Abstract: Disclosed herein is a linear compressor wherein a compression unit, including a cylinder and a linear motor, is supported by a frame mounted in a hermetic container. The frame is die cast using diamagnetic zinc having a high forming accuracy, thereby preventing an electromagnetic force of the linear motor from being leaked therethrough, and enabling a reduction in the number of machining times thereof after die casting.

Abstract: Disclosed herein is a linear compressor. The linear compressor comprises a cooling channel disposed in contact with a bobbin on which a coil is wound, and a cooling fluid supply unit to supply a cooling fluid to the cooling channel such that the bobbin and the coil are cooled by means of the cooling fluid. Consequently, the coil is prevented from overheating, whereby compression efficiency of the linear compressor is effectively improved, and service life of the linear compressor is effectively increased.

Abstract: Disclosed herein is a linear compressor, which is designed in such a fashion that oil is suctioned into a space between a cylinder and a piston by a low pressure produced between the cylinder and the piston when the piston moves backward, and then is discharged to the outside by a high pressure produced between the cylinder and the piston when the piston moves forward, resulting in a simplified oil pumping structure and low cost.

Abstract: Disclosed herein is linear compressor. The linear compressor comprises a cylinder, a piston disposed to linearly reciprocate into the cylinder, and a linear motor provided to linearly reciprocate the piston. The linear motor includes an outer core, a bobbin mounted in the outer core, a coil wound on the bobbin, an inner core spaced apart from the outer core to define a gap therebetween, the inner core being mounted to linearly reciprocate simultaneously with the piston, a magnet holder mounted on the inner core, and a magnet mounted in the magnet holder. The linear compressor has a simplified structure, resulting in a reduced number of parts and low manufacturing costs.

Abstract: A reciprocating compressor includes a reciprocating motor that generates a reciprocation force and a compressing unit to which a discharge pipe that discharges a compressed fluid is connected. The compressing unit compresses a fluid by receiving the reciprocation force generated by the reciprocating motor. A frame, to which the reciprocating motor and the compressing unit are fixed, is connected to a suction pipe that sucks a fluid to be compressed at one side thereof, and that contains lubricating oil therein.
