Abstract: A compressor includes: a cylinder in which a piston is accommodated, the cylinder defining a compression space that is configured, based on the piston reciprocating in an axial direction, to compress a refrigerant gas therein, and a frame configured to accommodate the cylinder therein and defining a gas hole configured to pass the refrigerant gas therethrough. The gas hole is configured to communicate with an outside of the frame to receive the refrigerant gas and communicate with a gas pocket that is defined between an inner circumferential surface of the frame and an outer circumferential surface of the cylinder. The outer circumferential surface of the cylinder or the inner circumferential surface of the frame provides a plurality of restrictor regions partitioned by a gas supply passage, the gas supply passage defined to be recessed at the cylinder and configured to communicate with the gas hole.
