PROBLEM TO BE SOLVED: To provide a two-fluid nozzle in which the beating power of spray is enhanced in a broad and thin spray-pattern. SOLUTION: A closing face orthogonal to the axis of a flow path is provided at the jet tip-end in the air-liquid mixture flow path. One groove is formed in the diametric direction on the closing face. On the jet end-face on the outside of the closing face, an elliptic nozzle hole orthogonal to the groove is provided so that the minor-axis side of the jet hole and the groove on the closing face fall in the same direction. The jet hole is tapered to the inside face, and an outlet hole is provided in communication with the groove in the center of the tapered part. A nozzle tip is attached to the jet tip-end on the jet side of the nozzle body in which the air-liquid mixture flow-path is provided along the axis. The inside face of the nozzle tip serves as the closing face and the outside face thereof serves as the jet end-face. COPYRIGHT: (C)2005,JPO&NCIPI
