ABSTRACT:
A compact rotary power cylinder including a pair of pistons fitted in a cylinder housing, separating the housing into a first chamber and a pair of second chambers, so as to be reciprocally movable when a pressure impact is supplied selectively to the first and second chambers, and a torque stem provided through the housing perpendicularly to the reciprocal motion of the pistons so as to be rotatable in response to the reciprocal motion, in which a pair of connecting members are provided between the stem and the pistons so as to be movable in a radial direction of the stem.
A relatively large breakaway torque is achieved with such structure.
