Abstract
1378595 Cooling pistons SOC DE ETUDES DE MACHINES THERMIQUES 16 Feb 1972 [16 Feb 1971] 7091/72 Heading F2T A liquid cooled piston 1 has, in its head, an annular cooling chamber 2 and a separate central cooling chamber 8, the latter chamber communicating with the piston interior. As shown in Figs. 1-3, the chamber 8 is formed by the crown 4 and a wall 6 and is closed by a cover 9 having an orifice 11, in the form of a slot, therein, which connects the chamber with the piston interior. The chamber 2 also communicates with the piston interior through an orifice 20 in an internal tube 23. Bosses 12 for a hollow gudgeon pin 14 are supported from the head by ribs 13. Cooling liquid, e.g. oil, is supplied to the interior 15 of the gudgeon pin through a channel 18 in the connecting rod 17 and to the chamber 8 through a nozzle 24 and slot 11 and to the chamber 2 through a channel 22 in one of the ribs 13. The tube 23 and cover 9 ensure the retention of a minimum amount of cooling liquid in the chambers.
