Abstract

See full text

An improved piston ring for use as an intermediate piston ring in a piston assembly having three or more piston rings is provided. The piston ring includes a piston ring body which extends through an arcuate shape between opposite end faces. The piston ring body has at least one combustion gas guidance feature for allowing a greater flow of combustion gasses to pass the piston ring body when the piston is moving in one direction and for allowing a lesser flow of combustion gasses to pass the piston ring body when the piston is moving in an opposite direction. This allows for the ring gap at the outer diameter of the piston ring to be minimized without creating flutter in another piston ring above the intermediate piston ring during operation of an engine.
