International ClassB05B 007/12Foreign Application Priority Data1989-08-11 JPAbstractA premixing-type spray gun which mixes a paint and compressed air inside the atomizing head thereof and sprays out the mixture as atomized from the spray hole, having a flow control valve to adjust the sectional area of the paint supply path communicating with the paint nozzle or having a relief valve disposed downstream of a throttle path made of the inlet path through which the spraying air pressure is partially supplied into the pressurizing container.The flow rate of the paint can be adjusted independently of the trigger operation of the spray gun, and the amount of the paint suppled under pressure can be controlled, thereby keeping a stable spray amount.Field of SearchAdjustable gas flow directing or controlling meansSerially arranged mixing zones (i.e., of same or mixed fluids) INCLUDING SUPPLEMENTAL GAS SHAPING OR SHIELDING JET Fluid pressure discharge means Flow means of one fluid surrounds the other at outlet And valving means controlling flow for combining INCLUDING SUPPLY HOLDER FOR MATERIAL Liquid inlet port to submerged gas tube Parallel pressure flows to holder and pressure reducer Branched flow from main stream to holder Unitary mounting for pressure fluid inlet and liquid outlet | |
