Abstract
A cylinder assembly may include a cylinder end having a cylinder end opening, a cylinder barrel, a piston, a rod, and a shaft. An opening through the piston forms a sleeve passing through a portion of the piston. The rod extends out of the cylinder barrel and is configured to rotate with respect to the cylinder barrel and the cylinder end. An opening in the rod further forms the sleeve passing through an interior portion of the rod. A protruding end of the shaft passes through the cylinder end opening. A portion of the shaft has a cross-sectional shape corresponding to the cross-section of the sleeve. The protruding end of the shaft is free to rotate within the cylinder end opening in response to a rotation of the rod. The shaft is free to slide within the sleeve in response to an extension or retraction of the rod.
