Abstract: A sealing construction in which a sealing ring is carried by a piston spacedly surrounded by a cylinder. The sealing ring comprises portions extending outwardly from its outer peripheral surface into sealing engagement with the inner peripheral surface of the cylinder, and comprises a plurality of layers of a textile material adjacent the portions engaging the inner peripheral surface of the cylinder and out of engagement with the latter. The layers of textile material serve to increase the abrasion resistance and a better lubrication adhesion.

Abstract: A RADIAL SEALING RING WHICH SURROUNDS A ROTARY SHAFT IS PLACED BETWEEN A SUPPLY OF HYPOID OIL OR ANOTHER LUBRICANT WHICH CONTAINS ADDITIVES TENDING TO FORM DEPOSISTS ON THE SEALING LIP OR LIPS OF THE SEALING RING AND/OR ON THE SHAFT, AND A MIXTURE WHICH IS EFFECTIVE TO EITHER PREVENT THE FORMATION OF OR TO DISSOLVE THE DEOPOSITS ON THE SEALING LIPS OR EDGES OF THE SEALING RING AND/OR ON THE ROTATING PART WHICH IS ENGAGED BY THE SEALING RING. THE MIXTURE CONTAINS 43 PERCENT BY WEIGHT OF HYDROCARBONS, 35 PERCENT BY WEIGHT OF BARIUM METAL SOAP, 13.5 PERCENT BY WEIGHT OF A ZINC-CONTAINING COMPOUND OF THIOPHOSPHORIC ACID, 8 PERCENT BY WEIGHT MONTMORILLONITE AND 0.5 PERCENT BY WEIGHT OF ACETONE.
