Abstract

Der insbesondere für Luftpumpen mit einer Membran als Pumporgan vorgesehene piezoelektrische Pumpenantrieb, weist ein Resonanzschwingsystem auf, das mit wenigstens einer mittels einer Resonanzfeder (11) federelastisch gelagerten Resonanzmasse (12) versehen ist und dessen Schwingungen von wenigstens einem elektrisch aktivierten Piezoelement (1) erzeugt werden. Von diesem Schwingsystem wird das Pumporgan oszillierend angetrieben. Das Piezoelement (1) steht über die mit der Resonanzmasse (12) versehene Resonanzfeder (11) mit dem Pumporgan in kraft- und bewegungsübertragender Antriebsverbindung. Dabei ist als Resonanzfeder (11) und Träger der Resonanzmasse (12) wenigstens eine solche stab-, blatt- oder bandförmige Feder (21) vorgesehen, auf welche das Piezoelement (1) an einem kurzen Hebelarm (23) einwirkt, und die an einem längeren Hebelarm (24) die Resonanzmasse (12) trägt, so dass zwischen den antreibenden Bewegungsamplituden des Piezoelements (1) und den resultierenden Bewegungsamplituden der Resonanzmasse (12) eine positive mechanische Wegübersetzung besteht.

Figure imgaf001
The piezoelectric pump drive, which is provided in particular for air pumps with a membrane as a pump element, has a resonance oscillating system which is provided with at least one resonance mass (12) mounted resiliently by means of a resonant spring (11) and whose oscillations are generated by at least one electrically activated piezo element (1) , From this vibration system, the pump body is driven oscillating. The piezoelectric element (1) is connected to the pumping organ via the resonance spring (11) provided with the resonance mass (12) in a force-transmitting and motion-transmitting drive connection. In this case, as a resonant spring (11) and carrier of the resonance mass (12) at least one such rod, sheet or band-shaped spring (21) is provided, on which the piezoelectric element (1) on a short lever arm (23) acts, and at a longer lever arm (24) carries the resonance mass (12), so that between the driving movement amplitudes of the piezoelectric element (1) and the resulting movement amplitudes of the resonance mass (12) is a positive mechanical path translation.
