Abstract

The invention discloses a reciprocating compressor. Since the plurality of bearing holes constituting the fluid bearing are formed to correspond to the entire area of ​​the piston, frictional loss or abrasion between the cylinder and the piston can be prevented. Since the bearing holes are formed in the lower portion of the cylinder in a concentrated manner, the piston can be stably supported. Since the compression coil spring is configured as a resonant spring, the cylinder and the piston can be easily aligned with each other in a concentric manner, and the performance of the reciprocating compressor can be improved. Since a plurality of vent holes are radially formed on the piston, the pressure of the bearing space can be reduced, whereby refrigerant can be smoothly introduced into the bearing space through the air pockets. Since the housing has a double structure consisting of an outer shell and an inner shell, the vibration energy generated by the reciprocating compressor is weakened by the friction generated between the outer shell and the inner shell. Since the casing has a double structure of an outer casing and an inner casing, vibration noise generated by 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...
