the wall to further move the stepped diameter piston so that a smaller diameter thereof develops a second pressure force.
