Hello John
Thank's for the last photo and your answer ! It explains everything , and I learned something new .
The IP diaphragm is only sealed to the main body by the IP pressure .
Why not . As not fixed on the outer diameter it has much more freedom to move without to much stress . The IP goes through the piston and thin trandverse bores to the IP diaphragm . The funny thing is that the IP is gained near the IP outlet . Looks like a IP venturi system . If the sealing between diaphragm is good it is a exellent design .
Thank's JB for the great photo !
For you as an artist it may look ordinary , but for the technician it's looking great .
Greetings Rainer

Hi Rainer! I've always considered myself a "frustrated engineer": math and I are mortal enemies, as I just can't do it, although I wish I could. I have a great respect for that kind of thing, and almost, but, not quite get what's happening: I fully understand/appreciate that it's a super-funky-design, and that someone with a good engineering background "thunked" (thought) it up. My brother used to own a 1968 850 Fiat Spider: Italians are famous for being "ultra-creative" engineers. This car didn't have an normal oil filter, ohhh-no, but, the way it filtered the oil was, it would pass the oil through veins in the fan pulley and the centrifugal force would throw the heavier particulate outward to the pulley housing... Every so often you'd have to scrape it out with a hammer and screw driver-- WOW--SERIOUSLY? So, that said, I know how things work, but, I can't give you all the math behind it: that's why people like you get paid, and I paint pictures Jaybird

I've had experience with centrifugal oil filters in the Navy and with the early Hondas I've rebuilt.
There may be other examples (probably many), but these are the ones I remember. The Honda filter was a simple chain-driven unit that the engine oil passed through, got spun to send impurities to the outer circumference, and the clean oil was pumped out of the center. You had to clean it out pretty frequently.
