Abstract

According to a scroll compressor associated with the present disclosure, the entire cross-sectional area of bypass holes formed at a compression chamber with a larger volume reduction gradient between the both compression chambers may be formed to be larger than that of bypass holes at the other compression chamber to prevent over-compression at the compression chamber with a larger volume reduction gradient, thereby enhancing the entire efficiency of the compressor.

Description

technical field [0001] The present disclosure relates to a scroll compressor, and more particularly, to a scroll compressor formed to have different volume reduction gradients for two compression chambers. Background technique [0002] A scroll compressor is a compressor in which the orbiting scroll moves relative to the fixed scroll in a state where the fixed wrap of the fixed scroll is engaged with the orbiting wrap of the orbiting scroll. During the orbiting motion, a continuously moving compression chamber is formed between the fixed scroll and the orbiting scroll to suck and compress refrigerant. [0003] The scroll compressor continuously performs suction, compression, and discharge, and thus has superior characteristics in terms of vibration and noise generated during its operation, as compared with other types of compressors. [0004] The operating characteristics of a scroll compressor are determined by the types of its fixed and orbiting scrolls. The fixed and or...
