HYDRAULIC CYLINDER

The invention relates to a hydraulic cylinder comprising a cylinder (2), a piston element (3) movably guided in the cylinder (2) in a working direction (W) and comprising an active surface (5, 7), anda first opening for feeding a fluid into a cylinder chamber (4, 6) by means of the active surface (5, 7). A working pressure of the fluid acting on the active surface (5, 7) drives the piston element(3) in the working direction (5, 7). The active surface comprises a first partial surface (5) and at least one second partial surface (7), the cylinder chamber being divided into a first sub chamber(4) with the first opening (4a) by means of the first active surface (5) and a second partial surface (6) with a second opening (6a) by means of the second partial surface (7), and the partial surfaces (4, 6) are hydraulically separated from each other at least in a selectable operating mode. 本发明涉及种液压缸，其包括：缸体(2)；在缸体(2)中沿作用方向W可运动地被引导的活塞元件(3)，该活塞元件具有作用面(5、7)；以及第开口，以用于将流体输送到在作用面(5、7)之上的缸体腔室(4、6)中，其中，流体的作用到作用面(5、7)上的工作压力沿作用方向驱动
