Abstract (en)

[origin: EP3919742A1] A scroll compressor (1) includes a tubular casing (10) and a circumferential guide (83) formed on an inner peripheral surface of the casing (10) to guide a compressed refrigerant. The circumferential guide (83) and the inner peripheral surface define therebetween a circumferential flow path (90) configured to guide the compressed refrigerant in a circumferential direction and cause the compressed refrigerant to flow out through an outlet (91). The circumferential guide (83) includes an outlet region (84) formed into a shape that allows the circumferential flow path (90) to widen toward the outlet (91). This configuration can reduce oil loss of the scroll compressor.
