Description
バルブ部の弁開度に応じて容量可変型圧縮機の流量又は圧力を制御する容量制御弁であって、
第1圧力の流体を通す第1連通路、前記第1連通路に隣接配置され第2圧力の流体を通す第2連通路、第3圧力の流体を通す第3連通路、及び、前記第2連通路と前記第3連通路とを連通する弁孔に配設される主弁座を有するバルブ本体と、
補助弁座を有するロッドを駆動するソレノイドと、
前記第1連通路と前記第3連通路とを連通する中間連通路、前記主弁座と離接し前記弁孔を開閉する主弁部、及び、前記補助弁座と離接して前記中間連通路を開閉する補助弁部を有する弁体と、
前記主弁部の閉弁方向に付勢する第1付勢部材と、を備え、
前記第1付勢部材のバネ定数は、前記主弁部が開弁状態で大きく、閉弁状態で小さくなる特性を有することを特徴としている。
この特徴によれば、第1付勢部材に作用する荷重が小さくなる主弁部の開弁状態では、バネ定数は大きくなるので、第1付勢部材はほとんど変形しない。このためロッドと弁体は相対位置を保った状態で一体的に変位するので、容量制御弁は安定して主弁部の開度を制御することができる。また、第1付勢部材に作用する荷重が大きくなる主弁部の閉弁状態では、第1付勢部材のバネ定数は小さくなるので、ソレノイド30の出力を過度に高めることなくロッドは第1付勢部材を容易に変形させて補助弁部を強制的に開弁できる。これにより、液冷媒排出において、補助弁部の開度を全開状態に維持して吸入室の圧力に関わらず液冷媒を効率良く排出できる。
前記第1付勢部材は前記ロッドと前記弁体との間に配設されることを特徴としている。
この特徴によれば、ロッドと弁体との間に配設される第1付勢部材を介してソレノイドの駆動力を主弁部の閉弁方向に伝達して確実に閉弁させることができる。
前記第1付勢部材は前記中間連通路を連通する連通部を有することを特徴としている。
この特徴によれば、中間連通路を流れる冷媒は連通路によって冷媒の流れが阻害されることがない。
前記ソレノイドは、前記ロッドに接続されるプランジャ、前記プランジャと前記バルブ本体の間に配置されるコア、電磁コイル、及び、前記プランジャと前記コアとの間に配設される第2付勢部材をさらに備えることを特徴としている。
この特徴によれば、プランジャとコアとの間に配設される第2付勢部材によって、弁体を主弁部の開弁方向に確実に付勢することができる。
前記第1圧力は前記容量可変型圧縮機の吸入圧力、前記第2圧力は前記容量可変型圧縮機の吐出圧力、前記第3圧力は前記容量可変型圧縮機のクランク室の圧力であり、また、
前記第1圧力は前記容量可変型圧縮機のクランク室の圧力、前記第2圧力は前記容量可変型圧縮機の吐出圧力、前記第3圧力は前記容量可変型圧縮機の吸入圧力であることを特徴としている。
この特徴によれば、様々な容量可変型圧縮機に対応することができる。
前記補助弁部が開状態のときに、前記主弁部を閉状態から開状態にすることを特徴としている。
この特徴によれば、液冷媒排出時に弁体に感圧体の付勢力が作用しない状態で主弁部を開弁させ、吐出室から制御室への流量を増加させて圧縮機の負荷を低減させることができる。
