ABSTRACT:
A drive mechanism with a fluid-operable system can be adapted to a general path configuration. The mechanism includes coaxial tubes following a desired path configuration with the inner tube longitudinally slotted in a sealable manner. A fluid-actuated annular piston surrounds the inner tube and operates in the chamber between the inner and outer tubes with a member extending therefrom toward the piston center and extending in the inner tube slot. A flexible force transmission member is provided within the inner tube and extends longitudinally therein, transmitting the motion or force of the piston to a location of use.
