PURPOSE:To achieve the weight reduction of an engine by rolling a roller interlocked with an actuator inside grooves for a plural number of a valve levers, in a duplex type valve mechanism for controlling the tip clearance of gas turbine blades. CONSTITUTION:A roller 15 interlocked with an actuator is rolled inside grooves for a high-pressure turbine valve lever 13 and a low-pressure turbine valve lever 14. These grooves are made to have a crooked shape, and while the valve lever on one side is fixed, the valve lever on the other side is enabled to move. Thus, since a plural number of valves can be driven by one actuator and one system of piping can be eliminated, the weight of an engine can be reduced. |
