Abstract

Membrane passage key, of the type comprising a conduit or passage of fluid incorporating a support seat of a membrane of electrically deformable material suitable to be supported on said seat to seal the conduit in the condition of closing the key and to be removed from it in the opening condition of the stop valve, this membrane being formed so that it presents a deformation without understanding when applied to the seat, characterized in that said membrane (14) has fluid passages (16)., 19) suitable to be closed progressively when the membrane undergoes said deformation without compression.
