A valve arrangement intended particularly, but not exclusively, for use with a breathing regulator (1) for underwater breathing apparatus includes an outlet side, an inlet (11) through which gas can pass to the outlet side from a source of gas having a pressure above atmospheric pressure, a movable valve means (12) which functions to close the gas inlet, and a servo device (21) for regulating the valve means. The servo device includes a servo housing (21) and two mutually joined arms (24,26). The arms provide a lever effect whereby the supply of air can be controlled with great precision. The simplicity of the lever arrangement imparts a long useful life to the valve arrangement. A breathing regulator (1) which includes such a valve arrangement is preferably made essentially entirely from a plastic material.
Système de soupape, destiné en particulier, mais non exclusivement, au régulateur de respiration (1) d'un respirateur subaquatique, et comprenant un côté sortie, un orifice d'entrée (11) qu'emprunte le gaz pour atteindre le côté sortie d'une source de gaz dont la pression est supérieure à la pression atmosphérique, une soupape mobile (12) de fermeture de l'orifice d'entrée du gaz et un dispositif asservi (21) de régulation de la soupape, qui comporte un boîtier (21) et deux bras se rejoignant (24, 26). Du fait de l'effet de levier desdits bras, le débit d'air peut être contrôlé avec une grande précision. La simplicité du système de levier confère à la soupape une longue vie utile. Le régulateur de respiration (1) où se monte ladite soupape est de préférence entièrement en plastique.
