Abstract

Ensemble à piston et segment destiné notamment à un moteur à combustion interne. Il comprend un segment 10 qui comporte deux parois latérales 16 et 18 convergeant vers l'intérieur, et un piston 24 qui présente une gorge périphérique 22 ayant un profil sensiblement complémentaire de celui du segment 10. Les parois latérales 16 et 18 de ce dernier présentent, en section droite, un profil incurvé de manière à établir des contacts linéaires A et B avec l'une ou l'autre des parois correspondantes de la gorge 22 du piston. Domaine d'application : moteurs à combustion interne.
