Abstract

Die Erfindung betrifft eine Vorrichtung zum berüh­ rungslosen Dosieren von Flüssigkeiten, die als Dosiersprit­ ze ausgestaltet ist. Sie besitzt einen zentral in einer Hülse (8) angeordneten Kolben (5), um den eine Feder (6) ange­ ordnet ist. Die Feder (6) liegt mit ihrem einen Ende am Boden der Hülse (8) und mit ihrem anderen Ende an der Rückseite eines Zylinders (4), der Teil eines die Flüssigkeit autnehmenden Körpers (1) ist. Die Hülse (8) umgreift das Ende des Zylinders (4). Für die Hubbegrenzung sind An­ schläge (10, 13) auf der Außenseite des Zylinders (4) vorge­ sehen. The invention relates to a device for touch smooth dosing of liquids as dosing fuel ze is designed. It has one centrally in a sleeve (8) arranged piston (5) around which a spring (6) is attached is arranged. The spring (6) is at one end Bottom of the sleeve (8) and with its other end on the Back of a cylinder (4), the part of a the liquid accepting body (1). The sleeve (8) encompasses this End of the cylinder (4). For the stroke limitation are On strokes (10, 13) on the outside of the cylinder (4) pre see.
