Abstract
A feed device (1) for washer fluid, wherein an electric motor (3) which is provided for driving a feed pump (4) has a housing (6) which is sealed in the upper region and an opening (11) which is arranged in the lower region level with the feed pump (4). Ventilation of the electric motor (3) takes place via this opening (11). In the event of a water level reaching the electric motor (3), for example if the motor vehicle passes through water, an air bubble is formed in the housing (6), the air bubble preventing water from penetrating into the electric motor (3).
