Abstract

See full text

The invention relates to a scroll-type positive displacement machine, in particular a scroll compressor, comprising a highpressure chamber (11), a low-pressure chamber (12), an orbiting displacement spiral (13), a counter spiral (14), and a counterpressure chamber (15) which is located between the low-pressure chamber (12) and the displacement spiral (13), wherein an outlet opening (16), through which a compressed working medium flows into the high-pressure chamber (11) during operation, is centrally arranged in the counter spiral (14) in a high-pressure region, and wherein the displacement spiral (13) has at least a first and a second passage opening (17a, 17b) for fluidic connection to the counter-pressure chamber (15), wherein at least the first passage opening (17a) is arranged in the region of the outlet opening (16) so that, during operation, the first passage opening (17a) and the outlet opening (16) temporarily overlap at least in sections.
