Abstract
A pressure compensation device for a housing, in particular of a motor vehicle, having 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 by wall regions of the pressure compensation valve formed from an elastically deformable material, and having at least one protective cap.
Claims15
A pressure compensation device for a housing of a motor vehicle, comprising:
- at least one pressure compensation valve through which a gaseous medium can flow, each of the at least one pressure compensation valves comprising:
- an inner casing surface provided on an inner circumference of the at least one pressure compensation valve, the inner casing surface delimiting a volume of the at least one pressure compensation valve;
- an outer casing surface provided on an outer circumference of the at least one pressure compensation valve, the outer casing surface facing away from the inner casing surface;
- at least one pressure compensation opening, which is delimited completely by an elastically deformable material through which the gaseous medium can flow;
- and
- at least one protective cap,
- wherein the outer casing surface is surrounded completely by the at least one protective cap except for a subregion of the outer casing surface, the subregion being arranged overlapping with a through-flow opening of the at least one protective cap through which the gaseous medium can flow,
- wherein the through-flow opening has an area which lies in a range from 0.95 to 5 square millimeters, and
- wherein the at least one protective cap has at least two cap parts, which are joined via at least one hinge and are pivotable relative to one another.
