Abstract
In a pressure wave machine with integrated combustion, which consists essentially of a rotor (1) which rotates between two side parts (4), (5) and has cells (2) in which an ignition and combustion process takes place repetitively, cooling air conduits (7) are arranged in the casing and passages (3) are arranged in the rotor (1) below and above the cells (2), viewed in the radial direction. The rotor (1) can be additionally surrounded at its inner periphery and outer periphery by at least one sheet-metal guide (8) in order to form further cooling passages (6), the internal space of the pressure wave machine casing being connected to the low-pressure outlet. For cooling the rotor of the pressure wave machine, a small part of the entering air is branched off before the admixture of the fuel, is led through the casing by cooling air conduits (7) and is subsequently guided through the passages (3), the cooling air itself then being subjected to its own pressure wave process.
