ABSTRACT:
A power drive control unit of a torque control clutch for a fluid operated power tool features a latch, operable for initiating and interrupting motive fluid flow to a rotary fluid motor, and an actuator pin for controlling the latch. The latch is carried on a drive spindle rotatable in synchronism with a driven clutch part and is supported for rotation on that drive spindle. The actuator pin is carried on a driving clutch part for actuating the latch upon relative movement between the driving and driven clutch parts at a predetermined output torque for moving the latch into position to interrupt fluid flow to the motor within less than a single revolution of relative movement between the driving and driven clutch parts.
