Abstract

L'invention porte sur un ensemble piston muni d'un dispositif d'autoréglage et d'autolubrification et comportant deux segments, l'un de compression combinée et l'autre de gestion combinée de l'huile. Le segment de compression comporte un segment principal et un segment auxiliaire en contact par leur côté plat, une entaille étant prévue pour l'huile de lubrification de la zone de contact; de même le segment de gestion combinée de l'huile comporte un segment de compression secondaire et un segment de gestion principal, sa structure étant sensiblement identique à celle du segment de compression. L'ensemble piston ne comportant que deux segments, son poids, son frottement et son inertie peuvent être réduits et son étanchéité et sa puissance accrues, d'où une réduction de la consommation, du bruit et des émissions du moteur
