うに設定したことを特徴とする三方向サーボ弁。 A spool that slides via an electromagnetic drive is provided,
In a three-way servo valve that selectively connects a fluid control port to a high pressure port and a tank port according to the displacement of the spool, the high pressure fluid is divided so as to pass through two edge portions of a land formed on the spool, A fluid measuring section is configured on one side and an axial force compensating section on the other side, and a direction changing section that changes the direction of the fluid guided to the fluid measuring section multiple times is provided to reduce pressure loss between the fluid measuring section and the axial force compensating section. A three-way servo valve characterized in that the settings are approximately equal.
