Abstract

Disclosed is a reciprocating compressor. As bearing holes which constitute a fluid bearing are formed to correspond to an entire region of a piston, a frictional loss or abrasion between a cylinder and the piston can be prevented. As the bearing holes are formed at a lower part of the cylinder in a concentrated manner, the piston can be stably supported. As compression coil springs are configured as resonant springs, the cylinder and the piston can be easily aligned with each other in a concentric manner, and performance of the reciprocating compressor can be enhanced. As gas through holes are formed at the piston in a radial direction, a pressure of a bearing space can be lowered and thus a refrigerant can be smoothly introduced into the bearing space through a gas pocket. As a shell has a double structure of an outer shell and an inner shell, vibrations generated from the reciprocating compressor can be attenuated by friction occurring between the outer shell and the inner shell. As a casing has a double structure of an outer shell and an inner shell, vibration noise generated from the reciprocating compressor can be attenuated.

Description

technical field [0001] This invention relates to reciprocating compressors, and more particularly to reciprocating compressors having fluid bearings. Background technique [0002] In general, a reciprocating compressor draws in refrigerant, compresses it, and discharges it as a piston performs linear reciprocating motion within a cylinder. According to the driving method of the piston, the reciprocating compressor can be classified into a connection type and a vibration type. [0003] In the connection type reciprocating compressor, refrigerant is compressed as a piston performs reciprocating motion within a cylinder in a state where a rotating shaft of a rotary electric machine is connected to a connecting rod. On the other hand, in the vibration type reciprocating compressor, in a connected state of a mover connected to a reciprocating motor, refrigerant is compressed as a piston vibrates while performing reciprocating motion within a cylinder. The present invention rela...
