Description
図1に示すように、本実施形態では、自動車や一般産業用機械等の車両の駆動源として電動モータ51を用いるものである。この電動モータ51には、燃料電池システム1で発電した電力が供給される。燃料電池システム1は、燃料電池5と、燃料電池5に空気を供給する酸素供給モジュール2と、燃料電池5に水素ガスを供給する燃料供給モジュール4とを備えている。なお、燃料電池5で発電した電力を電動モータ51に供給しながら余剰電力をバッテリに蓄電しても良く、特に限定されない。
次に、図2〜図7を用いて、本実施形態に係る流体制御弁としての空気調圧弁3の構成を説明する。以下の説明において、図2の紙面を基準とした上下方向、左右方向(側方)を用いて説明するが、空気調圧弁3の実際の取付方向とは必ずしも一致していない。
(a)(別実施形態1)
図8に示すように、軸部材33の他端部は、筒状部40aの底部40a1に向かって拡径して構成されて、凹部40a2に当接する拡径部33fと、拡径部33fの先端面を平坦にした平坦部33gと、を有している。また、表面を平坦部33gに向かって突出するように形成され、平坦部33gに当接する凸部40a3を有している。この軸部材33の他端部は旋盤加工等により形成され、凸部40a3は筒状部40aの底部40a1をプレス加工することで形成される。本実施形態でも上述と同様の作用効果が得られ、特に、軸部材33の他端部の先端を平坦部33gで構成しているので、空気調圧弁3の軸長を短くすることができる。
図9に示すように、軸部材33の他端部は、筒状部40aの底部40a1に向かって縮径した円錐状に構成される第一領域33iと、第一領域33iとの境界面Pから筒状部40aの底部40a1とは反対側に向かって縮径したテーパ状に構成される第二領域33hとを有していても良い。上述した実施形態における半球状の第二領域33bに代えて、テーパ状の第二領域33hとした点が異なっている。本実施形態でも上述と同様の作用効果が得られる。
図10に示すように、軸部材33の他端部は、筒状部40aの底部40a1に向かって拡径して構成されて、凹部40a2に当接する拡径部33jと、拡径部33jの先端面を平坦にした平坦部33kと、平坦部33kから筒状部40aの底部40a1に向かって突出する半球状部33lと、を有している。この半球状部33lは、平坦部33kの孔部33k1に嵌合されるピン状部材48の先端部で構成されている。本実施形態でも上述と同様の作用効果が得られる。なお、半球状部33lを軸部材33と一体形成しても良い。
