Abstract: A linear compressor according to the present invention introduces a direct suction system by extending a gas suction pipe to an inside of a piston of a compressor unit to thereby minimize gas suction loss of the linear compressor and also reducing manufacturing costs and includes elastic support means necessary for vertically disposing the linear compressor in order to more effectively apply the direct suction system. According to the present invention, there is provided a compressor including a predetermined-shaped hermetic vessel, a compressor unit disposed in the hermetic vessel without having mufflers, a gas suction pipe extendedly formed to an inside of a piston of the compressor unit, an oil supply means for supplying oil into a cylinder of the compressor unit and elastic support means provided at upper and lower parts of the hermetic vessel for elastically supporting the compressor unit.
