Abstract: An aspect of the invention refers to a system for cleaning an external vehicle-mounted sensor surface. The system comprises an air nozzle arranged to discharge air onto a sensor surface; an air pump comprising a fluid inlet, an air outlet, an air-fluid interface and a variable volume compression chamber communicated with the air outlet; an air flow control device communicated with the air nozzle and the air outlet for controlling the flow of air therethrough; and a liquid pump communicated with the fluid inlet to supply a flow of pressurized liquid such that the volume of the compression chamber varies to generate a volume of pressurized air with an absolute pressure below 10 bar.

Abstract: The present invention refers a system and a method for automatically cleaning an optic lens mounted on a vehicle, by spraying a washing liquid to remove any type of dirt from the lens such as a clear image or optic signal can be captured anytime, where an air pump is provided including a variable volume compression chamber to pressurize a volume of air, and a washing liquid conduit is communicated with a liquid nozzle and with the air pump, such as the air pump can be operated by the flow of pressurized washing liquid, such as the same flow of pressurized washing liquid is used to clean the optic surface, and to operate the air pump and generate a blast of air to blow off any liquid drop from the optic lens.

Abstract: A cleaning device for cleaning a vehicle-mounted optic surface, including a housing, the housing including an opening adapted to fit an optic surface, a fluid inlet arranged to take in washer fluid, an at least one fluid discharge port arranged to discharge washer fluid onto the optic surface, a first passage in fluidic communication with the fluid inlet and the at least one fluid discharge port so as to guide the washer fluid from the fluid inlet towards the at least one fluid discharge port and a protruding part that substantially surrounds the opening so as to define an inner wall. A cleaning system and a vehicle-mounted sensor can include an optic surface and the cleaning device.
