し冷却水は流れない。The operation of the rotary solenoid valve 10 of the present embodiment configured as above will be described. When the engine (not shown) is stopped and the cooling water is below a predetermined temperature, the solenoid portion 11 is in a non-energized state, and the hole 3c of the valve 3 has a cooling water path for the first pipe 1 and the second pipe 2. And the peripheral wall 3d blocks the cooling water path, and the cooling water does not flow.

と連通状態にある。When the cooling water exceeds a predetermined temperature after the engine is started, the solenoid 11 is energized and excited,
The valve 3 is rotated clockwise, the first pipe 1 and the second pipe 2 communicate with each other through the hole 3c of the valve 3, and the cooling water flows. Even if the solenoid portion 11 is de-energized in this state, the hole 3c of the valve 3 is in communication with the cooling water passages of the first pipe 1 and the second pipe 2 due to the attractive force of the magnet 7 and the stator 8.

の洩れは発生しない。When the temperature of the cooling water falls below a predetermined temperature, the solenoid portion 11 is energized in the opposite direction and excited, and is rotated counterclockwise, and the hole 3c of the valve 3 is opened in the first pipe 1 and the second pipe. The cooling water does not flow because the peripheral wall 3d blocks the cooling water path and is orthogonal to the second cooling water path. In this state, even if the solenoid portion 11 is de-energized, the attraction force of the magnet 7 and the stator 8 causes the hole 3 of the valve 3
c is orthogonal to the cooling water passages of the first pipe 1 and the second pipe 2, and the peripheral wall 3d blocks the cooling water passage so that the cooling water does not flow. At this time, the O-ring 12 is inserted into the groove 13 of the cover 5.
Since it fits in f, the sealing property with the casing 5 is maintained and cooling water does not leak.
