Abstract: A compressor includes a cylinder comprising a cylinder body which has a cylindrical shape and defining a compression space for refrigerant gas, a piston configured to be reciprocated in an axial direction within the cylinder body and to compress the refrigerant gas in the compression space, and a frame in which the cylinder is received, the frame defining a gas hole, one side of the gas hole communicating with outside so that the refrigerant gas is introduced, the other side of the gas hole extending up to an inner circumferential surface so as to guide the refrigerant gas.

Abstract: A compressor includes: a cylinder defining a compression space, a piston structure accommodated in the cylinder and including a mount member and a guide member, the guide member being configured to reciprocate inside the compression space of the cylinder in an axial direction to compress a refrigerant gas therein and a magnet frame configured to support a mover, the mover being coupled to the piston structure and configured to move together with the piston structure. The mount member connects the guide member to the magnet frame and the guide member is configured to be rotated with respect to the mount member.

Abstract: A compressor includes: a cylinder in which a piston is accommodated, the cylinder defining a compression space that is configured, based on the piston reciprocating in an axial direction, to compress a refrigerant gas therein, and a frame configured to accommodate the cylinder therein and defining a gas hole configured to pass the refrigerant gas therethrough. The gas hole is configured to communicate with an outside of the frame to receive the refrigerant gas and communicate with a gas pocket that is defined between an inner circumferential surface of the frame and an outer circumferential surface of the cylinder. The outer circumferential surface of the cylinder or the inner circumferential surface of the frame provides a plurality of restrictor regions partitioned by a gas supply passage, the gas supply passage defined to be recessed at the cylinder and configured to communicate with the gas hole.

Abstract: A compressor is disclosed. A compressor according to the present discloser includes a piston structure which has a guide member reciprocating inside a cylinder in an axial direction, and a magnet frame which supports a mover moving together with the piston structure, in which the piston structure includes the guide member, a mount member connected to the magnet frame, and an elastic member provided between the guide member and the mount member and capable of elastic deformation.

Abstract: Disclosed herein is a linear compressor. The linear compressor includes a piston, a cylinder, a frame, a first bearing gap formed between an inner circumferential surface of the frame and the outer circumferential surface of the cylinder, a second bearing gap formed between an inner circumferential surface of the cylinder and the outer circumferential surface of the piston, a bearing inflow passage and a bearing side passage formed in the cylinder such that fluid flows from the first bearing gap to the second bearing gap.

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.

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.
