A pressure wave generator (DWG) as well as a system and a method for generating a pressure wave, in particular for cleaning a vessel, e.g. a steam boiler or pipe, wherein the DWG includes a pressure chamber (11, 12), which can be filled with a working medium via a pressure chamber inlet, with at least two opposing pressure outlets (15), and furthermore an actuator chamber (18), which can be filled with an actuator medium via an actuator chamber inlet (5), and at least two opposing actuator outlets (8), which are connected to the pressure chamber (11, 12) by a passage. Furthermore, the DWG includes a closure element (13) in the pressure chamber (11, 12) which, in a closed position, closes the pressure chamber (11, 12) with respect to the pressure outlets (15) and, in an open position, allows the working medium to flow out through the pressure outlets (15). In addition, the DWG includes an actuator element (6) in the actuator chamber (18) which, in a closed position, closes the pressure chamber (11, 12) with respect to the actuator outlets (8) and, in an open position, allows the working medium to flow out through the passage (7) and the actuator outlets (8).

The invention relates to a pressure wave generator, and to a system and a method for generating a pressure wave, in particular for cleaning a container, e.g. a boiler or pipe. The pressure wave generator comprises a pressure chamber (11, 12) which is precipitable with a working medium via a pressure chamber inlet, with at least two mutually opposite pressure outlets (15), and furthermore comprises an actuator chamber (18) which is precipitable with an actuator medium via an actuator chamber inlet (5), and at least two mutually opposite actuator outlets (8) which are connected to the pressure chamber (11, 12) by a passage. Furthermore, the pressure wave generator comprises a closure element (13) in the pressure chamber (11, 12), said closure element, in a closed position, closing the pressure chamber (11, 12) in relation to the pressure outlets (15) and, in an open position, permitting the working medium to flow out through the pressure outlets (15). In addition, the pressure wave generator comprises an actuator element (6) in the actuator chamber (18), said actuator element, in a closed position, closing the pressure chamber (11, 12) in relation to the actuator outlets (8) and, in an open position, permitting the working medium to flow out through the passage (7) and the actuator outlets (8).
