Abstract

Es wird eine Einrichtung zum Verdichten von körnigen Formstoffen, insbesondere Giessereiformstoffen vorge­ schlagen, bei welcher in Wirkungsrichtung des Druckstosses mehrere rohrförmige Hohlkörper zwischen dem Druckbehäl­ ter und dem Formkasten angeordnet sind zwecks Durchlei­ tung des gasförmigen Mediums auf die Formstoffoberseite. Durch die Aufteilung des Durchgangsquerschnittes in meh­ rere selbständige Querschnitte wird der Hub zum Oeffnen des Ventils erheblich reduziert und damit ein rasches Oeffnen des Dichtorganes erreicht. It becomes a device for compacting granular Molded materials, especially foundry molded materials beat in which direction of action of the pressure surge several tubular hollow bodies between the pressure vessel ter and the molding box are arranged for the purposes of Durchlei processing of the gaseous medium on the top of the molding material. By dividing the passage cross-section into several If the cross-sections are independent, the stroke will open of the valve significantly reduced and thus a quick one Opening of the sealing element reached.
