Walschaerts Valve Gear Cut Model 

CUANDO UNA PERSONA COMÚN COMO YO, AL VER ESTOS MODELOS EN CORTE COMPRENDE EL PRINCIPIO DE FUNCIONAMIENTO DE ESTOS MECANISMOS AL MISMO TIEMPO COMPRENDE LA GRANDEZA DE LOS GENIOS QUE LO IDEARON.

Great video thanks for sharing. The Combination link is not integrating the 2 movements. It is only supplying the Radius Rod movement. To fix, the upper pivot of the Cintrol Valve needs to be positioned near the upper 5% of the Union link (lowered slightly) so that the 2 input movements can be summed. Currently the lower link is having no effect.

Comments are of course correct in observing that the combination lever here is ridiculous. But the return crank leading the main, which some have queried, is correct, because this model uses a D-valve, which has to have live steam on its outside, keeping its face pressed down. The crank trails the main in most of the locomotives that we have grown familiar with only because they all employ piston valves, which have live steam in between the valve pistons ['inside admission', as opposed to 'outside admission' here]. They don't HAVE to, but usually do because this reduces leakage waste past the valves and through the glands.

Fun fact: The combination bar in this video does exactly nothing. It is better to be removed to reduce clutter and confusion!

Thanks for an excellent demo.

Genijalno!!

Excellent demonstration showing internal movements I’ve always wanted to see how these monsters harness their power and the purpose of all the arms rods linkages valves. As far as the direction Fwd or Rev that’s immaterial the basic movements will appear the same to someone like myself great display!

That is great! Just a suggestion, maybe you could blow smoke into the model, that way you could see how the steam works.

Exactly best idea for growing humanity

Спасибо!

brilliant engineering

Passionnant Ont ne lasse pas de ces pie es d'orfèvrerie mécaniques*****

Thanks, great vid.

J'ai beaucoup aimé le design👍❤

Thanks!

super video..................

justandy333--that is correct. And it is 'exhaust pipe' the smoke stack of a locomotive. FS2K4Pilot--it depends on whether the valve is inside or outside admission.

There seems to be something wrong with the set up. The rod from the expansion link isn't supposed to connect directly to the valve is it?

Very Nice, Thanks. ¿What role does the combined bar in this steam engine?

Have I got this right? The high pressure steam would be coming from the red area above the horseshoe shaped valve. As the valve moves to the left, the right hand side tube is opened to the hot steam and it rushes in to move the piston along the cylinder. But simultaneously the left hand side tube is connected to the exhaust pipe (whatever its called) and the coolish steam is forced out the exhaust pipe by the piston. Then as the valve shifts, the cycle is repeats on the opposite side?

Ya podre morir en paz😄 ahora que se como funcionaba

Great work building this model, but it seems to me there is something wrong with the way the combination bar is hooked up. It seems to me it would do nothing in this configuration. It needs to have an offset between the radius bar and the valve stem. See this link for more info. en.wikipedia.org/wiki/Walschaerts_valve_gear

The flying crank should LAG a quarter turn behind the main crank, not lead it. Your engine is thrown in reverse, in other words, the wheel should be spinning counterclockwise for this model to be correct

neet!

Oh my ! That was almost naughty to watch, especially at the 0:52 mark !

Sooo nice

Cool !

무슨 물건 인가요?

Where can I purchase this model?

Free energy, whooaaaa

I think your eccentric crank is backwards.

Qué tipo de máquina o motor es ese

Hello. What would the piston in the steam chamber be made of, that is, the one that produces the mechanical work?

What’s the function of the link bars between the crosshead and the valve gear. It seem to do nothing but go along for the ride?

Good

Is it okay to assume that steam is sent from the tube that looks small on the left?

Чётко и ясно!

good👍🏻

It's running full speed in reverse.

On the part where it is sped up its actually running backwards :(

BRASIL OK.

Interesting that they used a slide valve rather than a piston valve....

How it's different from steam engine?

Cool 😎

cara mendowload

Cuál es la enseñanza que nos quiere dejar con ese vídeo

Perfect explain

Walschearts　⇒　Walschaerts

Are you able to send this what is the price

How did they get a video of me in bed????

What's the rate of this.

👍👍👍👍

Pls make slow motion video

🔥🔥🔥🔥🔥🔥🔥👀

Iove..u..Fc

Where to be purchase send address.

Depois a bosta da minha professora vem dizer que sociologia vale mais que engenharia. Só a conta para desenvolver essa braçagem vale mais que a vida de Karl Marx hahahahahaha
