Abstract
The invention provides an air and fluid cleaning system for propelling a cleaning fluid and air onto a vehicle vision device such as a vehicle camera system. The cleaning system comprises at least one fluid nozzle aimed at the camera; at least one cleaning fluid pump fluidly connected to both a fluid supply conduit and a cleaning fluid source; at least one air nozzle aimed at the vehicle camera; and at least one telescopic air jet fluidly connected to the air nozzle, hydraulically connected to the fluid supply conduit, and operated by the fluid pressure provided by the cleaning fluid pump; such that during a first operation time interval only cleaning fluid is propelled onto the vehicle camera and during a second operation time interval only an air jet burst is propelled onto the vehicle camera. The invention further includes a method for cleaning a vehicle camera exposed to ambient.
