摘要： A reciprocating compressor is provided. The reciprocating compressor may include a cylinder having a compression space, a piston inserted into the cylinder to define the compression space while being reciprocated, the piston having a suction passage to communicate with the compression space, a gas bearing having at least one bearing hole that passes through the cylinder, so that a refrigerant gas may be injected between the cylinder and the piston to support the piston with respect to the cylinder, and a flow resister disposed at an outer circumferential surface of the cylinder or at one side of the cylinder to restrict a flow of the refrigerant gas flowing through or toward the at least one bearing hole.

摘要： A linear compressor includes a cylinder that defines a compressor space and that is configured to compress refrigerant in the compressor space, a piston located in the cylinder and configured to perform a reciprocating motion in an axial direction relative to the cylinder, a mover coupled to the piston and configured to transmit a driving force to the piston to cause the piston to perform the reciprocating motion, a stator that defines a cylinder space that receives the cylinder, in which the stator is configured to generate the driving force together with the mover, and a supporting unit that includes an overlap portion that covers at least a portion of the stator, that is coupled to the stator, and that contacts the stator.

摘要： A reciprocating compressor is provided. Bearing holes of a fluid bearing of the compressor may be positioned to correspond to a full reciprocating region of a piston, to reduce/eliminate frictional loss and/or abrasion between a cylinder and the piston. The bearing holes may be concentrated at certain regions of the cylinder to stably support the piston through a full reciprocating range. Compression coil springs may maintain concentric alignment of the cylinder and the piston. Gas through holes may be radially formed at the piston to lower a pressure of a bearing space and allow refrigerant to be smoothly introduced into the bearing space through a gas pocket A casing of the compressor may include an outer shell and an inner shell to attenuate vibration generated due to friction generated by operation of the reciprocating compressor.

摘要： 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.

摘要： In a linear motor and the linear compressor having the same according to the present disclosure, a plurality of magnets are coupled to a stator equipped with a winding coil, and a mover core made of magnetic material instead of a permanent magnet is provided on the mover, and by the magnetizing plurality of magnets in the same direction, the motor output can increase by increasing thrust instead of decreasing the centering force for the mover core. In addition, as it is applied to a two-pore motor, it is possible to easily control the mover core and to easily perform an assembly operation and a magnetization operation for the magnet. In addition, as the stator is made of a grain-oriented core, core loss may be reduced and the motor efficiency may be improved.
