FAQs on What is Proell Governor in types of Governors, TOM, Mechanical Engineering, GATE Video Lecture
| 1. What is a Proell Governor? |  |
Ans. A Proell Governor is a type of mechanical governor used in engines to control the speed. It consists of a rotating flywheel attached to the engine shaft and two pivoting arms with weights on one end. As the engine speed increases, centrifugal force causes the weights to move outwards, which in turn actuates a mechanism to control the fuel supply and maintain a constant speed.
| 2. How does a Proell Governor work? | |
Ans. A Proell Governor works based on the principle of centrifugal force. As the engine speed increases, the centrifugal force acting on the weights attached to the pivoting arms also increases. This force causes the weights to move outwards, which in turn compresses a spring or actuates a mechanism to adjust the fuel supply. By controlling the fuel supply, the governor maintains a constant speed even when the engine load changes.
| 3. What are the advantages of using a Proell Governor? | |
Ans. Some advantages of using a Proell Governor include:
- It provides a relatively stable and accurate control of engine speed.
- It can handle sudden load changes and maintain a constant speed.
- It does not require an external power source as it operates based on the engine's rotational motion.
- It is relatively simple in design and does not require complex mechanisms.
| 4. Are there any limitations or drawbacks of the Proell Governor? | |
Ans. Yes, there are some limitations of using a Proell Governor:
- It may not be suitable for very high-speed engines due to the limitations of the mechanical components.
- The response time of the governor may not be as quick as electronic or digital control systems.
- It requires regular maintenance and adjustment to ensure optimal performance.
- It may not provide precise speed control in certain applications that require very tight speed regulation.
| 5. Where are Proell Governors commonly used? | |
Ans. Proell Governors are commonly used in various types of engines, including internal combustion engines and steam engines. They are often found in applications such as generators, pumps, and industrial machinery, where maintaining a constant speed is critical for efficient operation. Additionally, they can be found in some automotive engines, although electronic control systems are more prevalent in modern vehicles.

The next type of governor which we are
seeing it is called as Proell governor
proell governor is also a centrifugal
governor and it comes under the category
of loaded governor and here we have
deadweight which is kept when we compare
Proell governor with Porter governor
which we have seen just now in Porter
governor the flyballs
they were connected to directly at the
intersection of the links now in case of
proell governor the flyball is extended
upwards so as I have told just now that
the working principle of the governor
remains same only differences in the
construction of the parts so here what
happens again I would be explaining that
when the spindle speed the spindle of
the governor it rotates at a very high
speed in that case the fly ball they try
to move out now in this case they would
be moving out and in this manner that
they would be moving out in this manner
the fly balls they would be moving
outward since they are connected it
would be moving in this manner and when
the fly balls they are moving outwards
the sleeve it moves upwards and then the
fuel supply is reduced and what happens
when the speed decreases when the speed
decreases the fly balls instead of
moving out because the centrifugal force
now would be less the fly balls they
move inside and when they move insides
the sleeve is pushed down and the
surface over which we are supplying the
working fluid that passage it gets
increased so in short what we have
understood about royal governor is that
Pro is a Warner is a centrifugal
governor
it is a centrifugal governor and the
type is it is loaded governor where we
are having deadweight and it works on
the principle of scientifical force that
is as the speed of the engine increases
centrifugal force will try to move these
balls outwards fly balls will be moving
outwards and it would be moving in such
a fashion about this link fixed link the
fly balls would be moving output and
when they are moving outward the sleeve
gets lifted the passage the throttle
valve closes the passage here as I have
explained in the diagram before also
so now as the speed of the engine
increases flyball move out slip move
upward when the sleeve moves up this
passage gets blocked that is the
throttle volver it will try to
straighten in a horizontal plane it will
block the fuel supply and when the speed
of the engine is decreased
flyball they move inside sleeve is
pushed down and this throttle valve it
tries to be vertical that is the passage
is open and more amount of fuel is given
to the engine to maintain the constant
speed so as we have seen in case of both
Porter as well as royal governors they
control the supply of working fluid to
the engine and by controlling the supply
of working fluid to the engine the speed
of the engine can be controlled so this
was regarding prowl governor
seeing it is called as Proell governor
proell governor is also a centrifugal
