ABSTRACT:
A constrained wave pump for pumping fluids by oscillation of an elastic medium. Coaxially arranged cylindrical constraining surface and elastic member define a channel having an entrance and an exit port. A shaft creates variable frequency longitudinal oscillations in the elastic member which generate wave propagation therein. The peaks of the generated waves form a fluid seal with the constraining surface to produce a fluid pumping action from the entrance to the exit port.
