good show to you guys and i like to thank is mekanizmalar

Thank you very much for this display; wonderful. I'm building a 4-4-0 Virginia as per LBSC's book. I am not a machinist and have rather modest equipment: vintage lathe, stand mounted mill-drill, several files and all materials are gleaned from junk. I was hung up on just how I could most easily mount the valve crank. Your working drawing and some photos I took of some modern locomotives have made me confident that I can satisfactorily accomplish the task. I'm hopeful that I will be ready to start building the boiler shortly after the first of the year, 2013. My locomotive is in 7 1/2" gage. Thanks again Dan Manley.

I want to download this but i can not.help me please...

not true of British Great Western design which had external cylinders but internal valve gear on the larger locos (Castles, Hall, Kings etc)

Nice animation. Only that the reverse motion is incorrect.

Any chance you could add the components that cause the link block (British: die block) to slide up and down in the link (british: expansion link)? These would be 1) engineman's reverse lever, 2) reach rod, 3) reversing shaft (end view), 4)reverse arms and 5 hanger. I could attach a diagram to an email to label those parts for you. It would be wonderful, because then it would show not only how the engineman reverses the locomotive, but also how he can shorten the back and forth travel of the valve o cause steam supply to the cylinder to be cut off earlier in the piston stroke to save steam and use the expansive properties of the steam (= to extracting more of the thermal energy in the steam before it is exhausted) I suppose that I'm asking a lot! I could attach diagrams showing how shortening of valve travel influences the timing of the four primary valve events: admission, cutoff, release and compression. In any case, congratulations for a great animation!

PS--I just LOVE it that your animations can be SLOWED DOWN. Far too many animations on the Web go too fast for a viewer to get a good understanding of how it works,

you cant download it.....but u can use snagit screen recorder to record the animation and save it..

حقاً إنها لعمل رئع يسهل الشرح و يوضح كافة المعلومات عن البخار، وسير الحكة به و كيفية تحويل طاقة البخار لعمل ميكانيكي مفيد ... جزيل الشكر لكم

THANK YOU SIR.
It is wonderful work the steam engine animated, and eases description.
How we can changing the steam to do make machines useful.

This is neat
