Michael Hiles Posted May 18, 2013 Share #2 Posted May 18, 2013 Looks like some kind of pump. Link to post Share on other sites More sharing options...
Karl G Posted May 18, 2013 Share #3 Posted May 18, 2013 I agree with Michael's guess and add that it may be a gas pump, aka a turbocharger. Link to post Share on other sites More sharing options...
luigi bertolotti Posted May 18, 2013 Author Share #4 Posted May 18, 2013 Not a pump... nor a turbocharger/compressor. My hint about the "non trivial technology" is related not so much to the dimension in itself... but specifically to the device in itself... Link to post Share on other sites More sharing options...

Michael Geschlecht Posted May 19, 2013 Share #6 Posted May 19, 2013 Hello Luigi, It looks like it might be some sort of hydraulic device. Perhaps related to steering or braking? Best Regards, Michael Link to post Share on other sites More sharing options...
pauledell Posted May 19, 2013 Share #7 Posted May 19, 2013 Advertisement (gone after registration) Luigi, I have never seen something like this, but could it be an electric motor or generator with the openings at the top for connections and the machined coupling on a shaft? I may be barking up the wrong tree. Paul Link to post Share on other sites More sharing options...

sebastel Posted May 19, 2013 Share #9 Posted May 19, 2013 it's a rotating piston motor, after its inventor named "wankel". this engine is supposed to be used in a model airplane. but not in the current status - needs a thorough cleaning, and a check of bearings and internal surfaces.

YOU GOT IT A Wankel engine for aeromodels : made by Graupner... probably the one firm that makes such engines for models (developed jointly with Japan's O.S.) I am not a hobbist in this field.... have found it at a flea market for few Euros and bought it just for its oddiness... at the moment, I haven't yet succeeded in opening it... ... screws seem blocked... but I will try better : the inner part must be very fun to see...

Right, Luigi : I used to be a practitioner of aeromodelling - and even a champ - before flying bigger things, and I saw various versions of the tiny Wankel engines: Their problem : weight versus power. One of my brothers in law had a Wankel-powered NSU car for some years. The rotating "piston" of the Wankel engine is triangular. Link to post Share on other sites More sharing options...

Just for curios... did you use the engines made in my town ? (Rossi - Novarossi , I know them well... their engines won, and still win, many championships all over the world). About Wankel... my father did use, for few months, a NSU RO 80... Wankel dual-rotor (NSU made also a small spider - monorotor) : not a succesful car, even if it had a very modern styling for those times (end of '60s, iirc) Link to post Share on other sites More sharing options...

Mines were OK, ED-Bees, McCoy (and a heavy French one whose name I cannot remember now), both gow plug or diesel. I agree with you that the RO 80 was attracting attention...and problems.

daniel88 Posted June 30, 2013 Share #14 Posted June 30, 2013 It looks like a pump or compressor of any machine. I am not shore about it but it looks like motor ump. Link to post Share on other sites More sharing options...
pauledell Posted June 30, 2013 Share #15 Posted June 30, 2013 It looks like a pump or compressor of any machine. I am not shore about it but it looks like motor ump. Believe it or not, I ran across an old motor in my years at General Electric Co. Motor division in the design engineering that looked somewhat like this and it was related to a pump design. I have no doubts that it is what Luigi says it is. Paul Link to post Share on other sites More sharing options...
