Abstract
The detector for vacuum containers uses test gas which is fed in via leak points and a test gas detector (2) at the inlet of a turbo vacuum pump whose output is connected to a series pump (7). Gas from the vessel (9) is fed to the turbo vacuum pump (1) via a pipe (8) which protrudes into an intermediate stage of the turbo vacuum pump. The arrangement is more economical to produce than conventional arrangements since it enables the elimination of a high vacuum pump. The turbo vacuum pump has an annular channel (10) at the point at which the connecting pipe protrudes. The annular channel encloses the intermediate stage. Two disc sets with different compression characteristics may be mounted on a common shaft in the turbo vacuum pump housing. The pipe protrudes into the space between the discs.
