Abstract

Die Erfindung betrifft einen Kolben für eine Brennkraftmaschine, wobei der Kolben aus einem Basisteil (1) und einem daran angebrachten Ringabschnitt (3) besteht und das Basisteil (1) mit dem Ringabschnitt (3) einen Kühlkanal (7) bildet. Dem Kühlkanal (7) wird über eine Öffnung ein Kühlmedium zugeführt. Dieser Kolben ist dadurch gekennzeichnet, daß nach der Endbearbeitung des Kolbens zwischen dem Basisteil (1) und dem Ringabschnitt (3) zumindest eine Öffnung, insbesondere ein umlaufender Spalt (6), vorhanden ist.

The invention relates to a piston for an internal combustion engine, the piston consisting of a base part (1) and a ring section (3) attached to it and the base part (1) forming a cooling channel (7) with the ring section (3). A cooling medium is supplied to the cooling channel (7) via an opening. This piston is characterized in that after the piston has been finished, at least one opening, in particular a circumferential gap (6), is present between the base part (1) and the ring section (3).
