Abstract
A method and a device are proposed for driving a solenoid valve that has stroke ranges of a stable equilibrium of forces and stroke ranges of an unstable equilibrium of forces. For setting the predetermined differential pressure across the solenoid valve, a driving signal quantity is generated which is selected such that the stroke ranges of an unstable equilibrium of forces are avoided or the dwell time of the solenoid valve in these ranges is reduced.
