ABSTRACT:
A pressure regulator has a first and a second chamber which are separated by a movable piston varying the size of the chambers and which are in fluid contact with one another through a channel extending in the movable piston. The piston has a greater pressure surface area in the first chamber than in the second chamber. A high-pressure chamber beneath the bottom of the second chamber, has an aperture disposed in the bottom of the second chamber. A valve seat is disposed in the second chamber and cooperates with the movable piston to form a throttle between the high-pressure chamber and the second chamber. A high-pressure piston disposed in the high-pressure chamber projects into the second chamber through the first aperture and is displaceable in its longitudinal direction therethrough. A second aperture is provided at the end of the high-pressure piston which faces the second chamber. Also, a channel in the high-pressure piston extends from the second aperture throughout the entire high-pressure piston. The regulator may include a warning device. It may also be used to ensure a constant gas flow to, for example, an emergency escape breathing apparatus.
