Hi guys

Here is another idea for anyone contemplating the design of a new and different motor.  :doh:
Comments would be appreciated.

Edit:
Initially the subject was "New 4 Stroke - Without Valves". Bernd made the comment about conventional valves so I edited the subject to
"New 4 Stroke - Without Conventional Valves". That is why Bernd made the comment that he did.
I hope that I have everyone thoroughly confused. I know I am. :lol: :lol: :lol:

Bernd:
Very interesting Don. I don't think you can call it with out valves. Without conventional valves maybe. Looks like the two smaller pistons act as valves opening and closing on a port.

Hi Don

Quite novel. But, as he seems to have been working on it since 1980-ish., I don't think it's going anywhere.   :(  particularly as we seem to be going electric ....

It seems to be a popular pastime with some humans to seek a better solution to getting stuff in and out of I.C. engine cylinders, yet ... we always come back to the poppet valve.

I have a book entitled 'Valve Mechanisms for High Speed Engines' .. full of stuff on the subject. Practically none were ever successful except the sleeve valve.The Cross and Aspin rotary valves showed promise, but had lubrication problems that were never sorted it appears. None about now AFAIK . 

(Seems the book is quite valuable   :D  :D  I got mine for £0.50p years ago) .

Of course mine is even more valuable, on account of it's exalted owner ... :lol:

Leave it to my nit-picking that's cause the confusion.

The reason I say "without conventional valves" is that everybody knows what a valve in an IC engine looks like. To my way of thinking, and it may not be presice, is that something that opens and closes a hole or port is sort of a valve. You are controlling the intake and exhust of a gas or liquid.

Pretty neat, Don.  I think your original title is appropriate.  It doesn't have valves, it has ports.
Bluechip saw just what I did when I first saw this.  The poor guy is working on a better mouse trap at a time when people no longer want to catch mice.  ; )  Just bad luck, I guess.
