- ハウジングの内部に装着された圧縮部の旋回部材を、駆動装置で旋回するように駆動することによって、吸入口から吸入した冷媒を圧縮して吐出口から吐出する圧縮機で、温度センサで温度を検出することにより異常を検知して圧縮機を保護する圧縮機用の保護装置において、
前記ハウジングを、少なくとも、前記圧縮部における低圧側の部分をカバーする低圧側ハウジングと、その他のハウジングとで構成し、
前記圧縮部における低圧側にある異常時発熱源から熱伝導を受ける前記低圧側ハウジングに、温度センサを設置し、
前記温度センサで、高温となる異常状態判定用の閾値以上の温度を検出したときに、前記駆動装置で前記旋回部材を旋回させる動作を停止させる手段を有し、
前記温度センサを、
前記低圧側ハウジングと前記駆動装置との間に配置したクラッチの軸受の近傍となる前記低圧側ハウジングの一部に、配置したことを特徴とする圧縮機用の保護装置。 - 前記閾値を、100℃以上に設定したことを特徴とする請求項1に記載の圧縮機用の保護装置。
