Abstract

1501387 Pistons PERKINS ENGINES Ltd 25 June 1975 [26 June 1974] 28269/74 Heading F2T In a two-part construction for an I.C. engine piston, weld interfaces 34, 42 and 36, 44 span a recess 24 or recesses (90, 92, Fig. 4, not shown) so as, on welding up, to form a gallery 52 (96). Upper portion 18 has a combustion chamber 40 and is of stainless steel or heatresistant alloy. Piston ring grooves 20 may be formed therein. Lower portion 12 is of light alloy and has gudgeon pin bosses 16. The welds may be friction welds 46, 48 or particle bombardment methods may be used to heat up the weld interfaces. The weld interfaces (62, 66 and 64, 68, Fig. 3, not shown) may be both plane or one pair may be plane and the other conical. Ducts 54 and 56 are provided for circulating cooling oil through gallery 52.
