A valve arrangement for supplying gas from a high pressure supply has a pressure reducing arrangement and a suction demand arrangement carried by a single housing 20. The housing is a substantially cylindrical hollow body 24 with an internal partition 22 to define two opposed cavities 36, 52. The pressure reducing arrangement is associated with one cavity and the suction demand arrangement with the other cavity. Each cavity is closed off by a diaphragm 28, 50, which serves to control an associated valve closure member 42, 56 of the presstire reducing and suction demand arrangements respectively. <IMAGE> |
