  • Patent number: 8858197
    Abstract: A compressor has a housing with a sensor coupling hole and a control valve coupling hole. A support plate is configured to contact with the compressor housing, the support plate having perforations. A sensor and a control valve pass through the perforations of the support plate respectively at positions corresponding to the sensor coupling hole and the control valve coupling hole. The sensor and control valve are coupled to the sensor coupling hole and the control valve coupling hole respectively. A washer is mounted on an outer peripheral surface of the sensor. The washer passes through the support plate and is inserted into the sensor coupling hole. The washer is coupled to the sensor coupling hole to fix the sensor.
