Abstract
1,003,643. Piston rings. GOETZEWERKE FRIEDRICH GOETZE A.G. July 26, 1962 [Sept. 14, 1961], No. 28824/62. Heading F2T. A piston ring 1, e.g. an oil-control ring in a groove 2 of a piston 3 has two inner, outwardlydiverging surfaces 10, 11 against which two springs 12, 13 bear so as to urge the ring 1 radially outward, each spring being located between a side of the groove and its respective bearing surface on the ring. As shown, the bearing surfaces 10, 11 are frusto-conical in shape and meet at an apex which may coincide with, or be offset from, the diametral median plane of the ring. Alternatively, each bearing surface is arcuate in cross-section. The springs may be of different strengths and there may be more than two springs associated with the ring. In operation, oil scraped from the cylinder wall 6 is evacuated through openings 7, 8 in the ring and out of the groove 2, via a duct 9, into the interior of the piston.
