Abstract:
1. A gaseous fuel pressure regulating system, comprising: an inlet port; a conduit connected in fluid communication with said inlet port; an outlet port connected in fluid communication with said conduit; an actuator; a first valve disposed between said conduit and said outlet port, said first valve being operable to selectively inhibit or permit gaseous fuel to flow from said conduit to said outlet port, said first valve being movable between a gaseous fuel flow inhibiting position and a gaseous fuel flow permitting position in response to movement of said actuator; a controller connected in signal communication with said actuator, said controller being configured to maintain a desired pressure magnitude at said outlet port, said controller being a microprocessor which is connected in signal communication with said actuator, said microprocessor being configured to provide a signal to said actuator to control the movement of said first valve between said gaseous fuel flow inhibiting and said gaseous fuel flow permitting positions; a pressure sensor disposed in pressure sensing relation with said outlet port, said pressure sensor being connected in signal communication with said microprocessor; and a second valve disposed in fluid communication between said inlet port and said conduit.
