Manual Extract:

The operation of the injector is easy and positive.
A measured quantity of fuel under high pressure moves from the injection pump to the high pressure channel in the injector body. The fuel then moves through the valve stop channel and enters the pressure chamber which is around the valve in the injector tip.

When the pressure of the fuel against the valve is more than the set spring orifice, the valve is moved from the seat. This permits the fuel under high pressure to enter the injector tip. The fuel then moves through the spray orifices and to the combustion chamber. The fuel reaches the combustion chamber in an atomized condition.

When the fuel delivery stops, the pressure against the valve is decreased and the control spring immediately returns the valve to the seat. This removes the danger of leakage, after the measured amount of fuel has been released. The valve opens and closes vary rapidly with a very clear noise.
A small amount of fuel leaks, during injection, through the controlled clearance between the tip assembly and the injector body. This leakage adds lubrication to all the moving parts in the injector. This fuel then moves through the leak off channel, leak off lines and returns to the fuel tank.
