Abstract:
A linear compressor according to an embodiment of the present invention is characterized by comprising: a cylinder having a refrigerant compression space formed therein; a piston which is inserted into the cylinder and expands or compresses the compression space while reciprocating in the axial direction of the cylinder, the piston having a plurality of suction holes formed in a front surface thereof; a suction valve which is coupled to the front surface of the piston and selectively opens and closes the plurality of suction holes; a guide which passes through the center of the suction valve and is inserted into the piston; and a fastening member which has a body portion that is inserted into the guide and a head portion that is hooked to a front end of the guide, wherein the guide protrudes from the front surface of the piston, and when the piston reciprocates linearly, the suction valve, due to inertia, moves along the guide in the opposite direction relative to the moving direction of the piston.
