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), 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).
A scroll positive displacement machine with a high-pressure chamber, a low-pressure chamber, an orbiting displacement spiral, a counter spiral and a counter-pressure chamber, which is arranged between the low-pressure chamber and the orbiting displacement spiral, wherein the orbiting displacement spiral engages into the counter spiral in such a way that, during operation, at least a first and a second compression chamber are temporarily formed for receiving a working medium, and wherein the orbiting displacement spiral has at least one passage opening for fluid connection with the counter-pressure chamber, wherein the at least one passage opening is arranged in the orbiting displacement spiral in such a way that, during operation, orbiting motion of the orbiting displacement spiral causes the at least one passage opening to be temporarily arranged at least in sections in the first compression chamber, and subsequently temporarily arranged at least in sections in the second compression chamber;
A scroll positive displacement machine with a high-pressure chamber, a low-pressure chamber, an orbiting displacement spiral, a counter spiral and a counter-pressure chamber, which is arranged between the low-pressure chamber and the displacement spiral, wherein the orbiting displacement spiral engages into the counter spiral in such a way that, during operation, at least a first and a second compression chamber are temporarily formed for receiving a working medium, and wherein the orbiting displacement spiral has at least one passage opening for fluid connection with the counter-pressure chamber, wherein the at least one passage opening is arranged in the orbiting displacement spiral in such a way that, during operation, orbiting motion of the orbiting displacement spiral causes the at least one passage opening to be temporarily arranged at least in sections in the first compression chamber, and subsequently temporarily arranged at least in sections in the second compression chamber;
