DEVICE FOR SUPPLYING FUEL TO A GAS TURBINE ENGINE WITH REGULATED FUEL FLOW RATE

摘要

The invention concerns a fuel supply device comprising a fuel supply duct (126) receiving non-regulated pressurized fuel supplied by a pump (100), a fuel flow rate measuring device (122) in the duct (126), a first valve (124) with controlled variable opening mounted on the supply duct, a control system connected to the flow rate measuring device and to the first valve to control same so as to supply the engine with a desired fuel flow in normal operating condition of the engine, a second valve (134) with controlled variable opening mounted on the supply duct in series with the first, and means for controlling the second valve to enable the engine to be supplied with a reduced fuel flow adjustable in response to a detection of overspeed or overthrust of the engine.
