7.7 Injection unit (option)
After cleaning, the torch is moved from the clamping position
over the injector
for injection with the gas nozzle
In this position, the gas nozzle
actuates the roller lever
so that the directional valve
is switched. The compressed
air is no longer supplied to the stroke cylinder but to the injector
.
Fig. 12 Pneumatic plan on page EN-17
When the control signal, stroke = 1, is set again, injection starts. The air flowing through the injector
creates a vacuum in
. The anti-spatter fluid is sucked in from the anti-spatter agent tank
and added to the circulating air.
