Abstract
A piston is provided with a boss having a radial bore for reception of a piston pin. The upper portion of this bore receives lubricating oil through an oiling hole extending from a depression on the outer surface of the piston, the depression being open at the bottom and extending downward on opposite sides of the boss. Downward facing inclined walls form the upper limits of the depression and serve to cause flow of lubricating oil into the oiling holes.
