well an image search for "Ball valve in toilet cistern" will get you a

on my results page this is on the 5th line of images.

I found that thank you. I really need something a bit higher resolution nd
with more detail.

My valve is like that but 180 degrees out. The diaphragm is at the inlet

dropped the whole thing in the cistern once upon a time and put it
together back to front.
