Abstract

Portable emergency breathing apparatus is disclosed which is comprised of a unitary, generally flat manifold having opposite ends and top and bottom sides and a manifold passageway between the opposite ends. Three parallel, laterally juxtaposed compressed gas containers are mounted on the bottom side of the manifold by means of coupling components extending through the manifold from the top side and into internally threaded necks of the containers. Each of the coupling components provides flow communication between the interior of the corresponding container and the manifold passageway, and a shut-off and pressure reducing valve assembly is mounted on the manifold between two of the containers. The valve assembly has upper and lower portions respectively, adjacent the top and bottom sides of the manifold with the lower portion disposed in the space between the necks of the two adjacent containers. The valve assembly controls the flow of gas from the containers to a breathing hose connected to an outlet passageway of the valve assembly and leading to a hood or mask worn by the user of the apparatus.
