ABSTRACT:
In order to ensure an adequate supply of oil onto the thrust surfaces of a reciprocating type internal combustion engine piston, recesses are formed in the skirt proximate each thrust surface. The boundary defined between the surface of the skirt and the recess is defined by a rounded surface which smoothly merges the recess with the surface of the skirt, eliminates sharp edges, and permits oil to flow uninhibited out of the recess onto the thrust surfaces.
