 direction of impeller rotation because of
a sprag clutch built into the stator; and
a turbine which is driven by the fluid
thrown from the impeller. Each of these
units contain vanes or blades which act
upon, or are acted upon, by fluid within
the converter. This fluid is thrown from
the impeller (acting as a pump), through
the turbine blades, across the stator,
and back to the impeller. When the engine
is operating under load, turbine speed is
slowed so that fluid passing through the
turbine and stator adds its energy to
that of the impeller, thus increasing

ceases, and the converter acts merely
as a fluid coupling between engine and
