Title
(EN) HYDRAULIC FLUID ACTUATOR WITH METAL TO METAL SEALS
(FR) ACTIONNEUR A FLUIDE HYDRAULIQUE MUNI DE JOINTS METAL SUR METAL
Abstract
(EN) An improved fluid actuator is provided. The fluid actuator (25) comprises a variable volume fluid chamber (124). A first tube (162) is fixed within the variable volume fluid chamber (124). The first tube (162) has a first sealing surface (142) and a second sealing surface (144). A piston (100) is slidably disposed within the variable volume fluid chamber (124) and slidably movable over the first tube (162) between a first position and a second position. The piston (100) comprises a first sealing surface (140) and a second sealing surface (146). The piston first sealing surface (140) and the first tube first sealing surface (142) cooperate to form a seal between the piston (100) and the first tube (162) when the piston (100) is in the first position. The piston second sealing surface (146) and the first tube second sealing surface (144) cooperate to form a seal between the piston (100) and the first tube (162) when the piston (100) is in the second position.
(FR) L'invention concerne un actionneur à fluide perfectionné (25) comportant une chambre (124) de fluide à volume variable. Un premier tuyau (162) est fixé à l'intérieur de cette chambre (124) et présente une première surface (142) d'étanchéité et une seconde surface (144) d'étanchéité. Un piston (100) est disposé coulissant à l'intérieur de ladite chambre (124) et sur le premier tuyau (162). Ce piston (100) coulisse entre une première position et une seconde position. Ce piston (100) présente une première surface (140) d'étanchéité et une seconde surface (146) d'étanchéité. Cette première surface (140) et la première surface (142) d'étanchéité du premier tuyau agissent ensemble en vue de former un joint entre le piston (100) et le premier tuyau (162), lorsque le piston (100) se trouve dans sa première positon. La seconde surface (146) d'étanchéité du piston et la seconde surface (144) d'étanchéité du premier tuyau agissent ensemble en vue de former un joint entre le piston (100) et le premier tuyau (162), lorsque le piston (100) se trouve dans sa seconde position.
