CA 2470681

A pump includes an outer body; and a wall within said outer body. The outer body and the wall define a pumping cavity and an excitation cavity within the outer body. An excitable medium is contained within the excitation cavity. An excitation source is coupled to said excitable medium. This excitation source is operable to excite the excitable medium and create a standing wave therein. The standing wave acts through the wall to pump said fluid through said pumping cavity. Advantageously, the excitable medium is isolated from the pumped fluid by the wall.

L'invention concerne une pompe constituée d'un corps externe renfermant une paroi. Le corps et la paroi définissent une cavité de pompage et une cavité d'excitation à l'intérieur du corps externe. Un milieu excitable est contenu dans la cavité d'excitation. Une source d'excitation est couplée à ce milieu excitable. Cette source d'excitation peut être utilisée en vue d'exciter le milieu excitable et d'y créer une onde stationnaire. L'onde stationnaire agit à travers la paroi afin de pomper le fluide à travers la cavité de pompage. Dans un mode de réalisation avantageux, le milieu excitable est isolé du fluide pompé par la paroi.
