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.

Figure 00000001
Piston for an internal combustion engine with an annularly arranged cooling channel, which has inlet and outlet openings, cooling oil being able to be fed through a cooling oil nozzle as a free oil jet via an inlet channel into the inlet opening and thus into the cooling channel and being able to be discharged through at least one outlet opening via an outlet channel, whereby the cooling channel (2) has at least three openings (3, 4, 5), with two mutually usable inlet openings (3, 5) arranged opposite the one outlet opening (4), viewed in the cooling channel plane, such that the openings (3, 5 ) are arranged symmetrically with respect to a central axis running through the drain opening (4).
