Abstract

A combined gas release and gas pressure measuring device 2 includes a control orifice capsule 4 fitted to an end portion 6 of a cylindrical housing 3. The capsule 4 includes a chamber 10, of which a first wall 13 separates the interior of the capsule 4 from the interior of the housing 3, and a second wall 11 contains an orifice 12 of a size such that gas may flow through the orifice 12 at a controlled rate suitable for supplying breathable gas to a breathing system. A normally sealed gas delivery tube 15 and a substantially helical Bourdon tube 16 are mounted in the first wall 13 of the chamber 10, with the gas delivery tube 15 positioned axially relative to both the cylindrical housing 3 and the helical Bourdon tube 16. The orifice 12 can thus communicate with both the gas delivery tube 15 and the Bourdon tube 16 via the chamber 10 of the capsule 4. The device 2 is either mounted in, or integral with, a gas cylinder 1 containing breathable gas stored under pressure. In the embodiment described the gas cylinder 1 having the device 2 mounted therein is secured within a breathing bag (34) Fig. 2, (not shown) of a breathing system with the indicator 17 of the Bourdon gauge 16 visible through a transparent window (33) in the breathing bag (34). Gas is released from the cylinder 1 by gripping a knob 22 and moving it to break the seal in the normally sealed gas delivery tube 15. <IMAGE>
