PURPOSE:To improve the response property of the three-way solenoid valve upon switching by a method wherein communication between a pressure supplying port and an output pressure port or the communication between the output pressure port and a drain port are switched to each other. CONSTITUTION:The three-way solenoid valve 1 is equipped with a flange board 3, serving as the adaptor of a valve body, and a housing consisting of a cylindrical body 4 with bottom, which is continuous coaxially to the rear side of the flange board 3, while the pressure supplying port 5, equipped with an annular oil seal 51, is provided at the center of the flange board 3 and a signal pressure port 6 is provided near the pressure supplying port 5. The pressure supplying port 5 and the drain port 7 are provided at the center of the bottom of the cylindrical body 4 with the bottom and the communication between the pressure supplying port and the output pressure port or the communication between the output pressure port and the drain port may be switched, therefore, the run-off of the oil will never be caused and the response property for switching may be improved upon both of switching ON and OFF. |
