Abstract
A dual-cavity pump having a pump body with a substantially elliptical shape including a cylindrical wall closed at each end by end plates is disclosed. The pump further comprises a pair of disc-shaped interior plates supported within the pump by a ring-shaped isolator affixed to the cylindrical wall of the pump body. The internal surfaces of the cylindrical wall, one of the end plates, one of the interior plates, and the ring-shaped isolator form a first cavity within the pump. The internal surfaces of the cylindrical wall, the other end plate, the other interior plate, and the ring-shaped isolator form a second cavity within the pump. The interior plates together form an actuator that is operatively associated with the central portion of the interior plates. The illustrative embodiments of the dual-cavity pump have three valves including one located within a common end wall between the cavities of the pump. Methods for fabricating the pump are also disclosed.
