Abstract
Gas turbine combustor by-pass valve device for opening and closing a by-pass valve is improved to uniformly control air supply into a combustion area for appropriate combustion. A drive shaft,for opening and closing a driven by-pass valve,is provided in turbine casing,where an outside obstruction is located which would interfere with a projecting drive shaft,. The driven shaft,has a short length to be provided in the turbine casing,. An adjacent main driving shaft,for opening and closing main driving by-pass valve,is provided adjacent to the driven shaft,. Link mechanism,is provided between the adjacent main driving shaft,and the driven shaft,so that rotary movement of adjacent main driving shaft,driven by outside drive means via the drive shaft,is transmitted to the driven shaft,and, thus, to the driven by-pass valve,. Thus, partial drive shafts,are made shorter so as not to project outside of the turbine casing,and interfere with outside obstruction, but all the by-pass valves,provided along circumferential direction of the turbine casing,can be operated to be opened and closed uniformly.
