GOVERNOR MECHANISM

Mechanism
The governor
is
centrifugal flyweight type, which means a flyweight is fitted to the governor
gear.
The governor sleeve is as-
sembled
so
that it may slide toward the direction
of
the axis
of
the pump shaft, and it
is
in
contact with the flyweight. The
governor sleeve gets
in
touch with the governor yoke, and through the governor lever it makes the control rack
of
injection
pump operate.
This
mechanism enables to maintain constant operation irrespective
of
