Piezoelectric high voltage impact mechanism

摘要

A new and improved piezoelectric high voltage impact mechanism uses an actuator with slanted internal walls to tilt a straight actuating spring. The spring constrains a hammer so that the hammer is held on a ledge in the body as actuation is initiated. Energy is stored in the spring during actuation and the actuator pushes the hammer off the ledge, initiating the impact. Component parts and assembly are simplified compared with prior art devices.
