Title:
SCROLL COMPRESSOR
Document Type and Number:
WIPO Patent Application WO/2018/051750
Kind Code:
A1
Abstract:
A scroll compressor (1) is provided with: a stationary scroll (5), a turning scroll, a suction part, a discharge part, and an electric motor. A scroll end plate surface (5f) has formed thereon, at locations on the outer side of a lap (5a), a groove part (5g) recessed with respect to the end plate surface, and a flange part (5h) protruding with respect to the groove part. When a perfect circle (Lci) to be used as a reference is drawn using, as the radius, the distance (t) between the center point (O) of the scroll where the flange part is formed and a winding-end point (5m) of an involute curve of the scroll, the flange part (5h) is an area (R1) which remains after excluding, from an area (R0, R1) that protrudes from the perfect circle, an area (R0) that is contiguous with the winding-end point. This scroll compressor (1) improves reduction in sliding loss using a simple structure and simultaneously, improves overall reduction in leakage loss of refrigerant in a compression chamber.
