が終了することを特徴とする燃料噴射弁。 In an ejector type fuel injection valve that atomizes fuel oil for a diesel engine using an atomizing fluid, the valve stem 6 is composed of a large diameter portion 6a and a small diameter portion 6b and is biased in the small diameter direction, and a large diameter portion 6a. A conical valve 114 provided in the small diameter portion 6b to control the atomizing fluid, a conical valve 10 provided in the small diameter portion 6b to control the fuel, and a conical valve 114 in the large diameter portion 6a that abuts and has a smaller diameter than the conical valve. the valve seat 115,
A valve seat 11 that abuts the conical valve 10 of the small diameter portion 6b and has a larger diameter than the conical valve; a passage 111 that penetrates from the side surface of the upper end of the valve stem small diameter portion 6b to the tip of the small diameter portion; 112, a pore 113 provided at the tip of the valve stem to communicate with the passage, and a flow path provided between the pore 113 and the outlet of the conical valve 10, through which fuel and atomizing fluid mix. 12 and at least one nozzle 117 provided at the tip of the mixing flow path, and the valve stem 6 is pushed up by the pressure increase of the atomizing fluid stored in the chamber 104 to create a conical shape. Valve 1
14 is opened, the entrance of the passage 111 on the side is opened, and the atomizing fluid passes through the pores 112 and 113 and enters the flow passage 1.
At the same time, the fuel in the chamber 5 is sucked into the flow path 12, collides with the atomizing fluid, atomizes and mixes, and is injected into the engine combustion chamber through the nozzle 117, reducing the pressure of the atomizing fluid. A fuel injection valve characterized in that the control valve closes and fuel injection ends.
