Abstract
An injection device having at least one injection nozzle arrangement for intermittent discharge of a prescribed quantity of fuel. The nozzle arrangement is actuatable in response to an increased fuel pressure in the nozzle arrangement, and has an inlet communicating with the nozzle arrangement for supplying fuel. An outlet communicates with the nozzle arrangement for partial return of the fuel to provide a flow of fuel through the nozzle arrangement and thus uniflow scavenging and cooling of the injection device. The flow of fuel is limited between the inlet and outlet at least temporarily to allow an increase in fuel pressure required to actuate the nozzle arrangement.
