Abstract
A solenoid valve provided with a valve element that abuts against and separates from a valve seat to seal fuel; a movable iron core capable of being separated from the valve element; and a fixed iron core arranged opposed to the movable iron core. The solenoid valve also includes: a first spring member that energizes the valve element toward a side of the valve seat; a second spring member that energizes the movable iron core toward the fixed iron core; and a stopper part disposed on the side of the valve seat with respect to the movable iron core, and arranged with the movable iron core via a gap in a displacement direction in a valve closed state. The gap is set so the movable iron core collides with the stopper part when being displaced in the valve closing direction after the valve element is opened.
