Abstract

Es wird ein Dichtelement (1) für einen Kolben (2) eines Antriebs einer Tür oder dergl., beschrieben, wobei der Kolben (2) in einem mit einer Hydraulikflüssigkeit gefüllten Aufnahmeraum verschiebbar angeordnet ist, und wobei das Dichtelement (1) den Kolben (2) gegenüber die Innenwandung (12) des Aufnahmeraums führt und abdichtet. Das Dichtelement (1) weist eine Aussparung (8) zum Einbringen eines Dichtrings (10) auf, welcher das Dichtelement (1) gegen den Kolben (2) abdichtet.A sealing element (1) for a piston (2) of a drive of a door or the like is described, wherein the piston (2) is displaceably arranged in a receiving space filled with a hydraulic fluid, and wherein the sealing element (1) supports the piston (1). 2) relative to the inner wall (12) of the receiving space leads and seals. The sealing element (1) has a recess (8) for introducing a sealing ring (10), which seals the sealing element (1) against the piston (2).
