ABSTRACT:
An electronically controlled fuel system for use with a continuous, non-cyclical process has a fuel manifold to which pressurized fuel from a source is supplied and through which the fuel is metered, to an end use combustor, by a periodically energizable pulse-width modulated, solenoid actuated valve. The pulsed fuel output of the valve is exposed to an accumulator which operates on the output to reduce the amplitude of the pulsations effectively integrating them out of the fuel flow, resulting in a substantially continuous supply of fuel. A purge system may be integrated into the fuel manifold and has a second solenoid actuated valve member which is operable, upon fuel system shut-down, to direct pressurized air through the fuel system to remove excess fuel.
