Abstract
A system for controlling oxidizer intake diaphragms for a gas turbine engine combustion chamber is disclosed having a single, linear actuator for each pair of intake diaphragms. The movable member of each of an adjacent pair of intake diaphragms is connected to a movable piston rod of the linear actuator. A cam mechanism urges the piston rod in a first direction so as to simultaneously move the movable members of each of the pair of diaphragms. Pressurized gases from the combustion chamber act on the piston to urge it in a second, opposite direction. The forces of the pressurized gases also maintain contact between the cam member and the piston to insure accurate movement of the movable members. A plurality of such linear actuators may be disposed around the periphery of the combustion chamber, each actuator controlling a pair of adjacent intake diaphragms. The actuators may be interconnected by a flexible drive shaft to insure uniformity of movement of all of the cam elements in the system. This insures accurate and simultaneous control of all the intake diaphragms.
