Claims (11)
- 1. einer Druckkammer mit mindestens einem Einlaß für das Fluid und einem Auslaß zum Ausgeben von Fluidtropfen und
- 2. einer Druckimpuls-Erzeugungsvorrichtung zum Erzeugen eines Druckimpulses in der Druckkammer zwecks Ausstoßen eines Fluidtropfens aus dem Auslaß der Druckkammer, dadurch gekennzeichnet,
- 3. daß die Druckkammer als reflektives akustisches Element für die in dem Fluid durch den Druckimpuls erzeugten akustischen Wellen ausgebildet ist.
- 1. a pressure chamber with at least one inlet for the fluid and an outlet for dispensing fluid drops and
- 2. a pressure pulse generating device for generating a pressure pulse in the pressure chamber for the purpose of ejecting a drop of fluid from the outlet of the pressure chamber, characterized in that
- 3. that the pressure chamber is designed as a reflective acoustic element for the acoustic waves generated in the fluid by the pressure pulse.
