ABSTRACT:
A linear compressor includes a piston that is slidably mounted in a cylinder. An hermetic spring holder has an end portion which is connected to a corresponding portion of the cylinder and which surrounds the cylinder while being located at a predetermined distance therefrom. A cap is fixedly connected to another end portion of the hermetic spring holder. A refrigerant suction guide tube is inserted from a refrigerant suction side into the piston. A spring supports the piston. The compressor causes refrigerant gas to flow solely through the refrigerant suction tube so that the internal refrigerant gas flow path of the piston is larger and the structure simpler. Thereby, damage to the path is decreased, the flow of refrigerant gas is more smooth and heat generated in the heated piston is blocked from being transferred to the refrigerant gas.
