Turbo machine for low temperature applications

摘要

Turbo engine comprises a separating wall (11) made from insulating material arranged between a stepped housing (7) and an engine housing (8). The stepped housing is thermally separated from the machine housing. A line (15) for branching a controlled cooling stream is connected to the flow path of the cold gas. Preferred Features: A distributor (16) is connected to the line to distribute the cooling stream. Windings (4) and an annular gap (10) are impinged with partial streams between a stand (5) and a rotor (6).
