Linear compressor

Abstract

A linear compressor is provided that may include a casing, a frame accommodated in the casing, a cylinder that passes through a center of the frame, supported by the frame, and defining a compression space for a refrigerant, a piston inserted into the cylinder to reciprocate in an axial direction of the cylinder and having a first end that compresses the refrigerant supplied to the compression space, a suction muffler which is coupled to a second end of the piston and through which the refrigerant supplied to the compression space may flow, a spring that allows a resonant motion of the piston, a back cover including a cover body that defines a refrigerant opening at a central portion, such that a refrigerant passes therethrough, the back cover supporting the spring, and an inflow guide which is fixed to the cover body and guides the refrigerant passing through the refrigerant opening towards an inside of the suction muffler. At least a portion of the inflow guide may be inserted into the suction muffler, and a central axis thereof may be aligned with a central axis of the refrigerant opening.
