US 11,885,453 B2 · Damping device

Abstract

A damping device, in particular for damping or preventing pressure surges, such as pulsations, in hydraulic supply circuits, preferably in the form of a silencer, has a damping housing (2) encompassing a damping chamber (10). The damping housing (2) has at least one fluid inlet (6) and at least one fluid outlet (8), as well as a fluid receiving chamber extending between the fluid inlet (6) and the fluid outlet (8). During operation of the device, a fluid flow coming from the fluid inlet (6) passes through the damping chamber (10) towards the fluid outlet (8). A wall part of the fluid receiving chamber extends as a guide element (16) in at least one direction of extension transverse to the direction of the fluid flow. In the damping chamber (10), several guide elements (16) are provided, against which guide elements the fluid can flow to alter the flow velocity in certain areas.

Dependent claims

A damping device for damping or preventing pressure surges in hydraulic supply circuits, comprising:

a damping housing encompassing a damping chamber and having first and second opposing end walls, a fluid inlet and a fluid outlet, the damping chamber extending between the fluid inlet and the fluid outlet the damping housing configured such that a fluid flow in a flow direction coming from the fluid inlet passes through the damping chamber towards the fluid outlet, both the damping housing and the damping chamber being of a circular cylindrical or polygonal form;
and
plural identical hollow guide elements extending between the first and second opposing end walls of the damping housing in the damping chamber in a direction of extension transverse to the flow direction of the fluid flow against which the fluid can flow and which alter the flow velocity in certain areas, the guide elements being integral with the first and second opposing end walls, having interior cavities being open at opposite ends thereof through the first and second opposing end walls and having conical axial end portions adjacent to one another and the first and second opposing end walls.
