Abstract
Die Erfindung betrifft eine Vakuumpumpe zur Erzeugung von Grob- oder Feinvakuum mit einem Gehäuse, welches Gaseinlass und Gasauslass aufweist, einem Motor und einem Lüfter. Um die Kühlung der Vakuumpumpe unabhängig vom Motor stellen zu können, wird vorgeschlagen, dass der Lüfter einen Lüftermotor aufweist. The invention relates to a vacuum pump for generating coarse or fine vacuum with a housing which gas inlet and gas outlet, a motor and a fan. In order to provide the cooling of the vacuum pump independently of the engine, it is proposed that the fan has a fan motor.
