Abstract (en)

A sealing strip (3) seals the longitudinal slot (1) on both sides of the piston from the inside and in the area of the transmission component is fed through the piston. With two longitudinally extending sealing areas (4,5) is a sealing strip (6) in the area of the cylinder inside end of the longitudinal slot. On the outside of the sealing strip is at least one holding strip (7) with two holding components (9) opposite to one another and directed outwards. The holding components of the holding strip in order to hold the sealing strip in the longitudinal slot (1) engage positively on holding edges (10) provided on the cylinder.

Abstract (de)

Bei einem kolbenstangenlosen Druckmittelzylinder ist der Längsschlitz (1) beidseits des Kolbens von innen her mit einem Dichtband (3) abgedichtet, welches Halteelemente (9) aufweist, die zum Halten des Dichtbandes (3) bei drucklosem Innenraum an am Zylinder vorgesehenen Haltekanten (10) formschlüssig eingreifen. Es wird damit ein sicheres Abdichten des Innenraumes auch im drucklosen Zustand erreicht bzw. eine Anfangsleckage bei Druckbeaufschlagung des vorher drucklosen Innenraumes verhindert. <IMAGE>
