Problems solved by technology

Accordingly, since the multi-cylinder rotary compressor has a large resistance to the air flow sucked in due to the small cross-sectional area of ​​each suction port, there will be a problem due to when the suction volume of each compression chamber is rapidly increased (i.e., when When the suction volume of gas is rapidly increased) Insufficient gas suction volume through each suction port causes suction loss and suction noise to become larger

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

technical field [0001] The present invention relates to a multi-cylinder rotary compressor, and in particular, to a multi-cylinder rotary compressor designed to reduce suction loss and noise caused by suction of refrigerant. Background technique [0002] Generally, for a rotary compressor including only one compression chamber, since the annular piston in the compression chamber rotates in a state of eccentricity with respect to the center of the rotating shaft, serious deviations in the rotational torque and inconsistencies in mass during compression of the gas occur. problems caused by balance. Accordingly, in order to solve the problem, a multi-cylinder rotary compressor is provided, which includes separate compression chambers provided on upper and lower portions of the compressor, and annular pistons that rotate at relative positions within the respective compression chambers. , thereby minimizing the deviation of the rotational torque and the imbalance of the mass. ...
