A pump includes a pump chamber in which a rotor with gates is supported so that it can rotate, an electric motor for driving the rotor, an outlet, and an inlet port that is fastened to a mounting plate and is in active connection with an inlet channel. The pump should be improved so that its service life and reliability are improved with minimal installation complexity in a vehicle, wherein intense cleaning of lines and devices connected on the suction side can be eliminated. This is achieved in that a filter is arranged in the area of the inlet channel between the mounting plate and the pump chamber.

Vacuum pump

A pump includes a pump chamber in which a rotor with gates is supported so that it can rotate, an electric motor for driving the rotor, a muffler that encloses a volume in the area of the pump chamber, wherein the volume is in active connection with an outlet port and a front muffler that is arranged within the muffler. To improve the service life and reliability of the pump in a vehicle with minimal installation expense, it is proposed that a filter is integrated into the front muffler.
