The valve formed part of the Dalén light which was used in lighthouses from the 1900s through to the 1960s by which time electric lighting came to dominate. Many prominent contemporary engineers, including Thomas Edison, initially doubted that the device could work. The patent office demanded a special demonstration before approving the patent application.〔(The Sun Valve ), History from the AGA website.〕 == Design == The valve is controlled by four metal rods enclosed in a glass tube. The central rod that is blackened is surrounded by the three polished rods. As sunlight falls onto all of the rods, the absorbed heat of the sun allows the unequally expanding dark rod to cut the gas supply. After sunset, the central rod cools down, becoming the same length as the polished rods and opening the gas supply. The gas is lit by the small, always-burning pilot light. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Sun valve」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
