摘要：
A new working principle of micro mechanical pump is proposed. With a round-path chamber and two no-moving-part-valves, this pump takes full advantage of fluid inertia and forms two-stage hydrodynamics mechanism. By reducing the reverse flow in chamber and by increasing resistance difference of back-and-forth flow, higher efficiency, higher pressure and less output fluctuation could be expected. The emulation results prove the feasibility of the principle.
