ABSTRACT A metering valve (20) for supplying a turbine engine with a fuel at a substantially constant flow rate in response to operational conditions evaluated by a computer (28). A signal from the computer (28) in the form of voltage pulses is supplied to a solenoid (30). The solenoid (30) regulates the flow of fuel from a control chamber (54) to produce a fuel pressure Px therein. The fuel enters a supply chamber (46) and the fuel pressure P1 thereof acts on the effective area of a first diaphragm (42) to move face (70) on plunger (68) away from seat (38) in opposition to a closing force generated by the fluid pressure Px acting on a second diaphragm (48). A feedback valve (90) regulates the flow of fuel from supply chamber (46) to control chamber (54). By making the size of the first diaphragm (42) one half the size of the second diaphragm (48) when Px is equal to one half of the sum of fuel pressures P1 and P2, an equilibrium condition exists and fuel is supplied to the outlet conduit (40) at a substantially constant rate for distribution to a turbine engine.
