Abstract (en)
[origin: WO2022161941A1] Scroll compressor (1), comprising: – a compression portion (10) having an inlet (11) for drawing a fluid into the compression portion (10), an outlet (12) for expelling the compressed fluid, a stationary plate (20) having a stationary spiral (21) and an orbiting plate (30) having an orbiting spiral (31), wherein the orbiting plate (30) can be made to orbit relative to the stationary plate (20), – an oil separator (45) for separating oil from the compressed fluid and a direct oil return line (50) for direct return of oil from the oil separator (45) to the compression portion (10), wherein the direct oil return line (50) has at least one discharge opening (59a, 59b). The direct oil return line (50) also comprises an outgassing chamber (54) arranged between the first flow valve (53) and the discharge opening (59a, 59b), and a fluid return line (70) for returning fluid from the outgassing chamber (54) into the compression portion (10).
