With this system, the tank lid and metering valve
are one unit.
In the valve housing, there is a ring-shaped
metering channel, the cross-section of which is
increasing.
The inlet and outlet are connected with this
metering channel. Depending on the position of
the valve housing which can be shifted with the
metring knob, the open cross-section of the
metering channel will change. Thus the amount
of detergent taken in can be continuously mete-
red.
