Description
Flüssigkeitsmeßvorrichtung mit frei fliegendem Kolben Bei Meßvorr ichtungen mit frei fliegendem Kolben, wie sie schon beschrieben worden sind, besteht, wenn :der Zylinder vertikal angeordnet ist, der Nachteil, daß nach Beendigung eiiler Meßzapfung in der Hochlage des Kolbens dieser, sofern er nicht absolut dicht ist, nach und nach herabsinkt, so daß beim Wiederbeginn der Zapfung der Kolben eine ungenaue Stellung hat und die Abgabe einer dem vollen Hube entsprechenden Menge .nicht möglich ist.Liquid measuring device with free-flying piston seals with free-flying piston, as they have already been described, exist, when: the cylinder is arranged vertically, the disadvantage that after termination it is faster Measuring tap in the high position of the piston, if it is not absolutely tight, gradually descends, so that when the tapping of the piston starts again an inaccurate Position and the delivery of an amount corresponding to the full stroke is not possible is.
Dieser Übelstand wird gemäß der Erfindung dadurch behoben, daß der Kolben einen doppelkonischen Dorn trägt, der @in eine Sprengfeder eingeführt wird derart, daß .in der oberen Endlage .des Kolbens idie Sprengfeder den Kolben festhält und sogar gegen die Hubbegrenzungsfläche anpreßt. An der Unterseite des Kolbens ;ist eine derartige Maßnahme nicht nötig, weil das Schwergericht des Kolbens die richtige Stellung sichert.This drawback is remedied according to the invention in that the Piston carries a double-conical mandrel which is inserted into a coil spring in such a way that .in the upper end position of the piston i the coil spring holds the piston in place and even presses against the stroke limit surface. At the bottom of the piston ; such a measure is not necessary, because the difficult judgment of the piston is the secures correct position.
In den Figuren ist eine .derartige Einrichtung im Schnitt und einer Ansicht dargestellt.In the figures, one. Such a device is in section and one View shown.
Der Meßzylinder z enthält einen Kolben 2, welcher auf dem Boden 3 seine untere Hubbegrenzung findet, während .die obere Hubbegrenzung durch den konischen Dorn 4 des Kolbens hei seinem Anschlag an den Vorsprung 5 des Deckels 6 des Meßzylinders erzielt wird. Am Deckel 6 ist eine Sprengfeder 7 angebracht.The measuring cylinder z contains a piston 2 which rests on the bottom 3 its lower stroke limitation takes place, while the upper stroke limitation is through the conical Mandrel 4 of the piston is hot when it hits the projection 5 of the cover 6 of the measuring cylinder is achieved. A coil spring 7 is attached to the cover 6.
Die Wirkungsweise der Einrichtung ist folgende: Sobald der Kolben bei der entsprechenden Halmstellung nach oben gedrückt wird, wird der komische Dorn. q. @durch ,die Sprengfeder 7 hindurchgedrängt, die sich jetzt gegen die hintere Einschnürung 8 - des Kolbens anlegt und diesen nicht nur in der Lage des Hubendes festhält, sondern .ihn sogar gegen den Anschlag 5 dauernd ein wenig anpreßt. Hierdurch wird vermieden, daß der Kolben in der Ruhelage der Meßvorrichtung, sofern er ein wenig undicht ist, nach und nach herabsinkt und dabei eine ungenaue Stellung einnimmt.The operation of the device is as follows: As soon as the piston is pushed upwards when the stalk is in the appropriate position, it becomes the strange thorn. q. @ pushed through the coil spring 7, which is now against the rear Constriction 8 - of the piston and not only in the position of the end of the stroke holds, but .ihn even constantly presses a little against the stop 5. Through this it is avoided that the piston in the rest position of the measuring device, provided that it is a there is little leakage, gradually sinks down and assumes an imprecise position.
