Abstract
The invention relates to an arrangement of stringed solenoid drives (), particularly for solenoid valves, wherein each solenoid drive comprises a magnetic circuit with a yoke (), moveable armature (), and an excitation coil () arranged on the yoke. The magnetic circuits of neighboring solenoid drives have pre-magnetization with the same polarity and at least approximately the same strength. Due to the pre-magnetization, the magnetic potential difference between neighboring magnetic circuits is reduced. The pre-magnetization is thus carried out with the same polarity as the excitation by current flow in the excitation coil.
