This invention relates to- improvements in en

sponsive control units adapted for use with in
vention, conside?ed'in connection with the ac
companying drawings, in which:
'

An object of the invention, generally stated, is
utilized to eifect'speed regulation ofthe engine
attained in a governor for the purpose noted, and
through the governor; Fig. 2 is a vertical sec
which 'is characterized by an improved degree
tional elevation throughthehousing appearing
in Fig. 1, and illustrating a governor assembly
of a design in accordance with the present inven

engine speed, substantially throughout the pre
determined speed range through which the gov
tion; Fig. 3 isa generally vertical sectional ele

example, Vof .the fuel supply of the associated en

An additional important object of the present
invention, when embodied ina centrifugal gov
ernor of a type in which the weights are opposed
by spring loading, is to provide a closely prede
20 termined variation of the effective spring rate, as
the yspring loading is varied to change the speed
setting of the governor and the engine with which
it is associated.
A further object of the invention is attained in
25 an improved governor assembly for use particu
larly on internal combustion engines and which
