A fuel metering valve for a gas turbine engine includes a pair of chambers within a body, one of the chambers containing devices sensitive to pressure signals derived from the engine compressor. A control element is connected to the pressure sensitive devices and sealingly extends into the second chamber to control the magnitude of a servo pressure signal which is used to control a variable metering orifice between an inlet and an outlet for the valve. A restricted orifice interconnects the first and second chambers. |
