摘要：
A fuel-supply system for an internal combustion engine, particularly of a motor vehicle. The fuel-supply system is provided with a pump for delivering fuel into a storage chamber and for producing a pressure in the storage chamber. In addition, provision is made for a pressure sensor for measuring an actual value of the pressure in the storage chamber, as well as a pressure-control valve for influencing the pressure in the storage chamber. A control unit is provided with means by which the pressure in the storage chamber is controllable to a setpoint value. In addition, the control unit is provided with means by which the closed-loop control of the pressure in the storage chamber is able to be superseded by an open-loop control.
