Zusammenfassung:PROBLEM TO BE SOLVED: To provide a valve having a diaphragm of which releasing force is assisted.SOLUTION: A diaphragm 100 is a diaphragm assembly comprising a dome-shaped diaphragm 102 having a surface 102a contacted with a valve seat for closing a valve and a bias member 104. The bias member 104 may be applicable as the dome-shaped diaphragm. The diaphragm 102 has a central part 106 to which the bias member 104 is attached by welding, for example. The diaphragm 102 and the bias member 104 can be fitted well to each other and each of them may be circle in shape and may include a dome-shaped portion. Preferably, an inner side of a central portion 106 of the diaphragm 102 near the top point or a geometrical center of the diaphragm 102 is welded.SELECTED DRAWING: Figure 3 【課題】開放力が補助されたダイヤフラムを有するバルブを提供する。【解決手段】ダイヤフラム100は、バルブを閉鎖するためにバルブシートと接触する表面102aを有するドーム形ダイヤフラム102と、バイアス部材104とのダイヤフラムアセンブリであり、バイアス部材104も、ドーム形ダイヤフラムであり得る。ダイヤフラム102は、例えば溶接によって、バイアス部材104が取り付けられた中央部分106を有する。ダイヤフラム102およびバイアス部材104は、相互にぴったりはめられ得、それぞれは、円形であり得、ドーム形部分を含み得る。好ましくは、ダイヤフラム102の頂点または幾何学的中心の付近のダイヤフラム102の中央部分106内が溶接される。【選択図】図3
