Abstract:
1. Hydraulic damping assembly for regulating parameters of a regulating system, in particular for a variable displacement pump regulating system, comprising two flow restrictors in separated discharge paths leading to a low pressure side, the acting cross-section of at least one of the flow restrictors being variable within an adjustment stroke characterised in that both flow restrictors have variable cross-sections, the two discharge paths, the low pressure side and an adjustment element commonly provided for both flow restrictors having variable cross-sections and being adjustable through the adjustment stroke are contained in a housing, that the two discharge paths are interconnected in the housing at a discharge path node, that a single discharge path extends from the discharge path node to the low pressure side, that both flow restrictors having a variable cross-section communicate with each other at the discharge path node, one discharge path being a through bore in the housing and the other discharge path leading with a bore to the discharge path node, which bore crosses the through bore laterally, that the adjustment element which mechanically couples both flow restrictors having variable cross-sections is adjustably arranged in the bore or in a prolongation of the bore such that it is adjustable in the direction of the axis of the bore, and that the adjustment element oppositely and simultaneously varies the cross-sections of both flow restrictors having variable cross-sections at least within a portion of the entire adjustment stroke.
