Abstract

698,346. Pistons. HYMATIC ENGINEERING CO., Ltd. Oct. 31, 1951 [Dec. 13, 1950], No. 30420/50. Class 122(i) A piston a of a fluid operated jack having peripheral grooves b, d to receive a sealing ring and lubrication wipers, has on its peripheral surface sleeving c of rubber or plastic which extends to opposite sides of the groove b having the sealing ring therein. The sleeving may, as shown, cover opposite sides of the groove b or may extend over the sides and bottom of the groove b or may be confined to the periphery. The sleeve may be of plastic sold under the Registered Trade Mark " Fluon " or of Polythene. The jack cylinder is of aluminium or magnesium alloy.
