Abstract
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.
