Patent ID: 8087122

Claim:
A cleaning system for a visible surface of a vehicle having a brake system comprising at least one tank of pressurized air, comprising: at least one accumulator; a bleed valve assembly operatively connected to limit flow of fluid from the at least one tank of pressurized air of the brake system to the at least one accumulator; at least one nozzle assembly arranged to direct fluid onto the visible surface; and a control valve assembly operatively connected between the at least one accumulator and the at least one nozzle assembly; whereby operation of the control valve assembly selectively allows and prevents pressurized air within the accumulator to flow to the at least one nozzle assembly; and the bleed valve assembly allows the flow of air from the at least one tank of pressurized air of the brake system to the at least one accumulator when a pressure of the air within the at least one tank of pressurized air of the brake system is above a predetermined minimum pressure level; and prevents flow of air from the at least one tank of pressurized air of the brake system to the at least one accumulator when the pressure within the at least one tank of pressurized air of the brake system is below the predetermined minimum pressure level.
