Abstract[German]
) (220) fest verankert ist, wobei eine zweite Seite der Ventilstruktur (212) frei beweglich ist, um einen Strömungswiderstand eines Fluids in Abhängigkeit von einer Strömungsrichtung (222) des Fluids zu erzeugen, - zumindest einen Anregungsmechanismus zum Anregen des einen oder der mehreren Ultraschallerzeugungselemente (202).[English]
) (220), and a second side of the valve structure (212) being free to move in order to generate a flow resistance for a fluid depending on a flow direction (222) of the fluid, - at least one excitation mechanism for exciting the one or more ultrasound generating elements (202).[French]
) (220), et un second côté de la structure de soupape (212) étant libre de se déplacer afin de générer une résistance à l'écoulement pour un fluide en fonction d'une direction d'écoulement (222) du fluide, - au moins un mécanisme d'excitation pour exciter le ou les éléments de génération d'ultrasons (202).
