<p>PROBLEM TO BE SOLVED: To achieve compactness and light weight of the whole body of a device by restricting the width size of a casing roughly perpendicular to an axial line of it. SOLUTION: A three-way valve 10 is provided with a valve body 14 formed as a rectangular parallelepiped and having plural ports 40a-40c provided in parallel in one narrow side surface part, a solenoid part 18 provided inside a casing 12 and including a fixed core 44, a movable core 50, and an electromagnetic coil 48, and a valve mechanism part 20 coaxially disposed with the solenoid part 18 and provided with a diaphragm 28 to be displaced under excitation action to the electromagnetic coil 48 for switching over continuity conditions of the first to the third ports 40a-40c.</p> |
