Abstract
A scroll compressor is disclosed. In the scroll compressor of this invention, the involute fixed and orbiting scroll wraps engage with each other to form a plurality of variable compression chambers between them. In the compressor, at least one of the involute fixed and orbiting scroll wraps is formed at a middle section thereof to be thicker than the other sections. Therefore, it is possible for the fixed and orbiting scroll wraps to engage with each other without forming a gap at the central portion of the compression part, thus minimizing a leakage of compressed gas refrigerant during a gas refrigerant compressing process of the scroll compressor. The scroll compressor of this invention is thus improved in its gas refrigerant compression efficiency, and is reduced in its operational noises.
