Abstract

493,191. Pistons. MAHLE, H. Feb. 21, 1938, No. 5456. Convention date, Aug. 20, 1937. [Class 122 (i)] In pistons for internal-combustion engines wherein the skirt is separated from the head by a groove below the gudgeon bosses, the skirt is provided with thickened portions forming auxiliary ribs starting from above the gudgeon pin and extending down into the skirt. The piston 1 has a skirt portion 5 separated by a groove 6 below the gudgeon pin bosses. There are auxiliary rib surfaces 3, of a width corresponding to the boss diameter, and there may be in larger pistons additional ribs spaced round the circumference and extending upwardly to within the piston-ring zone. The piston so made may be produced by a pressing operation.
