  • Publication number: 20100141066
    Abstract: The present invention provides an inverter connection terminal assembly for an electric compressor. The inverter connection terminal assembly includes a connection terminal, in which upper and lower terminal projections project from the upper and lower surfaces of a plate, respectively, an inverter connection cable connected to the upper terminal projection of the connection terminal, a motor connection cable connected to the lower terminal projection of the connection terminal, an upper connector for connecting the upper terminal projection and the inverter connection cable, and a lower connector for connecting the lower terminal projection and the motor connection cable, wherein the lower terminal projection of the connection terminal includes a thread formed on the surface thereof such that the motor connection cable is fixed to the lower terminal projection by fastening a nut while a washer and a ring connector are sequentially inserted into the lower terminal projection.

  • Publication number: 20100092311
    Abstract: The present invention provides a displacement control valve for a variable displacement compressor, the displacement control valve including a valve housing, in which a discharge chamber passage and a crank chamber passage are provided, and a valve body for opening and closing the valve, characterized in that a motor rotates the valve body to open and close the valve. Therefore, the present invention can reduce the overall length of the displacement control valve to reduce the size of the compressor, thereby achieving a compact structure of the compressor.
