PROBLEM TO BE SOLVED: To provide a safe coating apparatus which does not need high pressure equipment such as a high pressure pump although its spreading efficiency is equivalent to an airless spray method. SOLUTION: A gas/liquid mixing valve 20 is connected to a grip 3 of an airless spray gun 1. When a liquid coating is supplied from a coating supply port 24 and air is supplied from an air supply port 33, the coating is mixed with the air in a mixing passage 23, and the air-mixed coating is supplied to a coating passage 12. By operating a trigger 15, a needle valve 13 is moved to open a valve port 8, and the mist of the air-mixed coating is discharged from a discharge opening 7. The air mixed in the coating contributes to forming the mist. COPYRIGHT: (C)2004,JPO&NCIPI
