In order to provide a device for producing a pulsating fluid stream, which is of simple construction and is easily producible and which enables a pulsating fluid stream to be produced at a comparatively high frequency, there is proposed a device for producing a pulsating fluid stream which comprises a fluid inlet, a fluid outlet and a blocking element that is arranged between the fluid inlet and the fluid outlet and is rotatable about a rotational axis, wherein the blocking element comprises a blocking member which cyclically closes and opens a fluid passage from the fluid inlet to the fluid outlet.
