<p>The pump comprises a housing 13 defining a pump chamber which is divided into two compartments 21, 22 by a planar pumping element 20, extending substantially the full width of the chamber. The element is mounted along one edge on a shaft 16 and extends between an inlet 14 and an outlet 15. The element is made of a flexible material, so that, when the shaft is rotatably oscillated, the element flexes into an arched shape as shown. This flexing action acts to pump fluid with a substantially constant thrust.</p> |
