PROBLEM TO BE SOLVED: To provide a solenoid valve which is structured to inexpensively manufacture two kinds of solenoid valves brought into an open state when a solenoid is operated, and brought into a closed state when the solenoid is operated, in the solenoid valve being utilized for industrial vehicles or construction machines and functioning as an unloading valve.SOLUTION: A first valve element 20 is formed to dispose both first openings 25a and 25b for opening and first openings 26a and 26b for opening in the vicinity of a second valve element 30. In the case where the first openings 25a and 25b for opening are disposed near the second valve element, when electrifying a coil 69, a state where an oil does not flow from an upstream oil passage to a downstream oil passage is changed into a state where the oil flows. In the case where the first openings 26a and 26b for opening are disposed near the second valve element, the state where the oil flows from the upstream oil passage to the downstream oil passage is changed into the state where the oil does not flow. Therefore, two kinds of solenoid valves can be provided without replacing the first valve element 20 or other components with any other components. |
