摘要

Fuel injection system, in order, under pressure, fuel gas of a fuel chamber (2) of a gas turbine, with a to the fuel chamber (2), leading to the gas supply pipe (15), in which at least one main valve (3, 4) is arranged, and having a control valve (5), which at its upstream end behind the main valve (3, 4) with the supply line (15) and at its downstream end with a line (17), which in an ignition flames - chamber (19) within the combustion chamber (2) is connected, characterized in that a first and a second main valve (3, 4) in parallel in the supply line (15) are arranged and the at least one switching valve (5) to the supply line (15) behind the second main valve (4) is connected, that the two principal valves (3, 4) are electrically controllable solenoid valves, which operate with a pulse widths - modulation, i.e, the gas stream by varying the length of their opening time pulses in relation to their closing time control, and in that the main valves (3, 4) is opened and closed with the same frequency..
