An impulse solenoid valve with at least one solenoid coil, a magnetically soft magnetic circuit which comprises a stationary yoke and a movable solenoid core, and with a permanent magnet which is accommodated in the magnetic circuit such that it sectionally interrupts the magnetic circuit, is characterized in that a first portion and a second portion of the magnetic circuit each directly contact the same on opposite sides of the permanent magnet, preferably over the full surface.

Impulse solenoid valve

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.

Arrangement of stringed solenoid drives

A solenoid unit for a solenoid valve, including a magnet coil and a ferromagnetic circuit which surrounds the magnet coil and comprises a stationary magnet housing, a movable magnet armature and, if required, an armature antipole, the magnet housing being assembled of a cover, a shell and a bottom in the form of multiplayer transformer sheet metal parts.
