摘要：A valve-less piezoelectric pump with hackle chamber (HC) is presented. The chamber bottom of the pump is designed as a waves shape. The HC and the opposite piezoelectric vibrator constitute a series of hackle shape ducts in the chamber. Different flow resistances are produced between the suction stroke and the discharge stroke of the pump. The different flow resistances will generate net flow when the pump works. The presented pump is successful to minimize the valve-less piezoelectric pump by eLiminating the regular diffuse/nozzle elements outside the chamber. The theory on the pump working is analyzed. The flow field in chamber is simulated for an intuition. Finally, to verify the theory, a group of tests are performed. ? 2011 IEEE.
