Abstract
Description
Die Erfindung betrifft ein Stützrohr für einen Ölfilter, insbesondere einen Hydraulikölfilter, das mit mehreren Durchtrittsöffnungen für den Durchfluss von Öl bei der Filterung versehen ist.The invention relates to a support tube for an oil filter, in particular a hydraulic oil filter, which is provided with a plurality of passages for the flow of oil in the filtering.
Solche durch Benutzung bekannten Stützrohre tragen in den Ölfiltern ein als Faltenbalg ausgebildetes Filterelement. Das Stützrohr weist kreisrunde oder schlitzförmige Öffnungen auf, durch die beim Filtern das Öl dringt.Such known by use support tubes carry in the oil filters designed as a bellows filter element. The support tube has circular or slot-shaped openings through which the oil penetrates during filtering.
Der Erfindung liegt die Aufgabe zugrunde, das Stützrohr mit einer gut erkennbaren Kennzeichnung zu versehen.The invention has for its object to provide the support tube with a well-recognizable label.
Das diese Aufgabe lösende Stützrohr nach der Erfindung ist dadurch gekennzeichnet, dass mittels der Durchtrittsöffnungen auf dem Stützrohr ein sichtbares Zeichen gebildet ist.The task solving support tube according to the invention is characterized in that by means of the passage openings on the support tube a visible sign is formed.
Vorteilhaft lässt sich das Stützrohr auf einfache Weise mit dem Zeichen versehen, das eine Schrift, die z. B. den Namen eines Herstellers, eine Typenbezeichnung oder eine Kodierung wiedergibt, oder ein Bild, z. B. ein Firmenlogo, sein kann und bei Betrachtung des Stützrohrs, z. B. bei einem Filterwechsel, einfach zu erkennen ist.Advantageously, the support tube can be provided in a simple manner with the sign, the font, the z. Example, the name of a manufacturer, a type designation or a coding reproduces, or a picture, for. B. a company logo, can be and when viewing the support tube, z. B. at a filter change, easy to recognize.
Das Stützrohr wird bereits während seiner Herstellung beim Stanzen der Durchtrittsöffnungen in ein das Stützrohr bildendes Blech, mit dem Zeichen versehen. Zur Kennzeichnung des Stützrohrs ist ein zusätzlicher Verfahrensschritt wie das Aufbringen einer Beschriftung oder dergleichen nicht notwendig.The support tube is already provided during its production in punching the passage openings in a support tube forming sheet metal, with the sign. For the identification of the support tube, an additional process step such as the application of a label or the like is not necessary.
In einer besonders bevorzugten Ausgestaltung der Erfindung sind die Durchtrittsöffnungen zur Bildung des Zeichens in verschiedenen Formen, vorzugsweise rund, oval, rechteckig, quadratisch, dreieckig, sternförmig und/oder schlitzförmig, und/oder in verschiedenen Größen vorgesehen.In a particularly preferred embodiment of the invention, the passage openings for forming the sign in various shapes, preferably round, oval, rectangular, square, triangular, star-shaped and / or slit-shaped, and / or provided in different sizes.
Das Zeichen kann ferner durch eine unterschiedliche Ausrichtung der Durchtrittsöffnungen auf dem Stützrohr erkennbar gemacht werden, z. B. durch vertikale und horizontale Ausrichtung der schlitzförmigen oder der ovalen Durchtrittsöffnungen.The sign can also be made recognizable by a different orientation of the passage openings on the support tube, z. B. by vertical and horizontal orientation of the slot-shaped or oval openings.
Alternativ oder ergänzend dazu kann das Zeichen, insbesondere auch bei gleich großer Form, Größe und Ausrichtung sämtlicher Durchtrittsöffnungen, dadurch gebildet sein, dass die Durchtrittsöffnungen derart auf dem Stützrohr angeordnet sind, dass sie optisch unterscheidbare Muster bilden. Die Muster sind vorzugsweise dadurch gebildet, dass die Durchtrittsöffnungen rasterartig in regelmäßigen Abständen auf dem Stützrohr angeordnet sind. Durch über die Mantelfläche des Rohrs gesehen unterschiedliche Gestaltungen der Durchtrittsöffnungen oder durch ihre Anordnung in unterschiedlichen Mustern lassen sich auf dem Stützrohr Linien oder Flächen darstellen, die das Zeichen bilden.Alternatively or additionally, the character, in particular even with the same size, size and orientation of all openings, be formed by the passage openings are arranged on the support tube so that they form optically distinguishable pattern. The patterns are preferably formed in that the passage openings are arranged like a grid at regular intervals on the support tube. Seen through the lateral surface of the tube different configurations of the passages or by their arrangement in different patterns can be on the support tube lines or surfaces that form the sign.
In einer weiteren Ausgestaltung der Erfindung ist auf einem Flächenabschnitt des Stützrohrs, auf dem das Zeichen gebildet ist, durch die Durchtrittsöffnungen dieselbe Durchflussfläche gebildet ist wie auf dem restlichen Stützrohr. Vorteilhaft wird die Funktion des Stützrohrs durch die erfindungsgemäße Kennzeichnung nicht verändert. Die Durchtrittsfläche pro Flächeneinheit ist über die gesamte Stützrohrfläche im Wesentlichen konstant.In a further embodiment of the invention is formed on a surface portion of the support tube on which the sign is formed through the passage openings through the same flow area as on the rest of the support tube. Advantageously, the function of the support tube is not changed by the marking according to the invention. The passage area per unit area is substantially constant over the entire support tube surface.
Die Erfindung wird nachfolgend anhand von Ausführungsbeispielen und der beiliegenden, sich auf diese Ausführungsbeispiele beziehenden Zeichnungen näher erläutert. Es zeigen:The invention will be explained in more detail with reference to embodiments and the accompanying drawings relating to these embodiments. Show it:
