Abstract
In a multiflow gas-dynamic pressure-wave machine, with a rotor, a housing surrounding the rotor as well as an air housing and a gas housing with ducts for the intake and discharge of the gaseous working substance, the cell ring of the rotor is subdivided by three intermediate pipes into four concentric flows placed between a hub pipe and a shroud. The two outer flows and the two inner flow each have the same number of cells. The radially directed cell walls of the two outer flows and of the two inner flows are mutually offset by a half cell division each.
