Pressure compensation device for a housing, in particular of a motor vehicle, comprising:
- at least one pressure compensation valve, which has a casing surface on the inner circumference delimiting a volume of the pressure compensation valve through which a gaseous medium can flow, a casing surface on the outer circumference facing away from the casing surface on the inner circumference, and at least one pressure compensation opening, through which the medium can flow and which is delimited completely by wall regions of the pressure compensation valve formed from an elastically deformable material, and having at least one protective cap, wherein the casing surface on the outer circumference is surrounded completely by the protective cap except for a subregion of the casing surface on the outer circumference that is arranged overlapping with a through-flow opening of the protective cap through which the medium can flow and having a surface that lies in a range from 0.95 to 5 square millimeters.
