    Hi all .just after a bit of information on the subject i have done all the hard work restoring the hot air /Stirling engine built new displacement pistion and power pistion conrod tubes and bearing adjustment rods and new leather seals for both cylinders and built a new water pump from new carstings .i have most of the pipe work sorted out but there is one pice of plumping i can not find any information on .Its on the back side of the power cylinder just above the flange where the top cylinder bank is bolted to the bottom water jacket by sum of the photos i can get a hold of it looks like a one way valve or a vacume or a presser regulator venting to atmosphere. Any help will be extremely appreciated if photo's are wonted just ask

    Here in the UK we have this year finished restoring a Hayward Tyler hot air engine built under Rider patents. This engine has a one way valve connected to the bottom of the cold cylinder. It's simply a weighted metal valve with metal face resting on a metal seat. Its acts to let air into the engine if the vacuum generated by the cycle becomes too high. This happens if there is leakage though the seals when the piston is driven up on the power stroke. Our engine when working lets a little air in on every cycle as we still have some small leaks from the leather seals

    The hot cylinder crank is in advance of the cold crank by a little more than 90 degrees , probably nearer 100 but I haven't measured it ... On our engine it is keyed and cant be put back wrongly

    Thanks for that mate. Found out that the crank shaft was twisted out of position dew to previous owner trying to turn the engine over while both cylinders where seized
    Thanks for you help
