Abstract

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.
