Abstract

A pressure wave machine with integrated combustion has a cellular wheel (10) containing a number of cells (16) in which an always recurring ignition and combustion process takes place. To maintain this always recurring process, neither a supply of ignition energy from the outside nor a control intervention should be necessary. Hot-gas channels (18) are provided, by means of which hot gas is taken from one cell (16), in which the combustion step belonging to a cycle has been completed, and recycled to a cell (16) which contains the fuel/air mixture which is to be ignited.
