The gas-dynamic pressure wave machine which is destined for the charge air supply of an internal combustion engine comprises a rotor (6, 40) with cells (18, 41), a low pressure fresh air inlet channel (14, 38), a high pressure charge air channel (10, 32) leading to the internal combustion engine (1,
The gas-dynamic pressure wave machine which is destined for the charge air supply of an internal combustion engine comprises a rotor (6, 40) with cells (18, 41), a low pressure fresh air inlet channel (14, 38), a high pressure charge air channel (10, 32) leading to the internal combustion engine (1, 33), a high pressure exhaust channel (3, 31) coming from the internal combustion engine, and a low pressure exhaust channel (4, 35), the low pressure exhaust channel (4, 35) and the high pressure exhaust channel (3, 31) being enclosed in a gas enclosure (5, 34) and the low pressure fresh air inlet channel (14, 38) and the high pressure charge air channel (10, 32) being enclosed in an air enclosure (15, 39). In order to eliminate the detrimental pressure pulsations, on one hand, and to increase the compression efficiency, on the other hand, a direct connection (46) is provided between the high pressure charge air channel (32) and the high pressure exhaust channel (31), which connection preferably comprises a nonreturn valve (47).

[ What is claimed is:] [1.]1. A gas-dynamic pressure wave machine for a charge air supply of an internal combustion engine, the pressure wave machine comprising:a rotor;an air housing having an air inlet channel in communication with the rotor and a charge air channel leading from the rotor to the internal combustion engine;a gas housing having a first exhaust channel leading from the internal combustion engine to the rotor and a second exhaust channel in communication with the rotor and leading to the outside; anda dampening connection without a turbo charger and located between the charge air channel and the first exhaust channel, the dampening connection operable to remove detrimental pressure pulses and thereby raise pressure and compression efficiency of the pressure wave machine.
