Abstract
In a hydraulic rodless cylinder type actuator, a piston is movable back and forth in a hydraulic cylinder. Housing elements are respectively mounted on the opposite ends of the cylinder. Parallel output shafts are respectively accommodated in the housing elements and protrude therefrom in a fluid-tight condition. The linear movement of the piston is translated into the rotation of the output shafts by flexible inner power transmission elements. Flexible outer power transmission elements are provided on the protruding ends of the output shafts in order to deliver a high output from a high-pressure chamber defined in the cylinder to the outside of the cylinder.
