ABSTRACT:
A pneumatic power nut runner with a rotation motor which is connected to a drive train including a torque responsive release clutch (10) and a disengageable torque non-responsive clutch (11), a pressure air inlet valve (12), and an activation mechanism (49, 50) for automatic power shut-off at the attainment of a desired maximum torque level. The activation mechanism (49, 50) comprises a transversely displaceable latch element (49) provided with a blind bore (54) for permitting closure of the inlet valve (12) and a depression (55) for allowing engagement of the torque non-responsive clutch (11), wherein a transverse displacement of the latch element (49) at the attainment of the desired torque level results in a freeing of the inlet valve (12) for displacement toward closed position and a forcing of the torque non-responsive clutch (11) out of engagement.
