    摘要: In order to increase the pressure of the hydraulic medium in cylinders, especially those of the hydraulic longwall construction used in underground mining and tunnel construction, a control unit 21 is used which has suitably controllable, releasable check valves 29, 30 and 25, as well as a blockable check valve 31. These check valves and the associated directional valves create the possibility of filling both the cylinder space 20 proper and the piston rod cavity 26, which enables the pressure adjustment process with hydraulic medium in a specific manner, or accordingly their discharge, with no risk of reciprocal influence, seizing, or other damage.

    摘要: A method and corresponding cylinder for pressure amplification in cylinders are disclosed. A second pressurizing piston with a small piston rod is arranged within the cylinder, in other words, within the cylinder housing, by means of which the piston surface cavity in the vicinity of the piston or the pressure medium present there can be further compressed. It is thus possible to increase the stroke displacement where required or to increase the pressure within the cylinder. Further advantages can also be achieved with the above.
