ABSTRACT:
A damper is configured for a vacuum pump that evacuates a vacuum system via gas transfer by a gas transfer mechanism in the vacuum pump by the rotating action of a rotating body in the vacuum pump. The damper restrains the propagation of vibrations produced in the vacuum pump to the vacuum system during an evacuation operation. The damper comprises a vibration absorbing device that is positionable between the vacuum pump and the vacuum system during an evacuation operation and that has a damping characteristic in a frequency band that coincides substantially with a rotation frequency of the rotating body of the vacuum pump.
