1. A linear compressor comprising:
a frame comprising a body portion, a flange portion extending from a front of the body portion along a radial direction of the body portion, and a bearing communication hole that is in fluid communication with a front surface of the flange portion and an inner circumferential surface of the body portion;
a cylinder that is coupled to the body portion and that includes a gas inlet (i) passing through an inner circumferential surface and an outer circumferential surface of the cylinder and (ii) in fluid communication with the bearing communication hole;
a piston that is disposed in the cylinder and that is configured to reciprocate along an axial direction of the cylinder; and
a valve member that is press-fitted to an inner circumferential surface of the gas inlet of the cylinder and that is configured to open and close the gas inlet based on a pressure of air between the cylinder and the piston,
wherein the valve member comprises (i) a coupling portion press-fitted to the inner circumferential surface of the gas inlet, (ii) a nozzle portion disposed at a first side of the coupling portion, and (iii) an elastic portion configured to open and close the nozzle portion based on the pressure.
