  • Compressor
    Patent number: 8007250
    Abstract: The present invention relates to a compressor, which includes a main refrigerant supply channel for supplying refrigerant by passing through the inside of a driving shaft and an auxiliary refrigerant supply channel for supplying refrigerant by passing through a suction chamber of front and rear housings and a slot of the driving shaft after passing through cylinder blocks in order to supply the refrigerant inhaled into a swash plate chamber to cylinder bores, thereby enhancing performance and lubricating ability of a driving shaft seal area since the refrigerant of the swash plate chamber can be used effectively.
    Type: Grant
    Filed: August 11, 2006
    Date of Patent: August 30, 2011
    Assignee: Halla Climate Control Corporation
    Inventors: Kweonsoo Lim, Mingyu Kim, Duckbin Yoon
  • Compressor
    Patent number: 7997880
    Abstract: The present invention relates to a compressor, which can inhale refrigerant supplied to a swash plate chamber to cylinder bores through the inside of a driving shaft so that a flow channel structure is simplified, thereby enhancing a suction volumetric efficiency by reducing a loss due to flow channel resistance and elastic resistance, and enhancing a compression efficiency by uniformly distributing refrigerant to the cylinder bores located at both sides of the swash plate chamber.
