ABSTRACT:
A regulator assembly which receives a variable reference signal to control the fluid pressure of a supply fluid supplied to a motor. The variable reference signal which represents the work performed by the motor also passes through a relief valve. When the output torque of the motor reaches a predetermined value, the relief valve opens and a portion of the fluid supplied to the motor is vented to an exhaust conduit to protect any mechanism operated by the motor from receiving excessive torque.
