Abstract: A potlike hydraulic cylinder consists of a cylinder pot (1), a piston (2), which constitutes a cover for the pot, a rubber-elastic plastic body (4), which occupies the pressure space between the cylinder pot (1) and the piston (2) and which forms a closed pocket (6) that is provided with a partition (7), which is substantially parallel to the bottom and constitutes the bottom of the pocket and is connected to at least one bottom extension (8) of the cylinder pot (1), which extension protrudes axially into the plastic body (4), and at least one pressure line (9) for a hydraulic fluid, which pressure line extends through the bottom extension (8) and the partition (7) and opens into the pocket (6). To ensure desirable operating conditions, the partition (7) is adjoined by a peripheral wall (10), which protrudes toward the piston (2).
