Abstract
1,202,601. Piston rings. WELLWORTHY Ltd. 24 May, 1968 [26 May, 1967], No. 24743/67. Addition to 1,123,332. Heading F2T. In a piston ring comprising a radially outwardly opening U-section carrier ring 1 expanded by spring means located within the U and bearing against abutment means on the ring 1, the spring means comprises an axially corrugated leaf spring 8 whose radially inwards crests 9 project through openings 4 in the base 3 of the ring. The radially outwards crests 7 of the spring bear against shoulders 6 on the arms 5 of the ring.
