Abstract: An injector has an orifice plate formed with plural orifices. At a radially outward position of the orifice plate is disposed a wall at least partially. It is preferable that the wall be disposed at a lower position in the direction of gravity. In the wall is formed a guide hole toward an area on the orifice plate where a strong negative pressure is developed. A portion of fuel injected from the injector adheres as adhered fuel to the orifice plate or the wall.

The adhered fuel flows from the wall onto the surface of the orifice plate and again joins a fuel jet injected from the orifices. By utilizing a negative pressure developed near the plural orifices, the adhered fuel can be recovered and again injected. Consequently, it is possible to decrease the amount of adhered fuel.
