Abstract (en)

A scroll compressor (1) includes: a casing (10); a discharge cover (100) dividing a space in the casing into a high-pressure side space (12b) and a low-pressure side space (12a); an orbital scroll (40) positioned in the low-pressure side space and which is eccentrically rotated with respect to the axis; and a fixed scroll (30) positioned between the discharge cover and the orbital scroll, a compression chamber (31) to which refrigerant introduced from the low-pressure side space being formed between the fixed and orbital scrolls. A discharge port (36) through which the refrigerant compressed in the compression chamber is discharged to the high-pressure side space is formed so as to be passed through the fixed scroll and the discharge cover, an annular injection space (S) surrounding the discharge port and a communication path communicating the injection space with the low-pressure side space are formed between the fixed scroll and the discharge cover, and the scroll compressor further includes an injection pipe (130) through which liquid refrigerant is introduced to the injection space from an outside thereof.
