摘要： PROBLEM TO BE SOLVED: To provide a solenoid-driven valve capable of improving silence.
SOLUTION: This solenoid-driven valve has a disk 21 for driving the valve and an electromagnet 51m. The disk 21 includes a first portion 26 and second portions 27, 28. The electromagnet 51m is arranged so as to oppose to the disk 21 and includes a core part 52 attracting the disk 21. The electromagnet 51m forms a magnetic flux flow passing through the core part 52 and the disk 21 and applies electromagnetic force to the disk 21. On the disk 21, notches are formed such that magnetic circuit areas in the second portions 27, 28 become smaller than that in the first potion 26. Assuming that the disk 21 has no notch formed thereon, the magnetic flux flow formed on the disk 21 has relatively large magnetic flux density in the first portion 26 and relatively small magnetic flux density in the second portions 27, 28.
