Abstract

L'invention concerne un piston pour moteurs à combustion interne. Ce piston comporte une partie supérieure 1, qui prend appui, par une surface annulaire intérieure, 8, sur une surface annulaire intérieure 9, d'une partie inférieure 2 du piston, en formant un interstice qui s'élargit vers l'extérieur; selon l'invention, ledit piston présente en outre, à l'extérieur des surfaces annulaires intérieures 8, 9, dans ses parties supérieure 1 et inférieure 2, deux surfaces annulaires extérieures 12, 13, distantes l'une de l'autre, et des goujons 15, après le serrage desquels les surfaces annulaires intérieures 8, 9, ainsi qu'extérieures, 12, 13, viennent totalement en application. Application aux gros moteurs Diesel.
