The pressure and volume regulation is designed as a rota-
ry regulator between the trigger gun and the spray lance.
There are two ceramic discs within the high pressure chan-
nel.
The ceramic disc is rigidly connected with the connection
of the trigger gun. The ceramic disc is connected to the ro-
tary switch and therefore adjustable. Offset holes in the ce-
ramic discs can adjust the flow volume and the pressure
when rotating the discs.
This illustration shows the two overlapping ceramic discs
and the water flow (blue) with different opening angles
(from 0° to 90°).
With the minimal setting, the water flows through a small
hose in the middle of the ceramic discs.
