So when the piston gets sucked upwards, the other valve is still sucking it upwards. Not pushing down or something, so it forces the piston to remain in the upward stroke. Am I right?

To my understanding you need a exhaust valve, so that the vaccum can suck in air so the vaccum cleaner has something to suck on. Also i found to have the best result with vaccum engines that instead of taking those plates as valves you need to use the tires from the Speed Champions cars because of the rubber, the valve has a better seal.

tysm for including me in the video!

gotta love it

This is really cool, but as a somewhat experienced vacuum engine builder, i should tell u that a 6x6 piston is quite inefficient since a larger volume of air has to be sucked in by the vacuum then in a 4x4 piston. Also having 2 valves technically doesnt reduce efficiency but your valve design isnt the best because the valves dont let the piston go down freely enough cause of the way they are designed. Hope this helped lol

awesome ! you could try a different flywheel like a ligth and at the same time heavy but keep working you're doing great vids👍

that's a pretty cool design, I also made something similar, well similar to vacuum powering a lego engine, except mine was based on a steam locomotive piston, like where you have the valve that goes back and forth switching from one side to the other, it worked quite well, sadly it had no way to reverse the direction.

Nice bro

Hi, Not long ago I tried using this model as a base starting point for a vacuum engine. I found that you need to have 1:1 crank to cam ratio and also an exhaust valve. Also you should use a little bit of olive oil on the cylinder walls and valve seats to lubricate and seal components.

To improve this alot first make sure both ports aren’t connected, you could also just do a 1:1 gear ratio from the crank to valves, lastly seal the valves off from the crank and make try to make a spring set up for the valves

YES FINALLY!

You should call it the bricks and Stratton

You probably should make a rotary vacuum engine,they spin very fast and are compact,also you don't need a flywheel. You could gear it down as well.

@DeltonAdamsLEGO

Ай бұрын

Yeah, but I think sealing it would be hard for me

Pretty cool the one idea I had was plumbers tape for the air leaks it should be thin enough that it doesn’t affect the Legos and would definitely help create a seal and without damaging the Legos that’s a bonus keep up the hard work👍

@DeltonAdamsLEGO

Ай бұрын

That's not a bad idea!

Nice

instead of using the 2 by 2 tiles as intake and exhaust valves, use a piece like Lego piece 2723 and it will work better. Also idk if this will work but Lego tires may fit on the disk thing.

it is possible I KNEW IT goooooooooooooood job btw

Try making one of the valves putting in fresh atmosphere to not starve the cylinder of air, and try and counter balance the piston. You'll notice when it runs, it speeds up when the piston goes down and slows down when the piston raises

@DeltonAdamsLEGO

Ай бұрын

Yeah, I probably will if I come back to this

you need 2 valves running at a 1:1 ratio to the crank and 180 degrees apart, should run like a compressor in reverse

Funny thing I have one of those motors

Instead of the tiles try the black round technic disc thingies that nobody knows the name of that are commonly used for LVE poppet valves. And it will run better as a "2 stroke" with 1:1 gearing for the camshaft but who knows, maybe it will work as a 4 stroke (with the cams offset 90° and both intake and exaust happening every other rotation.)

We need to seeca Ali express karge super chelarger works? Can it be super cgarged with for stage.😅

the problem is you need to have one of the valves for air and it might need to be quite big considering the size of the piston

You had 2:1 gear ratio with cam lobes 180 degrees apart and intake connected to the exhaust. You need to have 1:1 gear ratio and make independent channels for valves :)

@DeltonAdamsLEGO

25 күн бұрын

Yep! I'm working on that now!

usually when pp convert briggs to steam they add another lope on the cam or change the ration of the cam to 1:1 to your intake valve open when your piston go down and exhaust open when it go up , vacuum engine are reverse steam engine, so either change the ratio or the cam lope to be 180 deg so like you have to piece for one lope just turn one off them 180 deg on each lope and but you vacuum on the exhaust side
