Has anybody got a drawing for a Vacuum Limiting/relief valve please? I think that one appeared in Model Engineer recently but I am unable to access archive even though I have a digital subscription until my renewal. I have found a drawing in ME from 1981 but believe there was a more recent drawing. Many thankc John

Wouldn't it take the form of a boiler safety valve installed in reverse?

I am asking for a non computer friend so not sure myself. The one that I have seen looks like a "mushroom" with an adjuster on the bottom, it has a rubber/plastic diaphragm inside. The top main piece was about 20mm across. The nearest thing that I can think of similar appearance is "Petrol Miser" from the 1960s.
