Need help on my 34 brake vacuum valve

Can not find a breakdown on my vacuum valve. I assumed it had a rubber diaphragm but when I took if apart it looks like a piston or disc operated.
I would think the piston would come out but it is frozen, got it soaking overnight and will try tomorrow to got it out. I also don't quite understand the gasket or seal also. Would love to see a breakdown if anyone has one.
Dave hope you can help, I am sure you took yours apart on your 34......
