Why throttle valve is used instead of expansion cylinder in vapour compression refrigeration system?

In vcrs system there is a phase conversion system i.e. liquid state to gases state and this happens with latent heat of working medium but on the other hand there is only gases expansion on expander cylinder and no phase changes occurs and in cylinder we can not expend two phase system..

Why do we use throttle valve in steam engines?
For a steam engine, the steam(throttle) valve that sets the engine speed/power is often known as a regulator. k.Shiva
What is the working principle of the governor?
Power is supplied to the governor from the engine's output shaft by a belt or chain connected to the lower belt wheel. The governor is connected to a throttle valve that regulates the flow of working fluid supplying the prime mover. As the speed of the prime mover increases, the central spindle of the governor rotates at a faster rate and the kinetic energy of the balls increases. This allows the two masses on lever arms to move outwards and upwards against gravity. If the motion goes far enough, this motion causes the lever arms to pull down on a thrust bearing, which moves a beam linkage, which reduces the aperture of a throttle valve. The rate of working-fluid entering the cylinder is thus reduced and the speed of the prime mover is controlled, preventing over-speeding.
What causes clutch judder when engaging gear?
There is one cause for this. If the throttle body is moved or adjusted in any way this will cause the judder when engaging gears.
How working the governor during steam turbine operate?
governor senses the speed of spindle of engine and controls the mechanism of opening and closing of throttle valve
You have miller welder powered by Tecumseh engine there is a system that advances the throttle when an arc is struck is this part of the engine or is it an attachment from the welder?
its part of the engine but works in conjunction with the PC board.
How do you do a compression test on a car engine?
Remove all spark plugs.Insert compression gauge in cylinder #1Hold throttle open and crank for 5 seconds.Record reading.Repeat on all cylinders.Remove all spark plugs.Insert compression gauge in cylinder #1Hold throttle open and crank for 5 seconds.Record reading.Repeat on all cylinders.
What is compression per cylinder for jeep wrangler 2.5l?
Should be near 100 psi with all plugs out, throttle open, and a fully charged battery.
How can you tell if you have a compression leak?
Do a compression test Make sure battery is fully charged Remove all spark plugs Lock throttle fully open Check each cylinder Highest should be within 10% of lowest
25 hp mercury runs slow at full throttle whats wrong?
check the compression. might have scored cylinder. also can be found by pulling plugs the scored cylinder is the one with the burned plug. fouled plug?
What is the compression ration on a 1991 camaro rs 5.0 v8?
The lowest reading cylinder should not be less than 70% of the highest and no cylinder reading should be less than 689 kPa (100 psi). Perform compression test with engine at normal operating temperature, spark plugs removed and throttle wide open
What is the compression psi in a 95 s10 pickup with a vortec v6?
The lowest reading cylinder should not be less than 70% of the highest and no cylinder reading should be less than 689 kPa (100 psi). Perform compression test with engine at normal operating temperature, spark plugs removed and throttle wide open.
What is the compression psi of a compression ratio of 16.2?
There is no direct connection between compression ratio and pressure. Ratio is a mathematical calculation of the cylinder volume from bottom center to top center. Actual cylinder pressure will depend on the volumetric efficiency of the engine. Factors the affect volumetric efficiency include rpm, intake design, throttle plate size, amount of restriction in the exhaust, size of the valves, shape of piston and combustion chamber.
What is a cylinder injector?
It's direct injection, under compression as is used in diesel engines. Most automobile injectors are either throttle body (sort of like a carburetor with one or two injectors serving all cylinders) or manifold injection with an injector for each cylinder.
Where is the throttle sensor on 4 cylinder Hyundai?
The TBS or "throttle position" sensor is located near the throttle body on the linkage.
What is the cylinder compression of a mercruiser 7.4 mpi engine?
MY Mercruiser 502 8.2L V8 between 133-155 pounds pressure dry, not warmed up & throttle at idle instead of wide open throttle. I was comparing the difference between the cylinders seeing if anything was obvious bad... Warmed up... Open throttle valve will give you a higher reading.
Where is the throttle positioning sensor on a 1989 Oldsmobile with a 2.8 Liter 6 cylinder engine?
The throttle positioning sensor is located in the throttle body.
Why does the engine choke at full throttle?
The motor chokes at full throttle because either the exhaust valves are bad and cause the motor to loose compression at full throttle or the carb has an air leak.
