FLOW PASSAGE SELECTOR VALVE

To obtain a flow passage selector valve comprising a simple structure, and having a quick and sure flow passage changeover function.SOLUTION: A flow passage selector valve B comprises: a case C; a fluid supply part 1 for supplying a fluid W to an internal space of the case C; a valve body V1 having a first circulation part R1 for making the fluid W flow to a specified circulation destination, and a first opposing face F1 at which the first circulation part R1 is opened; a second opposing face F2 of the case C opposing to the first opposing face F1; an energization member P1 for pressing the first opposing face F1 to the second opposing face F2; a drive part K for rotationally driving the valve body V1; and a plurality of second circulation parts arranged at the second opposing face F2. A fluid supply part 1 includes: a recess 4 which is opened at a space on a side opposite to the first opposing face F1 with respect to the valve body V1 out of the internal space, and in which the first circulation part R1 is opened at the second opposing face F2 in a part of the first opposing face F1 to oppose to the second circulation part; and a communication part 5 formed at a part of the recess 4 in a view orthogonal to the first opposing face F1, and making the recess 4 and the internal space communicate with each other.SELECTED DRAWING: Figure 1 【課題】簡便な構造を備え迅速かつ確実な流路切替機能をもつ流路切替バルブを得る。【解決手段】ケースＣと、ケースＣの内部空間に流体Ｗを供給する流体供給部１と、流体Ｗを特定の流通先に流通させる第１流通部Ｒ１および第１流通部Ｒ１が開口する第１対向面Ｆ１を有する弁体Ｖ１と、第１対向面Ｆ１に対向するケースＣの第２対向面Ｆ２と、第１対向面Ｆ１を第２対向面Ｆ２に押し付ける付勢部材Ｐ１と、弁体Ｖ１を回転駆動する駆動部Ｋと、第２対向面Ｆ２に設けられた複数の第２流通部と、を備え、流体供給部１が、内部空間のうち弁体Ｖ１に対して第１対向面Ｆ１の反対側の空間に開口し、第１流通部Ｒ１が、第１対向面Ｆ１の一部において第２対向面Ｆ２に開口し、第２流通部と対向する凹部４と、第１対向面Ｆ１への直交視において凹部４の一部に形成され凹部４と内部空間とを連通する連通部５と、を備えた流路切替バルブＢ。【選択図】図１
