The valves on top of the plunger and barrel close when injection is ended. The spring is pulling the plunjer down and creating a vacuum. When the feed hole opens up the fuel flows in. (Fuel also has a slight pressure with it) when the plunjer goes up, the feed hole is blocked off and pressure starts to rise and injection starts. Injection ends when the pressure is released by the helix trough the feed hole. So depending on the position of the helix (controlled by the rack) the fuel is cut off at a certain point after injection, and therefore the fuel delivery is controlled.
