  1. Patentanspruch:
    Blasventilanordnung für Druckluftschalter, dadurch gekennzeichnet, daß sie aus zwei in einem Zylinder beweglichen Kolben (5, 9) von ungleichem Durchmesser besteht, die so angeordnet sind, daß der eine unter der Einwirkung von dem Zylinder zugeführter Betätigungsluft die Ventilscheibe (2) des Blasventils in Offenstellung führt, während der andere, dem die 'Betätigungsluft über eine Drosselanordnung zugeführt wird, eine entgegengesetzte, begrenzte Bewegung ausführt und hierbei den erstgenannten Kolben in eine solche Stellung zurückführt, daß ein teilweises .Schließen des Blasventils eintritt.
