Abstract:

A combination air regulator and sensor assembly includes a head including a first chamber having an inlet and an outlet. A regulator dome including a second chamber is linked with the first chamber through a bore. The second chamber includes at least one outlet. A valve assembly is housed within the bore and moveable between closed and open positions sealing and allowing flow in the bore. A first diaphragm is positioned in the second chamber and linked with the valve assembly. The valve assembly moves in response to a pressure applied to the first diaphragm. A spring contacts the first diaphragm and applies a biasing force to the first diaphragm. A sensor dome including a third chamber is linked with the outlet of the second chamber. The sensor chamber includes a discharge outlet. A second diaphragm is positioned in the sensor chamber.
