Abstract:
PCT No. PCT/NO94/00160 Sec. 371 Date May 9, 1996 Sec. 102(e) Date May 9, 1996 PCT Filed Oct. 4, 1994 PCT Pub. No. WO95/09674 PCT Pub. Date Apr. 13, 1995A gas regulating valve, especially for use in breathing valves for diver masks and the like. The valve comprises a sleeve-shaped housing (1) having an inlet chamber (I) and an outlet chamber (II), a main valve body (2) cooperating with a seat (3) separating the inlet chamber (I) from the outlet chamber (II), a piston (12) or the like separating the outlet chamber (II) from a servo chamber (III), and a control valve (5,6) arranged to be opened and closed by the main valve body (2). The control valve (5,6) causes a controlled gas flow to the servo chamber (III), which entails that the main valve body (II) is forced to move such that the seat (6) of the control valve at all times rests sealingly against the valve body (5) of the control valve.
