Abstract
Un régulateur (53) de pression de gaz amélioré par un accélérateur comprend un capot (11) ainsi qu'un corps (12; logement principal) fixés ensemble de manière à maintenir une membrane (13) entre les deux constituants. Un actuateur (16) présentant une paire de canaux de commande (38) et un siège de surpression (32) dans un constituant est relié à la membrane (13) de manière à être déplacé avec et par cette dernière. Un tube accélérateur/à siège (20) présente des surfaces extérieures de guidage (49) servant à guider et à commander son mouvement, il présente également un passage intérieur (52) d'écoulement de gaz dans lequel est monté un disque à siège élastomère (21; élément soupape). Le tube accélérateur/à siège (20) est limité à un déplacement linéaire (action directe) par rapport à un orifice d'admission/siège de soupape (44) par une pluralité de surfaces de guidage (49) constituant une partie intégrante de l'insert d'orifice (44) sur lequel certaines zones de contact (70, 72) du tube accélérateur/à siège (20) peuvent coulisser.
