ABSTRACT:
A double-acting piston and a rotatable torque applicator stem are mounted in a torque applicator housing such that the stem is actuated by the double-acting piston. A coupling member is non-movably mounted on the stem and another coupling member is mounted for axial movement thereon, each coupling member including teeth alternately engageable with the teeth of the other coupling member. The movable coupling member includes a radial arm having a free end cooperating with the double-acting piston to cause a reciprocating rotary movement of the axially movable coupling member with respect to the stem. Pressure is alternately applied on one face and the opposite face of the movable coupling member in synchronization with the actuation of the double-acting piston.
