Response to The whole thread is about pumper inlet check valves with SPRINGs inside

Wont change anything but cause more pressure to be built which spells work.

"I think you are saying the pressure in the valve exerts force on the check while the pump is filling the valve? Is that what you are thinking"

Sure. I tried to explain my motive with illustration and words. Although I am not to good at either.

It's all physically on the up and up. Where the poppet can be forced back ala slight overpressure required. Because to move the poppet requires work.
But the over pressure required needn't be nearly as much as would be required to blow the poppet *1/16" off the seat. Only enough to move the poppet enough to weaken the seal to where it will yeild to the pressure at hand.

* Reference post above
