Oh wowi!

Something new! Very neat design. Wish that scan was clearer and complete so I could read the whole article. Also it could be put in our archives!

It has the same principle as axial piston hydraulic motors and pumps. Hydraulic pumps and motors have an odd number of pistons though... 5, 7 or 9 usually, to make sure it will start every time.

Never seen an internal combustion engine with such a layout Huh...

It has been done before, engines using the wobble plate principle as in hydraulic motors or pumps were around even bofore the war. I had a look in my ancient vintage car magazines: On the 1948 Paris motor show, people could discover the REINE 1950, a revolutionary car made by Mr Brandt with a little cumbersome wobble plate engine.

Wow, looks like a two stroke with counter-pistons Very Happy

All kinds of strange things have been conceived in the past. I do remember reading about a Profi type engine, I think it was a single cylinder engine where the piston went back and forth inside a rotating cylinder Huh...

The article is by Dan Sitter. Isn't that California Dan on eBay? Or do I have some names mixed up?
