Abstract
A linear compressor is provided that may include a shell, a cylinder accommodated into the shell and defining a compression space for a refrigerant, a frame to which the cylinder may be fixed, a piston that reciprocates within the cylinder in an axial direction and compresses a refrigerant supplied to the compression space, a discharge valve that discharges the refrigerant compressed in the compression space, a discharge cover coupled to the frame and defining a discharge space in which the refrigerant discharged from the compression space by opening of the discharge valve may be collected, a valve spring that supports the discharge valve, and a support integrally formed with the valve spring by insert injection molding and coupled to the discharge cover. The valve spring may define one or more holes filled with a molding liquid used to form the support in the insert injection molding of the support.
