Abstract

A valve assembly suitable for self-contained underwater breathing apparatus used in conjunction with an adjustable buoyancy life jacket has two inlets (30, 62), one outlet (26) and first and second valves (40, 67) which control the flow of air from a respective inlet to the outlet, each valve (40, 67) being controlled to open or close by a respective first and second diaphragm )36, 71) which both experience substantially the same pressure differential but which have a different mechanical resistance from one another so that the assembly automatically directs air to the outlet from one inlet or the other depending on the depression in a diaphragm chamber.
