    • PROBLEM TO BE SOLVED: To ensure to open and close a passage in an electromagnetic valve, and to cool the electromagnetic solenoid and reduce the operating noise and the size.
      SOLUTION: The electromagnetic valve has a cylindrical housing 12, an electromagnetic solenoid 14 provided coaxially in the housing, and a movable valve 16 displaced by the operation of the electromagnetic solenoid. The housing has first, second, and third openings 24, 26, 28, respectively provided on the first and second end walls and a cylindrical wall. The movable valve has a rod 42 which penetrates through a through-hole along an axial line of the electromagnetic solenoid, an armature 44 which is fixed on the rod and is attracted by the electromagnetic solenoid, and first and second valve elements 46, 48 mounted on the rod. The valve elements displace between a first position, where the first opening communicates with the third opening, when the first valve element opens the first opening, and the second valve element closes the second opening and a second position where the second opening communicates with the third opening, when the first valve element closes the first opening, and the second valve body opens the second opening.
