Abstract: To accomplish this object, a device is designed and is characterized in that in the interior of the housing there is provided at least two baffle plates which are offset in the direction of the housing axis and between them form at least one third chamber and in that for the flow connection between the chambers a passage is provided in at least one baffle plate. Additionally, the device according to the present invention is characterized in that a switching means in the electric supply circuit for the magnetic coil has at least a third operating condition, in which the flow of current is interrupted by the at least one magnetic coil, and in that the switching means assumes this third operating condition in each instance between a first and a second or between a second and a first operating condition.

Abstract: The invention relates to a device for eliminating scale and for preventing the formation of scale in pipe systems through which a liquid, for example water, flows, in which arrangement the liquid is exposed to a magnetic field generated by a magnet coil, comprising an internal space which is formed in a housing and which is circularly symmetrical to a housing axis, with a partition which subdivides the internal space into two chambers and which is arranged perpendicularly to the housing axis, which partition is arranged with a distance on all sides from the inside surface, limiting the internal space, of the housing, with an inlet opening at one chamber, formed in the housing, and with an outlet opening at the other chamber, formed in the housing, in which arrangement the inlet opening and the outlet opening are in each case opposite to the central area of the partition, with a magnet coil, which concentrically encloses the partition and which is arranged in an annular recess of the housing, for generating th
