ABSTRACT:
A solenoid valve incorporates a housing having an electric coil and a magnetic core built therein; a valve seat formed in the inside of the housing; a moving iron core adapted to be actuated by the electric coil and the magnetic core and having a valve member for opening/closing the valve seat; and a leaf spring fixed in the inside of the housing and adapted to warp at all times when the moving iron core acts. A flanged portion extends from the moving iron core in a direction perpendicular to the acting direction of the moving iron core and outward of the same. The flanged portion is provided with one face for causing the leaf spring to abut against the face of the moving iron core in the acting direction when the electric coil is energized.
