Abstract

Vorrichtung zur Erzeugung eines Unterdrucks im abgedichteten Raum einer Tablettenpresse oder eines Isolators, mit einem an den abgedichteten Raum (12) angeschlossenen Gebläse (16) und einer Luftöffnung (18) zum abgedichteten Raum, wobei mit dem abgedichteten Raum (12) die Ansaugseite eines Ejektors (26) verbunden ist, dessen Treibmittelanschluß über ein Ventil (38a) mit einer Druckluftquelle verbindbar ist, mit einem Sensor (42), der mit einer Unterdruckregeleinheit (44) verbunden ist, die das Ventil (38a) öffnet, wenn der Sensor (42) einen Druck im abgedichteten Raum (12) mißt, der oberhalb eines vorgegebenen Unterdruckwertes liegt, wobei ein zweites Ventil (20) der Zuluftöffnung (18) zugeordnet ist, das je nach Ausführung geöffnet bleibt oder von der Unterdruckregeleinheit (44) angesteuert und geschlossen wird.

Figure imgaf001
Device for generating a negative pressure in the sealed space of a tablet press or an insulator, with a fan (16) connected to the sealed space (12) and an air opening (18) to the sealed space, with the sealed space (12) the suction side of an ejector (26), whose propellant port is connectable via a valve (38a) to a compressed air source, to a sensor (42) connected to a vacuum control unit (44) which opens the valve (38a) when the sensor (42 ) measures a pressure in the sealed space (12) which is above a predetermined negative pressure value, wherein a second valve (20) is associated with the supply air opening (18), which remains open depending on the design or is controlled and closed by the vacuum control unit (44) ,
