Abstract
A pneumatic power nut runner with a rotation motor which is connected to a drive train including a torque responsive release clutch () and a disengageable torque non-responsive clutch (), a pressure air inlet valve (), and an activation mechanism () for automatic power shut-off at the attainment of a desired maximum torque level. The activation mechanism () comprises a transversely displaceable latch element () provided with a blind bore () for permitting closure of the inlet valve () and a depression () for allowing engagement of the torque non-responsive clutch (), wherein a transverse displacement of the latch element () at the attainment of the desired torque level results in a freeing of the inlet valve () for displacement toward closed position and a forcing of the torque non-responsive clutch () out of engagement.
