Abstract

792,922. Piston-rings. LIGHT PRODUCTION, Ltd., and WHITE, P. July 25, 1956 [July 25, 1955], No. 21501/55. Class 122 (1). A piston-ring, particularly an oil scraper ring, is formed from springy strip metal and comprises two thin side flanges 10 integrallyconnected by a web 11 joined to the outer periphery of each flange and inset from the peripheries. The web 11 may be bowed to provide lateral resilience and have a groove to house a helically wound steel wire expander ring 18. The piston-ring is split at 19 and urged outwardly from the piston-groove 14 into contact with the cylinder wall 13 by the ring 18 whose ends abut and are aligned by a pin 20. The bends 12 between the flanges 10 and the web 11 are rounded and preferably chromium-plated and spaced slots such as 31, Fig. 5, are provided in the web to allow passage of oil. The flanges may diverge or be bowed outwardly as they extend from the bends 12. The expander ring may be formed from steel strip 24, Fig. 5, bent first to wavy formation with rounded or flattened crests and then into a circle having radially inwardly or outwardly abutting ends, the strip 24 having a clearance 26 with the side flanges to allow passage of oil. Alternatively, the strip may be a close fit between the flanges and have spaced apertures therein or cut-away portions along its edges.
