Title:
SCROLL COMPRESSOR
Document Type and Number:
WIPO Patent Application WO/2020/194994
Kind Code:
A1
Abstract:
A scroll compressor (10) is provided with: a cylindrical casing (10); and a circumferential guide (83) that is provided on an inner peripheral surface of the casing (10) and guides a compressed refrigerant. The circumferential guide (83) forms a circumferential flow path (90) that guides the compressed refrigerant in a circumferential direction to be discharged from an outlet (91) between the circumferential guide (83) and the inner peripheral surface. An outlet region (84) of the circumferential guide (83) is formed so that the circumferential flow path (90) expands toward the outlet (91). As a result, the oil loss of the scroll compressor can be suppressed.
