Document Type and Number:
Japanese Patent JP2855846
Kind Code:
B2
Abstract:
The invention relates to a piezoelectric pump using a piezoelectric actuator. The piezoelectric pump comprises an upper pump chamber main body having three pump chambers, a lower pump chamber main body having three pump chambers, and a piezoelectric actuator which has three actuator segments. The piezoelectric actuator is supported between the upper pump chamber main body and the lower pump chamber main body. The resultant piezoelectric pump has a simple and small structure and a high pump efficiency because both of the paired upper and lower pump chambers can be driven by an associated actuator segment.
