<P>PROBLEM TO BE SOLVED: To provide an electromagnetic fuel injection valve configured to maintain stable valve open/closed state for a long time, to mitigate the impact when the valve is opened/closed, and to reduce wear or noise of a collision part. <P>SOLUTION: A guide bush 19 of high hardness is fixed to an inner circumference of a fixed core 6. A sliding member 20 to be slidably fitted on an inner circumferential surface of the guide bush 19 and a stopper member 22 arranged forward thereof are fixed to a stem 15b of a valve body 15. A movable core 16 is slidably fitted to the stem 15b so as to move in a limited stroke between the sliding member 20 and the stopper member 22. When a coil 37 is electrically energized, the movable core 16 to be attracted by the fixed core 6 opens the valve body 15 via the sliding member 20. When the coil 37 is not electrically energized, the valve body 15 is closed by a biasing force of a valve spring 33. The movable core 16 abuts on the stopper member 22. <P>COPYRIGHT: (C)2013,JPO&INPIT |
