Abstract

939,035. Piston packing. REGIE NATIONALE DES USINES RENAULT. Nov. 8, 1960 [Nov. 12, 1959], No. 38323/60. Class 122(1). [Also in Group XXIX] A compressed air actuated piston 3 has a peripheral groove 10 connected by a passage e.g. a radial bore 8 to the cylinder space at one end of the piston and the groove is overlaid by a packing 5<SP>1</SP> having apertures therein communicating with the groove 10 and terminating at the wall of the cylinder 2 against which the packing bears. As shown the apertures are formed in a thin portion 7 of the packing disposed between an inwardly directed lip 6 and an outwardly directed heel 4. A similar packing 5, Fig. 1 (not shown), may be provided at the other end of the piston 3. In a modification the bore 8 instead of opening into a cavity 9 opens into an axial passage 41, Fig. 2 (not shown), which itself opens on the end face of the piston.
