ABSTRACT:
A hybrid fuel metering system incorporating a multi-function control valve (18) is shown. The valve has a sleeve (96), a piston (98) mounted for translational movement within the sleeve and a spool (100) mounted for translational movement in the piston. The piston has three positions for cooperating with the sleeve; a variable first position for metering fuel to an engine (12), a second position for directing fuel to a metering valve (20) and a third position for shutting off flow to the metering valve and to the engine to correct engine overspeed. The spool has two positions a first position to shut off flow to the engine and to the metering valve to shut off the engine and a variable second position to position the piston to meter flow to the engine.
