Abstract
An evacuable casing for a rotor machine comprises a cover surrounding the machine, bearing means mounting the cover for rotation on a foundation, the cover having an endless base edge, and sealing means extending along the base edge to seal against the foundation when a vacuum is applied within the cover. One part of the cover is mounted for movement relative to a second part of the cover to form a large opening in the cover, this opening in combination with said rotation of the cover on the foundation providing easy access to the machine from any radial direction.
