Abstract
A cylinder having a radially movable or pivoting rod slidably received in a floating gland disposed in a cavity or recess in an end cap of the cylinder. Preferably, seals are provided between the rod, gland and recess. Hence, the rod and gland can move radially while a fluid tight seal is maintained between the atmosphere and the interior of the cylinder to retain pressurized fluid therein. Preferably, to facilitate radial movement of the rod and hence the gland in the recess, the forces on opposed faces of the gland are equalized by an appropriate arrangement of seals to define equal surface areas on the opposed faces both of which communicate with the interior of the cylinder.
