CA 2416218

A pressure regulator has a plug (26) dividing the housing (12) into upper and lower chambers, which are connected by a vent (36). A yoke (42) is adapted to selectively close a fluid path (47) in the plug (26). A diaphragm (58) located in the upper chamber (61) responds to outlet pressure against a bias spring (64) to open the plug (26) as the outlet pressure decreases. A second bias spring (112) may also be included.

L'invention concerne un régulateur de pression comprenant un obturateur (26) divisant le logement (12) en chambres supérieure et inférieure reliées par un évent (36). Une fourche (42), est conçue pour fermer sélectivement un passage de fluide (47) dans l'obturateur (26). Un diaphragme (58) positionné dans la chambre supérieure (61) répond à une pression extérieure contre un ressort de sollicitation (64) afin d'ouvrir l'obturateur (26) lorsque la pression de sortie diminue. Ce régulateur peut aussi comprendre un second ressort de sollicitation (112).
