Thus, their very thin walled steel cylinders would become distorted to an unacceptable level. Obturator rings, made of brass, were fitted to compensate for this out-of-roundness in much the same way as a leather washer does in a bicycle pump. Wear on the rings was considerable and they only lasted a matter of hours. By the time the war ended, technology and materials had advanced sufficiently to do away with these obturator rings. 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「Obturator ring」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.
