Abstract (en)
[origin: US4518003A] The invention relates to a pressure responsive assembly for controlling the supply of gas to a gas appliance. A pressure responsive device includes a sealed air bulb positioned to monitor the pilot flame of the appliance. A capillary tube connected at one end to the sealed bulb has its other end supported in the central channel of a small plug. An expandable diaphragm or membrane, having a central aperture aligned with the axis of the plug, is disposed to bear against a button member positioned between the diaphragm and an actuating lever set to control operation of a gas supply valve. The button member is shaped with channels, grooves or apertures to establish a through air connection between the capillary tube and external air when the diaphragm is in a deflated condition.
