Abstract

L'invention concerne une soupape de réduction de pression et de gonflage combinée destinée à être utilisée dans des bouteilles d'oxygène, notamment des bouteilles d'oxygène contenant du gaz à respirer, sous haute pression, utilisé par des plongeurs sous-marins, des pompiers, etc. La soupape comprend une chambre (3) de soupape et un tiroir (4) de soupape à ressort mobile dans la chambre de soupape et destiné à réduire la pression à l'aide du ressort (9) lorsque de l'oxygène est extrait de la bouteille (1) afin de l'acheminer dans une partie de la chambre (3). La pression dans cette partie de chambre est ainsi maintenue à un niveau sensiblement constant déterminé par la force du ressort. Un connecteur (15) de soupape extérieur polyvalent est adapté pour relier la chambre (3) de soupape à un équipement extérieur lorsque l'oxygène est consommé. Lors du gonflage de la bouteille avec de l'oxygène sous haute pression, la soupape achemine l'oxygène dans la bouteille par le même passage (11) que celui par lequel l'oxygène a été acheminé dans la chambre de soupape en réponse à une consommation d'oxygène.
