Abstract (en)

[origin: WO2021204591A1] The invention relates to a scroll-type positive displacement machine, in particular a scroll compressor, comprising a high-pressure chamber (11), a low-pressure chamber (12), an orbiting displacement spiral (13), a counter spiral (14), and a counter-pressure chamber (15) which is located between the low-pressure chamber (12) and the displacement spiral (13), the displacement spiral (13) engaging in the counter spiral (14) in such a way that, during operation, at least a first and a second compression chamber (16a, 16b) for receiving a working medium are temporarily formed, and the displacement spiral (13) having at least one passage opening (17) for fluidic connection to the counter-pressure chamber (15), wherein the passage opening (17) is located in the displacement spiral (13) in such a manner that, during operation, due to the orbiting movement of the displacement spiral (13), at least sections of the passage opening (17) are temporarily arranged in the first compression chamber (16a) and subsequently at least sections of the passage opening are temporarily arranged in the second compression chamber (16b).
