PROBLEM TO BE SOLVED: To perform a fast changing-over operation for flow passages.SOLUTION: Double-position three-way valves 60a and 60b comprise: a movable core 108 provided to be movable with respect to a valve body 100; a first seat setting surface 128 and a second seat setting surface 132 oppositely facing via spacing; a valve rod 134 sliding in an axial direction of the valve body 100 by the movable core 108; a ball valve 104a provided between the first seat setting surface 128 and the second seat setting surface 132 and installed to be settable at either the first seat setting surface 128 or the second seat setting surface 132 in response to a displacement of the valve rod 134; and a retainer 136 for holding the ball valve 104a while driving the ball valve 104a toward the first seat setting surface 128.
【課題】流路の切換動作を速やかに行うこと。【解決手段】二位置三方向弁60a、60bは、バルブボディ100に対して移動可能に設けられる可動コア108と、間隔をあけて対向する第1着座面128及び第2着座面132と、可動コア108によってバルブボディ100の軸方向に沿って摺動する弁ロッド134と、第1着座面128と第2着座面132との間に配置され、弁ロッド134の変位に応じて第1着座面128又は第2着座面132に着座可能に設けられるボール弁104aと、ボール弁104aを第1着座面128側に付勢しつつ、ボール弁104aを保持するリテーナ136とを備える。【選択図】図3
