non-return check valve. The fuel in the check valve
cage, spring cage, tip passages and tip fuel cavity is
compressed until the pressure force acting upward on
the needle valve is sufficient to open the valve against
the downward force of the valve spring. As soon as the
needle valve lifts off of its seat, the fuel is forced through
the small orifices in the spray tip and atomized into the
combustion chamber.
