Abstract

L'invention concerne un segment râcleur pour piston de moteur à combustion interne constitué par une bague d'écartement élastique 4 et un anneau râcleur 5 porté par la bague, logés dans la rainure 2 du piston 1, la surface de glissement de la branche 13 de la bague en contact avec le cylindre 10 étant fractionnée segmentairement de façon à ménager des canaux de passage d'huile 16 de grandes dimensions améliorant la circulation d'huile.
