Research in rotary piston machines for compressible fluids

摘要

Rotary piston machines are a subgroup of the displacement machines, which are characterized by sealed rotating working chambers with volumes cyclically changing during a working cycle. This subgroup includes, for example, the roots blowers, scroll compressors, screw compressors or also the spindle vacuum pumps. For more than 100 years, rotary piston pumps have been used both in industry and in our immediate surroundings, e.g. in refrigerators mounted in motor vehicles. They represent the most commonly used type of compressor.
