  • Patent number: 10752171
    Abstract: A cleaning device for cleaning a lens of a motor vehicle camera using a cleaning head, which includes hydraulic drive members that drive the camera or the cleaning head. The hydraulic drive members are able to generate a relative longitudinal displacement of the cleaning head with respect to the camera between a passive position in which the cleaning head is positioned outside of the image-capturing field of the camera and an active position in which the cleaning head extends facing the lens so as to allow cleaning liquid to be ejected towards the lens. The hydraulic drive members include a chamber in which a piston secured to the camera or to the cleaning head slides under the effect of the pressure of a liquid circulating between a first orifice and a second orifice which are formed respectively in the chamber.
