The end in question might be a pressure relief valve to prevent it getting higher than atmospheric or some figure close to it.

The patent was easy to find but people seldom give working model type instructions in patents

To avoid duplication:

The book linked in my post here, has some useful description.

Incidentally … This modern patent, by Philips, cites Robinson and several other early patents.

Depends on who's model you look at all the Alyn Robinsons had the valve and regenerator

There are 2 video's by Phillips on youtube showing where they got with their engine. It can be seen liquefying air when it's driven backwards.

The patent does mention the "governor" Fig 11 and also Fig 8 which looks more like it might work.

The Russian link is interesting from a modelling point of view.

Slight digression:

More books by Kennedy, Rankin d.1917 are available:

Thought I had it tucked away somewhere, this is the section through the Alyn Robinson engine which is a close representation of the full size, you can see the valve, wire wool fille dregenerator and all the properly cored passages unlike some models that you have to drill achieve the same effect. Graham had/has access to a lot of full size engine so his models are true to teh originals.

I'll ask Graham and get back to you.

Edgar Westburys Robinson Engine has issues and an interest fix article was printed in ME3467 which budding builders may find useful in their own build

Thanks Ady. That's of great interest to anyone thinking of designing their own. The more they are gone into the worse it gets so clues always help.
