Patent number: 6347783Abstract: The object of the invention is to propose an arrangement, with which, when shutting-off or throttling the transport of a liquid with a fitting, the occurrence of undesirable pressures in the pipeline is prevented reliably without supplying air or other gases into the pipeline, as well as without using an air chamber or an auxiliary fitting or additional controllers and without specifying a fixed shutting off and throttling rate. The implementation of the invention shall prevent impermissible pressures upstream as well as downstream of the shutting-off fitting. The invention provides that a braking system is connected with the pipeline and is driven by liquid pressure in the pipeline, acting on the drive shaft, the drive spindle or the drive rods of the shutting-off or throttling fitting.Type: GrantFiled: June 26, 2000Date of Patent: February 19, 2002Assignees: Forschungszentrum Rossendorf E.V., Fraunhofer-Gesellschaft zur Foerderung der angewandten Forschung E.V.Inventors: Horst-Michael Prasser, Stefan Schlueter, Andreas Dudlik
