Title (EN) VALVE AND METHOD
(FR) VANNE , ET PROCÉDÉ
Abstract:
(EN) A valve including a housing, a body having an aperture radially therethrough fluidly connecting a volume radially inwardly of the body with a volume radially outwardly of the body, a bulkhead sealedly disposed between the body and the housing, the bulkhead having a port therein, a piston extending through the bulkhead and sealed thereto, the piston having a bias end and a carrier end, a biasing member connected to the bias end of the piston, the piston exposed at a carrier end to fluid pressure from the volume radially inwardly of the body, a port closure operably connected to the piston.
(FR) La présente invention concerne une vanne qui comprend un logement, un corps qui a une ouverture radiale à travers celui-ci qui raccorde de manière fluidique un volume radialement vers l'intérieur du corps à un volume radialement vers l'extérieur du corps, une cloison étanche disposée de manière étanche entre le corps et le logement, la cloison ayant un orifice dans celle-ci, un piston s'étendant à travers la cloison et scellé à celle-ci, le piston ayant une extrémité de sollicitation et une extrémité de support, un élément de sollicitation relié à l'extrémité de sollicitation du piston, le piston étant exposé à une extrémité de support à une pression fluidique en provenance du volume radialement vers l'intérieur du corps, une fermeture d'orifice étant fonctionnellement reliée au piston.
