Re: Upgraditis hit: VBM Super Leva
I think Brett has it.
My understanding is that the half-stop allows the basic pressure of the system to begin the pre-infusion. If it is not plumbed in, there is no basic pressure, so that position opens a valve but nothing happens on a tank machine.
The built-in pre-infusion run by the pump is the essence of the E-61 design according to the patent.
