ABSTRACT:
A generating device (1) for generating a useful stream of a medium (2) comprises at least a medium stream source (14) for generating a high-frequency medium stream (15) and at least a medium stream diode (36, 37) for cooperating with the generated medium stream (15), and at least one medium stream sink (40, 41) for cooperating with the medium stream influenced by the medium stream diodes (36, 37), wherein the at least one medium stream sink (40, 41) suppresses high-frequency stream components in the medium stream such that a useful medium stream (2) in a low-frequency range is obtained.
