Abstract
A washer fluid pump (2) for a windshield washer system (3) of a motor vehicle has ventilation ducts (25, 25′) which are arranged in a housing (17) parallel to the longitudinal axis. The ventilation ducts (25, 25′) open out behind bulkheads (21, 22) which are likewise arranged parallel to the longitudinal axis. The bulkheads (21, 22) bridge a constriction (20), which is arranged between an electric motor (15) and a pump stage (16), of the housing (17). In this way, the electric motor (15) is reliably protected against spray water. The washer fluid pump (2) can also be produced in a particularly cost-effective manner.
