翻訳と辞書　辞書検索 [ 開発暫定版 ] スポンサード リンク Manifold (scuba) ： ウィキペディア英語版 Manifold (scuba) In scuba diving a manifold is used to connect two diving cylinders (tanks) containing breathing gas, providing a greater amount of gas for longer dive times or deeper dives. An isolation manifold allows the connection between the cylinders to be closed in the case of a leak from one of the cylinders or its valve or regulator, conserving the gas in the other cylinder. Diving with two or more cylinders is often associated with technical diving. ==Function== Longer and deeper dives require a greater amount of breathing gas, in turn requiring higher filling pressure, a larger cylinder or multiple cylinders. A large diameter cylinder tends to move the diver's center of mass further from the centreline, making them unbalanced in the water, and a higher pressure cylinder has a similar effect, also reducing the buoyancy of the diver, due to the thicker metal required for strength.〔 Cylinder length is also limited by ergonomic considerations in proportion to the height of the diver. A single cylinder also presents a critical single point of failure for the breathing gas supply. Multiple-tank configurations include downstream manifolded twins, with a single regulator, ''independent'' or ''separate doubles'' which are two cylinders clamped to a backplate, but without a manifold, side mount cylinders, or manifolded twins, with two complete regulator sets. The function of a manifold is to connect the gas supplies of two back mounted cylinders (called ''doubles'' or ''twins''), allowing the diver to breathe simultaneously from both. The manifold is a metal tube which is connected to the cylinder valves, and may include an isolation valve or an outlet to connect a scuba regulator.〔 On an isolation manifold the left and right cylinder valves allow the corresponding first stage regulator to be shut off, leaving the entire gas supply to be used through the remaining regulator. The central valve, called the ''isolating valve'', separates the tanks into two independent systems, each with its own first-stage and second-stage regulators, which can prevent a failure in one half of the system from losing the entire gas supply.〔 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「Manifold (scuba)」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.
