ABSTRACT:
An improved piston construction comprising a piston body having a crown and a depending skirt, a peripheral groove about the body intermediate the crown and the skirt closely adjacent the crown, a grooved insert band in the groove and adapted to receive at least one piston ring, and at least one frustoconical washer in the groove abutting the insert band on the side thereof closest the crown, the washer having its minor base directed toward the skirt and its major base directed toward the crown and being stressed into a substantially planar configuration to store energy to tightly clamp the insert band within the groove to preclude loosening of the band during operation of an engine employing the piston. Also disclosed is a method of fabricating the improved piston construction.
