Abstract: 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.

Abstract: A linear compressor, a shell for a linear compressor, and a method for manufacturing a shell of a linear compressor are provided. The shell may have at least one portion having a multilayer plate, in which at least two plates may be stacked in a direction substantially perpendicular to an axis of a piston so as to accommodate a cylinder, the piston, which may be reciprocated within the cylinder, and a motor assembly directly connected to the piston to provide a drive force to the piston. At least one resonator may be disposed in or at at least a portion of an inner surface of the shell.

Abstract: The present disclosure relates to reciprocating compressor. The present invention can prevent friction loss or abrasion between a cylinder and a piston, which is caused when a hydraulic bearing is blocked with a foreign substance, by preventing the foreign substance mixed in refrigerant gas from flowing into the hydraulic bearing, and can improve compressor performance by preventing a specific volume in a compression space from increasing when high-temperature refrigerant gas discharged in the compression space is cooled, such that vibration noise of the compressor can be reduced since a gas guiding part offsets vibration and the noise generated when a refrigerant is discharged in the compression space. Furthermore, the number of vibrations of a mover is increased and a driving operation for removing foreign substances is carried out to increase the number of vibrations of a cylinder such that any foreign substance stuck in a gas hole can be cleaned, thereby increasing performance and reliability of the compressor.
