    Boondock when I went for a hydraulic course I learnt that the area that is trying to be displased is important.The bigger the area the more it is affected by the pressure.I hope this is accurate and helpful ,I may verry well be wrong.

    the striker is quite heavy and gathers quite a bit of momentum by the time it hits the valve.

    Inertia, mass of the hammer is important. One of the parts used to "tune" a rifle.
