Description
流体を吐出する吐出室と流体の吐出量を制御する制御室とを連通させる吐出側通路の途中に形成された第1弁室と、流体を吸入する吸入室と前記制御室とを連通させる吸入側通路の途中に形成された第2弁室と、前記第1弁室を前記第2弁室と共に挟む位置に形成された圧力室と、を備えるバルブ本体と、
前記第1弁室にて前記吐出側通路を開閉する第1弁部と、前記第2弁室にて前記吸入側通路を開閉する第2弁部と、を一体的に有し、その往復動によりお互いに逆向きの開閉動作を行う弁体と、
前記弁体に対して前記第1弁部を閉弁させる方向に電磁駆動力を及ぼすソレノイドを備える容量制御弁であって、
前記バルブ本体には、その一端が前記圧力室に連通しその他端が前記第2弁室に臨む第1連通路の少なくとも一部が設けられていることを特徴としている。
この特徴によれば、バルブ本体は剛体であることから、第1連通路の少なくとも一部を形成する際の自由度が高く、かつ第1連通路の少なくとも一部がバルブ本体に形成されてもバルブ本体は高い強度を保持することができる。この第1連通路により、容量可変型圧縮機の起動時に、第1連通路を介して、制御室内における連続駆動時の圧力よりも高圧状態にある流体が第2弁室内に流入し、吸入室に排出される。これらのことから、高い強度を保持しつつ迅速に制御室内の圧力を連続駆動時の圧力に低下させることができる。
この特徴によれば、バルブ本体は剛体であるため、軸方向に孔を形成しても構造強度が高い。
前記圧力室は、その伸長により前記第1弁部を開弁させる方向に付勢力を及ぼすと共に周囲の圧力増加に伴って収縮する感圧体と、前記感圧体の伸縮方向の自由端に設けられて環状の座面を有するアダプタと、を備え、
前記弁体は、前記圧力室にて一体的に移動し前記第2連通路を備える第3弁部を備えており、
前記第3弁部は、前記アダプタの座面との着座及び離脱により前記吸入側通路を開閉する環状の係合面を有することを特徴としている。
この特徴によれば、圧力室の圧力増加に伴って感圧体が収縮することで第2連通路が圧力室と連通するため、第1連通路の流れと干渉し合うことなく第2連通路を介して第2弁室に流入させることができるとともに、細やかな圧力調整を行うことができる。
前記固定鉄心の前記バルブ本体の一端を閉塞する端部には、前記第2弁部が着座する座面と、径方向に貫通して形成され前記第1連通路の一部をなす貫通孔と、を備えていることを特徴としている。
この特徴によれば、固定鉄心は剛体であるため、第1連通路の一部をなす貫通孔が径方向に形成されていても構造強度が高いことから、第2弁部を安定して着座させることができる。
