Description
流体の容量を制御する容量制御弁であって、
バルブハウジングと、
主弁座とソレノイドの駆動力により駆動される主弁体の主弁部との接離により制御圧の制御流体が通過するPcポートと吐出圧の吐出流体が通過するPdポートとの間を開閉する主弁と、
周囲の圧力により開放する感圧弁と、
前記感圧弁の一部を成し該感圧弁の開放により中空連通路を介して前記Pcポートと吸入圧の吸入流体が通過するPsポートとを連通させる中空管と、
前記感圧弁とは別に前記Pcポートと前記Psポートとを連通させる補助連通路が形成されており、該補助連通路は、前記主弁の閉塞後に流路断面積を広くできることを特徴としている。
この特徴によれば、容量可変型圧縮機の起動時に補助連通路の流路断面積を広くして流体を迅速に排出できるとともに、通常制御時に補助連通路の流路断面積を狭くして制御性を高めることができる。
これによれば、通常制御時にPcポートとPsポートとの流量が絞られることにより制御性が良い。
これによれば、簡単な構造により補助連通路を形成できる。
これによれば、主弁体と連通孔の協動により補助連通路の流路断面積を変更でき構造が簡単であるとともに、主弁体の移動が円滑である。
これによれば、主弁体の移動がより円滑である。
これによれば、主弁体は、係合部によって中空管に対して連通孔の閉塞方向および開放方向への移動位置が規制されるため構造が簡単である。
