<p>A pressure regulator has a plug (26) dividing the housing (12) into upper and lower chambers, which are connected by a vent (36). A yoke (42) is adapted to selectively close a fluid path (47) in the plug (26). A diaphragm (58) located in the upper chamber (61) responds to outlet pressure against a bias spring (64) to open the plug (26) as the outlet pressure decreases. A second bias spring (112) may also be included.</p> |
