Compression ring for piston of heat engine, has open ring of quadrangular section providing upper and lower surfaces which are connected by two lateral surfaces, where height of lateral surfaces is varied between two ends of ring

摘要

#CMT# #/CMT# The ring (1) has an open ring of quadrangular section providing upper and lower surfaces (2, 3) which are connected by two lateral surfaces (4, 6) concentric to an axis of symmetry of the ring. The lateral surfaces have a height varying in a combined manner between two ends (1a, 1b) of the ring. The upper and lower surfaces are inclined with respect to each other. #CMT#USE : #/CMT# Used in a sealing device of a heat engine piston (claimed) for sealing an outer ring groove of the piston in a combustion chamber. #CMT#ADVANTAGE : #/CMT# The height of the lateral surfaces varies in a combined manner between the two ends of the compression ring, thus eliminating leakages through openings of the ring. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a perspective view of a compression ring. 1 : Compression ring 1a, 1b : Ends 2 : Upper surface 3 : Lower surface 4, 6 : Lateral surfaces.
