Abstract

L'invention concerne un échangeur de pression motorisé (300) comprenant un rotor (310) configuré pour échanger une pression entre un premier fluide et un deuxième fluide. L'échangeur de pression motorisé (300) comprend en outre un chapeau d'extrémité motorisé (330) formant un alésage central. L'échangeur de pression motorisé (300) comprend en outre un arbre (320) comprenant une première extrémité distale couplée au rotor (310). L'arbre passe à travers l'alésage central du chapeau d'extrémité motorisé. L'échangeur de pression motorisé (300) comprend en outre un joint statique (340) disposé contre le chapeau d'extrémité motorisé (330) pour empêcher le fluide de l'alésage central de sortir de l'échangeur de pression motorisé (300) par l'intermédiaire du chapeau d'extrémité motorisé (330).
