ABSTRACT:
A freeze resistant first stage pressure regulator for use with a high pressure source of breathable gas includes a housing and a yoke, for attaching said housing to a high pressure source of breathable gas along with a pressure regulated outlet, a valve seat and a piston. A spring is provided for biasing the piston in order to effect a regulated valve opening between the piston and the valve seat and provide a pressure regulated supply of breathable gas to the pressure regulated outlet. The spring, piston and valve seat are all sealed within the housing. An antifreeze liquid is sealed within the housing for excluding contact of said spring and piston with ambient water; and a pressure transfer device, disposed in a wall of the housing and in fluid communication with the antifreeze liquid is provided for equalizing pressure between the ambient water and said antifreeze liquid.
