A linear compressor includes a hole that is defined in a discharge cover, and is configured such that a portion of a refrigerant discharged through an opened discharge valve is guided to flow to the hole. Accordingly, a discharge passage for the refrigerant used as a gas bearing may be easily defined.

Linear compressor

A linear compressor is provided that may include a casing, a compressor body accommodated in the casing and defining a compression space for a refrigerant, a suction pipe coupled to a first side of the casing to supply the refrigerant to the compression space, a discharge pipe coupled to a second side of the casing to discharge the refrigerant compressed in the compression space outside of the casing, a process pipe coupled to the second side of the casing spaced apart from the discharge pipe to inject a refrigerant for supplement into the casing, and a separator that separates a mixed fluid of a refrigerant and oil injected through the process pipe.

A linear compressor is provided. The linear compressor may include a frame coupled to a cylinder, a gas hole defined in the frame, and a gas pocket that communicates with the gas hole and transfers a refrigerant gas to the cylinder.

A linear compressor is provided. The linear compressor may include a cylinder; a frame coupled to an outer side of the cylinder; a cylinder groove defined on an outer circumferential surface of the cylinder; and a sealing member provided in the cylinder groove. The sealing member may be provided between the outer circumferential surface of the cylinder and an inner circumferential surface of the frame.

A linear compressor and a refrigerator including a linear compressor are provided. The linear compressor may include a shell coupled to a suction inlet, through which a refrigerant may be introduced, and a discharge outlet, through which the refrigerant may be discharged, a cylinder disposed within the shell to accommodate a piston reciprocated to compress the refrigerant introduced through the suction inlet, a frame that accommodates the cylinder, the frame being mounted inside the shell, and a discharge cover coupled to a front surface of the frame to discharge the refrigerant compressed by the piston to the discharge outlet. A front surface of the cylinder that faces the discharge cover may be spaced a predetermined distance from the discharged cover.

Linear compressor and refrigerator cycle including a linear compressor

An linear compressor and a linear motor for a linear compressor is provided. The linear compressor may include a shell, in which a suction inlet may be provided, a cylinder disposed in the shell to define a compression space for a refrigerant, a frame coupled to an outer side of the cylinder, a piston reciprocated in an axial direction within the cylinder, a stator cover coupled to the frame, and a linear motor supported by the frame and the stator cover to provide power to the piston. The stator cover may include a body, and at least one frame coupling portion coupled to the frame. The at least one frame coupling portion may extend from the body toward the frame.
