Abstract
A fuel injection system includes a pumping plunger which is actuated by an actuating means to displace fuel through a valve controlled outlet. In order to reduce the fuel pressure quickly at the end of the stroke of the plunger valve means is provided which opens due to continued movement of the pumping plunger after the stroke of the actuating means has been halted by a stop.
