Atomizer body and sleeve
The atomizer body covers valve block and turbine. It protects the
internal components against soiling.
In addition, the atomizer body insulates the grounded components
inside against the high-voltage carrying electrodes.
To protect the short rinse from high voltage, there is a sleeve. The
sleeve is pushed onto the valve block, before the atomizer body is
mounted.
At the front end of the atomizer body is the shaping air ring. The
shaping air ring is an integral part of the atomizer body.
4.4.5.1
The shaping air
The atomizer has two independent shaping airs. Shaping air 1 is
passed through the valve block and the turbine to the shaping air ring
in the atomizer body.
Shaping air 2 is passed through the space between valve block and
atomizer body to the shaping air ring.

Control of shaping air
From the air quantity control, a predetermined amount of air is
conducted through hoses and in the atomizer through channels and
settling zones to the nozzle circuit.
The shapes and positions of the channels and settling zones in the
body of the atomizer allow a uniform distribution of the shaping air to
all the nozzles of the ring.
