Abstract
An injection system for an internal combustion engine including at least one injector and a high-pressure accumulator, which has a fluid connection to the at least one injector on the one side and has a fluid connection to a fuel reservoir via a high-pressure pump on the other side, wherein a suction throttle is associated with the high-pressure pump as a first pressure-setting element. At least two pressure control valves are provided, via which the high-pressure accumulator can be brought into fluid connection with the fuel reservoir.

1-10. (canceled)
An injection system for an internal combustion engine, comprising:
- at least one injector;
- a high-pressure accumulator which is fluidically connected at one side to the at least one injector and at another side via a high-pressure pump to a fuel reservoir;
- a suction throttle assigned to the high-pressure pump as a pressure setting element;
- and
- at least two pressure regulating valves by which the high-pressure accumulator is fluidically connectable to the fuel reservoir.
