Abstract (en)
The piston has a two-piece supporting shell, whose both halves are arranged symmetrically with respect to a middle radial plane and in which a permanent magnetic ring is axially enclosed. A cylindrical piston bearing surface (22) stretches axially between sealing lips (20). Two parallel, uniform metal discs and the magnetic ring are formed in disk shape as supporting shell halves, and form a flat sandwich arrangement.
Abstract (de)
Um einen Magnetkolben mit einem zweiteiligen Stützkörper(12,12), dessen beide Hälften(je Metallscheibe 12) einen permanentmagnetischen Ring(14) axial einschließen, relativ schnell und einfach herstellen zu können, wird vorgeschlagen, als Stützkörper-Hälften zwei parallele, gleiche Metallscheiben(12,12) und einen Magnet-Ring(14) in Scheibenform vorzusehen, die zu dritt eine flache Sandwichanordnung(12/14/12) bilden (Fig.2).
