Abstract
A magnetic valve that is switchable in two directions is proposed. The valve comprises an armature, which is firmly joined to a valve body; at least two magnetic coils disposed in one plane and having ferromagnetic cores inserted in them; and two pole bodies, which are joined to the cores and with them belong to the electromagnetic circuit, and acts on the oppositely located flat sides of the armature. Permanent magnets are inserted into the pole bodies in such a way that the operative surface area of the pole bodies is divided into a number of zones, each having a homogeneous magnetic orientation in which the number of zones is equal to the number of magnetic coils.
