Abstract
The aim of the invention is to protect hydraulic assemblies, in particular those used for hydraulic longwall working in coal mining. To achieve this, pressure regulating valves () are used, the damping chambers of which () are located, configured and connected to the inlet side () in such a way that a system pressure constantly prevails in said chamber () and only drains in a restricted manner when the pressure in the regulating valve () is released, thus preventing the occurrence of detrimental vibrations.
