A piston-rod-less working cylinder, for compressible media, with a braking device between a force collector, wherein the collector is formed as a slider with slider tracks, and a cylinder casing forming counter slider tracks and receiving the working cylinder, with sliding bodies disposed between the slider tracks and the counter slider track, wherein the sliding bodies rest against the slider tracks disposed at profile sides of the casing cross-sectional profile and against the counter slider tracks, with adjusting elements, wherein the adjusting elements are positioned and engaged in a direction toward the sliding bodies for adjusting a slide play or brake play, respectively, and wherein
- (a) a braking device, including said sliding bodies (7) and adjusting elements (12), is disposed, relative to a pair of said slider tracks (5) and of said counter slider tracks (6), with a side distance relative to a slider plane and a casing center longitudinal plane (19), respectively;
- (b) the braking device (2) is additionally furnished in an upper region between the sliding bodies (7) and the adjusting elements (12), respectively, with a force member (20), which force member (20) operates in a region (21) of the casing center longitudinal plane (19),
- (c) a lever element (22), which lever element (22) engages with lever arms (22a, 22b) centrically the adjusting elements (12) and where a press-on force engages the lever element (22) in the center for thereby generating the brake force.
