Pressure regulator

thingiverse

My first attempt for a throttle for my air engines. I haven't printed it yet.... uses m3 screws, som old inner tire als diaphragm and a fairly strong spring that seems to take 2.5kg per mm compression. Intake and exhaust are at the bottom for now. It will fit nicely between de cylidners of my v-twin engine ;) Be careful... update 2019-06-02 It sort of works but takes a lot of effort and needs a fine adjustment. seen the design and me putting a constant pressure on the lever, it won't work if operated manually. attaching a servo should work.
