Title (EN) PISTON RING
(FR) SEGMENT DE PISTON
(DE) KOLBENRING
Abstract:
(EN) Disclosed is a piston ring (1) comprising a main body having a sliding surface (2), an inner peripheral surface and upper and lower flanks extending between said surfaces, wherein the main body is provided with a gap and in particular in the region of its inner peripheral surface has a cross-sectional interruption, and wherein, viewed in the peripheral direction, the sliding surface (2) is provided with varying conicities (α) and/or crownings such that in the region of the gap the conicity (α) and/or crowning is/are less than in the diametrically opposite rear of the ring.
(FR) Segment de piston (1), comprenant un corps de base qui présente une surface de roulement (2), une surface périphérique intérieure et des flancs supérieur et inférieur s'étendant entre ces faces, le corps de base étant pourvu d'une coupure et présentant en particulier dans la région de sa surface périphérique intérieure une variation de section transversale. Vue dans le sens périphérique, la surface de roulement (2) présente des conicités (α) et/ou des bombements variables de telle sorte que, dans la région de la coupure, la conicité (α) et/ou le bombement de la surface de roulement sont inférieurs à ceux dans la partie arrière diamétralement opposée.
(DE) Kolbenring (1), mit einem Grundkörper, der eine Lauffläche (2), eine innere Umfangsfläche sowie dazwischen verlaufende obere und untere Flanken beinhaltet, wobei der Grundkörper mit einem Stoß versehen ist und insbesondere im Bereich seiner inneren Umfangsfläche eine Querschnittsstörung aufweist und wobei die Lauffläche (2) in Umfangsrichtung gesehen, mit sich verändernden Laufflächenkonizitäten (α) und/oder -balligkeiten versehen ist, dergestalt, dass im Bereich des Stoßes eine geringere Laufflächenkonizität (α) und/oder -balligkeit als im diametral gegenüberliegenden Ringrücken gegeben ist.
