System for cleaning on-vehicle optical sensor and method for the same

The on-vehicle optical sensor cleaning system includes a washer pump that feeds a cleaning liquid, an air pump, a nozzle member, and a controller. The air pump includes a discharge valve and discharges air through the discharge valve. The discharge valve opens when air is compressed in the air pump. The nozzle member includes an ejection port that ejects a gas-liquid mixture toward a sensing surface of an on-vehicle optical sensor to remove foreign matter from the sensing surface. The cleaning liquid from the washer pump and the air from the air pump are mixed in the gas-liquid mixture. The controller controls the washer pump and the air pump. The controller is configured so that the gas-liquid mixture is ejected by storing the cleaning liquid in the nozzle member to cover the ejection port and then feeding the air to the nozzle member.

Washer-integrated type wiper apparatus

VEHICULAR EXTERIOR CAMERA ASSEMBLY WITH SELF CLEANING SYSTEM

A vehicular camera module includes a housing assembly that includes an inner housing element that accommodates a transparent cover element and that is pivotable relative to an outer housing element that mounts at a vehicle. A camera is accommodated by the housing assembly and mounted to the outer housing element. The camera views exterior of the vehicle via the cover element. An outer surface of the cover element is exposed exterior of the vehicle and, when the inner housing element and the cover element pivot relative to the outer housing element, a wiper of the outer housing element engages the outer surface of the cover element to remove moisture and/or debris from the outer surface of the cover element.

CLEANING DEVICE, MOTOR VEHICLE AND METHOD

A cleaning device for cleaning an outer surface of an optical instrument of a motor vehicle is provided. The cleaning device comprises a cleaning fluid supply for supplying to the outer surface, and a cover for temporarily covering at least the outer surface. The cleaning device is arranged to move the cover between a covering position and a releasing position in which the cover covers, or leaves uncovered, the outer surface, respectively. Upon moving from the covering position to the releasing position, or vice versa, the cover can be in successive intermediate positions covering a respective first portion and leaving uncovered a respective second portion of said outer surface. The cleaning device is arranged such that in at least one of the positions, the cleaning device defines a flow path between the cover and the outer surface to allow cleaning fluid to flow between them.

MICRO-SIZED STRUCTURE AND CONSTRUCTION METHOD FOR FLUIDIC OSCILLATOR WASH NOZZLE
20190061702 · 2019-02-28 ·

A micro-sized structure and construction method for a fluidic oscillator wash or spray nozzle (100 or 250) has a nozzle housing (110 or 252) enclosing an interior cavity (112 or 262) which receives an insert (114 or 254) having internal fluid passages defining first and second power nozzles (120, 122 or 280, 282). The power nozzles receive pressurized fluid (130) flowing through the interior cavity of the housing, where the fluid flows into the cavity at the bottom of the housing and flows upwardly to inlets (140, 142) for the power nozzles so that accelerating first and second fluid flows are aimed by the power nozzles toward one another in an interaction region (154 or 284) which exhausts laterally along a spray axis through a horn-shaped throat defined partly within the insert and partly within the flared spray outlet orifice (160 or 290) defined through the sidewall (162) in the housing.
