Abstract

A linear compressor includes: a frame comprising a body portion, a flange portion extending from a front side 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 coupled to the body portion, 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 disposed at the frame and that is configured to open and close the bearing communication hole based on a pressure of air between the cylinder and the piston.
