Spray gun with paint supply amount control

摘要

A 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.
