Abstract: A spray tip guard for a hydraulically operated air-less spray gun which is generally Y-shaped having forwardly extending diverging ears arranged parallel to the fan spray of the spray pattern issuing from the spray tip of the spray gun. A pair of forwardly extending projections are provided at the apex of the diverging ears adjacent to and on either side of the stream of high pressure liquid emerging from the spray tip so as to provide an obstacle to the approach of the stream of high pressure liquid prior to its being atomized.

Abstract: There is provided a reversible spray tip or nozzle used with a spray gun or like device for hydraulically atomizing and spraying liquids such as paint. The spray tip includes a plastic housing having a forward extending spray tip guard integral therewith, a cylindrically shaped rotatable turret member diametrically received for rotation in the housing and having a diametric bore therethrough for receipt of a spray tip insert, and an elongated seal insert axially received in the housing upstream from the turret member. A securing nut rotatably mounted to the housing at the spray gun end thereof secures the reversible spray tip to the discharge end of the spray gun. The enhanced sealing effectiveness of the reversible spray tip permits effective sealing of the assembly by finger tightening of the securing nut.

Abstract: There is provided a high volume low pressure spray painting system, control therefor, and method of operation therefor. The high volume low pressure spray painting system includes an electrically powered blower motor with a cooling fan, an high volume low pressure blower fan driven by the blower motor, an air conduit connecting the outlet of the blower fan to a spray gun adapted to atomize liquid paint with the high volume low pressure air delivered by the blower fan, and a valve in the spray gun actuated by a trigger for controlling the high volume low pressure air delivered by the blower fan. The control for the spray painting system includes a second valve arranged downstream from the blower fan outlet biased to a normally closed position which checks the flow of high volume low pressure air delivered by the blower fan when the valve in the spray gun is closed and simultaneously with the closing of the second valve the speed of the blower motor is reduced to idle. When the valve in the spray gun is open the pressure downstream from the second valve is reduced allowing the second valve to open and causing the speed of the blower motor to increase to a normal operating speed.
