Device to limit fire hazard within a turbo machine

The device is installed inside a cavity (70) within the hot gas supply of a turbine (20) and is attached to the drive shaft (10). A pump, which connected to an element of the drive shaft, enables to ergot the main pipe of the circuit when the supply has an excess of pressure for the motor. There is...

Zusammenfassung:	The device is installed inside a cavity (70) within the hot gas supply of a turbine (20) and is attached to the drive shaft (10). A pump, which connected to an element of the drive shaft, enables to ergot the main pipe of the circuit when the supply has an excess of pressure for the motor. There is a leakproof closure (50) arranged next to the drive shaft, for disconnecting the hot gas from the drive of the turbine when the ergot records an excess of pressure. The cavity in the hot gas supply comprises a second cavity (75) for the return of the hot gas. The second cavity is connected to a first outlet (72) having a calibration element (73). The ergot pipe comprises also a cavity (1) arranged for the return of excess hot gas, with the cavity connected to second outlet (82) having second calibration element (83). The leakproof closure is arranged next to the drive shaft, between first and second dynamic seals (51,52;53,54), forming a dynamic device (90) to contain the expansion of the flame within the cavity.
