ABSTRACT:
A piston of a hydraulic ram, actuator or the like for fitting onto an end section of a straight rod with the assembly for fitting into to travel along a center cavity of a cylinder under the urgings of fluid under pressure that is introduced into that cylinder, the invention consisting of a number of piston component elements including upper and lower piston halves; retaining ring sections or halves, that are for assembly as rings in retaining ring grooves that have been formed around the rod end; at least one O-ring groove that includes an O-ring seal fitted therein; a piston spacer; a seal; and a pair of piston bearings, one for fitting over each piston half. In a practice of the method of the invention to assemble a piston onto a rod end, the piston component elements are sequentially fitted together to assemble the piston Which piston assembly can be accomplished in the field by even an untrained operator using only their hands, or using a minimum hand tools, such as a screw driver. With a selection of material, such as a plastic aluminum or steel compound, based upon the material's shear strength, for manufacture of the piston retaining ring halves, the assembled piston can be programmed to fail under a design fluid pressure. Upon which failure the piston will slide freely along the rod, releasing an applied fluid pressure before damage can occur to the rod, hydraulic cylinder or mountings.
