When comparing the construction of the com-
bination governor with that of the variable
speed governor, the governor spring and the
governor lever assembly of the combination
governor differ from those of the variable
speed governor.
As shown in Fig. 24 a yoke is attached to the
control lever shaft assembly, and the governor
spring and the partial load spring, with a pre-
set force, are installed inside the yoke. A
damper spring is installed at the end of the
yoke.
Idling control is performed by the start-idling
spring, which is installed between the top of
the tension lever and the starting lever in the
governor lever assembly.
