Abstract
For both adjustable flow restrictors D1, D2 having variable cross-sections a common adjustment element 21 is provided mechanically coupling the restrictors in a hydraulic damping assembly D for regulating parameters of a regulating system S, in particular of a variable displacement pump P, the restrictors D1, D2 being provided in discharge paths 12, 13 such that the restrictor cross-sections can be varied within an adjustment stroke h. The common adjustment element 21 allows to simultaneously and oppositely vary the flow restriction cross-sections A of both flow restrictors having a variable cross-section. The restrictor cross-sections A of both flow restrictors D1, D2 having a variable cross-section of a hydraulic damping assembly S in a regulating system S of a variable displacement pump P can be varied simultaneously and oppositely according to an imminent specification of the system set by the manufacturer.
