Abstract

La présente invention concerne un piston pour un moteur à combustion interne (1) qui comprend : un corps (11); une gorge annulaire pour l'huile (115) formée sur la surface périphérique externe d'une partie couronne (111) du corps de piston; un canal de refroidissement (17) formé le long de la direction circonférentielle du corps de piston à l'intérieur de ce dernier; et des trous d'évacuation (2) qui relient la surface concave de la gorge du cylindre à huile à la surface interne du corps de piston; et introduit, par un passage d'admission (17A) dans le canal de refroidissement, une huile de refroidissement qui est injectée vers la surface intérieure du corps de piston depuis la partie inférieure du cylindre de moteur à combustion interne et évacue l'huile de refroidissement par un passage d'évacuation (17B), les trous d'évacuation (2) étant ménagés dans une position évitant le passage d'admission (17A) et le passage d'évacuation (17B).
