Benefits of technology

[0008] The present invention has been made in view of the above and other problems, and an aspect of the present invention is to provide a multi-cylinder rotary type compressor, designed to reduce intake loss in respective compressing compartments without increasing cross-sectional areas of intake ports of the respective compressing compartments.
[0009] It is another aspect of the present invention to provide a multi-cylinder rotary type compressor, designed to reduce intake noise of the compressor.

Problems solved by technology

Generally, as for rotary type compressors comprising only one compressing compartment, since a ring piston inside the compressing compartment is rotated in a state of being eccentric against the center of a rotational shaft, there occurs a problem of severe vibration caused by severe variation in rotational torque and disequilibrium of mass during compression of gas.
Accordingly, since the multi-cylinder rotary type compressor has a large resistance against the intake flow due to a small cross-sectional area of each intake port, it has a problem of enlarged intake loss and intake noise due to insufficient intake amount of gas through the respective intake ports when intake volumes of the respective compressing compartments are rapidly increased (that is, when intake amounts of the gas are rapidly increased).

Abstract

A multi-cylinder rotary type compressor designed to reduce intake loss and noise. The multi-cylinder compressor includes first and second compressing compartments partitioned from each other; first and second intake ports communicated with the first and second compressing compartments, respectively; and a communication hole located adjacent to the first and second intake ports to communicate the first compressing compartment with the second compressing compartment.

Description

CROSS-REFERENCE TO RELATED APPLICATION [0001] This application claims priority from Korean Patent Application No. 2004-73807, filed on Sep. 15, 2004 in the Korean Intellectual Property Office, the disclosure of which is incorporated herein by reference. BACKGROUND OF THE INVENTION [0002] 1. Field of the Invention [0003] The present invention relates to a multi-cylinder rotary type compressor and, more particularly, to a multi-cylinder rotary type compressor, designed to reduce intake loss and noise caused by intake of a refrigerant. [0004] 2. Description of the Related Art [0005] Generally, as for rotary type compressors comprising only one compressing compartment, since a ring piston inside the compressing compartment is rotated in a state of being eccentric against the center of a rotational shaft, there occurs a problem of severe vibration caused by severe variation in rotational torque and disequilibrium of mass during compression of gas. Accordingly, in order to solve the probl...
