Abstract

1442124 Pistons ASSOCIATED ENG ITALY SpA 20 Sept 1973 [20 Sept 1972] 52695/75 Divided out of 1440060 Heading F2T Transverse slots 25 keep skirt 15 cooler, by interrupting thermal conduction from crown 10 to the skirt, so that the difference between its operating clearance when cold and when at the operating temperature may be reduced. The piston, which is formed in one piece with inwardly spaced gudgeon pin bosses, may be of light metal or cast iron.
