ABSTRACT:
A gas regulator valve comprising a housing with an inlet and an outlet and a partition wall or the like, which divides the housing into two chambers. The inlet communicates with the first chamber and with the outlet via a main valve. Between the two chambers a pressure equalizing passage for the gas is provided, and between the second chamber and the outlet a narrow channel is provided which has a valve seat facing toward the second chamber. The valve seat cooperates with an externally regulated valve body. When the valve is to be utilized in connection with a breathing valve for breathing masks, it also comprises a respiration sensor in the form of a membrane or the like. Via a link arm system or the like, the movement of the sensing membrane is transmitted to the valve body via a needle or a rod which passes through the channel.
