いる場合は電子機器へ電流が流れないため、電磁石へも
電流は流れず、電磁石は電磁力を発生しないため、弁は
スプリング力により閉じた状態に保たれる。In the above invention (1), when the electronic device is stopped, no current flows to the electronic device, so that no current flows to the electromagnet and the electromagnet does not generate electromagnetic force. It is kept closed.
