METHOD FOR DE-ICING A VEHICLE WINDOW
First Claim
Patent Images
1. A method for washing a window of a motor vehicle, said vehicle being equipped with a device comprising:
- at least one tank containing a de-icing fluid;
a tube system connecting the at least one tank to openings through which the fluid is sprayed onto the windscreen;
a supply pump designed to circulate the fluid in the tube system until it is ejected via the aforesaid openings; and
at least one wiper blade suitable for moving over the window between a low point and a high point through the action of a rotary-drive motor, the method comprising;
a) a division of the angular sector swept by said at least one blade into elementary sectors, andb) over at least one of said elementary sectors, a modulation of the exit pressure from the supply pump between a “
nominal”
pressure and a non-zero reduced pressure that is less than this nominal pressure.

Abstract
Method for washing a window of a motor vehicle, using a device comprising:
- at least one tank containing a de-icing fluid,
- a tube system connecting the at least one tank to openings through which the fluid is sprayed onto the window,
- a supply pump designed to circulate the fluid in the tube system until it is ejected via the aforesaid openings, and
- at least one wiper blade suitable for moving over the window through the action of a drive motor,
characterized in that it comprises: - a) a division of the angular sector swept by said at least one blade into elementary sectors, and
- b) over at least one elementary sector, a modulation of the exit pressure from the supply pump between a “nominal” pressure and a non-zero pressure that is less than this nominal pressure.
