摘要

The system (10) has a pump (25) arranged close to a reservoir (11) and conveying wash liquid from the reservoir. The pump and another pump (30) are coupled with an output side (27) and an input side (29) via a connecting line (28). The pumps are designed as bi-pumps, and convey wash liquid to spraying orifices (21, 22) at longitudinal sides (17, 18) of wiper blades (12, 13) i.e. aqua-blade wiper blades, based on rotation direction. The latter pump is arranged in the blades in a region close distance to the reservoir, and the connecting line is designed as a heatable connecting line.
