Abstract

A damping device 10 for damping the flow of a fluid 14 in a hydraulic assembly 12 is provided. The damping device 10 has a gas-filled damper chamber 32 and a damper membrane 30. The damper membrane 30 separates the flowing fluid 14 off from the damper chamber 32 and the damper chamber 32 is formed with a porous material 36.
