Abstract
A nozzle arm is associated with an air-operated motor arranged to move the nozzle arm in a forward and return cycle across a headlight. The motor is a reversing air motor that includes a mixing chamber for pressured air and a cleaning fluid. The mixing chamber produces a mist under pressure that cleans the headlight in an efficient manner in one cycle of the arm. The motor is controlled in its movement by a cycling valve and an air operated relay valve. The nozzles on the nozzle arm are thin openings that form a pressured fan-like cleaning pattern.
