This is what I call art. Being able to build a purely pneumatic engine with stuff you have, now that's it!
Wonderful!
Appreciate your Efforts
Ottima idea 🧤
Super
That’s pretty neat. From the look of it I’d guess making cam profiles with a bit longer duration might improve output.
Good observation :)
That would be true if i had used a common spring returned valve.
However in this case I used a special pulse-valve. Those just need a short pressure impulse to switch position. So they stay in that position until the other control valve, which is actuated by the cam, provides a short pulse to the other side.
@@jonny999 Interesting. Thanks for the reply.
Very nice and new thought
thanks
haha gute idee mit den nocken zum umschalten^¹
danke^^
Für diesen provisorischen Aufbau perfekt und mit den Kontermuttern sehr einfach zum einstellen :)
Very good for the pneumatic system. regards
Thanks!
It is not that complex though :)

Compressed air is the most expensive form of energy
Compressed air is not expensive, but clean compressed air is not cheap to produce
@@luanminh8887
Leakages
The most expensive are fossil fuels they're costing us the earth
If that, Pneumatics wouldn't be a heart of automation
@@luanminh8887 Pneumatics are really inefficient and expensive energy wise with a energy efficiency at about 10% or so with a leak tight system, and on top of that it requires a quite expensive system with compressors, dryers, filters etc.
It is used in automation a lot is because it is a type of energy that is easily controlled and the pneumatic components are relatively cheap and very robust.
Appreciate your effort. How much RPM and torque can it attain?
Base idea. Pneumatic energía is 7 times more expensive than electric. By the other hand, the force is not constant
You are totally right!
That's why it stayed a test setup, with no practical use :)
Wait for the burst cylinder do not stop
Es mucho más económico un motor eléctrico.
Impresionante
I'm glad that you like it :)

Thank,s.very nice.
Hy
Sind das Drosseleinschrauber im Zylinder oder Schnellentlüfter,
oder hast du die Abluft übers 5/3 wege Ventil ablassen?
lg
Am Zylinder sind nur 2 Drosselrückschlagventile (zur Abluftdrosselung) und die Abluft geht letzten Endes wieder durchs 5/2 Wege Ventil... Stimmt! Schnellentlüfter wären ja optimal gewesen fuer diesen Zweck :) Wozu sollte man hier die Geschwindigkeit drosseln wollen xD
@@jonny999 Wo gibt es solche Zylinder und den restlichen Zubehör zu kaufen?
Kannst du mir ein gutes Buch mit dem dazugehörigen Wissen empfehlen?
Vielen Dank für deine Antwort

I think , If It have the flywheel for balance shaft ,It will not have the vibration happen.
Good idea, that would have improved it!
Sorry ,I think tell name its wrong ,it is not flywheel ,but Its name is "Crank shaft balance mass" ,and it install on the shaft in opposite direction with the connect joint of the connecting rod ,and sure if you install ,the machine will be smooth.
Yes, i already thought you meant some kind of balance mass :)
@@santikaewshalauy5551 its flywheel, right said.
@@santikaewshalauy5551 its enough a mass of steel can be completly round, its spinning momentum will help the shaft to turn
Nice may i know how u decide the lengt that connecting from shaft to cylinder, becaus i try to use the formula full stroke of the cylinder devided by 2 equal to the length the connecting shaft is it correct? because when make a turn its stuck either to upside or downside cannot make a full turn. Hope u can help me for my project.
Yes, that is correct. Half of the stroke is theoretically the optimal length of the "crank" (center of shaft to cylinder rod). But you would have to arrange the mounting of the piston very precisely.
Anyways i made it a little shorter (in my case about 4mm, so i have 2mm tolerance) to ensure that the stroke is enough for a complete rotation even when the Cylinder is not aligned perfectly.
Muy bueno
Hi jonny, I'm new to pneumatic. Could you pls tell why you inject air to the bottom and the top of the piston instead of the bottom only? What is the black component on the left side of the regulator? Thanks!
Hey, thanks for the comment!
There are two different kinds of pneumatic cylinders: single-acting cylinders (returned by a spring) and double-acting cylinders (which i am using).
With this type you can regulate the speed much better, and it has more power, because i can extend (bottom hose) and also retract (top hose) the piston with air pressure.
The component i use to adjust the speed in the video, is is a pressure regulating valve (it controls the input air pressure).
The little valve right next to the regulating valve is a throttle valve, with which i could adjust/limit the air flow.
The big valve in the middle is a 5-2 way valve which obviously actuates the cylinder^^
If you have any further questions let me know :)
@@jonny999 Thanks a lot Jonny. Clear enough for now but I might have more question in the future. Can I get your email or can I dm you in that case? Thank you
No problem :)
Sure, you can contact me anytime!
Btw. if you are interested you can always find more information about my projects on my website: pfusch.zone
Instead of using compressed air, can you use a vacuum setup? Because I came up with an idea about a year ago and I would like to see if a vacuum pump would run this setup
Hm, with this setup it will not work, because the particular 5/2-way valve i used needs pressured air to operate / switch position.
It might work with an non servo-assisted solenoid valve, or a mechanical operated one.
But i think it wont have much torque or wont move at all, because the maximum pressure difference would be 1 bar (air pressure).
Anyways, i could try this some day with my vacuum pump ( czcams.com/video/yNwU6VII_GI/video.html )
How would you get/generate the vacuum?
This video might interesting for you: czcams.com/video/yNwU6VII_GI/video.html
I powered a drill with vacuum there :)
@@jonny999 I was thinking for testing use a vacuum pump but ultimately it could be utilized for space. If it works. Could you PM me via email? My email is andrewjh93 at gmail dot com
Now use a refrigeration cycle to renew your air supply .
Best product
very nice
How to design the crank. What is radius of crank
The optimal radius of the crank (distance between the center of the holes) is half the cylinder stroke.
I made it a little (~2mm) shorter, so i can ensure that the piston is still able change it's direction while keeping the direction of rotation, even if i don't mount it very precisely to the base plate.
In that video you can probably see it better:
czcams.com/video/1WrR04NSUsM/video.html
It look best for fun but not suitable for practical purposes
What are the applicationa of this cylinder???
This "Engine build" has no use for any application, it simply was a fun-project :)
The cylinder itself was previously installed in a production machine.
In my second video it powers some devices, to demonstrate the torque:
czcams.com/video/1WrR04NSUsM/video.html
Similar application with pneumatic motors are used on non spark enviroments...
Это что за штукенцыя такая анжинерной конструкции?

Awesome
lovely engine marvellous please tell me can this penumatic cylinder work on steam?
Basically this is a steam engine. Quite similar to the kind used on steam locomotives. The only difference is that he is using compressed air instead of steam.
May i know how your device works? I am currently trying to understand how it works.
If you follow all the blue hoses, you can see that the 5/2 way valve (in the middle) controls the pneumatic cylinder.
The two 3/2 valves (on the left), which get activated by the rotating shaft at certain angles, are connected to the 5/2 way valve.
So depending of the position of the crankshaft the 5/2 valve switches position and the cylinder extends or retracts again.
jonny999 Did you modify the pneumatic piston? I think you did
What do you mean?
I only attached a crankshaft to the piston rod, and a screw on the other side to hold it in place :)
@@jonny999 may I know clear details about that valves??
Do you want me to explain the valves i used?
The main valve which controls the cylinder is a "Bistable 5/2-Way-Valve controlled by air pressure"
That means it has 5 connections, 2 switching positions/states and it gets switched by air pressure.
Bistable means that a short pressure impulse is enough to switch over the valve and it stays in that position.
The 2 small valves at the camshaft are "Monostable (returned by spring) 3/2-Way-Valves controlled by roller " they let air through as long as the valve is pressed by the cam. This air impulse then switches the main valve.
In my new video are some closeup clips and pictures of the valves:
czcams.com/video/1WrR04NSUsM/video.html
On that site you can also find a pneumatic diagram (this might help to understand the valves):
pfusch.zone/pneumatikmotor/
hey is that a 5/2 valve that u have used??
Hey, exactly! I used a 5/2-way valve, pneumatically actuated (by the two 3/2 valves)
Do you think i can build a two cylinder engine with an additional valve? :D
this is a compressed air motor I have one but mine make 4 rpm in 1 sec ,ok mine piston isnt so heavy than your machine I see that your motor have much force than my motor I like the neumatic sistems bye
At last it get friendly environmental exhaust
how to make that
Молодец
Very well bro
Una pregunta,si el pistón estuviera derecho al eje central no giraría más parejo en velocidad?
What do you mean with the piston being straight to the axis / how could it be done?
The cylinder always has to swivel to counteract the alternating height caused by the crank.
@@jonny999 digo el cuerpo del pistón en el centro de giro para que el ángulo de fuerza sea iguales en el empuje
Me refiero al centro de giro del pistón igual al centro de giro de la manibela indistintamente del ángulo del pistón
Me refiero a ángulo de ataque del brazo de palanca?
It is good job! Could you send the pneumatic diagram of the unit please?
Thanks, i uploaded a pneumatic diagram on my website!

How would the diagram be in the Festo program? :)
I actually created a diagram with Festo-FluidDraw some time ago :)
pfusch.zone/pneumatic-engine
Its one of the last Images on that site.
Hallo, wird der Zylinder komplett ausgefahren? oder wird er vor'm anschlag "zurückgepustet"?
Und er fährt auch nicht komplett ein oder?
Ja genau, das Ventil schaltet jeweils ganz kurz vor den Zylinderendlagen (Anschlag) um.
(also eigentlich genau nach Position der "Kurbelwelle" durch die Nocken und Taster)
Super, danke für die schnelle Antwort :)
ممكن واحد يشرحنه إليه العمل
Awesome😂😂😂
A idéia é boa, mas a vida útil deve ser mínima
only timer enough.
hi jonny999. could you tell me (list) the parts I need to make an engine like yours? the name of the parts? thank you
It's a big pneumatic cylinder, a solenoid valve some tubing an air pressure regulator, an air compressor, and the rest are custom parts
A detailed list of parts i used can be found on my website:
pfusch.zone/pneumatic-engine
There are also some sketches of the custom parts.
please make video on that how to make...
You can find some pictures of the building process of a similar project on that site:
pfusch.zone/pneumatic-engine
I think there is not much more to explain, the pictures should give you some ideas of how to make it i guess :)
很酷的東西，但為什麼呢？
Just needs a flywheel
Для чего?
It has no practical use, it was just a test :)
Even if you could use Hydraulic piston will not work out! The hydraulic motors already some, company using in their skid type excavators !!!! for skid purpose only ! not...." on road fast drive !!!!" Also in 1983 myself set up the hydraulic type motors in Saudi Arabia, yanbu refinery city. Tested in front of Royal commisson officials . it given high torque slow drive !!!
เพื่อ?
i want some idea with the timing. can you please help with it?
email id ?
Sure, i can give you some tips :)
Are you building something similar?
*Please send me a PM.
