the length of the arm of moment against the revolving axis
will
change together with the
tension of the governor spring. This
is
because, as aforesaid,
that
the revolving center of the
swivel· lever and the
spring-eye of the tension lever are eccentric each other. The set-load of
.the governor spring may adjust the adjsuting-screwof
the knackel.
The stopper-bolt attached
to
the back of governor-cover
may
be
adjusted so that it
will
contact with
the
knuckle when the control-lever barely reaches its "STOP" position.
In
the
governor equipped with a stop-device, this stopper-bolt may
be
used as a idling-stopper. The
ungleich equipment may be screwed in
the
tension-lever if necessary.
This
is
a bush with a pin having the spring load and may
be
controlled from outside by
taking off the closing-cover
of
the
governor-cover,
as
it
is
designed.
The ungleich device
will
amend the full-load jet volume of the injection pump within a
specified scope according
to
the
set-load
of
the spring which
is
adjusted
by
the constant of
equipped spring, stroke and shim so as
to
be
fit successively for the necessary volume of fuel
for engine between the r.p.m.
of
idling and that of full-load.
The adjustable screw bush
is
inserted
in
about the middle of the governor-cover, and the
idling-sub-spring which
is
involved
in
the
bush may
be
adjusted so
that
it
will
affect the
control of non-load high-speed rotation as little
as
possible. However,
in
case when the
ungleich
is
unnecessary
at
the full load jetting volume
but
the firm control
is
needed
at
a
large stroke
of
control-rock
at
a lower r.p.m. of idling, a comparatively weak sprIng shall
be
involved
in
the bush
of
the ungleich-device. This spring,

case when the engine
is
