Device and method for regulating a pressure in accumulator injection systems having an electromagnetically actuated pressure adjusting element |
摘要 |
A device for regulating a pressure in a high pressure accumulator of a fuel injection system includes a pressure adjusting element which has a shut-off element and an electromagnetic drive actuating the shut-off element. A first regulating device is connected to the pressure adjusting element and compares a pressure value obtained in the high pressure accumulator with a given setpoint pressure value. A drive signal with a setpoint current value for the electromagnetic drive is determined as a function of the comparison. A second regulating device is connected downstream of the first regulating device for comparing a current value of a current flowing through the 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. A method for regulating a pressure in a high pressure accumulator is also provided.
