Abstract

Um ein Dosiergerät oder Titriergerät, insbesondere eine Bürette, zu schaffen, mit denen eine kontinuierliche Förderung der Flüssigkeit möglich ist, wird eine kontinuierlich fördernde Pumpe vorgeschlagen, die mehrere Kolben (6, 8) und eine Ventilsteuereinrichtung, vorzugsweise eine Ventilscheibe (22), aufweist. Die Kolben (6, 8) sind durch eine Antriebseinrichtung, vorzugsweise eine Welle (9) in ihren jeweiligen Zylindern (2, 4) derart hin- und herbewegbar, daß einer bestimmten Bewegung der Antriebseinrichtung bzw. Drehung der Welle (9) jeweils dieselbe Fördermenge der Pumpe entspricht. Die Ventilsteuereinrichtung bzw. Ventilscheibe (22) steht mit der Antriebseinrichtung bzw. Welle (9) in Wirkverbindung. Sie steuert die Saugleitungen (25, 27) und Druckleitungen (28, 30) der Zylinder (2, 4) .

In order to create a metering device or titration device, in particular a burette, with which a continuous delivery of the liquid is possible, a continuously delivering pump is proposed which has a plurality of pistons (6, 8) and a valve control device, preferably a valve disk (22) . The pistons (6, 8) can be moved back and forth in their respective cylinders (2, 4) by a drive device, preferably a shaft (9), in such a way that a certain movement of the drive device or rotation of the shaft (9) has the same delivery rate in each case corresponds to the pump. The valve control device or valve disk (22) is operatively connected to the drive device or shaft (9). It controls the suction lines (25, 27) and pressure lines (28, 30) of the cylinders (2, 4).
