<p>The regulator according to the disclosure is characterized by a high-pressure piston (1) disposed in the high-pressure chamber (2) which projects into the second chamber (4) through the first aperture (22) and is displaceable in its longitudinal direction therethrough, a second aperture (36) in that end of the high-pressure piston (1) which is turned to face the second chamber (4), in which second aperture (36) the valve seat (3) is disposed, and a channel (33, 31) in the high-pressure piston (1), which extends from the second aperture (36) throughout the entire high-pressure piston (1). The regulator is primarily intended to provide a warning device with a constant gas flow when the pressure in a gas supply has fallen to a predetermined level. It may also be used to ensure a constant gas flow to, for example, an emergency escape breathing apparatus.</p> |
