Description
Die Erfindung betrifft ein Filter, das ein Verschmutzen von Druckmeßgeräten verhütet. The invention relates to a filter which prevents contamination of pressure gauges prevent.
Beim Messen des. Kompressionsdruckes an Verbrennungsmotoren, des erzielten Druckes an Kompressoren, Pumpen u. dgl. muß das Eindringen von Schmutz und Fremdkörpern in die Druckmeßgeräte verhindert werden, um ein einwandfreies Arbeiten der Geräte zu gewährleisten. When measuring the. Compression pressure on internal combustion engines, des The pressure achieved on compressors, pumps and the like must prevent the ingress of dirt and foreign objects in the pressure gauges are prevented to work properly of the devices.
Es sind Filter und Filtereinsätze, die nach verschiedenen Prinzipien arbeiten, bekannt. Diese Filter werden als selbständiges Teil angefertigt und vor die Druckmeßgeräte montiert, oder es werden an geeigneter Stelle Filtereinsätze eingebaut. There are filters and filter cartridges that operate according to different principles work, known. These filters are made as a separate part and before the pressure gauges are installed, or filter inserts are installed at a suitable point built-in.
Das Herstellen der selbständigen Filter und Filtereinsätze verursacht erhebliche Kosten. Creating independent filters and filter cartridges creates significant cost.
Die Erfindung betrifft eine Anordnung eines Siebfilters in einem Anschlußnippel oder in einem anderen Teil der Druckmeßeinrichtung. Diese Anordnung vermindert die bisher notwendigen Kosten weitestgehend. The invention relates to an arrangement of a sieve filter in one Connection nipple or in another part of the pressure measuring device. This arrangement reduces the costs previously necessary as much as possible.
In der Abbildung ist ein Beispiel der Anordnung gezeigt. Ein handelsübliches, dünnmaschiges Sieb a wird zwischen zwei handelsüblichen Sieben b und c, die eine größere Maschenweite und eine größere Drahtstärke besitzen, durch ein Stuck eines handelsüblichen Rohres d, das in die abgesetzte Bohrung eines Anschlußnippels e eingepreßt ist, festgehalten. Das dünnmaschige Sieb a stellt das Filter dar, das Sieb b dient zur festigkeitsmäßigen Verstärkung des Siebes a, während das Sieb c Fremdkörper, die das Sieb a beschädigen würden, zurückhält. An example of the arrangement is shown in the figure. A commercially available, thin-mesh sieve a is between two commercially available sieves b and c, the one Have a larger mesh size and a larger wire size, through a piece of a commercial pipe d, which e is pressed in, held. The thin-mesh sieve a represents the filter that Sieve b is used to strengthen the strength of the sieve a, while the sieve c Holds back foreign bodies that would damage the sieve a.
