PURPOSE:To reduce the size of a solenoid valve itself by opening or closing an oil passage of a valve seat directly by the end face of a plunger. CONSTITUTION:When a coil 15 is energized by lead wirings 7 from an external power source, the end 18A of a plunger 18 is attracted to the end face 10A of a valve seat 10 to close an oil passage 11. When the coil 15 is deenergized, the plunger 18 is returned by the hydraulic pressure of the passage 11, the end face 18A is isolated from the end face 10A of the seat 10, thereby opening the passage 11. Thus, the oil in the passage 11 is externally flowed out from the oil hole 22 of an end plate 23 through the slot 20, the hole 21 and the oil hole 19 of the plunger 18. |
