Abstract

1,068,195. Pistons. A. CORNET. Aug. 19, 1964, No.33913/64. Heading F2T. In an internal combustion engine piston comprising a cast head 1 and a separate skirt 2, the head includes a crown 3 and a ring-carrying annulus 7 and the gudgeon pin bosses 5 are integral with and supported from the crown 3. The skirt 2, which is of sheet steel, is connected to the annulus 7 by welding or brazing and is supported in the thrust areas by strips 9 integrally extending from the annulus 7 and connected to the bosses 5 by cross-pieces 10. A protective ring 13 of heat-resisting material, e.g. steel, which may be chromium-plated, is housed in a groove in the piston between the parking rings 11 and the top surface of the piston head. A U-section oil scraper ring 12 fitted in a groove 14 has oil return passages 17 communicating with holes 17a in the piston.. A sleeve 19 and an element 18 forming an oil trough 28 are located in the piston as shown and, in operation, oil removed from the cylinder wall by the ring 12 passes through the passages 17 and holes 17a in the trough 28 from whence it is thrown against the underside 4 of the crown 3 to act as a coolant before returning to the sump.
