Abstract

L'invention a trait à un piston boulonné pour moteurs à combustion interne. Ledit piston comporte une queue entourant la tige et une partie supérieure réunie à la queue par une vis de dilatation, et formant le fond et la zone des segments. La vis de dilatation repose dans la queue sur une douille de dilatation pénétrant dans un alésage de la queue, l'appui entre la douille et la queue se fait par une surface convexe de la douille et une surface concave complémentaire de la queue, le rayon de la surface convexe étant inférieur à celui de la surface concave. Le centre M2 du rayon de courbure R2 de la surface convexe de la douille 4, à la différence du centre M1 de la surface concave de la queue I, est à l'écart de l'axe longitudinal de la douille. Application : notamment aux moteurs à combustion interne.
