Abstract

Apparatus for generating a pulsating pressurized fluid jet are disclosed. One disclosed example includes a line system having at least one nozzle with at least one nozzle orifice from which a pulsating fluid jet of pressurized fluid emerges, and a chamber having a pressure wave generating device to generate fluid pressure waves, where the chamber is in fluid communication with the line system through an outlet opening for the generated fluid pressure waves. The disclosed example also includes a setting device for controlling the amplitude of the fluid pressure waves in the line system upstream of the at least one nozzle orifice where the setting device sets a quotient of a path length of the fluid pressure waves between the outlet opening and the at least one nozzle orifice, and the wavelength of the fluid pressure waves in the line system.
