Displacement machine according to the spiral principle, method for operating a positive displacement machine, Verdrängerspirale, vehicle air conditioning system and vehicle

The invention relates to a displacement machine according to the spiral principle, in particular a scroll compressor (10), with a high-pressure region (47) comprising a high pressure chamber (40) of the Weitern with a low pressure chamber (30) and an orbiting Verdrangerspirale (31) in a against scroll (32) engages in such a way that between the Verdrangerspirale (31) and the counter-spiral (32) compression chambers (65a, 65b, 65c, 65d, 65e) are formed to receive a working fluid, wherein between the low pressure chamber (30) and the Verdrangerspirale (31) is formed a back pressure chamber (50). According to the invention the Verdrangerspirale (31) at least two passages (60, 61) for producing at least temporarily a fluid communication between the back pressure chamber (50) and at least one of the compression chambers (65a, 65b, 65c, 65d, 65e), wherein a first passage (60) is substantially the Verdrangerspirale (31) is formed in a central portion (38) at least one second passage (61) is formed in the initial region (37) of Verdrangerspirale (31).
