DESCRIPTION AND OPERATION (Continued)
IMPELLER
The impeller (Fig. 10) is an integral part of the
converter housing. The impeller consists of curved
blades placed radially along the inside of the housing
on the transmission side of the converter. As the con-
verter housing is rotated by the engine, so is the
impeller, because they are one and the same and are
the driving member of the system.

TURBINE
The turbine (Fig. 11) is the output, or driven, mem-
ber of the converter. The turbine is mounted within
the housing opposite the impeller, but is not attached
to the housing. The input shaft is inserted through
the center of the impeller and splined into the tur-
bine. The design of the turbine is similar to the
impeller, except the blades of the turbine are curved
in the opposite direction.
