The figure shows the main parts and the work principle of the Air LiHa systems air
chamber and plunger drive.
Principle of the Air LiHa plunger drive
A motor drives a threaded spindle via a gear pair. To aspirate liquid, the spindle rotates
and the thread moves the nut and the attached plunger upwards. The vacuum in the
chamber sucks the liquid into the disposable tip.
