Abstract

A device for determining the characteristics of a fluid jet emerging from a nozzle (12) consists of a capacitor (K). When the jet passes through this capacitor, the dielectric constant of the capacitor changes, and the resultant change and measurement of the charge voltage allow conclusions to be drawn about the characteristic of the jet. Suitable constructions of capacitors make it possible to determine correctly the direction, the vibration characteristic and the consistency of the jet, for example of the fuel jet emerging from an injection nozzle. <IMAGE>

The change in the charge voltage can be as Provide information about the nature of the jet, for example how high it should be Proportion of liquid and air.

Der Kondensator nach Figur 2 besteht anstatt aus zwei flachen Scheiben aus zwei konzentrisch zueinander in derselben Ebene angeordneten kurzen Rohrstücken 14, 15, die ebenfalls einen konstanten Abstand d zueinander aufweisen.The capacitor according to FIG. 2 consists instead of two flat disks of two short pieces of pipe arranged concentrically to one another in the same plane 14, 15, which also have a constant distance d from one another.

Die elektrische Verbindung 15 führt durch einen am Eohrstück 15 angeordneten Isolationskörper 17. Das elektrische Symbol dieses Kondensators ist in Figur 2 dargestellt und ist identisch mit demjenigen nach Figur 1. Auf eine Anwendung eines solchen bzw. modifizierten Kondensators ist veiter unten eingegangen.The electrical connection 15 leads through an arranged on the earpiece 15 Insulating body 17.

Der Kondensator K besteht uiederum aus einem äußeren Rohrstück 23 und vier konzentrischen, in derselben Ebene liegenden und zueek-Qãßigerveise gleich großen konzentrisch angeordneten Rohrsegmenten 24 bis 27, die einander nicht berühren, aber konstanten Abstand zum äußeren Rohrstück 23 haben Das elektrische Symbol für diesen Kondensator ist in Figur 4a dargestellt. Die einzelnen Rohrsegmente weisen jeweils einen eigenen elektrischen Anschluß wie bein Ausführungsbeispiel nach Figur 2 auf. Anstatt vier inneren Segmenten können natürlich auch nur zwei oder drei vorgesehen sein.The exemplary embodiment is particularly well suited for beam measurement according to FIG. 4. The capacitor K in turn consists of an outer pipe section 23 and four concentric, lying in the same plane and similar to the same large concentrically arranged pipe segments 24 to 27 that do not touch each other, but have a constant distance from the outer pipe section 23. The electrical symbol for this capacitor is shown in Figure 4a. The individual pipe segments have each with its own electrical connection as in the exemplary embodiment according to FIG 2 on.
