Abstract
The present invention relates to a linear compressor, and in particular, to a linear compressor which is capable of decreasing the specific volume of a sucked refrigerant gas by decreasing the amount of the refrigerant gas to be introduced into a suction opening of a hermetic vessel thereby to be sucked into a cylinder, which is to be mixed with a high temperature refrigerant gas with which the hermetic vessel is filled, and decreasing the suction loss of a refrigerant gas to thus improve the performance efficiency of the compressor and reduce noise generated during the suction of the refrigerant gas by preventing some of the refrigerant gas to be leaked out to the inner space of the cover. The linear compressor of the invention includes a hermetic vessel having a suction opening at one side, a motor and a cylinder disposed inside the hermetic vessel, a piston inserted into the cylinder having a refrigerant flow path formed inside, a cover installed inside the hermetic vessel in the state of enclosing the cylinder and the piston and having a through opening at one side, a resonance spring elastically supporting the motion of the piston, and a refrigerant suction guide and noise can…
