Summary: | PROBLEM TO BE SOLVED: To provide a control valve enabling downsizing in an axial direction.SOLUTION: In a casing 21, a bypass outflow port 55a, a warming-up outflow port 56a and an air-conditioning outflow port 66a are formed with intervals in an axial direction, which penetrate the casing 21 in a radial direction. In a valve body 22, a bypass communication port, a warming-up communication port 104 and an air-conditioning communication port 106 are formed with intervals in the axial direction, which individually communicate with a circulation passage 93 and the outflow ports 55a, 56a, 66a according to a rotation position of the valve body 22. The air-conditioning outflow port 66a is positioned between the bypass outflow port 55a and the warming-up outflow port 56a in the axial direction, and formed at a position different from those of the bypass outflow port 55a and warming-up outflow port 56a in a circumferential direction. The air-conditioning communication port 106 has an axial opening width formed so as to become narrower than an axial interval between the bypass outflow port 55a and the warming-up port 56a.SELECTED DRAWING: Figure 7
【課題】軸方向での小型化を図ることができる制御バルブを提供する。【解決手段】ケーシング21には、ケーシング21を径方向に貫通するバイパス流出口55a、暖機流出口56a及び空調流出口66aが軸方向に間隔をあけて形成され、弁体22には、弁体22の回転位置に応じて流通路93と流出口55a,56a,66aに各別に連通するバイパス連通口、暖機連通口104及び空調連通口106が軸方向に間隔をあけて形成され、空調流出口66aは、軸方向でバイパス流出口55a及び暖機流出口56aの間に位置するとともに、周方向でバイパス流出口55a及び暖機流出口56aと異なる位置に形成され、空調連通口106は、軸方向の開口幅がバイパス流出口55a及び暖機流出口56aの間における軸方向の間隔よりも狭く形成されている。【選択図】図7 |
