ABSTRACT:
A fluid operated apparatus having a cylinder assembly, a piston and a rod is illustrated wherein cap members are provided with a first circumferential groove and a reduced end portion while a second circumferential groove is carried opposite the first circumferential groove within the cylinder assembly forming a seat for a deformable ring. A method of assembling the fluid operated apparatus contemplates inserting an end cap into the cylinder and then mounting a deformable ring in an adjacent groove in the cylinder and then forcing the cap out so that the ring passes over a reduced conical end portion of the cap and is positioned in the seat formed between the opposed grooves for deforming the ring. Improved cushioning against shock and noise is provided by an air distribution system within end caps having enhanced stability.
