Abstract

975,225. Piston rings. PERFECT CIRCLE CORPORATION. Oct. 31, 1963 [Nov. 19, 1962], No. 43008/63. Heading F2T. A piston-ring assembly for an I.C. engine comprises a space-expander 12 which is arranged to engage and force outwardly two rings 10, 11 and consists of a plurality of circumferentiallyspaced axially-extending support members 21 connected by U-shaped spring members 22, the arms of which decrease in cross-section from their connection with the support members so that, under load, a uniform stress exists throughout the length of each arm whereby the area at each section of the arms corresponds to the load imposed on that section. The inner peripheries of the rings, which are preferably made of spring steel, are engaged by slanting tab portions 24 on the members 21 and urged against the sides of the piston groove 13 as well as radially against the cylinder wall; some of the tabs 24 may be provided with portions 26 bent inwards. The outer peripheries of the rings are engaged by projections 27 on the members 22. The spacer-expander is of split form with one end of barbed construction engaging in a hole in the other end. Oil scraped off the cylinder wall passes through openings 23 and around the arms and is drained through an outlet 16 leading from the bottom of the groove to the interior of the piston.
