A fuel metering valve for a gas turbine active combustion control system has a highly responsive pressure balanced valve assembly with either a flapper or clevis member. The valve member is mounted at one end to an armature of a magnetic drive assembly and a movable part of a flexure pivot otherwise fixed to the valve housing. The armature, flexure pivot and valve member are disposed along a main axis. Magnetic flux selectively pulls the armature toward opposite sides of the main axis causing it and the valve member to pivot in the flexure pivot such tha...
I claim: 1. A fuel metering valve capable of operating in an active combustion control system of a gas turbine, the valve comprising: a valve housing having an inlet port and an outlet port; a nozzle passageway disposed between the inlet and outlet port; a drive assembly disposed in the valve housing and having a movable actuator member disposed along a main axis; a flexure pivot mounted to the housing and the actuator member to allow pivoting of the actuator member with respect to the main axis; and a flapper mounted to be disposed along the main axis...
