Abstract
A hydraulically actuated torque coupling assembly that has an actuator plate mechanism integrated within the pressure relief valve assembly. The actuator plate includes a valve closure member and two alignment pins. The valve closure member is disposed adjacent to a valve seat on the face of the torque coupling assembly. The actuator plate and an associated electro-magnetic solenoid assembly are partially enclosed in a stationary housing that is positioned outside the coupling case. A variable amount of electrical current is applied to the solenoid assembly so that the actuator plate valve closure member engages the associated valve seat. The release pressure of the pressure relief valve assembly is selectively based on the magnitude of an electric current supplied to the solenoid assembly.
