Title
(DE) KOLBENRING FÜR EINE BRENNKRAFTMASCHINE
(EN) PISTON RING FOR AN INTERNAL COMBUSTION ENGINE
(FR) SEGMENT DE PISTON POUR UN MOTEUR À COMBUSTION INTERNE
Abstract
(DE)
Kolbenring für eine Brennkraftmaschine, beinhaltend eine Lauffläche (2), eine obere (3) und eine untere Flankenfläche sowie eine innere Umfangsfläche (4), wobei zumindest eine dieser Flächen mit mindestens einer nach Art einer Matrix ausgebildeten Markierung (6) versehen ist, dadurch gekennzeichnet, dass der die Markierung beinhaltende Flächenbereich (7) zur Erzeugung einer Hintergrundfläche für die Matrix (6) heller ausgebildet ist als die zumindest außerhalb der Matrix unmittelbar daran angrenzenden Flächenbereiche des Kolbenringes.
(EN)
Piston ring for an internal combustion engine, comprising a running surface (2), an upper (3) and a lower flank surface and an inner circumferential surface (4), wherein at least one of said surfaces is provided with at least one marking (6) which is formed in the manner of a matrix, characterized in that the surface region (7) which contains the marking is of brighter configuration in order to produce a background surface for the matrix (6) than the surface regions of the piston ring which immediately adjoin it at least outside the matrix.
(FR)
L'invention concerne un segment de piston pour un moteur à combustion interne comprenant une surface de roulement (2), une surface de flanc supérieure (3) et une surface de flanc inférieure ainsi qu'une surface périphérique intérieure (4). Au moins une de ces surfaces est pourvue d'au moins un marquage (6) conçu à la manière d'une matrice. Le segment de piston est caractérisé en ce que la zone de surface (7) contenant le marquage est conçue plus claire que les zones de surfaces du segment de piston se trouvant en dehors de la matrice et directement adjacentes à celle-ci pour produire une surface de fond pour la matrice (6).
