Patentansprüche:Patent claims: 1. Durchfluß-Einstellorgan für Großwasserzähler-Prüfstände mit einer abflußseitig in die Rohrleitung eingebauten Durchflußregel- bzw. -absperrvorrichtung, z. B. einem Klappenventil, dadurch gekennzeichnet, daß der Ventilabsperrkörper über eine Betätigungsstange (1) mit einem an sich bekannten, vorzugsweise hydraulischen Betätigungszylinder (3) verbunden ist, der durch einen zwischen dem Kolben (4) und dem Zylinderkopf (11) eingesetzten Faltenbalg (9, 6) zwei völlig voneinander getrennte, einerseits außerhalb des Faltenbalges und unterhalb des Kolbens und andererseits innerhalb des Faltenbalges oberhalb des Kolbens liegende Druckräume aufweist, deren beide Druckmittelein- und -auslaßanschlüsse (15, 16) im Zylinderkopf vorgesehen sind, wobei der für die Schließbewegung des Ventilabsperrkörpers als Druckmittelauslaß wirkende Kanal (14) mit einer erst kurz vor der Kolbenendstellung progressiv wirksam werdenden Drossel (13) versehen ist.1. Flow setting element for bulk water meter test stands with a flow control or shut-off device built into the pipeline on the outflow side, e.g. B. a flap valve, characterized in that the valve shut-off body via an actuating rod (1) with a per se known, preferably hydraulic actuating cylinder (3) is connected, which by a between the piston (4) and the cylinder head (11) inserted bellows (9, 6) two completely separate, on the one hand outside the bellows and below the piston and on the other hand inside the Bellows above the piston has pressure chambers, the two pressure medium inputs and outlet connections (15, 16) are provided in the cylinder head, the one for the closing movement of the valve shut-off body acting as a pressure medium outlet channel (14) with a first shortly before the piston end position progressively effective throttle (13) is provided. 2. Durchfluß-Einstellorgan nach Anspruch 1, dadurch gekennzeichnet, daß die Drossel (13) aus einem parallel zur Betätigungsstange (1) liegenden und mit ihr fest verbundenen zugespitzten Stift besteht, der während der Endbewegung der Betätigungsstange in den Auslaßkanal (14) eindringt. 2. Flow adjusting member according to claim 1, characterized in that the throttle (13) from a pointed pin lying parallel to the actuating rod (1) and firmly connected to it which penetrates into the outlet channel (14) during the final movement of the actuating rod.
