Abstract:
One passage for swirling is formed in an orifice plate fixed on a nozzle body. Two swirl chambers in which fuel is caused to swirl so that the fuel has swirling force are provided at an end of the one passage for swirling on the downstream side of the flow direction of fuel. Therefore, the collision between the swirling flow in the swirl chamber and the fuel flowing in the passage for swirling is mitigated, and the swirling flow can be smoothly produced to promote pulverization of sprays injected from fuel injection ports.
