Abstract

PURPOSE: To prevent the generation of rust and the staying of bubbles in an electromagnetic fuel injection valve by flowing fuel forcibly around a movable core and a fixed core which open and close a needle valve.
CONSTITUTION: On a suction pipe 2 with a throttle valve 7, an injection valve housing 31 is mounted. In the housing 31, a spool 33 on which an electromagnetic coil 32 is wound and a fixed core 35 in the center are arranged, and to the bottom of the housing 31, a nozzle body 50 with a slidable needle valve 44 is connected. To the top of the valve 44, a movable core 42 is fixed and the valve 44 is moved up and down by the magnetization of the fixed core 35. Fuel through a fuel passage 15 is injected from a nozzle 52 via a fuel introduction hole 53, and a part of the fuel flows to a fuel outlet 40 via the movable core 42 and the fixed core 35 and prevents the staying of fuel, etc., in the passage.
