摘要： A linear compressor includes a cylinder that defines a compression chamber configured to accommodate refrigerant and that includes a cylinder nozzle configured to receive refrigerant, and a piston provided in the cylinder and configured to be pressed by refrigerant in the cylinder. The piston includes a piston body configured to move forward and backward within the cylinder, a piston front part located on a front surface of the piston body, the piston front part comprising a suction port through which refrigerant is supplied into the compression chamber, and a refrigerant collection part that is recessed from an outer circumferential surface of the piston front part, that extends to a front surface of the piston front part, and that is configured to receive at least a portion of refrigerant compressed in the compression chamber.
