ABSTRACT:
A gas regulator has a has an internal gas chamber and a solenoid valve that controls gas flow into the clamber. A pressure monitor monitors the pressure in the chamber and controls the operation of the solenoid valve to produce a desired pressure in the chamber. The solenoid control signal is a pulsed signal with a variable pulse width, frequency or both. The pressure maintained in the chamber may itself be varied by altering the set point pressure, for example according to the operating parameters of an engine.
