A piston (1) incorporates spring means (8) acting, in use, between the piston and an associated connecting rod (4) so as to bias the connecting rod away from the crown (2) of the piston. The spring means (8) is constituted by a pair of disc springs (9) whose circumferential edge portions are supported and separated by a substantially annular support member (10, 11), the spring means being located substantially in the region of the piston crown (2). A carrier (5) is positioned within the piston (1), the carrier being slidably mounted within the piston for axial movement relative thereto, and being connected to the connecting rod (4) in such a manner that the spring means (8) permits the crown (2) to move axially relative to the carrier (5).
L'invention concerne un piston (1) comprenant un moyen de ressort (8) agissant, lors de son utilisation, entre le piston et une tige de liaison associée (4), de sorte à contraindre la tige de liaison à s'éloigner de la couronne (2) du piston. Le moyen de ressort (8) est constitué d'une paire de ressorts à disque (9) dont les parties de bord circonférentielles sont soutenues et séparées par un élément de support sensiblement annulaire (10, 11), le moyen de ressort étant situé sensiblement dans la zone de couronne de piston (2). Un support (5) est positionné à l'intérieur du piston (1). Ce support est monté coulissant à l'intérieur du piston pour un mouvement axial relatif à celui-ci, et est relié à la tige de liaison (4) de telle manière que le moyen de ressort (8) permet à la couronne (2) de se déplacer axialement par rapport au support (5).
