Linear compressor

A linear compressor comprising:

• a cylinder that defines a compression space configured to receive refrigerant;
• a piston that is located in the cylinder and that is configured to move in an axial direction of the cylinder and to compress refrigerant in the cylinder;
• a discharge cover that defines a discharge space configured to receive refrigerant discharged from the compression space;
• a frame that accommodates the cylinder, that is coupled to the discharge cover at a front side of the frame, and that defines a gas passage configured to guide refrigerant toward the cylinder to form a gas bearing that reduces friction between the cylinder and the piston;
• a first blocking member that is located at an axial end of the cylinder, that is configured to restrict heat transfer to the cylinder from refrigerant discharged from the compression space, and that defines a gas hole communicating port that allows a portion of refrigerant discharged from the compression space to flow to the gas passage;
• and
• a second blocking member that is arranged outside of the first blocking member in a radial direction of the cylinder, that is located at an axial end of the frame, and that is configured to restrict heat transfer to the frame from refrigerant discharged from the compression space,
• wherein the discharge cover is configured to cover the gas hole communicating port and is coupled to the second blocking member and to the axial end of the frame.
