ABSTRACT:
Easily replaceable pressure reducers are located at the front of the spray gun behind the air and fluid nozzles. These reducers are calibrated and marked for use with a particular air/fluid nozzle combination and maintain .ltoreq.10 psig exit air pressure. If the air/fluid nozzle combination is changed, the pressure reducers matched to the new combination are installed at the same time, illustratively using a screwdriver. By designing the air/fluid nozzle combination and pressure reducer as matched sets, the spray gun can always inexpensively be kept in compliance with any requirements under which an HVLP device must operate. "Fan-" or shaping-compressed air driven from the same compressed air which supplies the nozzle air is supplied through an additional pressure reducer valve to reduce its pressure below that of the nozzle air. The fan air reducer employs a drilled orifice of a calculated diameter. The atomizing air reducer is of a needle type that utilizes a controlling outside diameter.
