ABSTRACT:
A pressure jet spray cleaning apparatus having a body member or structure with an elongate passageway for air having an inlet for connection to a source of air pressure and a water passageway having an inlet for connection to a source of water supply with each of the water passageway and air passageway having flow control means for selectively controlling the quantity of water and air moving therethrough. At least a portion of the passageways are arranged with the air passageway inside of and concentric with a water passageway with each having a nozzle in line with the discharge of the air nozzle and spaced from the water discharge end to form a venturi therebetween. The source of water supply may be from a utility water service preferably includes a power driven impeller booster pump with controls and a pressure switch means adjacent the pump outlet for interrupting the operation of the pump when the pressure is above a predetermined amount, a detergent supply may be connected to the water supply upstream from the pump with suitable control and check valves; also a detergent container is mounted on the body and has a discharge connected to the water passageway with a flow control means and check valve means therein to selectively control the amount of detergent applied to the water flow and to prevent reverse flow from the water passageway to the detergent container. With the alternative detergent supply water or air or combinations thereof may be selectively discharged on the surfaces to be cleaned and detergent selectively applied with the air or water and air to facilitate cleaning of such surfaces.
