Abstract

The braking device (2) is formed between a force collector (3) and a cylinder casing (1) by way of slider tracks (5) and counter slider tracks (6) and by sliding bodies (7) guiding the slider tracks and counter slider tracks in a working cylinder without piston rod. The adjusting elements (12) for the setting of a sliding or a braking play can be set according to the sliding bodies (7). In order to achieve a compact construction, a low construction height, as well as a lowest possible number of parts, the braking device (2) is disposed symmetrically to a slider plane and a casing center longitudinal plane (19), respectively. The braking device is furnished with a force member (20) acting in the region (21). The lever element (22) engages centrally in each case with the lever arms (22a, 22b) on the adjusting element (12). A press-on force generating the braking force centrally engages the lever elements (22).
