<p>A pressure regulator includes a housing having a chamber that receives a pressure responsive member (30). The pressure responsive member (30) includes an internal charge (90) that allows a movable portion (68) of the regulator to react in response to pressure differentials. A preferred embodiment of the regulator includes a dampening member defined by an o-ring (82) that exerts a drag on the pressure responsive member (30) to address oscillations associated with high flow rates. The dampening force can be varied according to the subject invention. Moreover, a normally planar poppet retaining member reduces manufacturing costs of the regulator and allows for a highly polished surface to address concerns with impurities. A biasing arrangement (120) is also incorporated into the regulator to assure that the poppet (68) seals against the valve seat (70) if the internal pressure charge of the regulator is lost.</p> |
