Abstract

Le piston selon l'invention comporte une tête ayant un élément résistant à la chaleur 2, la tête de piston comportant aussi un support 4 en matière différente de celle de l'élément résistant à la chaleur, l'élément résistant à la chaleur et le support étant rivés l'un à l'autre par des rivets 3 et le support étant fixé au corps de piston 5, par exemple par soudage au faisceau d'électrons ou par liaison par diffusion. L'invention permet d'obtenir un piston ayant une tête de piston résistant à la chaleur en matière non apte par elle-même à la liaison au corps de piston.
