1. A linear compressor comprising:
a cylinder that defines a compression space configured to receive refrigerant; and
a piston disposed in the cylinder and configured to reciprocate relative to the cylinder along an axial direction of the cylinder,
wherein the cylinder comprises:
a gas inlet defined at an outer circumferential surface of the cylinder and configured to supply at least a portion of the refrigerant toward the piston, the gas inlet comprising a first gas inlet, and a second gas inlet that is disposed rearward relative to the first gas inlet in the axial direction of the cylinder, and
a supply port that radially passes through the cylinder and is in fluid communication with the gas inlet, the supply port comprising a first supply port in fluid communication with the first gas inlet, and a second supply port that is spaced apart from the first supply port and in communication with the second gas inlet,
wherein the linear compressor further comprises:
a first restrictor disposed in the first gas inlet and configured to restrict flow of the refrigerant through the first gas inlet, and
a second restrictor disposed in the second gas inlet and configured to restrict flow of the refrigerant passing through the second gas inlet,
wherein a first flow rate of the refrigerant passing through the first supply port is different from a second flow rate of the refrigerant passing through the second supply port, and
wherein a height of the first restrictor in a radial direction of the cylinder is less than a height of the second restrictor in the radial direction of the cylinder.
