DEVICE FOR CLEANING AN OPTICAL SENSOR OF AN OPTICAL DETECTION SYSTEM FOR A MOTOR VEHICLE

The invention relates to a cleaning device () intended for spraying at least one fluid onto a surface to be cleaned of a motor vehicle, such as an optical sensor of an optical detection system, in which a movable piston (), sliding inside a hollow body () about a stationary rod extending along a longitudinal axis (X) and carrying a cleaning fluid distribution element () at one end, allows a fluid to be conveyed towards the distribution element () via passage channels () arranged between the piston and the rod and having different axial dimensions.
