1. A housing, with a venting device (10) arranged at the housing (2) which enables the supply of an ambient pressure to the interior of the housing (2),
wherein the venting device (10) is formed from a sleeve-like protective cap (11) with openings (12) at its side surface and a liquid-repellent membrane,
wherein a cavity for accommodating the membrane is formed in the interior of the venting device (10) and the membrane is arranged such that an opening in the wall of the housing (2) provided for the pressure supply is covered, and wherein an air exchange between the cavity of the venting device (10) and the environment takes place via the openings (12) at the side surface of the sleeve-like protective cap (11),
wherein the sleeve-like protective cap (11) comprises a narrow, circumferential expansion (14) in the region of its side surface, so that a defined drip edge is formed,
wherein the narrow, circumferential expansion (14) is arranged at such a distance from the housing (2) that a liquid draining off of the housing (2) cannot enter into the region of the openings (12).
