摘要： A diaphragm 46 is sandwiched between a first body 16 and a second body 18, and comprises an outer diaphragm 50 which is made of synthetic resin and has an opening 48 formed within an effective diameter X, and an inner diaphragm 52 arranged in the opening 48. The outer and inner diaphragms 50 and 52 are hermetically sealed by a coupling member 54 made of rubber. Therefore, the diaphragm 46 reciprocates as a synthetic resin diaphragm at very low temperatures. At normal temperatures, the inner diaphragm 52 reciprocates extensively via the rubber coupling member 54 compared with the outer diaphragm 50, thereby increasing a flow rate of the fuel pump compared with a fuel pump in which a diaphragm is made only of synthetic resin. When the diaphragm 46 is replaced depending upon a desired flow rate, the second body 18 can be manufactured using one die, which is effective in reducing manufacturing costs.
摘要翻译：隔膜46夹在第一主体16和第二主体18之间，并且包括由合成树脂制成并具有形成在有效直径X内的开口48的外隔膜50和布置在开口48中的内隔膜52 外隔膜50和内隔膜52由橡胶制的连接件54密封。因此，隔膜46作为合成树脂膜在非常低的温度下往复运动。在正常温度下，与隔膜50相比，内隔膜52经由橡胶连接构件54进行广泛的往复运动，从而与仅由合成树脂制成隔膜的燃料泵相比，增加了燃料泵的流量。当根据期望的流量更换隔膜46时，可以使用一个模具来制造第二主体18，这对于降低制造成本是有效的。

摘要： A fuel pump which has excellent heat resistance and salt resistance, is low in cost and light in weight, and which is free from fuel leakage. The fuel pump has a bottom body formed of a thermosetting resin such as bakelite material which has heat resistance and strength, and a top body and a cover formed of a thermoplastic resin. The top body and the cover 16 are assembled with a seal member such as a gasket held between the top body and the cover, and the top body and the bottom body 12 are fixed together by a fixing element. Thereby, the main body portions of the fuel pump are constituted of resin.
