ABSTRACT:
An actuator operable to serve concurrently or selectively as a rotary actuator and/or as a linear motion actuator is provided, which comprises a piston-cylinder unit (20, 21), a pair of substantially parallel output shafts (22, 22) having axes substantially perpendicular to the central axis of the cylinder (20) and respectively including confined portions sealingly enclosed in the fluid-tight chamber defined by the cylinder and exposed portions projecting via seal means (45) out of said fluid-tight chamber, a substantially non-extensible and substantially flexible shut-in power transmission element (26) fixedly connected to the piston of said piston-cylinder unit at the substantial center thereof and having ends fixedly connected relative to said confined portions of said pair of substantially parallel output shafts (22, 22), and a shut-out power transmission element (27) having ends fixedly connected relative to said exposed portions of said pair of substantially parallel output shafts (22, 22), said shut-in and shut-out power transmission elements (26, 27) in combination with said paired output shafts (22, 22) being operatively associated such that they constitute a complete pulley system to be driven responsive to the reciprocal movement of said piston (21) to transmit linear motion and/or rotational actuating powers.
