Abstract
【解決手段】制御弁1は、ソレノイド10によって高圧側弁体7aが一方側に配置されるほど高圧弁部7の連通開度が拡がるとともに、当該高圧側弁体7aに作用する吐出流路4側の圧力が減殺されるように構成され、ソレノイド10によって低圧側弁体9aが他方側に配置されるほど低圧弁部9の連通開度が拡がるように構成され、ソレノイド10によって低圧側弁体9aが他方側に配置されたときに高圧側弁体7aと低圧側弁体9aとが分離するように構成される。

前記高圧弁部(7)の高圧側弁体(7a)および前記低圧弁部(9)の低圧側弁体(9a)の進退位置を制御する位置制御手段(10)を備え、
前記位置制御手段(10)によって前記高圧側弁体(7a)が一方側に配置されるほど高圧弁部(7)の連通開度が拡がるとともに、当該高圧側弁体(7a)に作用する吐出流路(4)側の圧力が減殺されるように構成され、
前記位置制御手段(10)によって前記低圧側弁体(9a)が他方側に配置されるほど低圧弁部(9)の連通開度が拡がるように構成され、
前記位置制御手段(10)によって前記低圧側弁体(9a)が前記他方側に配置されたときに前記高圧側弁体(7a)と低圧側弁体(9a)とが分離するように構成されたことを特徴とする可変容量コンプレッサの制御弁。 - 前記低圧弁部(9)は、前記位置制御手段(10)によって高圧側弁体(7a)および低圧側弁体(9a)が一方側に配置されたときに、全閉するように構成されたことを特徴とする請求項1に記載の可変容量コンプレッサの制御弁。
- 前記高圧側弁体(7a)および低圧側弁体(9a)のうち低圧側弁体(9a)のみを他方側に付勢する付勢手段(16)を備えることを特徴とする請求項1または2に記載の可変容量コンプレッサの制御弁。
