Title:
SCROLL COMPRESSOR
Document Type and Number:
WIPO Patent Application WO/2017/188575
Kind Code:
A1
Abstract:
A scroll compressor according to the present invention comprises: an orbiting scroll having an orbiting wrap and performing an orbital movement; and a fixed scroll having a fixed wrap engaged with the orbiting wrap so as to form a compression chamber including a suction chamber, an intermediate pressure chamber, and a discharge chamber, wherein an offset section having a gap larger than the orbital radius exists between the side surface of the orbiting wrap and the side surface of the fixed wrap, which are opposite to each other, in a state where the center of the orbiting scroll and the center of the fixed scroll are aligned with each other. Therefore, even when the fixed scroll or the orbiting scroll is deformed due to thermal expansion, the present invention can prevent the fixed wrap and the orbiting wrap from interfering with each other in a region where the amount of deformation is large, thereby preventing friction loss or abrasion between the fixed wrap and the orbiting wrap, and can suppress or minimize an increase in the gap between the fixed wrap and the orbiting wrap on the opposite side, thereby improving the compression efficiency of the compressor.
