  • Patent number: 7975674
    Abstract: A fuel pump and a method for controlling a fuel pump. At least two pumps run at a mutual phase displacement such that they are able to receive fuel during different periods of time. A control unit causes a valve, which is only settable in an open position and a closed position, to lead a desired amount of fuel to the respective pump. The control unit places the valve in the open position for a variable portion of the periods so that an individually controlled amount of fuel is led to the respective pump during those periods. Maintenance of good efficiency of the fuel pump and low noise emissions is thus made possible in operating situations where the fuel pump delivers a reduced amount of fuel.
