The guide-lever, the floating-lever and the link will push the control-rack to the full-load
position by transferring

To
transfer
the
control-rack
to
the full-load position, it
is
enough
to
move the
control-lever slightly from
the
idling position. Then the ungleich-spring
in
the tension lever
(if the spring
is
involved
in
it) becomes
effe..."1:ive.
The injection pump supplies much fuel
to
the cylinder of engine and the r.p.m. rises. As soon
as
the centrifugal force exceeds the
tension
of
the
governor-spring, the flyweight will spread itself outside and pulls back the
guide-bush, shifter, floating-lever and the control-rack
in
the direction of "fuel decrease".
The
r_p.m.
of
the
engine
will
not
rise
from this point and it
is
maintained
by
the governor
under a fixed condition.
When
the
control-lever
is
transferred
to
the position of the highest r.p.m. (Fig. 7), the
governor works as shown
in

the governor-spring stretches
the
