Abstract
La présente invention a pour objet un piston monobloc pourvu d'un segment captif qui est logé en même temps qu'une bague d'appui dans une gorge du piston. Elle est caractérisée en ce que les flancs correspondants du collet annulaire 10, du segment 9 et de l'épaulement annulaire 5 de la gorge 3 définissent un profil conique, le flanc conique 6 de l'épaulement annulaire 5 de la gorge 3 s'étendant jusqu'à la périphérie du piston 2. Elle se rapporte aux mécanismes à cylindres et pistons.
