ABSTRACT:
A fluid actuated cylinder assembly including a piston and piston rod and having a cylinder head capable of shifting in any direction throughout 360.degree. along a plane perpendicular to the long axis of the cylinder. The piston and piston rod are rockable throughout 360.degree., the piston maintaining a fluid tight seal with the cylinder at all times. The cylinder, piston rod and shiftable head are preferably made of acetal resin or equivalent thermoplastic material. The piston comprises a sleeve made of acetal resin or equivalent thermoplastic material mounted on the piston rod and having an integral enlarged flange portion with a peripheral surface carrying a seal maintaining a sealing engagement with the cylinder. Alternatively, the piston comprises a spherical rubber member mounted on the piston rod and making the seal with the cylinder. The cylinder assembly can be pneumatically or hydraulically actuated and may be of the single-acting or double-acting type. The cylinder assembly can be fixedly, pivotally or universally mounted. The shiftable head and rockable piston and piston rod preclude reasonable misalignment of the piston rod axis with respect to the axis line of the cylinder from resulting in severe wear of the cylinder head, piston rod and seals causing leakage of air or hydraulic fluid.
