PURPOSE:To suppress a temperature drop in a turbine chamber, by providing high temperature gas supply ports in a case of the turbine chamber and supplying high temperature gas to the high temperature gas supply ports. CONSTITUTION:High temperature gas supply ports 15 are concurrently provided to a case 14 in a turbine chamber 5 over the periphery of the turbine chamber 5, and a branch flow path 10, communicating a combustion chamber 3 to the high temperature gas supply ports 15, is provided in a housing 11, while a flow regulating device 16 of rotary ring type, butterfly valve type, etc. is provided in an inlet of the branch flow path 10 in an artificially adjustable state of opening. In this way, if the high temperature gas supply ports 15 are concurrently provided fully circumferentially of the turbine chamber 5, a total temperature drop of the turbine chamber 5 can be sufficiently and surely suppressed. |
