PROBLEM TO BE SOLVED: To provide a high pressure jet nozzle generating no abraded part, enabling the better convergence of flat ejection and capable of enhancing ejection pressure. SOLUTION: A supply passage becomes fine toward an oval opening part 12 and this opening part forms the inlet of an outlet passage 11 and the outlet passage is connected to the oval outlet 5 having a larger cross-sectional area positioned within the flat terminal surface 3 of a nozzle body 1 and only the side wall of the outlet passage in the major axial line of an oval is expanded in a flow direction and the side wall thereof in the minor axial line of the oval extends almost in parallel to the axial line of the supply passage. |
