Claims (9)

  1. Eine hydraulisch angetriebene Membranpumpen-Vorrichtung, insbesondere zum Pumpen schwer-zu-pumpender Materialien, wobei die Pumpe mindestens einen Pumpenzylinder (5) enthält, der ein erstes Ende hat mit einem ersten Ein- und Auslass (11) für die zu pumpende Flüssigkeit und ein zweites Ende mit einem zweiten Ein- und Auslass (1) für Hydraulikflüssigkeit, wobei die Ein- und Auslässe mit entsprechenden Ventilen verbunden sind, einem Separator (6), der sich innerhalb des Pumpenzylinders befindet und entlang dieses hin- und her- beweglich ist, wobei der bewegliche Separator (6) eine erste Seite hat, die dem ersten Zylinderende zugewandt ist und eine zweite Seite, die dem zweiten Zylinderende zugewandt ist, wobei:
    - der bewegliche Separator (6) mit der Innenseite des ersten Endes des Zylinders verbunden ist durch eine erste elastische Membran (4) in Form eines Zieharmonika-artigen Balges der im Zylinder (5) ausdehn- und zusammenziehbar ist in Längsrichtung des Zylinders wenn sich der bewegliche Separator (6) im Zylinder hin- und herbewegt, wobei die erste Seite des beweglichen Separators eine erste Kammer (c) innerhalb der ausdehn- und zusammenziehbaren elastischen Membran (4) abtrennt um ein variables Volumen der gepumpten Flüssigkeit in Kommunikation mit dem ersten Ein- und Auslass zu enthalten;
    - der bewegliche Separator (6) mit der Innenseite des zweiten Endes des Zylinders (5) verbunden ist durch eine zweite elastische Membran (10) in Form eines Zieharmonika-artigen Balges der ausdehn- und zusammenziehbar ist in Längsrichtung des Zylinders (5) im Zusammenspiel mit dem Ausdehnen und Zusammenziehen der ersten elastischen Membran (4), wobei die zweite Seite des beweglichen Separators eine zweite Kammer (b) innerhalb der zweiten ausdehn- und zusammenziehbare elastischen Membran (10) abtrennt um ein variables Volumen der gepumpten Flüssigkeit in Kommunikation mit dem zweiten Ein- und Auslass zu enthalten; und
    - ein ringförmiger Raum (a) gebildet wird zwischen den Außenseiten der ersten und zweiten Membranen (4,10) und der Innenwand des Pumpenzylinders (5), und selbiger ringförmiger Raum (a) im Betriebszustand eine Flüssigkeit enthält die die gleiche Flüssigkeit wie die erwähnte Hydraulikflüssigkeit ist oder ähnliche Eigenschaften wie diese aufweist,
    dadurch gekennzeichnet dass:
    der bewegliche Separator (6) in Form eines Kolbens vorliegt der verschiebbar im mittleren Bereich der Innenseite des Zylinders (5) angebracht ist zwischen der ersten und zweiten Balg-artigen Membran (4, 10), wobei ein Ende des Kolbens (6) an der ersten Balg-artigen Membran (4) angebracht ist und das andere Ende des Kolbens (6) an der zweiten Balg-artigen Membran (10) angebracht ist um entsprechend den ersten und zweiten ringartigen Raum (a) zu bilden, nämlich einen ersten ringförmigen Raum (a) zwischen der Außenseite der ersten Balg-artigen Membran (4) und der Innenwand des Pumpenzylinders (5) und einen zweiten ringförmigen Raum (a) zwischen der Außenseite der zweiten Balg-artigen Membran (10) und der Innenwand des Pumpenzylinders (5), wobei der erste und zweite ringförmige Raum (a) unabhängig voneinander sind und der Druck der Flüssigkeit im ersten ringförmigen Raum (a) unabhängig ist vom Druck der Flüssigkeit im zweiten ringförmigen Raum (a).
  2. Eine Vorrichtung nach Anspruch 1, wobei der Kolben (6) verschiebbar in einem Dichtungselement (7) angebracht ist welches innerhalb des mittleren Teils der Innenseite des Zylinders (5) befestigt ist.
  3. Eine Vorrichtung nach Anspruch 1 oder 2, wobei der Außendurchmesser des Kolbens (6) dem Medianwert des wirksamen Durchmessers der ersten und zweiten Balg-artigen Membran (4, 10) entspricht.
  4. Eine Vorrichtung nach Anspruch 1, 2 oder 3, wobei der während des Betriebs das Volumen des ersten und zweiten Raumes (a) im Wesentlichen konstant bleibt.
  5. Eine Vorrichtung nach einem der vorstehenden Ansprüche, welche Mittel für das automatische Umstellen eines Ventils (102) enthält um die Zufuhr von Hydraulikflüssigkeit zum Hydraulikzylinder zu gegebenen Zeitpunkten der Arbeitszyklen der Vorrichtung zu kontrollieren, wobei besagte Mittel zur Umstellung des Ventils einen hydromechanischen Schalter enthalten, welcher enthält:
    - eine Kopplung (108,109) um die Linearbewegung des besagten Vorrichtungsteils (106) in Rotationsbewegung zu konvertieren;
    - eine Nocke (103) drehbar angetrieben durch besagte Kopplung (105, 109); und
    - eine Feder (115) dergestalt angebracht dass sie zusammengedrückt werden kann um Energie durch die Rotation der Nocke während eines Arbeitshubes des besagten Vorrichtungsteil (106) zu speichern, und dergestalt angebracht um ihre gespeicherte Energie freizusetzen um besagtes Ventil (102) umzustellen um die Zufuhr von Hydraulikflüssigkeit zum Hydraulikzylinder (107) der Vorrichtung zu kontrollieren wenn besagtes Teil (106) sich zu gegebenen Positionen entlang des Hydraulikzylinders (107) befindet, d.h. um den Arbeitszyklus der Vorrichtung zu kontrollieren.
  6. Die Vorrichtung nach Anspruch 5, wobei die Feder (115) eine Druckfeder ist die auf einem Arm (150) angebracht istder von der Nocke (103) erstreckt in der Art dass bei Rotationsbewegung der Nocke (103) durch die Verbindung (108, 109) das zur Nocke benachbarte Ende der Feder zusammengedrückt wird bis die Feder einen instabilen Gleichgewichtspunkt "A" erreich, ab dem die Feder ihre gespeicherte Energie freisetzt um besagtes Ventil (102) umzustellen.
  7. Die Vorrichtung nach Anspruch 6 oder 7, wobei, wenn die Feder ihre gespeicherte Energie freisetzt, dies zuerst kurzzeitig die Nocke (103) antreibtund nachdem die Nocke einen gegebenen Winkel durchlaufen hat, die Nocke (103) einen Teil zum Umstellen des Ventils (102) dreht.
  8. Die Vorrichtung nach Anspruch 5, 6, oder 7, wobei besagte Verbindung (109) angeordnet ist um die Nocke um einen Winkel von weniger als 180° für jeden Arbeitshub des besagten Vorrichtungsteils (106) zu drehen.
  9. Die Vorrichtung gemäß einem der Ansprüche 5 bis 8, wobei die Verbindung (108, 109) eine Schneckengetriebekopplung ist welche eine Mutter (108) und eine Gewindestange (109) enthält.
