Abstract

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.

Figure 00000001
In the case of a rodless pressure medium cylinder, the longitudinal slot (1) on both sides of the piston is sealed from the inside with a sealing tape (3) which has holding elements (9) which hold the sealing tape (3) on the holding edges (10) provided on the cylinder when the interior is depressurized. intervene positively. In this way, a secure sealing of the interior is achieved even in the unpressurized state, or an initial leakage when pressure is applied to the previously unpressurized interior.
