The invention proposes a fuel delivery device for a fuel injection device of an internal combustion engine, having a delivery pump () and having at least one high-pressure pump (). By means of the delivery pump (), fuel from a storage container () is delivered to the suction side of the high-pressure pump (), and fuel is delivered into a high-pressure region () by the high-pressure pump (). The delivery pump () has an adjustable displacement volume, which means that a variable quantity of fuel can be conveyed at the same rotational speed.

Fuel delivery device

A method and device are described for driving an electromagnetic consumer, which includes a movable element. This element includes a solenoid-operated valve for controlling the metering of fuel into an internal combustion engine. A switching instant is determined within a timing window. Within the timing window, the voltage being applied to the consumer is able to be controlled to an adaptable setpoint value in open and/or closed loop.
