Claims (1)

Patent-Anspruch:Patent claim: Ein Absperr-Drehschieber für Rohrleitungen, bestehend aus einem Gehäuse CIa1/ in Form eines Kreisausschnittes, dessen Theil f behufs Reinigung des Innenraumes auch bei geschlossenem Schieber abnehmbar ist, und einem in dem Gehäuse um einen aufserhalb der Rohrachse liegenden Zapfen c schwingenden Schieberkolben, dessen als rechts- und linksgängige Schraubenflächen zur Achse c gestaltete Dichtungsflächen sich keilartig zwischen die entsprechend gestalteten Dichtungsflächen der Rohrenden pressen.A rotary shut-off valve for pipelines, consisting of a housing CIa 1 / in the form of a circular section, the part f of which can be removed for cleaning the interior even when the valve is closed, and a slide piston swinging in the housing around a pin c lying outside the pipe axis, whose Sealing surfaces designed as right-hand and left-hand screw surfaces to the axis c are pressed in a wedge-like manner between the correspondingly shaped sealing surfaces of the pipe ends.
