Benefits of technology

[0013]Therefore, an object of the present invention is to provide a reciprocating compress

Problems solved by technology

However, the supplying of the lubricant requires an oil supply apparatus, and an oil shortage may occur depending on operation conditions, thereby degrading compressor performance.
Also, the compressor size needs to be increased because a space for receiving a certain amount of oil is required, and the installation direction of the compressor is limited because the entrance of the oil supply apparatus should always be kept immersed in oil.
In the conventional reciprocating compressor, however, in the case of forming gas flow paths with a small diameter in the cylinder, it is difficult to form the gas flow paths as fine pores, and impurities such as iron powder produced du

Embodiment Construction

[0033]Hereinafter, a reciprocating compressor according to the present invention will be described in detail with reference to an embodiment illustrated in the accompanying drawings.

[0034]As shown in FIG. 3, in the reciprocating compressor according to this embodiment, a frame 20 is installed within a sealed casing 10, a reciprocating motor 30 and a cylinder 41 are fixed to the frame 20, a piston 42 coupled to a mover 32 of the reciprocating motor 30 is inserted into the cylinder 40 to reciprocate, and resonant springs 51 and 52 for inducing a resonating motion of the piston 42 are installed at both sides of the piston 42 in the motion direction of the piston 42.

[0035]In the aforementioned reciprocating compressor according this embodiment, when power is applied to a coil 35 of the reciprocating motor 30, the mover 32 of the reciprocating motor 30 reciprocates. Then, the piston 42 coupled to the mover 32 sucks and compresses a refrigerant gas while linearly reciprocating within the ...

Abstract

A reciprocating compressor comprises a cylinder having a cylinder side gas flow path for guiding refrigerant discharged to the discharge space to an inner circumferential surface of the cylinder and a piston having a piston side gas flow path communicating with the cylinder side gas flow path to distribute and supply the refrigerant guided through the cylinder side gas flow path between the cylinder and the piston. Also, an outlet of the gas flow path is formed in the piston and an inlet of the gas flow path is formed in the cylinder.

Description

CROSS-REFERENCE TO RELATED APPLICATION[0001]The present disclosure relates to subject matter contained in priority Korean Application No. 10-2011-0090322, filed on Sep. 6, 2011, which is herein expressly incorporated by reference in its entirety.BACKGROUND OF THE INVENTION[0002]1. Field of the Invention[0003]The present disclosure relates to a reciprocating compressor, and more particularly, to a reciprocating compressor with a gas bearing.[0004]2. Background of the Invention[0005]Generally, a reciprocating compressor serves to intake, compress, and discharge a refrigerant as a piston linearly reciprocates within a cylinder. The reciprocating compressor may be classified into a connection type reciprocating compressor or a vibration type reciprocating compressor according to the method employed to drive the piston.[0006]In the connection type reciprocating compressor, the piston is connected to a rotating shaft associated with a rotation motor by a connection rod, which causes the p...
