A pulse valve for generating a high-volume pulsating fluid stream from a fluid supplied to the pulse valve from a pressure-generating unit. Window cut-outs are disposed opposite one another in pairs, in a housing wall, and form a first channel for conducting a constant, stationary sub-stream, a second channel for generating a second sub-stream that forms a basic pulse component, and a third channel for generating a third sub-stream that forms an additional pulse component. A rotatable rotor shaft disposed in the interior of the housing is provided with respective rotor blade assemblies associated with the second and third channels respectively. Upon rotation of the rotor shaft, the rotor blade assemblies, in cooperation with boundary edges of the window cut-outs of the second and third channels, periodically either allow a fluid stream impinging on the pulse valve to pass through the housing, or to interrupt such passage.
