Abstract
A piston ring for an oblong piston is adapted to be received in a peripheral groove on the piston. The piston ring is split and the gap between the split ends is located at the center of one of two spaced curved sections of said piston ring. A corrugated spring is received in the peripheral groove within the piston ring and a gap between its split ends is positioned adjacent a side section which extends between the spaced curved sections. The corrugations which contact the side section are closer together than those which contact the curved end sections of the piston ring. This construction helps to equalize the pressure of the piston ring against the cylinder at points around the outer surface of the piston ring.
