Abstract

881,932. Piston rings. PERFECT CIRCLE CORPORATION. Aug. 20, 1959 [Oct. 6, 1958], No. 28473/59. Class 122 (1). [Also in Group XXII] A spacer-expander ring 24 for a piston ring, particularly an oil ring, assembly having two rings 23 comprises a pair of axially-spaced independently functioning flat-spring structures 25 connected by struts 26. Each structure 25 comprises a number of ring-supporting members 30 each integrally connected by U- shaped spring members 31 and having abutments 33 which contact the inner edge surface of the rings 23 and are so sloped as to force the rings both radially into contact with the cylinder 22 and axially into contact with the groove 20 in the piston. The spacer-expander, which is made from sheet metal (see Group XXII), may be formed with the members 30, 31 of modified configuration (Figs. 7 and 11, not shown), and with the width of the spring members 31 in the upper structure 25 either wider or narrower than that of the spring members in the lower structure in order that different pressures may be exerted by the two structures on the ring 33. The latter modified contractions of the structure 25 support the rings 23 nearer to the outer peripheries.
