AIR AND FLUID CLEANING SYSTEM AND METHOD FOR CLEANING VEHICLE VISION DEVICES

摘要

According to the invention an air and fluid cleaning system for propelling a cleaning fluid and air onto a vehicle vision device such as a vehicle camera system is provided. The cleaning system comprises at least one fluid nozzle (3) aiming at the camera, at least one cleaning fluid pump (8) fluidly connected to a fluid supply conduit and to a cleaning fluid source, at least one air nozzle (4) aiming at the vehicle camera, at least one telescopic air jet (12) fluidly connected to the air nozzle, the telescopic air jet being hydraulically connected to the fluid supply conduit and the telescopic air jet (12) being operated by the fluid pressure provided by the cleaning fluid pump (8) such that during a first operation time interval of the cleaning system only cleaning fluid is propelled onto the vehicle camera and that during a second operation time interval of the cleaning system only an air jet burst is propelled onto the vehicle camera. The invention furthermore includes a method for cleaning a vehicle camera exposed to ambient.
