Abstract: Filling level indicators for washer fluid containers in motor vehicles have hitherto been arranged directly on the washer fluid container or been integrated in the instrument cluster on the motor vehicle. Despite the available information, the filling of the container when the level is too low is often delayed. A filling level indicator more effectively indicates the filling level by arranging the filling level indicator in the region of the tank filler neck, whereby the filling level in the washer fluid container is only indicated to the driver when he has in any case interrupted his journey in order to fill up with fuel and is free from other activities, so that it is virtually impossible for him to be distracted.

Abstract: A compact hydraulic supply unit has a housing forming a reservoir for a pressure fluid, and includes a housing bottom, a housing cover and a housing middle part therebetween in the form of a profiled tube. An electric motor has a laminated stator core held by the housing middle part, and drives a pump located at the housing bottom. The housing middle part has axially extending internal holding Webs for holding the laminated stator core. The size of the housing middle part is independent of the size of the electric motor, so that, with a low structural height, the housing can be so formed that it accepts a larger volume of pressure fluid.
