Windscreen washer with at least one wiper blade

摘要

The blade lies across the oncoming slipstream (5), which flows past the blade (1), forming behind it a low pressure region (6) which could lift the blade ad leave a dirty water film on the windscreen. This is prevented by an air guide device (13). The air guide device has an air inlet (15) outside the blade and close to a link component (11) of the washer arm (9). The air (25) flowing into the guide device is diverted to flow along the blade as a cross flow (18) into the low pressure region.
