3. Function
The gearbox is based on a single level worm-wheel transmission. The gear parts as well
as the storage are greased for life. The dosing stroke functions through a cam that the
membrane moves over a spring-loaded tappet. The siphon is reached through a spring-
loaded position.
Drive eccentric continues to run free until the plunger plate is reached again.
