  • Publication number: 20230407859
    Abstract: A reciprocating compressor may include a discharge muffler that attenuates discharge noise of a discharge gas discharged after being compressed in a cylinder of a compression unit, and two or more discharge hoses coupled to the discharge muffler and that discharges the discharge gas outside of the compression unit through a discharge pipe. As the reciprocating compressor has two or more discharge hoses that connect the discharge muffler and the discharge pipe, while a rigidity is reduced by reducing an inner diameter of the discharge hose, clogging of the discharge gas during high-speed operation may be suppressed or prevented and pulsation may be effectively reduced.

  • Patent number: 11619217
    Abstract: A hermetic compressor is provided. The hermetic compressor may include a compressor body spaced apart from an inner surface of a shell and including a motor unit and a compression unit; at least one support spring provided between the shell and the compressor body and that elastically supports the compressor body with respect to the shell; at least one stopper cap fixed to the inner surface of the shell or the compressor body facing the inner surface of the shell; and a stopper bar that extends from the compressor body or the inner surface of the shell and inserted into the at least one stopper cap with a predetermined distance therebetween. By mechanically restraining vibration of the compressor body and limiting amplitude of the compressor body, vibration noise of the compressor body may be reduced and the compressor body may be suppressed from being in contact with the shell to thereby prevent damage to the compressor body.

  • Publication number: 20220049690
    Abstract: A hermetic compressor may include a plurality of springs provided between a compressor body and a shell to elastically support the compressor body and to space the compressor body apart from an inner surface of a shell. A plurality of spring caps fixed to the inner surface of the shell and the compressor body may support ends of each of the plurality of springs. Each of the plurality of springs may be inclined with respect to an axial direction. Transverse stiffness of the support springs may be increased to thereby reduce vibration noise of the compressor body and prevent the compressor body from being in contact with the shell.

  • Patent number: 10047748
    Abstract: A rotary compressor, a method of manufacturing a rotary compressor, and an apparatus for manufacturing a rotary compressor are provided. The rotary compressor may include a case having an inner space, a stator to which power may be applied, the stator being disposed in the case, and a compression mechanism disposed on or at one side of the stator to generate a compression force of a refrigerant. The compression mechanism may include a rotational shaft, a cylinder that accommodates a roller coupled to the rotational shaft, a main bearing coupled a first side of the cylinder, and a sub bearing coupled to a second side of the cylinder. The main bearing may be press-fitted and fixed to an inner surface of the case.
