Abstract
A piston includes a main body extending between a first end and a second end along a center axis of the piston. The main body further includes a chamber formed within the main body, the chamber having an opening disposed at the first end of the main body. The piston also includes a cap, the cap being coaxial with the main body. A portion of the cap extends into the opening of the chamber of the main body. At least one of the main body and the cap includes a radially extending lip, and the other of the main body and the cap includes a groove. A retaining ring is both disposed partially in the groove and in contact with the radially extending lip so as to connect the cap to the main body.
