Windscreen wiper with integral washer jet - has perforated supply pipe fixed near centre of blade or between twin blades

摘要

The windscreen wiper includes a screen washer jet which consists of a perforated pipe which moves with a double wiper blade or a single one. If the blade is double, the perforated pipe (1) is placed between the two sides (2,2a). There is a connection (3) to the liquid supply pipe (4) and a support (5) which renders the whole assembly solid. The water jet always follows the position of the wiper blades and no water is wasted.
