The circular passage, which is a portion of the suction pressure region, has a circular cross-section, and is in communication with an external refrigerant circuit. The communication passage, which is a portion of the suction pressure region, intersects the circular passage for connection therewith, and is communicable with the compression chamber. The cylindrical member is fitted into the circular passage. The passage heat-insulating member made of an insulating material covers at least a portion of a passage wall surface which forms the communication passage. Rotation of the cylindrical member is prevented by engaging the passage heat-insulating member with the cylindrical member.

摘要： A torque limiter to be operatively coupled to an engine is secured to the outer periphery of a driving shaft through screwing-engagement. The driving shaft and the torque limiter are screw-engaged and fixed to each other so that the torque limiter is pushed or urged against a seating face formed at the outer periphery of the driving shaft. The seating face abuts against the torque limiter restricting the screwing-movement of the driving shaft. Rotation force is transmitted between the driving shaft and the torque limiter via the seating face. A cylindrical member is disposed between the torque limiter and the seating face of the driving shaft. The cylindrical member is press-fitted and fixed to the outer periphery of the driving shaft, so that the power transmission between the driving shaft and the torque limiter is also performed through the press-fit portion between the cylindrical member and the driving shaft.
