4. (Mach.) A contrivance applied to steam engines, water
wheels, and other machinery, to maintain nearly uniform
speed when the resistances and motive force are variable.
Note: The illustration shows a form of governor commonly used
for steam engines, in wich a heavy sleeve (a) sliding
on a rapidly revolving spindle (b), driven by the
engine, is raised or lowered, when the speed varies, by
the changing centrifugal force of two balls (c c) to
which it is connected by links (d d), the balls being
attached to arms (e e) which are jointed to the top of
the spindle. The sleeve is connected with the throttle
valve or cut-off through a lever (f), and its motion
produces a greater supply of steam when the engine runs
too slowly and a less supply when too fast.
[1913 Webster]
Governor cut-off (Steam Engine), a variable cut-off gear in
which the governor acts in such a way as to cause the
steam to be cut off from entering the cylinder at points
of the stroke dependent upon the engine's speed.

the action of a liquid in flowing; a cataract.
