The filter cartridge (1) is fitted loosely on a mandrel (3) having a central axial bore (4) and radial bores (5). The mandrel extends through the filter housing (2) and has a polygonal end (6), which fits in the housing (2). The mandrel end has a screw connector (12) which, on screwing together, presses the filter housing (2) tightly against the top plate (9), fitted with seals (7, 8), and clamps the filter cartridge (1). ADVANTAGE - The filter is inexpensive and can be disposed of safely.

Description

Die Erfindung betrifft einen Spin-On-Ölfilter ins­ besondere für Verbrennungsmotoren, zum Anschrauben an den Motorblock, bestehend aus Filterpatrone, Kopfplatte und Filtergehäuse.The invention relates to a spin-on oil filter especially for internal combustion engines, to screw on to the engine block, consisting of a filter cartridge, Head plate and filter housing.

Spin-On-Ölfilter gattungsgemäßer Art finden insbe­ sondere bei zum Antrieb von Kraftfahrzeugen einge­ setzten Verbrennungsmotoren Verwendung. Sie haben die Aufgabe, etwaige in das Motoröl gelangte Verun­ reinigungen auszufiltern und so das Motoröl sau­ berzuhalten und damit einerseits Beschädigungen des Motors durch - auch sehr kleine - Partikel und an­ dererseits ein Verstopfen der zur Schmierung beweg­ licher Motorteile dienenden Ölbohrungen zu verhin­ dern.Spin-on oil filters of the generic type are found in particular especially turned on for driving motor vehicles put internal combustion engines use. They have the task of getting Verun into the engine oil filter out cleaning and so the engine oil clean maintain and thus damage the Motors through - even very small - particles and on on the other hand, a blockage that moves for lubrication to prevent oil holes serving engine parts other.

Dazu werden die gattungsgemäß aus Filterpatrone und Filtergehäuse bestehenden Spin-On-Ölfilter am Mo­ torblock angeschraubt und mit Erreichen der Höchst­ benutzungsdauer abgeschraubt und durch Neufilter ersetzt. Bei Spin-On-Ölfiltern im Stande der Tech­ nik sind Filterpatrone und Filtergehäuse nicht trennbar. Der Ölfilter wird daher stets Restmengen an Altöl enthalten, seine Entsorgung ist damit im Hinblick auf zu vermeidende Umweltbelastungen pro­ blematisch. Hinzu kommt, daß durch den Austausch des Gesamtfilters das zur Herstellung des Filterge­ häuses verwendete Material in der Regel verloren geht. Dies ist einerseits im Hinblick auf den gebo­ tenen sparsamen Umgang mit Rohstoffen, andererseits auf die zwangsläufig entstehenden vergleichsweise hohen Kosten ungünstig.For this purpose, the filter cartridge and Filter housing existing spin-on oil filter on Mon screwed on and when reaching the top unscrewed service life and new filter replaced. With spin-on oil filters in the state of the art The filter cartridge and filter housing are not nik separable. The oil filter is therefore always left over contain waste oil, so its disposal is in the With regard to environmental pollution to be avoided per blemish. Add to that through the exchange of the overall filter for the manufacture of the filter material used in the home is usually lost goes. On the one hand, this is with regard to the gebo  efficient use of raw materials, on the other hand comparative to the inevitably arising high cost unfavorable.

Die Erfindung hat es sich daher zur Aufgabe ge­ macht, einen Spin-On-Ölfilter zu schaffen, dessen Entsorgung unter Umweltaspekten unproblematisch und dessen Benutzung kostengünstiger ist.The invention is therefore ge task to create a spin-on oil filter whose Disposal without problems from an environmental point of view its use is cheaper.

Diese Aufgabe wird erfindungsgemäß durch einen Spin-On-Ölfilter mit den Merkmalen des Kennzeichens des Anspruches 1 gelöst.This object is achieved by a Spin-on oil filter with the characteristics of the mark of claim 1 solved.

Die mit der Erfindung erzielbaren Vorteile sind vielfältig. Durch Lösen der Schraubverbindung kann die Kopfplatte evtl. mit Dorn entfernt, die Filter­ patrone entnommen und das im Filtergehäuse befind­ liche Restöl entleert werden. Sodann kann eine neue Filterpatrone eingesetzt und die Kopfplatte durch Zusammenschrauben wieder befestigt werden. Der Fil­ ter in zusammengeschraubtem Zustand läßt sich wie ein herkömmlicher nicht zerlegbarer Spin-On-Ölfil­ ter an den Motorblick anschrauben. Der bei den mei­ sten Verbrennungsmotoren in regelmäßigen Interval­ len erforderliche Wechsel des gesamten Ölfilters wird bei Verwendung der erfindungsgemäßen zerlegba­ ren Spin-On-Filter durch ein bloßes Wechseln der Filterpatrone ersetzt, die in der Regel äußerst ko­ stengünstig aus vergleichsweise reichlich vorhan­ denen Rohstoffen, wie zum Beispiel Papier oder tex­ tilem Material, herzustellen ist. Entscheidend ist, daß wie bei herkömmlichen Spin-On-Ölfiltern beim Auf- oder Abdrehen des Filters dieser in sich sta­ bil bleibt. The advantages that can be achieved with the invention are diverse. By loosening the screw connection the head plate may be removed with a thorn, the filters cartridge removed and located in the filter housing residual oil can be emptied. Then a new one Filter cartridge inserted and the head plate through Screwed together again. The fil ter screwed together can be like a conventional spin-on oil film that cannot be dismantled Screw on to the motor view. The one with mei most internal combustion engines at regular intervals len required replacement of the entire oil filter is using the zerlegba spin-on filter by simply changing the Filter cartridge replaced, which is usually extremely ko inexpensive from comparatively abundant those raw materials, such as paper or tex tilem material to manufacture. It is crucial that like conventional spin-on oil filters with Unscrew or unscrew the filter bil remains.  

In einer vorteilhaften Ausbildung der Erfindung ist bevorzugt, daß die Schraubverbindung zum Festlegen des Gehäuses aus einer Mutter und/oder einer Schraube besteht.In an advantageous embodiment of the invention preferred that the screw connection for fixing the housing from a nut and / or Screw exists.

Die Verwendung derartiger in der Technik lange er­ probter Schraubverbindungen ermöglicht in vorteil­ hafter Weise die Verwendung herkömmlicher ferti­ gungstechnischer Anlagen sowie das Zerlegen des Filters mit bereits jedem Laien zur Verfügung ste­ hender Mittel (Schraubenschlüssel).He has long used such in the art Proven screw connections in advantage the use of conventional ferti technical systems and the disassembly of the Filters are available with every layperson means (wrench).

Besonders bevorzugt ist es, den Dorn und die Kopf­ platte einstückig auszuführen.It is particularly preferred to use the mandrel and the head plate in one piece.

Auch hier stehen fertigungstechnische Überlegungen im Vordergrund. Bei einstückiger Ausführung dieser Teile entfällt ein Zusammensetzen. Zudem wird die Stabilität dieser für den erfindungsgemäßen Filter entscheidenden Teile bei einstückiger Ausführung erhöht.Here too there are manufacturing considerations in the foreground. With a one-piece version of this Parts do not have to be assembled. In addition, the Stability of these for the filter according to the invention crucial parts in one-piece execution elevated.

Um die Montage weiter zu vereinfachen, wird außer­ dem vorgeschlagen, den Dorn mit einer Anschlagsflä­ che und/oder einem Filterspannelement zu versehen. Bei einer derartigen Ausgestaltung der Erfindung wird die Montage erleichtert und Montagefehler wer­ den zuverlässig vermieden.To further simplify assembly, who proposed the mandrel with a stop surface che and / or to provide a filter clamping element. In such an embodiment of the invention assembly is made easier and assembly errors that reliably avoided.

Zuletzt ist daran gedacht, das Filtergehäuse mit Kühlrippen zu versehen.Finally, the filter housing is thought of To provide cooling fins.

Bei den meisten modernen Verbrennungsmotoren ist die Öltemperatur, die die Viskosität des verwende­ ten Motoröls beeinflußt, für die Motorfunktion von entscheidender Bedeutung. Nicht wenige Motoren - vor allem Hochleistungsmotoren - sind aus diesem Grund mit Ölkühlern versehen. Mindestens ein Teil dieser Kühlfunktion kann bei der erfindungsgemäßen Ausgestaltung durch die am Ölfilter angebrachten Kühlrippen verstärkt oder mit übernommen werden.With most modern internal combustion engines the oil temperature that the viscosity of the use engine oil affected for the engine function of  vitally important. Quite a few engines - especially high-performance engines - are from this Bottom provided with oil coolers. At least part of it this cooling function can in the invention Design by the attached to the oil filter Cooling fins can be reinforced or taken over.
