ABSTRACT:
A pressure regulator having a housing with an inlet port and an outlet port. A plug is located within the housing and dividing the housing into an upper chamber and a lower chamber, with the upper and lower chamber being connected by a vent. The plug includes a fluid path between the inlet port and the bore. A yoke is adapted selectively close the fluid path in the plug. A diaphragm is located in the upper chamber and is connected to the yoke. A biasing member biases the yoke to open the fluid path through the plug. The diaphragm is configured to move the yoke to open the fluid path when pressure in the lower chamber and vented to the upper chamber through the vent is above a predetermined amount. The pressure regulator can also include a second biasing member used to positively close the fluid path through the plug.
