Title:
COMPRESSOR
Document Type and Number:
WIPO Patent Application WO/2021/215652
Kind Code:
A1
Abstract:
A compressor according to embodiments of the present invention may include an avoidance part which is provided by denting or forming a recess on a partial area of at least one of the fixation wrap and the rotation wrap and is provided to expand a space between the fixation wrap and the rotation wrap. Therefore, the present invention can prevent contact between the fixation wrap and the rotation wrap due to thermal deformation when the compressor operates. In addition, since only a partial area of the fixation wrap and the rotation wrap is processed, the present invention can maximally prevent leakage of a refrigerant and thus can prevent reduction of the compression efficiency.
