    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.

    Abstract: A linear compressor includes a hole that is defined in a discharge cover, and is configured such that a portion of a refrigerant discharged through an opened discharge valve is guided to flow to the hole. Accordingly, a discharge passage for the refrigerant used as a gas bearing may be easily defined.

    Abstract: A linear compressor according to an embodiment of the present invention comprises: a shell; a cylinder which is provided inside the shell and forms a compression space of a refrigerant; a frame which is coupled to the outer side of the cylinder; a piston which is provided so as to perform a reciprocating movement in an axial direction inside the cylinder; a motor which supplies power to the piston; and a spring mechanism which is coupled to the piston to allow the piston to perform a resonant movement, wherein the spring mechanism may comprise: a support which is connected to the piston and comprises a spring support unit having one or more insertion holes formed therein; a first coupling protrusion which extends from the rear side of the spring support unit along the edge of the insertion hole; a support cap which is inserted into the insertion hole and comprises a second coupling protrusion protruding from the front side of the spring support unit; a first resonant spring which is inserted into the outer circumferential surface of the second coupling protrusion; and a second resonant spring which is inserted into the outer circumferential surface of the first coupling protrusion.
