Abstract
A pressure reducing and filling valve combination for use in conjunction with gas bottles, particularly gas bottles that contain breathing gas under high pressure for use by underwater divers firemen, etc. The valve includes a valve chamber (3) and a spring-loaded valve slide (4) which is movable in the valve chamber and which functions to reduce the pressure with the aid of the spring (9) when gas is taken from the bottle (1) for delivery to a part of the chamber (3). The pressure in this chamber part is therewith held substantially constant at a level determined by the spring force. An external multi-purpose valve connector (15) is adapted to connect the valve chamber (3) to external equipment when gas is consumed. When filling the bottle with gas under high pressure, the valve functions to deliver gas to the bottle via the same passageway (11) as that through which gas was delivered to the valve chamber in response to gas consumption.
