  • Control valve for a refrigerant compressor and refrigerant compressor
    Patent number: 7950242
    Abstract: A refrigerant compressor has a control valve for controlling the degree of conveyance of the refrigerant compressor by setting a drive housing pressure pC of the refrigerant compressor. A control body controls a conveying-side control line between a discharge chamber, acted upon by high pressure of the compressor, and the drive housing of the compressor, and also controls a suction-side control line between the drive housing and a suction chamber, acted upon by suction pressure of the compressor variably in a throttling and/or shutting-off manner. The control body is driven electromagnetically. To improve the refrigerating capacity and the control behavior of the refrigerating system, the control body, which can shut off both the conveying-side and the suction-side control line, is also driven by means of a pressure cell.
