Abstract:
In combination with a high pressure accumulator for a fuel injection system, a device for regulating a pressure in the high pressure accumulator, comprising:a pressure adjusting element connected to the high pressure accumulator and having a shut-off element and an electromagnetic drive actuating said shut-off element;a first regulating device connected to said pressure adjusting element for performing a comparison between a pressure value obtained in the high pressure accumulator and a given setpoint pressure value, and, as a function of the comparison, determining a drive signal with a setpoint current value for said electromagnetic drive; anda second regulating device connected downstream of said first regulating device for comparing a current value of a current flowing through said electromagnetic drive with the setpoint current value and readjusting the current value in response to a deviation between the current value and the setpoint current value.
