Abstract
Le corps du détendeur comporte à une extrémité un orifice d'admission de gaz à haute pression et à l'extrémité opposée un orifice de sortie de gaz à basse pression. Une cloison radiale fixe et une cloison radiale mobile axialement délimitent avec l'extrémité correspondante du corps du détendeur une chambre de gaz à haute pression et une chambre de gaz à basse pression et, en outre, entre elles une troisième chambre communiquant avec l'atmosphère environnante Ces cloisons sont pourvues d'alésages centraux alignés axialement que traverse une tige tubulaire, guidée en coulissement axial, dans l'alésage de la cloison fixe, et réunie à l'alésage de la cloison mobile. L'extrémité de la tige qui pénètre dans la chambre de gaz à haute pression en traversant la cloison fixe coopère avec un élément fixe formant siège de soupape Des moyens de rappel élastique agissent sur la tige de façon à l'écarter du siège de soupape.
