High power FI micropump
High power FI micropumps have been proposed and developed for micro fluid power sources. The structure of the FI micropump is like a piezoelectric diaphragm pump, but the outlet check valve is replaced by a small diameter pipe. By using the fluid inertia (FI) in the outlet pipe, the FI micropump can generate high output fluid power.
