Abstract

Ein Kolben (10) für einen Verbrennungsmotor ist mit zumindest einem, in einem Kolbenkopf liegenden Kühlkanal versehen, der zumindest je eine Zuflußöffnung (32) und eine Abflußöffnung (34) aufweist. Im Anschluß an wenigstens eine der Öffnungen (32, 34) ist in einer Richtung außerhalb des Kühlkanals ein röhrenförmiger Hohlraum (26, 36) vorgesehen, der weitgehend parallel zu einem Kolbenschaft (20) verläuft, und dessen Begrenzung zumindest teilweise mit einer in Längsrichtung des röhrenförmigen Hohlraums (26, 36) verlaufenden Aussparung (24, 38) versehen ist.
