First, a case where the inlet / outlet port 1A of the case 1 and the inlet / outlet port 8A of the cover 8 are communicated with each other to flow a fluid will be described. When the electromagnetic coil 2 is energized, the electromagnetic coil 2 excites the case 1 which also functions as a fixed iron core. As a result, the movable iron core 3 is attracted to the case 1 from the state shown in FIG. 1 and gradually rises in the case 1 together with the ring member 5, and at this time, the movable iron core 3
Is actuated by the second cam groove 5A of the ring member 5, the ball 6 and the first cam groove 4A of the guide member 4 and the mainspring 7
The flow passage 3A is made to approach the inlet / outlet port 8A of the cover 8 while rotating against the urging force of the cover 8, and the inlet / outlet port 1A of the case 1 and the inlet / outlet port 8A of the cover 8 are communicated with each other to allow the fluid to flow. . Next, the case of shutting off the flow path 3A will be described. When the energization of the electromagnetic coil 2 is stopped, the excited state of the case 1 is deenergized and the movable iron core 3 obtains the biasing force of the mainspring 7, which is different from the above case. It rotates in the opposite direction and begins to descend. When the movable iron core 3 descends and the flow path 3A reaches the seal member 9, the seal member 9
Thus, the flow path 3A is closed to block the flow of fluid between the inlet / outlet port 1A of the case 1 and the inlet / outlet port 8A of the cover 8.

Further, the second cam groove 5A of the ring member 5 paired with the first cam groove 4A of the guide member 4 is the first cam groove 4A.
Is formed on the upper surface as a groove that gradually deepens in the opposite direction (to the left), and its circumferential length is the same as the circumferential length of the first cam groove 4A. The balls 6 interposed between the cam grooves 4A and 5A, when the flow path 3A of the movable iron core 3 is blocked by the seal member 9, as shown in FIG. The guide member 4 and the ring member 5 are located at the shallowest position, and the distance between the guide member 4 and the ring member 5 is maximized.
4 is located at the open end, as shown in FIG. 4, the gap between the guide member 4 and the ring member 5 is smallest at the deepest portions of the cam grooves 4A and 5A, and the electromagnetic coil 2 3 causes the ring member 5 to rotate in the direction shown by the arrow in FIG. 3 in accordance with the rotation of the movable iron core 3 into the state shown in FIG. 4, and conversely, the electromagnetic coil 2 is de-energized. By doing so, the ring member 5 is rotated in the direction shown by the arrow in FIG. 4 in accordance with the rotation of the movable iron core 3 to be in the state shown in FIG.
