Abstract
A pump comprising a side wall closed at each end by an end wall forming a cavity for, in use, containing a fluid, one or more actuators each operatively associated with one or more of the end walls to cause an oscillatory motion of the associated end wall(s) whereby, in use, these axial oscillations of the end wall(s) drive substantially radial oscillations of the fluid pressure in the cavity, two or more apertures in the cavity, a valve disposed in at least one of the apertures, wherein the actuator(s) is arranged to be non-axisymmetric in use such that, in use, a pressure oscillation with at least one nodal diameter is generated within the cavity.
