Abstract

The assembly comprises two globe sliding valves. They are mounted in series on the upper-flow pressure duct of a hydraulic machine, esp. pump turbine. There is an intervening coupling element, and swivelling spherical closing pieces built into housing units, acted on by working cylinders for opening and closure; together with metal rings. The working cylinders are attached to the coupling element between the slides in the assembly, for activation of their closing pieces. The cylinders' axes are pref. aligned parallel to the axis of water outflow. The number of connecting flanges can be reduced, and the assembly is compact.
