The housing has a pressurization device with a chamber (11) having an opening (12) and chamber openings (13,14) which connect the chamber with an environment, where the chamber is arranged within the housing. The chamber openings are separated from the opening (12) by a filter medium (12a) and is arranged such that the water present in the chamber discharges independently into the housing, under the influence of gravitational force. |
