摘要： A solenoid valve includes an inner stator and an outer stator that are part of a magnetic circuit. An armature is attracted toward the inner stator when a coil is energized. A spring biases the armature in a direction away from the inner stator. A rod is integrally formed with the armature and integrally reciprocates with the armature. A guide guides reciprocation of the rod. A valve operates by following the rod to open and close a fuel/liquid passage. The spring and sliding portions between the rod and the guide are arranged within a recess portion formed in the inner stator and arranged in parallel to each other while overlapping in the axial direction.

摘要： A first tubular portion forms a part of a fuel flow passage therein. A first joint surface is formed in one end surface of the first tubular portion. A first inner diameter enlarged portion is formed on a side opposite to the first joint surface. A second tubular portion forms a part of the fuel flow passage therein. A second joint surface is formed in one end surface of the second tubular portion and joined to the first joint surface. A second inner diameter enlarged portion is formed on a side opposite to the second joint surface. A welded portion is formed in an annular shape to extend radially inward from the radially outside of the first joint surface and the second joint surface by welding the first tubular portion and the second tubular portion.
