A piston for an internal combustion engine, particularly for motor vehicles. An oil-collecting chamber is disposed between the pin bosses above the pin boss bore. Oil collects within the chamber and is directed down onto the pin bosses, during reciprocating motion of the piston. The width of the chamber is approximately the same as the diameter of the pin boss bore.
