Abstract

1193584 Making piston rings REGIE NATIONALE DES USINES RENAULT 29 March 1968 [29 May 1967] 15294/68 Index F2T 37E1R A method of making piston rings comprises casting a tube with internal circumferential crenellations 7 and with a smooth external face so that the cavity development, or pipes, 9 is localized in the external annulus 8, and separating the crenellations by turning. The tube is statically cast and as the external annulus 8 solidifies last, the pipes 9 are located therein.
