Piezo-actuator e.g for fuel injection valve in motor vehicle, has each piezo-layer formed from piezo-foils and inner electrodes associated with each piezo-layer are outside on piezo-layer

Magnetic valve, for a motor fuel injector, has a coil to energize a magnet to open/close the valve unit at the valve seat

Piezoelectric actuator for an internal combustion engine injection valve has an actuator body to expand and contract when operating the piezoelectric actuator

Piezoelectric Actuator and a method for its manufacture

Piezoelectric actuator comprising a flexible, surface-adhesive outer electrode for contacting a terminal contact

Piezo actuator and a method for producing the same

Piezoelectric multilayered actuator

Piezoelectric actuator for positioning with heat dissipating inactive end section

Compensation of batch variation in the travel due to variations in the layer thickness or number of layers in multi-layer piezoelectric elements

Method for controlling at least two piezoelectric actuators of a fuel injection system of a combustion engine where control is corrected based on a difference between measured charge energy and a target value
