Problems solved by technology

[0010] A disadvantage of this embodiment is that the cleaning fluid exits at a maximum flow rate from the beginning to the end of the injection and the absence of any variation in the flow rate prevents optimization of fluid consumption

Embodiment Construction

[0054] It should be noted at the outset that although the drawings illustrate embodiments of the invention in detail, they can of course be used as appropriate to better define the invention. It will also be understood that the embodiments of the invention shown by the figures are given as non-limiting examples. Thus, other configurations of the device according to the invention can be produced, in particular by varying the arrangement, distribution and axial and / or radial dimensions of the channels, which necessarily have an effect on the cleaning fluid flow rate and the associated pressure.

[0055] Note also that in the following description the terms "upstream" and "downstream" refer to the flow direction of the cleaning fluid in the cleaning device according to the invention. Thus, the term "upstream" refers to the side of the device according to the invention via which the cleaning fluid is introduced into said device; and the term "downstream" refers to the side of the ...

Abstract

The invention relates to a cleaning device (100) for projecting at least one fluid onto a surface to be cleaned of a motor vehicle, such as an optical sensor of an optical detection system, wherein amobile piston (3) sliding in a hollow body (1) around a fixed rod extending along a longitudinal axis (X) and carrying at one end a cleaning fluid dispensing element (8, 9) enables the fluid to flow to the dispensing element (8, 9), through passage channels (12) arranged between the piston and the rod and having different axial dimensions.

Description

technical field [0001] The invention relates to the field of driver assistance devices and optical detection systems for this purpose, and more particularly to a cleaning device for spraying at least one fluid towards a surface to be cleaned belonging to a motor vehicle, such as towards an optical Optical sensor for the detection system. Background technique [0002] Any system comprising an optical sensor, such as a camera, laser sensor or other sensor, based on the emission and / or detection of light in the spectrum visible or invisible to humans, especially the infrared spectrum, is referred to as an optical detection system. [0003] Such optical detection systems are fitted to an increasing number of motor vehicles in order to assist the driver of the vehicle in certain driving situations, a well-known example being assisted parking. In order for this assistance to be as effective as possible, the data provided by the optical detection system need to be of the highest p...
