Pinless piston ring locator

摘要

A piston (12) and split piston (14) ring assembly having a piston ring locator (24) to prevent substantial rotation of the piston ring (14) in a ring groove (16). A notch (32) is provided in a wall of the ring groove (16) and an abutment pocket is formed by the ends of the split piston ring. The piston ring locator (24) is a flattened wire clip within the groove (16) between the piston ring (14) and the wall of the groove. A segment of the clip is displaced into the notch (32) and another segment is displaced into the pocket (38). <IMAGE>
