The pressure and volume regulation is performed via
a rotating regulator between the gun and the spray
lance.
There are two ceramic discs within the high pressure
channel.
One ceramic disc is rigidly connected to the gun con-
nection. The other ceramic disc is connected to the
rotating regulator and therefore adjustable.
Offset holes in the ceramic 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.
