Abstract

403,390. Pistons. OUBRIDGE, W. A., Parklands, Park Road, Coventry. June 18, 1932, No. 17263. [Class 122 (i).] A bi-metal piston comprises a part a of castiron or steel provided with gudgeon pin bosses a<2> ; the body b of aluminium or aluminium alloy is cast around the part a, and is provided with bosses bl which enclose the bosses a<2> and extend inwardly of them ; the gudgeon pin thus keys the two parts together. The piston ring grooves may be formed in the part b or in the part a which does not then extend to the bottom of the skirt. The portion a may be formed with projections or recesses so that when the other part is cast on it metal will flow in or around them, so locking the parts firmly together. Additionally or alternatively, a corrugated ring c of steel may be introduced between the parts a, b, to take up the clearance which occurs due to the different coefficients of expansion of the two parts.
