摘要:
In a method and a circuit system for operating a solenoid valve, particularly for actuating an electrohydraulic gas-exchange valve control, an injection valve, or an intake or exhaust valve of an internal combustion engine, to permit the simplest possible driving of the solenoid valve, the solenoid valve is acted upon in a controlled manner in a cycle including three phases, in which in a pull-up phase, the solenoid valve is connected for a predefined time duration to a first voltage of predetermined magnitude for generating a pull-up current, in a holding phase is connected to a second voltage of predetermined magnitude for generating a holding current, and in a de-energize phase is separated from both voltages.
