Zusammenfassung: | To provide a control valve which achieves weight reduction while securing stability during rotation.SOLUTION: A control valve 8 includes: a casing 21 having an outflow port from which a coolant flows; and a valve module 15 which is rotatably disposed in the casing 21. The valve module 15 includes: a valve member 18 having a cylindrical valve body 22 formed with a valve hole 47 which may communicate with the outflow port in conjunction with rotation of the valve module 15 and a drive shaft 27 which is connected with the valve body 22 and rotatably supported by a bottom wall part 32 of the casing 21; and a shaft cover 19 which is connected to the valve body 22 at a position spaced apart from the drive shaft 27 in a case axial direction and which is rotatably supported by an end part cover 26, facing the bottom wall part 32, of the casing 21.SELECTED DRAWING: Figure 4
【課題】回転時の安定性を確保しつつ、軽量化を図ることができる制御バルブを提供する。【解決手段】本発明の制御バルブ8は、冷却液が流出する流出口を有するケーシング21と、ケーシング21の内部に回転可能に配置された弁モジュール15と、を備え、弁モジュール15は、弁モジュール15の回転に伴い流出口に連通可能な弁孔47が形成された筒状の弁体22、及び弁体22に接続されるとともに、ケーシング21の底壁部32に回転可能に支持された駆動軸27を有する弁部材18と、駆動軸27に対してケース軸方向で離間した位置で弁体22に接続されるとともに、ケーシング21のうち底壁部32に対向する端部カバー26に回転可能に支持された軸カバー19と、を備えている。【選択図】図4 |
