HYDRAULIKZYLINDER ASSEMBLY FOR A MACHINE FOR PRODUCING A FIBROUS WEB, IN PARTICULAR A paper or board machine

摘要

a hydraulic cylinder assembly (1) for a machine for producing a fibrous web, in particular a paper or board machine, comprising a hydraulic cylinder (2) including a cylinder housing (21) and one in the cylinder housing (21) movable piston (27) is presented comprising the the cylinder housing (21) in a cylinder head-side chamber (22) and a cylinder-bottom-side chamber (23) is divided, and at least one digital hydraulic pressure controller (3) that is in the assembly (1) is integrated, the zylinderkopfseiiigen chamber (22) and the cylinder-bottom-side chamber (23) is associated, and controls an inflow and outflow of working fluid to and from the chambers (22, 23) to the pressure of the working fluid in at least one of the two chambers (22, 23) to set the hydraulic cylinder (2), wherein the valves (31) of the digital hydraulic pressure controller (3) are mounted in the piston (27) of the hydraulic cylinder (2).
