Abstract

Coulisse à double action comprenant un mandrin interne et un logement externe. Le mandrin interne est placé de manière télescopique à l'intérieur du logement externe pour définir un espace à fluide entre les deux. Une contrainte ascendante et une contrainte descendante sont espacées l'une de l'autre dans l'espace à fluide. Une vanne ascendante est située dans l'espace à fluide et comprend une première surface d'assise qui entre en contact avec un épaulement d'étanchéité ascendant dans l'espace à fluide. Une vanne descendante est située dans l'espace à fluide et comprend une deuxième surface d'assise qui entre en contact avec un épaulement d'étanchéité descendant dans l'espace à fluide.
