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.

Abstract: Provided is a linear compressor. The linear compressor includes a cylinder disposed in a shell to define a compression space for a refrigerant, a piston installed to reciprocate in the cylinder, a motor assembly that allows the piston to move in an axial direction of the cylinder and thereby to compress the refrigerant introduced into the compression space, a nozzle which is provided in the cylinder and through which a portion of the refrigerant introduced into the compression space passes, and a cylinder filter installed in the cylinder and disposed at an inlet-side of the nozzle. At least one or more surfaces of the cylinder filter are oil-repellent coated.

Abstract: Provided is a linear compressor. The linear compressor includes a piston, a cylinder, and a bearing inflow passage. The bearing inflow passage includes a first bearing inflow passage extending inward from an outer circumferential surface of the cylinder in the radial direction and a second bearing inflow passage extending from the first bearing inflow passage to an inner circumferential surface of the cylinder. The second bearing inflow passage extends from the inner circumferential surface of the cylinder in a circumferential direction.
