2.2 Swivel housing:
To keep the swivel housing centered on the central body ball bearings are used, one in the material
chamber (1) and one in the air chamber (see page 10).
There is a front (2) and a back (3) drainage chamber in the swivel chamber that are both sealed by
additional seals (4) to prevent material leakage into the air chamber and onto the car chassis.
Note the material inlet (5), material return (6), and drainage channels (7) in the swivel housing.
The internal chamber rings are all locked in place by interconnecting pins (8) which are locked to the inside
of the material chamber (9) with one pin (10).
