PiezoInjektoren
PiezoInjektoren, or piezoinjectors, are precision injection devices that use the piezoelectric effect to generate rapid, high-pressure fluid pulses. In this system, a piezoelectric crystal or polymer is mechanically polarized. When a voltage is applied, the crystal changes shape, creating a mechanical displacement that drives a piston or valve in the injector. The resulting pressure spike forces a controlled volume of fluid out of the needle or nozzle.
The core components of a piezoinjector include the piezoelectric actuator, a piston or valve assembly, a sealing
Piezoinjectors are widely used in inkjet printing, where precise droplet ejection is required to achieve high
Compared with conventional solenoid injectors, piezoinjectors offer faster response, lower power consumption, and reduced mechanical wear
