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,
a supply port that passes through the cylinder in a radial direction of the cylinder and is in fluid communication with the gas inlet, and
a recess that is in fluid communication with the supply port and defined at an inner circumferential surface of the cylinder, and
wherein an axial cross section of the recess defines a first acute angle with respect to the axial direction and a second acute angle with respect to the radial direction, the second acute angle being defined between (i) a surface of the recess connected to the supply port and (ii) a straight reference line extending from the supply port in the radial direction.
