Abstract

An apparatus and a method for driving a solenoid valve, which includes a coil and a movable armature. To move the armature, current and/or voltage is applied to the coil in a clocked manner. By varying the driving, the solenoid valve can be operated optionally as a control valve or as a relief valve.
