Title:
METHOD AND APPARATUS FOR SCAVENGING ENERGY DURING PUMP OPERATION
Document Type and Number:
WIPO Patent Application WO2006074039
Kind Code:
A3
Abstract:
A pump comprises a body for at least partially defining a pump chamber (28); a pump member, such as a diaphragm (26) or a valve (130), which undergoes displacement when acting upon a fluid in the pumping chamber; and a piezoelectric element which responds to the displacement of the pump member to generate an electric current. The electric current generated by the piezoelectric element is preferably applied to a charge storage device, such as a capacitor or battery.
