Abstract (en)
[origin: WO2011045104A1] The invention relates to a circuit (40) for operating a solenoid valve, comprising at least one component that is designed to generate a decreasing temporal course of the difference between a force oriented in the opening direction of the solenoid valve and a force oriented in the closing direction of the solenoid valve during a closing process of the solenoid valve, at least following the point in time when the solenoid valve closes. The invention further relates to a method for operating a circuit for a solenoid valve.
