Anybody ever use the "Dilating O-ring Checkvalve" principle in an MSP valve?

If suitably simplified, I think it might have real advantages over the traditional plunger-and-spring arrangement.

...applied from right to left in the drawing blows the ring out of the vented groove and up the taper, allowing flow. Pressure in the opposite direction allows the ring to slide down the taper into the groove, sealing and stopping flow.

Voila'! A checkvalve with only one moving part and no spring to rust.

(That's French for "Lookitdat!")

like the check valves for fishtanks... the front of the valve would need to be able to unscrew to get the diaphram in (or out, for replacement)

how would that plug a hole?


edit: oh wait i was looking at it wrong. so the red dots are the cross section of the o-ring. so whats with the little cap on it? might as well just replace the oring with a rubber disk so you only need one part instead of two....

Missed that on the first read thru

So the pump/piston opens the oring, allows the air into the valve, then the ring reseats and closes the valve till the next stroke

 

Does this save space ie more room for air, or reduces the size of the valve allowing more pump stroke......

edit: spelling
