Abstract: A hermetic compressor including a compression unit for compressing a refrigerant is disclosed. The compressor includes motor for providing a compression driving force of the refrigerant, a frame on which the compression unit and the motor are installed, a rotation shaft for transferring the driving force of the motor to the compression unit, and a journal bearing disposed on the frame such that the rotation shaft passes therethrough to rotatably support the rotation shaft. The motor includes a stator fixed to an outside of the journal bearing and including a stator core, and a rotor including a body disposed outside the stator and rotatably installed such that the rotor rotates together with the rotation shaft by electromagnetic interaction with the stator, the stator core is coupled to a fastening member to prevent the relative rotation thereof with respect to the journal bearing.

Abstract: Disclosed is a hermetic compressor.

Abstract: A reciprocating compressor comprising a main frame disposed inside a case to support an electrically-driven unit, a cylinder block connected with the main frame 100 and having a compression chamber, a cylinder head having a refrigerant discharge chamber and connected with the cylinder block to seal the compression chamber, a first chamber formed at one side of the cylinder block to be connected with the refrigerant discharge chamber, a second chamber connected with a refrigerant discharge pipe being formed at other side of the cylinder block, and a gasket disposed between the main frame and the cylinder block having a groove forming a connecting path connecting the first chamber and the second chamber. Discharge pulsation is reduced as the compressed refrigerant flows to the first chamber, the connecting path, and the second chamber before being discharged through the refrigerant discharge pipe.

Abstract: A hermetic compressor having a cylinder assembly comprising a casing into which refrigerant flows, a rotor rotatably inserted in a stator disposed inside the casing, crank shaft, connecting rod connected with the crank shaft, piston, and cylinder assembly comprising a cylinder block, a valve plate connected with one side of the cylinder block and having a suction port for sucking refrigerant into the cylinder and discharge port for discharging the compressed refrigerant from the cylinder in the cylinder block, a suction valve for selectively opening the suction port, discharge valve for selectively opening the discharge port, cylinder head having suction and discharge chambers, a refrigerant path formed at one side of the cylinder head for letting refrigerant flow into the suction chamber, and a groove removed from the refrigerant path formed on the valve plate for guiding refrigerant from inside the casing into the suction chamber.
