    • 【課題】トルク検出を精度良く行うために、トルク変化に対する磁気検出器の出力変化を大きくすることができる磁歪式トルクセンサを提供する。【解決手段】磁気検出器18を通る磁束は、回転軸12にかかるトルクT1が零のときには一軸心CL1方向を向いている一方で、磁気検出器18は一軸心CL1に直交する磁束の径方向成分Byを検出するので、トルクT1が零のときには磁気検出器18の出力は零または略零になる。その一方で、トルクT1が印加されたときには、磁気検出器18を通る磁束は、第1磁歪部14及び第2磁歪部16の透磁率μ変化に起因した磁界の変化により、磁束の径方向成分Byを有するようになり、磁気検出器18の出力はその磁束の径方向成分Byに応じた大きさになる。従って、トルクセンサ10において、トルクT1の変化に対する磁気検出器18の出力変化を大きくすることが可能である。【選択図】図1

    • PROBLEM TO BE SOLVED: To suppress degradation of the compression efficiency during variable capacity operation in a variable capacity type scroll-type compressor.
      SOLUTION: A bypass port 22g for communicating only one compression chamber Vb out of a pair of compression chambers Va, Vb for engaging and forming a fixed scroll and a turning scroll with an intake chamber 22e is formed in a fixed substrate part of the fixed scroll. Thus, during the variable capacity operation, only the refrigerant in one compression chamber Vb in the pair of compression chambers Va, Vb flows in the intake chamber 22e through the bypass port 22g. In the other compression chamber Va, the refrigerant supplied from the intake chamber 22e is compressed without flowing in the intake chamber 22e. Thus, during the variable capacity operation, the fluid in the compression process is smoothly compressed, any leakage of the refrigerant from the compression chamber can be suppressed, and the degradation of the compression efficiency during the variable capacity operation can be suppressed.
