TURBINE UNIT

摘要

According to the invention, suitable means for driving a flow (18) are arranged in annular or annular-shaped cavities (2, 7), embodied, in particular, in multi-shelled (11; 12, 13) housings in turbine units. Ejectors (16, 26) are arranged within the cavity which are supplied by suitable means (14) with a flow (17) of propellant, which generates a circular or helical flow within the flow (18). The invention is particularly suitable for avoiding housing distortions when the turbine unit is idle.
