Abstract

Described herein is a vacuum pump (150), particularly for use in a motor vehicle (110), comprising an inlet side (230) for sucking in a fluid medium and an outlet side (240) for delivering the medium which is sucked into a surrounding area (280), where the outlet side (240) comprises an outlet non-return valve (260), which counteracts a return flow of the medium out of the surrounding area (280), where the outlet side (240) has a pressure equalization element (270) for equalizing a vacuum in the vacuum pump (150) with respect to the surrounding area (280), wherein the pressure equalization element (270) is set up for counteracting the entry of damaging substances out of the surrounding area (280) into the vacuum pump (150).
