Abstract

A washer fluid pump (2) for a window cleaning system includes two ventilation openings (13, 14) arranged in a housing (5) and linked with a single opening (15) arranged on the inside. A ventilation duct (18) has two sections (16, 17) arranged tangentially to the housing (5). The ventilation openings (13, 14) are separated from each other by a partition (19). This design makes it possible for the housing (5) to have a large ventilation cross section and avoids splashed water penetrating the housing (5).
