That video doesn't do a good enough job of showing fluid flow, but it appears
to have both a piston and screw/gear pump.
Redundant and wonder why?
back on the CP4...there is still the slam when the flow is stopped by the injector
closure
The piezo only opens it against all of those springs, that then slam it shut
after the piezo's turn off. Key is how fast it slams shut to then understand if
there are pressure waves in there going back to the pump & one way valve
That is the function of a 'properly' designed accumulator to absorb and
nullify or reduce down to 'background noise'...
