CENTRIFUGAL GOVERNOR Presented by Rohan
Lyall Objective -To explain what a
centrifugal governor is -To explain how it
works -To present its applications and benefits
2
What is a Centrifugal Governor?
-The first governor was designed by James Watt in
1788 - A Governor is a feedback device on a
machine or engine that is used to provide
automatic control, as of speed, pressure, or
temperature - A Centrifugal Governor (also
known as Watt or fly-ball governor) is a specific
type of governor, that controls the speed of an
engine, by regulating the fuel admitted
3
How Does it work? -Uses the principal of
proportion control -A proportional control
system - a type of linear feedback control
system. -output signal of a system is passed
back to the input -Two rotating masses that
indirectly control the speed of the
engine -These rotating masses are based on
centrifugal force - As engine speed increases,
Centrifugal force increases on masses which
causes an upward lift. -The rotating masses are
attached to valves that control the fuel flow
into cylinders, which then controls the speed of
the engine.

• APPLICATIONS OF THE CENTRIFUGAL GOVERNOR
• - Governors are used frequently in a variety of
  machine applications.
• - They are seen on steam engines, internal
  combustion engines and variously fueled turbines
• - They are used in
• - Automobiles to restrict/maintain engine RPM,
  total speed
• - Governors protect engine from excessive
  rotational speed
• - used in some high performance cars to limit
  vehicle speed
• - Used in a spring-loaded record player, and
  telephone dials to limit the speed.
