ABSTRACT:
An improved flow regulating mechanism for paint spray guns includes a spray gun body, a flow regulating mechanism and a nozzle. The flow regulating mechanism is disposed in a secondary air duct of the spray gun body and comprises a regulating rod, a regulating knob, a fixed regulating ring and a movable regulating ring. The regulating rings are each provided with a central through hole and a plurality of spaced apart air vents running parallel to the through hole. The regulating rod is screwably disposed in the secondary air duct by the regulating knob. The movable regulating ring and the fixed regulating ring are disposed in the secondary air duct in sequence such that an air chamber is defined between the regulating rings. The size of the air chamber can be adjusted by the regulating rod. High-pressure air flowing via the secondary air duct of the spray gun body may be reduced in pressure and regulated to prevent sputtering of paint due to excessively high pressure.
