Shutoff Pressure Line, Feed; Rotor; Stator - Mercedes-Benz OM 471 Introduction Into Service Manual

Shutoff pressure line, feed (16)

The shutoff pressure line, feed (16) continuously supplies the slide
ring seal (14) with engine coolant. The engine coolant is fed back
to the cooling circuit of the engine via the connection to the
shutoff pressure line, return (20).

Rotor (17)

The rotor (17) is driven by the retarder shaft (15) via the twisted
teeth (13) and feeds the engine coolant to the stator (18) through
the rotational movement of its blades.

Stator (18)

The stator (18), which is fixed to the retarder housing, takes in the
rotating engine coolant with its blades through the filling slot (19)
and directs it back to the rotor (17). The resulting frictional forces
brake the rotor (17).
