Abstract
Means for driving a flow are arranged in cavities which are formed, in particular, in multishell casings of turbo engines. In one embodiment, within the cavity, ejectors are arranged which are supplied via suitable means with a propellant flow which, in turn, activates the flow, for preference a circumferential flow. Preferably, during the operation of the turbo engine a propelling fluid which is colder than the fluid content of the cavity is injected via the ejectors. In this way, at the same time, the cavity is cooled and an equalization of the temperature of the fluid content of the cavity is brought about.
