Claims (5)
- コンデンサで凝縮した高圧冷媒を弁室内に導入する第1通路、前記弁室からエバポレータへ向かう冷媒が通過する第2通路及び前記エバポレータからコンプレッサへ向かう冷媒が通過する第3通路を有するブロック状の弁本体と、前記弁室内に導入される前記高圧冷媒を減圧するオリフィスと、該オリフィスに対向して配置された弁体と、該弁体を前記オリフィスに向けて付勢するばねと、前記弁体を前記オリフィスから離間する方向に移動させる作動棒と、前記エバポレータ出口側の冷媒の温度及び圧力に基づいて前記作動棒を駆動するパワーエレメントとを備えた膨張弁であって、
前記弁室を有底穴により形成するとともに該有底穴と前記第2の通路との間に薄肉の壁部を形成し、前記オリフィスが前記有底穴内に圧入された状態で前記第2の通路の出口側から前記壁部をポンチ加工することにより形成される凸部を前記オリフィスに形成された凹部に係合させて前記オリフィスを前記有底穴内に固定することを特徴とする膨張弁。 - 前記凹部は、前記オリフィスの外周に形成された凹溝であることを特徴とする請求項1に記載の膨張弁。
- 前記凹部は、前記オリフィスの外周に形成された段差部であることを特徴とする請求項1に記載の膨張弁。
- 前記有底穴内に前記作動棒を案内するガイド部材が設けられていることを特徴とする請求項1記載の膨張弁。
- 前記ガイド部材が前記オリフィスと一体的に形成されていることを特徴とする請求項4記載の膨張弁。
