Abstract

Kolben für einen Verbrennungsmotor mit einem ringförmig angeordneten Kühlkanal, der Zulauf- und Ablauföffnungen aufweist, wobei Kühlöl durch eine Kühlöldüse als freier Ölstrahl über einen Zulaufkanal in die Zulauföffnung und damit in den Kühlkanal zuführbar ist und durch mindestens eine Ablauföffnung über einen Ablaufkanal abführbar ist, wobei der Kühlkanal (2) zumindest drei Öffnungen (3, 4, 5) aufweist, wobei in der Kühlkanalebene gesehen der einen Ablauföffnung (4) gegenüberliegend zwei wechselseitig zu nutzende Zulauföffnungen (3, 5) derart angeordnet sind, daß die Öffnungen (3, 5) in Bezug auf eine durch die Ablauföffnung (4) verlaufende Mittelachse symmetrisch angeordnet sind.
