    • Die Erfindung betrifft ein Verfahren und eine Vorrichtung zur Durchführung des Verfahrens zur Dosierung von mit Überdruck beaufschlagten Fluiden mittels eines bistabilen, elektromagnetisch schaltenden Dosierventils mit integriertem Sensor zur Ermittlung der rheologischen Fluideigenschaften. Durch Abschwächung und Verstärkung entgegengesetzt gepolter Permanentmagnetfelder, die zwei stabile Lagen innerhalb der Dosierkammer definieren, werden durch eine elektronisch angesteuerte stromdurchflossene Spule diskrete Schaltzustände für einen axial in einer Dosierkammer beweglichen magnetisierbaren Schaltkörper erzeugt und bei der Bewegung des Schaltkörpers in eine stabile Lage die Magnetfeldänderung mit einem Sensor erfasst wird. Die Auswertung der vom Schaltkörper hervorgerufenen Magnetfeldänderung unter Beachtung der Schaltzeiten ermöglicht Rückschlüsse auf die aktuelle Viskosität des Fluides und damit die Möglichkeit einer genauen Dosierung von Fluidmengen.

    • The invention relates to a method for causing a first body (10; 20) having magnetostrictive properties, and a second body (11), against which said first body is in bearing contact with a certain grip between the contact surfaces, to move with respect to each other while substantially maintaining said grip, wherein a magnetic field profile having a field strength variating in the longitudinal direction of the body is generated in a longitudinal section in said first body and is caused to be moved along the same line as said first body is moved along with respect to said second body. According to the invention electric current is supplied separately to individual coils in a set of coils (12). Furthermore, the supply of current is controlled to cause said coils (12) to generate partial magnetic fields, forming together said magnetic field profile. The invention is related also to a device for carrying out the method. Said device comprises a plurality of sets of coils (12, 12A-12D, 12F-12I), which are arranged along said second body (11), and power supply means are provided for a controllable supply of electric current to said coils (12, 12A-12D, 12F-12I). Furthermore, control means (23-27) are provided for controlling current separately to each of said coils (12, 12A-12D, 12F-12I).

    • Method and device for making a first body (8), having magnetostrictive properties, and a second body (6), against which said first body is in bearing contact with a certain grip between the contact surfaces, to move with respect to each other while substantially maintaining said grip. According to the invention a magnetic field is made to sequentially influence only one of adjacent partial sections of said magnetostrictive body (8), starting from the front end of the body as seen in the intended direction of movement. The magnetic field is adjusted so that the respective partial section under the influence of the magnetic field undergoes an increase in length, at the same time being subject to a contraction in the transverse direction which is big enough in order to decrease, preferably eliminate the grip between the bodies. The device includes a rod (8) of magnetostrictive material, which is clamped within a tubular body (6), one end of which being attached to a rigid supporting structure. The magnetostrictive rod (8) is connected to a bar, a link etc. having its opposite end connected to the element to be actuated by the movement of the rod in the tubular body (6).
