Claims

[Scope of Claim for Utility Model Registration] A valve that is equipped with a paint inlet through which paint flows, a paint return port that returns the paint to the primary side of the inlet, and a first flow path from the paint inlet to the paint return port. a diluent inlet into which the diluent is introduced, a mixing chamber for mixing the diluent and the paint, a second flow path from the diluent inlet to the mixing chamber, a third flow path from the mixing chamber to the paint outlet, and A fourth flow path from the paint inlet to the mixing chamber is provided in the valve body, and a fourth flow path from the paint inlet to the mixing chamber;
A first flow path from the paint inlet to the paint return port is arranged linearly on the valve body, and a paint needle valve is provided that opens and closes the fourth and first flow paths reciprocally. In addition, a needle valve for the diluent that opens and closes the second flow path is disposed in the second flow path leading from the diluent inlet to the mixing chamber, and the needle valve for the diluent is arranged to open and close the second flow path. A paint mixing valve characterized in that the needle valve is configured to open the second flow path from the diluent inlet to the mixing chamber only when the fourth flow path from the paint inlet to the mixing chamber is opened. .
