Washing device for underside of car - has nozzle on end of oscillating arm driven by double action servo cylinder to deliver high pressure water jet

摘要

The single, high pressure washer jet is mounted at the end of an oscillating arm (2) pivotted on a flat hosing positioned under the car. The arm is powered by a double action servo cylinder coupled to the water line, or driven by a separate servo control. The system enables fresh water to be used for each wash. Proofing agents and waxes can be added to the water, which does not require recycling. The oscillating jet reaches all corners of the underside for efficient dirt and salt removal.
