Description
吐出圧力の吐出流体が通過する吐出ポート、吸入圧力の吸入流体が通過する吸入ポートおよび制御圧力の制御流体が通過する制御ポートが形成されたバルブハウジングと、
ソレノイドにより駆動されるロッドと、
CS弁座とCS弁体とにより構成され前記制御ポートと前記吸入ポートとの連通を開閉するCS弁と、
DC弁座とDC弁体とにより構成され、前記CS弁体に対して相対移動可能に配置され、前記ロッドの移動により前記吐出ポートと前記制御ポートとの連通を開閉するDC弁と、
前記CS弁体と連動可能に連結され、前記バルブハウジングに形成され吸入流体が供給される吸入流体供給室に配置され吸入圧力により動作する圧力駆動部とを備え、
前記ロッドの移動により前記CS弁の閉塞状態を維持したまま前記CS弁体と前記DC弁体とが共に移動し、前記ロッドがさらに移動すると前記DC弁の閉塞状態を維持したまま前記DC弁体を残して前記CS弁体が単独で移動する。
これによれば、DC弁体はCS弁体に対して相対移動可能に配置されていることにより、通常制御時においてCS弁が閉塞された状態でDC弁を開閉制御することができるとともに、最大通電状態ではDC弁の閉塞状態を維持したままロッドの移動によりCS弁を開放し制御ポートと吸入ポートとを連通させることにより、制御圧力を低下させることができるため、起動時の流体排出機能に優れ、かつ高圧縮効率となる容量制御弁を提供できる。加えて、起動時や通常制御時等に、吸入流体供給室における吸入圧力が高いときには圧力駆動部を動作させてソレノイドの駆動力を補助することができるため、安定した起動時の流体排出機能と圧縮性能を有する容量制御弁を提供できる。
これによれば、DC弁体にCS弁体を挿通させることにより、DC弁を有する容量制御弁をコンパクトに構成できるとともに、非通電状態および通常制御時においてCS弁の閉塞状態を確実に維持したままDC弁体をCS弁体と共に移動させることができる。
これによれば、DC弁体の他端における内径部にCS弁座が形成され、その外径側にDC弁座が形成されることにより、CS弁およびDC弁の開閉による流路の切り換えがスムーズに行われるため、応答性が良い。
これによれば、非通電状態および通常制御時においてはDC弁体がCS弁体に対して閉鎖状態を確実に維持し、最大通電状態ではDC弁体がDC弁座に対して閉鎖状態を確実に維持できる。加えて、非通電状態および通常制御時においてDC弁体は付勢手段によりロッドの移動方向に付勢されることから、ソレノイドへの印加電流を少なくできる。
これによれば、バルブハウジングの構造を簡素にできる。
これによれば、CS弁体の構造を簡素にできる。
