Abstract: A multi-flow gas-dynamic pressure-wave machine, the rotor of which comprises at least one intermediate tube which subdivides the cell zone into at least two flow channels. The cell walls of adjacent flow channels are circumferentially staggered by essentially one-half the circumferential interface between such cells to produce a reduction in noise due to the beat interference produced by the sound pressures occurring in the cells adjacent to one another in the radial direction. The rotor may be provided with a concertina-shaped or undulation-shaped intermediate tube whereby there occurs a more balanced distribution of stresses, requiring less accelerating power.
