Twin Rotary Valve Engine

Hooray, it's running! Another success, well done - these designs are getting more interesting each time

Cheers Sanjay, I think it could be made much more compact and use a lot less material though.

Hi Paul,


The engine runs well. It could also be used as a pump if a water pump were attached to the protruding piston rods.

Thanks Michael, it does seem to have a fair bit of power so a pump might work. I fixed some leaks and gave it a coat of primer but it still needs some sanding around the wonky pipework  It was running on less than zero on the compressor's gauge before I took it apart so it needs more running in. It's also got bit of St Vitus's Dance!

It hasn't got a coat of paint or a proper stand but as it was another experiment and I'm short of time I'm done with this one. At least it works ok
