Patent ID: 6959536

Claim:
A fuel metering device for varying the supply of fuel from a fuel source to a gas turbine engine comprising: an inlet in fluid communication with said fuel source; an injector outlet; a first chamber in fluid communication with said inlet and said outlet; a solenoid activated plunger reciprocal within said first chamber between a first position and a second position, wherein movement of said plunger toward said first position draws fuel into said first chamber through said inlet and movement of said plunger toward said second position causes fluid in said first chamber to flow through said outlet; a plenum in fluid communication with said injector outlet and a resonator chamber, said plenum having a fuel outlet; said resonator chamber having a first compartment and a second compartment separated by a piston, said first compartment in fluid communication with said plenum and said second compartment in fluid communication with compressed air from said turbine engine; and an electronic controller selectively regulating the rate said solenoid activates said plunger.
