发明名称 Method for manufacturing piezoelectric actuator utilized in common rail injection system for combustion engine, involves forming sinter lattice exhibiting three weight percentages of dopant portion, in lead zirconate titanate stack
摘要 <p>The method involves forming lead zirconate titanate (PZT) stack from multiple PZT components. A sinter lattice exhibiting three weight percentages of dopant portion i.e. silicon dioxide portion, is formed in the stack. The lattice is made of aluminum base stack-cemented material. The stack is provided with electrodes to form a piezoelectric actuator. A multi-part sacrificial plate (2) i.e. ballast plate, exhibiting the three weight percentage of dopant portion is latched with an inner electrode through PZT latches (1). The lattice and/or the plate are made of different aluminum oxide portions.</p>
