Abstract: A linear compressor includes a shell, a frame in the shell, a cylinder defining a compression space, a piston in the cylinder, a motor assembly that drives the piston, a discharge cover unit defining a discharge space that receives refrigerant from the compression space, a discharge valve that selectively opens and closes the compression space, and a valve spring assembly that provides elastic force that causes the discharge valve to contact a front surface of the cylinder. The discharge cover unit includes a cover housing, the cover housing that couples the frame, a dividing sleeve that extends from an inside of the cover housing in a longitudinal direction of the shell and that divides the discharge space into discharge chambers, and a discharge cover that inserts into the inside of the cover housing and that contacts an end portion of the dividing sleeve.

Abstract: A linear compressor is provided that may include a shell provided with a refrigerant inlet; a cylinder provided inside of the shell to form a compression space; a piston that reciprocates inside of the cylinder to compress a refrigerant in the compression space; and a motor assembly that provides a drive force to the piston and provided with a permanent magnet. The piston may include a piston body having a cylindrical outer circumferential surface and a surface-treated area, which may be processed with a material having a predetermined hardness value, and a valve support provided at an end of the piston body and having a suctioning hole be in communication with the compression space. The valve support may form a first non-surface-treated area, which is not surface-treated.
