Piezoelectric Pump using Amplified Displacement

摘要

The present invention relates to piezoelectric pumps , and more particularly, a large generating force to displacement of the pumping stack-type PZT will be provided to the amplification chamber for the liquid to be amplified by the pressure medium of the displacement amplifying the piezoelectric pump is pumping to amplify the displacement . Displacement amplification type according to the present invention by the same configuration as the piezoelectric pump has a large effect in generating force is applied to the multilayer PZT , while it is possible to increase the displacement of the diaphragm to pump the fluid to increase the pumping capacity of the fluid . ;
