Abstract
794,620. Pistons. OSPELT, G. March 12, 1956 [March 25, 1955], No. 7667/56. Class 122 (1). The piston of an I.C. engine is provided with two split scraper rings 2, 3 which, when inserted in the cylinder, are arranged so that the upper ring is under considerably heavier stress than the lower ring. This effect is achieved by either increasing the thickness of the upper ring or the use of supporting springs with this ring. Oil scraped by the rings is discharged through passages 8, 9 in the skirt of the piston, the passage 8 below ring 2 being of larger bore than the passage 9.
