Abstract (en)
A piston seal (6) for a piston of a rodless slotted cylinder, having an oblong cross section, wherein an inner sealing band (3) is provided on the inside of the slot, and wherein the seal (6) has an oblong ring-shape corresponding to the cross section of the cylinder (Fig. 1a) with an inner holding portion (7) and a surrounding sealing lip (8). The invention is distinguished by the sealing lip (8) comprising a radially outwardly directed protrusion (9) in the area of the inner sealing band (3), in order to ensure sealing contact of the sealing lip (8) with the inside of the sealing band (3) when the latter is allowed to be deformed when pressurising the cylinder. <IMAGE>
