Abstract
A piezo-electric fluid pump is provided including a main housing; a fluid reservoir located within the main housing; a piston head moveably mounted within the main housing; a piezo-electric stack; a bias mechanism arranged to couple the piston head and piezo-electric stack and maintain the piezo-electric stack in compression; an outlet plate statically mounted within the main housing adjacent to the piston head, wherein the adjacent surfaces of the outlet plate and piston head define a pumping chamber; an inlet disc valve arranged to permit a one-way flow of fluid from the reservoir into the pumping chamber; and an outlet disc valve arranged to permit a one-way flow of fluid out of the pumping chamber. The combination of pre-loading of the piezo-electric stack in compression and use of inlet disc valve enables the piezo-electric pump to exhibit substantial improvement to the pressure and flow capability compared to other piezo-electric pumps.
