Abstract
The invention relates to a wiper motor (10), with an output shaft (11) which rotates in exclusively one direction (12) and is designed at least indirectly to move at least one wiper blade (1) between two reversal positions (A, B). According to the invention, it is provided that the wiper motor (10) has means (30) which are designed at least indirectly to activate a pump (25) for conveying a cleaning fluid in such a manner that cleaning fluid can be applied to a vehicle window (2) exclusively in front of the wiper blade (1) in the respective wiping direction.
Claims14
A wiper motor, comprising:
- an output shaft which rotates in exclusively one direction and is configured at least indirectly to move at least one wiper blade between two reversal positions;
- and
- means for activating, at least indirectly, a pump for conveying a cleaning fluid in such a manner that cleaning fluid can be applied to a vehicle window exclusively in front of the wiper blade in the respective wiping direction,
- wherein the means for activating comprises a first resistance path, a second resistance path, and an annular earth path that are formed by a single piece of resistance material and connected integrally to each other, the second resistance path being electrically connected to the annular earth path within the single piece of resistance material via the first resistance path,
- wherein the first resistance path, and the second resistance path, and the annular earth path are arranged movably relative to at least one contact of a line to form a sliding electric contact connection with the at least one contact of the line, and
- wherein the first resistance path is for identifying the two reversal positions of the wiper blade and the second resistance path is for defining an angular range for activating the pump.
A wiping apparatus for wiping a vehicle window, comprising:
- at least one wiper blade;
- at least one spray device for applying a cleaning fluid to the vehicle window;
- a pump for supplying the at least one spray device with cleaning fluid;
- and
- a wiper motor comprising:
- an output shaft which rotates in exclusively one direction and is configured at least indirectly to move at least one wiper blade between two reversal positions;
- and
- means for activating, at least indirectly, a pump for conveying a cleaning fluid in such a manner that cleaning fluid can be applied to a vehicle window exclusively in front of the wiper blade in the respective wiping direction,
- wherein the means for activating comprises a first resistance path, a second resistance path, and an annular earth path that are formed by a single piece of resistance material and connected integrally to each other, the second resistance path being electrically connected to the annular earth path within the single piece of resistance material via the first resistance path,
- wherein the first resistance path, and the second resistance path, and the annular earth path are arranged movably relative to at least one contact of a line to form a sliding electric contact connection with the at least one contact of the line, and
- wherein the first resistance path is for identifying the two reversal positions of the wiper blade and the second resistance path is for defining an angular range for activating the pump.
