Abstract

In a linear compressor including a cylinder having a compression chamber, a piston compressing a gas by a straight reciprocation in the cylinder, and a cylinder head cover covering the compression chamber of the cylinder, and having a discharge valve system and a spring for tightly supporting the discharge valve system toward an end portion of the cylinder, the discharge valve system for a linear compressor capable of minimizing re-expansion resulting from over-compression by smoothly discharging a compressed gas in the compression chamber of the cylinder, simplifying an assembly process and cutting production costs by decreasing a number of components, includes: a valve formed in a disc shape including a plurality of paths of a certain width and depth inwardly from the circumferential surface of the head, a gas discharged from the compression chamber of the cylinder passing through the paths, a diameter of the valve being set similarly to an inside diameter of the cylinder head cover.
