PURPOSE: To reduce the fixing space and the number of parts by constructing the fuel flow-in and flow-out tube as single tube which serves as two conduits through partial recess.
CONSTITUTION: A valve body containing a movable core 201 is pressed against a valve seat 202 where a portion of adjuster 205 for adjusting the force of spring 204 to return the valve body to the position of valve seat 202 upon finish of excitation of coil 203 is plastically worked and recessed to serve as fuel flow-out path. fuel will pass through fuel path 207, filter 209 inserted into a fuel connector 208 and fuel flow-in path 211 in the adjuster 205 and fed finally to the seat section. While fuel will return through a gap of spring 204, outercircumferential paths 217, 218, 219, hole 220 and fuel path 222 to be formed with the interior of fixed core 221 and the recess of adjuster 205.
