  • Publication number: 20250237216
    Abstract: An electric compressor includes a motor configured to generate power; a compression mechanism configured to be driven by the motor and to compress a refrigerant; an inverter configured to control the motor; and a connector configured to include a terminal pin connecting the motor and the inverter, a plate supporting the terminal pin, and an insulator that insulates between the terminal pin and the plate, wherein at least a portion of the insulator is formed to be surrounded by the terminal pin, so that it is possible to suppress the increase in cost, weight, and size due to the connector.

  • Patent number: 12152576
    Abstract: A swash plate compressor including a cylinder block accommodating a piston for compressing a refrigerant, a front housing coupled to the front of the cylinder block and having a crank chamber, a rear housing having a suction chamber and a discharge chamber and coupled to the rear of the cylinder block. The swash plate compressor includes a valve assembly with a valve plate inserted into the rear housing, a gasket in the cylinder block, a suction plate between the valve plate and the cylinder block, a variable orifice module having a first orifice hole for refrigerant passing, a second orifice hole communicating with the suction chamber to discharge the refrigerant passing through the first orifice hole to the suction chamber, and an intermediate passage connecting the orifice holes, the first orifice hole having a variable reed, a degree of opening of which is varied depending on the refrigerant pressure.

  • Patent number: 10316831
    Abstract: Disclosed herein is a valve assembly for a variable swash plate compressor. Since an opening hole of a suction reed is enlarged toward a suction port of a valve plate and refrigerant is also introduced into a cylinder bore through the opening hole when the suction port is opened, performance of a compressor may be enhanced by an increase in flow rate.
