Description
" Ii.''Beschreibung" Ii.''Description
Die Erfindung oeziem sich auf eine mechanische Dosierpumpe tue die Abfüllung kleinerer Mengen aus gröfjeren Behältnisse-.The invention relates to a mechanical dosing pump for filling smaller quantities from larger containers.
Dosierpuiipen sind seit Jahren bekannt und we^äsn insbesondere für medizinische Zweclce verwendet.Dosing pumps have been known for years and are used especially for medical purposes.
Es 9ibt Dispenser füj: Medizin- od«»r Laborzwecke, die sehr genau dosieröar sir«3 (auf l ml). Der~n Zylinderrohr besteht sus Glas and der KolDen ist teflonbeschichtet .There are dispensers for medical or laboratory purposes that allow very precise dosing (to 1 ml). The cylinder tube is made of glass and the piston is Teflon-coated.
Ein Nachteil der bisher verwendeten Dosierpumpen ist darin zu. sehen, daß die komplizierte Handhabung der Dosierung den Einsatz im täglichen Gebrauch wesentlich erschwert. Zudem ist eine derartige Dosierpumpe nur sehr schwer "srzustellen, weil aufgrund der hochwertigen Materialien eine Komplizierte Bearbeitung des Gegenstandes erforderlich ist.A disadvantage of the dosing pumps used to date is that the complicated handling of the dosing makes it much more difficult to use in everyday life. In addition, such a dosing pump is very difficult to manufacture because the high-quality materials require complicated processing of the object.
Der Erfindung liegt die Aufgabe zugrunde, die vorstehend genannten Nachteile für eine mechanische Dosierpumpe der eingangs genannten Art zu beseitigen, und eine Dosierpumpe zu schaffen, die einfach, in der Herstellung und in der Wirkungsweise ist.The invention is based on the object of eliminating the above-mentioned disadvantages for a mechanical metering pump of the type mentioned at the outset and of creating a metering pump which is simple in its manufacture and in its mode of operation.
Erreicht ist dieses Ziel dadurch, daß das Zylinderrohr (in aus klarem Poiyaaid (PA) besteht und somit die zur Dosierung erforderlichen Nocken und der Dosierring (13) einfach herzustellen sind und eine einfache Dosierungsinöglichkeit ergeben.This goal is achieved by the cylinder tube (in) being made of clear polyamide (PA) and thus the cams and the dosing ring (13) required for dosing are easy to manufacture and provide a simple dosing option.
In der Zeichnung 1 let der Erfindungsgegenstand im Längsschnitt dargestellt. Die Zeichnung 2 zeigt die Arrestiermarken und den Dosierring.Drawing 1 shows the subject matter of the invention in longitudinal section. Drawing 2 shows the locking marks and the dosing ring.
Die mechanische Dosierpumpe besteht aus dem Gehäuse <io>: dem Zylinderrohr dl); dem Lamellenkolben (14); dem Dicntetopfen (16); der Außenkappe (12j; der Druckfeder (15); dem Ventilgehäuse Einlaß (20); dem Ventilgehäuse Aus-The mechanical metering pump consists of the housing <io>: the cylinder tube dl); the lamellar piston (14); the sealing plug (16); the outer cap (12j; the compression spring (15); the valve housing inlet (20); the valve housing outlet-
laß (17J; der Druckfeder Ein- u. Auslaß (22); der Kugel Ein- u.. Auslaß C21); dem Dosierring (13); dem Ansaugrohr (19) und dem ÄDlaufronr d6J.inlet (17J; the compression spring inlet and outlet (22); the ball inlet and outlet C21); the metering ring (13); the intake pipe (19) and the oil flow ring d6J.
Mit dem außen auf dem Zyiinderrohr dl) montiertem Dosierring d3) Kann die gewünschte abzufüllende Menge von 5 ml bis 30 mi in Schritten von Ie 5 mi fixiert werden. Durch eine Bajonettrastung ist das aDzufuliende Medium einfach jnd schnell auf die gewünschte Menge einzustellen.The dosing ring d3) mounted on the outside of the cylinder tube d1) can be used to set the desired amount to be filled from 5 ml to 30 ml in increments of 10 ml. The medium to be filled can be set to the desired amount quickly and easily using a bayonet lock.
Das Zylinderrohr dl) ist außen mit einer Längs- und fünf Quernuten verii-.en, die auf eine Dosierung mit Einern Scnrittvoiumen von 5 nl ausgelegt sine. Das Zyimderrohr dl) ist pro Rastung mit einer Inmitsangaae von 5 / 10 / 15 / 20 /25 / 3(1 ml versehen.The cylinder tube dl) is provided with one longitudinal and five transverse grooves on the outside, which are designed for dosing with a step volume of 5 nl . The cylinder tube dl) is provided with a volume indication of 5 / 10 / 15 / 20 / 25 / 3(1 ml per stop.
Der Dosierring (13) ist ein außen geriffelter 7,5 mm breiter Ring mit ?wei innen liegenden 7, 5x3, 5 mm starken Noc'/en. Dieser Ring wird außen üDer das Zylinderrohr geschoben und mit den innenliegenden Nocken deckungsgleich in die beiden Längsnuten am Zylinderrohr dl) eingefünrt.The dosing ring (13) is a 7.5 mm wide ring with grooves on the outside and two 7.5 x 3.5 mm thick cams on the inside. This ring is pushed over the outside of the cylinder tube and inserted with the cams on the inside into the two longitudinal grooves on the cylinder tube (d1) so that they are congruent.
Durch eine kurze Rechtsdrehung wird der Ring in die jeweiligen Quernuten eingerastet. Je nach Rastung wird somit das Pumpvolumen der Pumpe festgelegt, da die Außenkappe mit dem Kolben verbunden ist und der Dosierweg zwischen Außenkappe und Dosierring begrenzt wird. Der Dosierweg wird durcn das Ausdrücken mit der Unterseite der Kappe auf den Dosierring begrenzt. Der Kolben wird mittels Außenkappe nacr» unten gedruckt, die Kappe wird losgelassen, die Pumpe füllt sich durch die montierte Druckfeder, der Kolben bewegt sich wieder nach oben, aer Pumpenzylinder ist somit gefüllt, das Volumen isv: erreicht.By turning it briefly to the right, the ring is locked into the respective transverse grooves. The pump volume of the pump is determined depending on the locking position, since the outer cap is connected to the piston and the dosing path is limited between the outer cap and the dosing ring. The dosing path is limited by pressing the underside of the cap onto the dosing ring. The piston is pressed downwards using the outer cap, the cap is released, the pump fills up using the mounted pressure spring, the piston moves upwards again, the pump cylinder is thus filled, the volume is reached.
Die so hergestellte Dosierpumpe bietet im Gegensatz zu den bisnerigen Pumpen eine einfachere Handhabung, insbesondere itt «in Schrauben wegen der Balonettraatung nicht notwendig. Zudem ist der Kostenaufwand relativ gering. In contrast to the pumps used up to now, the dosing pump manufactured in this way is easier to handle, especially since screws are not necessary due to the balloon coating. In addition, the costs are relatively low.
