International ClassF01D 025/12Foreign Application Priority Data1992-02-04 DEAbstractThe wall space and the mounting space for turbine bearings in the casing of an aircraft gas turbine are each supplied with cooling air via a separate pipe, a first cooling-air pipe opening into the wall space and a second cooling-air pipe extending through the wall space and opening in the mounting space. To ensure that the respective space continues to be supplied with cooling air even if one of the two pipes breaks, the cooling-air pipe extending through the wall space and opening into the mounting space has air overflow openings in the region of the wall space.Field of SearchFor shaft sealing, packing, lubricating or bearing meansWITH PASSAGE IN BLADE, VANE, SHAFT OR ROTARY DISTRIBUTOR COMMUNICATING WITH WORKING FLUID WITH DIVERSELY ORIENTED INLET OR ADDITIONAL INLET FOR DIVERSE FLUID (E.G., HEATING, COOLING OR MIXED WORKING FLUID, ETC.)
