there should be two valves/passages.
One to hold the 'pressed in' oil and a passage or valve to
allow
the oil to pass to the pump front.
Sounds like you might have something blocking the oil
from the reservoir entering the pump.
Is the ball valve you described in the plunger or the body
of the
pump? There should be a spring to set the ball on it's seat.
Withdrawing the plunger...allows oil in from the reservoir.
Pushing in should push that oil in behind the ram WHILE
the reservoir gets sealed off to stop the oil from simply
returning to the reservoir .
