Whoever cut that piston up is definetly going to at least Dante`s 6th circle right off the bat.

Whoever cut that piston up is definetly going to at least Dante`s 6th circle right off the bat.So, yes, a Jumo 222 A/B piston. I never thought I would see one but, this was advertised a few years ago without identification and I bought it. You might not be able to read all the stamped info on the face but the long line says, 222.242 001 f FLUG-ABT.IFA- xx
That is the Junkers part number, followed by a small f then the aircraft parts works abbreviated name. The marks x x are a Junkers symbol with the number 53 which is a Junkers QA stamp, and a lozenge shape with the number 17 inside which is a BAL ministry approval stamp. The weight 1253 (grammes) is stamped at the top and the machined finished size of 134.74mm is stamped on the LH top face, but difficult to see on pic. These pistons have a mirrored pocket for the large single exhaust valve edge because some of the cylinders had exhaust on the RHS, some on the LHS.
The engine was a 2,500hp class but, it never made production, despite possibly being ready, or politics stopping it. The A/B engines were discontinued from development in about 1942 and it is likely that they were all reduced-to-produce. I do not believe a 222 A/B exists today, although there is a later one in the museum at Munich.

I agree it looks like a hot air valve, not a throttle valve, possibly a bleed air valve off a Jet engine, or a heated air valve for an anti icing system. Did any German WWII A/C use heated leading edges for anti icing?So it looks like Tomo and special ed are interested in this piece? Maybe they would bid? This is all I had to go on, and the pics were less clear than these, if only that number had been clearer! It certainly is an airflow control butterfly valve but, it is not a carburettor and the size is over 4in dia. Does it look like any German WK2 Luftwaffe engine induction pipe we know? I thought it looked familiar, so I looked at a few German aero engine pics online..
Anyone guess?

Indeed it does cammerjeff. However, what if I tell you that this part possibly took part in the Battle of Britain!I agree it looks like a hot air valve, not a throttle valve, possibly a bleed air valve off a Jet engine, or a heated air valve for an anti icing system. Did any German WWII A/C use heated leading edges for anti icing?

I have no idea but keep on searching.To fill in a bit of info seeing as this thread is slow, This type of submerged electric fuel pump seems to have been designed by the Deutsche Benzinuhren G.m.b.H (DBU) company of Berlin. They were then made by several other companies as they were used on many German aircraft types. They have an approx 6 inch long sealed 24v DC electric motor in the bottom end and the pumping element is a small approx 2cm dia scroll impeller at the base. Fuel passes up a central tube and out of the 90 degree union at the top. The static pressure generated is only about 0.3kg/cm, maybe 5psi and the flow rate is moderate. I am interested if anyone has any experience with these pumps and what aircraft is my pump from?

Yes, but do not worry, all can be revealed!I have no idea but keep on searching.
That can be included. However, I am not seeing any other offers about this/these pumps yet..Droptank related?
