Abstract
The invention relates to a positive displacement machine working according to the spiral principle, in particular a scroll compressor, comprising a compressor section and a motor section, wherein an orbiting displacement spiral and a counter spiral are arranged in the compressor section, which engage into one another in such a way that variable compression chambers are formed between the displacement spiral and the counter spiral in order to receive and compress a working medium flowing through a working medium circuit, wherein an electric motor is arranged in the motor section, which is drive-connected to the displacement spiral, and wherein a cooling device is provided for cooling the electric motor. The invention is characterized in that the cooling device is independent of the working medium circuit.
