Title: COMPRESSOR HAVING MUFFLER FUNCTION
Abstract:
A compressor (10) compresses a drawn-in low-pressure refrigerant and discharges high-pressure refrigerant. The compressor (10) is provided with a first throttle part (S1), a widened flow channel part (E), a second throttle part (S2), and a compression element (30). The first throttle part (S1) receives intermediate-pressure refrigerant from an injection tube (69) of a refrigerant circuit (100). The widened flow channel part (E) receives refrigerant from the first throttle part. The second throttle part (S2) receives refrigerant from the widened flow channel part. The compression element (30) has a compression chamber (33) that receives refrigerant from the second throttle part. The flow channel cross-sectional area (AS1) of the first throttle part is less than both the flow channel cross-sectional area (A1) of the injection tube and the flow channel cross-sectional area (AE) of the widened flow channel part. The flow channel cross-sectional area (AS2) of the second throttle part is less than the flow channel cross-sectional area (AE) of the widened flow channel part.
