A piston (1, 2) is surrounded by concentric inner and outer cylinders (3, 4). The inner cylinder (3) has a double mantle, allowing a hydraulic fluid to flow in the region (28, 29) formed between the inner and outer mantles (9, 10) via inlet and outlet channels (20-23). A pressure chamber between the piston and inner cylinder has its outer wall defined by the inner cylinder. A pressure chamber between the inner and outer cylinders has its inner wall defined by the outer mantle (9) of the inner cylinder. |
