Abstract
A rodless pressure cylinder (1) has a cylinder housing (2) with a longitudinal slot (6) through it and is closed on each end by a cylinder cap (12). The longitudinal slot (6) is sealed on its inside by an inner sealing strip (7) and as necessary is also covered on its outside by an outer sealing strip (8). The provided sealing strips (7,8) are fastened by special clamping elements (11), in or on the longitudinal slot (6). The cylinder caps (12) are provided on each side with connectors for the feed and discharge of pressure medium. Since the sealing strips (7,8) are fastened by the special clamping elements (11) independent of the caps (12), the cylinder caps (12) can be installed in various positions on the cylinder housing (2). They are constructed rotationally symmetrical for this purpose, which is particularly valid for the pressure medium channels in the interior of the cylinder caps (12). The cylinder caps (12) can therefore be mounted on the pressure cylinder (1), respectively such that the respective connector (17) for the pressure medium lies in a sufficiently accessible position of the mounted pressure cylinder (1).
