Abstract
A gas regulator ( ) is provided for regulating the pressure of a gas flowing from a source ( ) of the gas under pressure to a device ( ) for using the gas. The regulator ( ) includes a housing ( ) and a pressure reducing valve ( ) in the housing for controlling the flow of gas from an inlet ( ) under pressure to an outlet ( ) at a regulated pressure. The pressure reducing valve is controlled by a pressure responsive member ( ) which is displaced by operating feed and bleed valves ( ) coupled to a control chamber ( ) of the pressure responsive member. The feed and bleed valves are operated by a high speed solenoid actuator ( ). The bleed valve is vented to the outlet of the housing from the control chamber which is maintained at a higher pressure. The high speed solenoid actuator ( ) is operated by a controller ( ) for controllably varying the output pressure as desired.
