CIRCUIT ARRANGEMENT AND METHOD FOR ACTUATING A RECHARGEABLE AND DISCHARGEABLE ELECTROMECHANICAL ACTUATOR

摘要

The invention relates to a circuit arrangement and a method for actuating a rechargeable and dischargeable electromechanical actuator (10, 11), especially a fuel injection valve of an internal combustion engine. The charged actuator (10, 11) is discharged by means of a first discharge branch (31) which is connected to the actuator (10, 11). The actuator (10, 11) is also discharged with the aid of a second discharge branch (32) that is connected to the actuator (10, 11), the second discharge branch (32) being triggered following the first discharge branch (31) by means of a controller (30) so as to discharge the actuator (10, 11) while the first discharge branch (31) is in the process of discharging the actuator (10, 11). The invention advantageously makes it possible to prevent residual charges from remaining in the actuator (10, 11) during discharging and discontinuities from occurring when actuating the actuator (10, 11), said residual charges and discontinuities disrupting the desired functionality of the actuator (10, 11).
