Description

Die Erfindung betrifft eine Baueinheit, bestehend aus mindestens einer Filter-, einer Pumpen- und einer Kühleinheit, die über ein Anschlußmodul fluidführend verbindbar und an eine Tankeinheit anschließbar sind, wobei das Anschlussmodul bei angeschlossener Tankeinheit mit einer Ansaugöffnung zusammen mit der Kühleinheit in das Innere der Tankeinheit mündet, und wobei die Filter- und die Pumpeneinheit außerhalb der Tankeinheit angeordnet sind.The invention relates to a structural unit, comprising at least one filter, a pump and a cooling unit, the fluidführend connected via a connection module and can be connected to a tank unit, wherein the connection module with connected tank unit with a suction together with the cooling unit in the interior of the Tank unit opens, and wherein the filter and the pump unit are arranged outside the tank unit.

Eine derartige Baueinheit ist aus US 3,720,260 bekannt. Die bekannte Baueinheit weist einen Wärmetauscher auf, der außerhalb, insbesondere auf einer Deckelplatte, der Tankeinheit angeordnet ist und neben einer Temperaturmesseinheit eine Wasserflusssteuerventileinheit aufweist. Dadurch, dass das Anschlußmodul bei angeschlossener Tankeinheit mit einer Ansaugöffnung zusammen mit der Kühleinheit in das Innere der Tankeinheit mündet und dass die Filter- und die Pumpeneinheit außerhalb der Tankeinheit angeordnet sind, läßt sich die Baueinheit auf eine Tankeinheit, beispielsweise in Form eines Ölbehälters, aufsetzen und mit dieser verbinden, wobei die Kühleinheit in das Innere der Tankeinheit hineinragt. Demgemäß ragt gleichfalls die Ansaugöffnung in das Innere des Tanks und ermöglicht dergestalt über die Pumpeneinheit eine fortlaufende Entnahme des in der Tankeinheit bevorrateten Fluids. Die sonstigen Einheiten (Filter- und Pumpeneinheit) sind außerhalb der Tankeinheit gut zugänglich angeordnet und durch das direkte Aufsetzen und den Eingriff der Baueinheit auf bzw. in die Tankeinheit ist eine Verrohrung in Form von Fluidleitungen zwischen Baueinheit und Tankeinheit vermeidbar.Such a unit is made US 3,720,260 known. The known structural unit has a heat exchanger, which is arranged outside, in particular on a cover plate, of the tank unit and has a water flow control valve unit in addition to a temperature measuring unit. Characterized in that the connection module with connected tank unit with a suction opening together with the cooling unit into the interior of the tank unit and that the filter and the pump unit are arranged outside the tank unit, the assembly can be a tank unit, for example in the form of an oil tank, put on and connect with this, wherein the cooling unit projects into the interior of the tank unit. Accordingly, the suction opening also protrudes into the interior of the tank and thus enables the pump unit to continuously remove the fluid stored in the tank unit. The other units (filter and pump unit) are arranged easily accessible outside the tank unit and by the direct placement and engagement of the unit on or in the tank unit piping in the form of fluid lines between the unit and tank unit can be avoided.

Durch die WO 98/42986 A1 ist eine Fluid-Kühlvorrichtung als Baueinheit mit einem Motor bekannt, der ein Lüfterrad sowie eine Fluidpumpe antreibt, die Fluid aus einem Ölbehälter nimmt und in einen hydraulischen Arbeitskreis fördert, der das Fluid erwärmt, sowie zu einem Wärmetauscher (Kühleinheit) führt, aus dem das Fluid gekühlt in den Ölbehälter zurückkehrt, wobei der Ölbehälter wannenförmig ausgebildet ist und mit hochgezogenen Wannenrändern in der Art einer Halbschale zumindest den Motor und die Fluidpumpe teilweise umfaßt. Mit der bekannten Lösung ist es möglich, die eigentliche Baueinheit, bestehend aus einer Filter-, einer Pumpen- und einer Kühleinheit platzsparend mit einem relativ großvolumig aufbauenden Ölbehälter als Tankeinheit zu verbinden, wobei ausgehend von dem von den Wannenrändern des Ölbehälters freigelassenen Bauraum eine gute Zugänglichkeit der sonstigen Baueinheit zu Montage- und Wartungzwecken gewährleistet ist. Die bekannte Fluid-Kühlvorrichtung vermeidet weitestgehend eine zusätzliche Verrohrung, was zum einen Kosten sparen hilft und zum anderen ist ein dahingehender Aufbau energetisch günstig, weil dergestalt Verluste in den Fluidleitungen vermieden sind. Unabhängig hiervon ist es aber grundsätzlich so, dass die bekannte Fluid-Kühlvorrichtung nur als Gesamt-Baueinheit, bestehend aus der Kombination von Filter-, Pumpen-, Kühl- und Tankeinheit, veräußerbar ist und insbesondere ein Nachrüsten an bereits bestehende Ölbehälter oder Tankeinheiten mit der sonstigen Baueinheit kaum möglich ist. Da dahingehende Tank- und Ölbehältereinheiten häufig aus anderen Herstellerbetrieben stammen und bereits vor Ort sind, wäre es aber in Abhängigkeit des jeweiligen Anwendungsfalles wünschenswert, dahingehende Einheiten mit einer Baueinheit, bestehend aus einer Filter-, einer Pumpen- und einer Kühleinheit entsprechend nachzurüsten oder gegebenenfalls Umbauten dergestalt vorzunehmen, dass die eine Fluid-Kühlvorrichtung gegen eine neue, beispielsweise mit größerer Leistung, ausgetauscht wird und dabei die jeweilige Behälter- oder Tankeinheit am Einsatzort verbleibt.By the WO 98/42986 A1 a fluid cooling device is known as a unit with a motor that drives a fan and a fluid pump that takes fluid from an oil reservoir and promotes in a hydraulic working circuit that heats the fluid, and leads to a heat exchanger (cooling unit), from which the Cooled fluid returns to the oil reservoir, wherein the oil reservoir is trough-shaped and with raised tub edges in the manner of a half-shell at least partially comprises the motor and the fluid pump. With the known solution, it is possible, the space-saving to connect the actual unit consisting of a filter, a pump and a cooling unit with a relatively bulky oil tank as a tank unit, starting from the released from the tub edges of the oil tank space a good accessibility the other assembly for assembly and maintenance purposes is guaranteed. The known fluid cooling device largely avoids an additional piping, which helps to save costs and on the other hand a pertinent structure is energetically favorable, because such losses in the fluid lines are avoided. Regardless of this, however, it is basically the case that the known fluid cooling device can only be sold as an overall unit consisting of the combination of filter, pump, cooling and tank unit, and in particular retrofitting to existing oil tank or tank units with the other unit is hardly possible. Since this tank and oil tank units often come from other manufacturers and are already on site, but it would be desirable depending on the particular application, pertinent units with a unit consisting of a filter, a pump and a cooling unit to retrofit or possibly conversions make such that the one fluid cooling device is replaced with a new, for example, with greater power, while the respective container or tank unit remains at the site.

Demgemäß ist es im Stand der Technik bekannt ( WO 01/18363 A1 ), Fluid-Kühlvorrichtungen als Baueinheit an getrennt hiervon vorgesehenen Ölbehältern oder Tankeinheiten anzuschließen. So betrifft die bekannte Lösung eine Fluid-Kühlvorrichtung mit in einer Baueinheit zusammengefaßter Kühl-, Filter- und Pumpeneinrichtung, wobei in einem Fluidkreislauf von der Pumpeneinrichtung gefördertes Fluid von der Filtereinrichtung filterbar und von der Kühleinrichtung kühlbar ist und wobei die Filtereinrichtung mindestens ein bei ihrer Verschmutzung auswechselbares Filterelement aufweist. Dadurch, dass bei der bekannten Lösung für einen Austausch des jeweiligen Filterelementes im Fluidkreislauf eine ansteuerbare Absperreinheit vorhanden ist, mit der die Filtereinrichtung von der Pumpeneinrichtung derart abtrennbar ist, dass die Kühleinrichtung weiter mit dem zu kühlenden Fluid versorgt ist, ist es bei der bekannten Lösung möglich, den angesprochenen Filterelement-Wechsel ohne zusätzlichen Aufwand auch dann zu ermöglichen, wenn die nachgeordnete Schmierölversorgung nicht abgestellt wird. Die bekannte Fluid-Kühlvorrichtung läßt sich als Baueinheit in Abhängigkeit ihres Leistungsvermögens mit beliebigen Ölbehältern oder Tankeinheiten verbinden, wobei hierfür jedoch eine entsprechende Verrohrung, sprich fluidführende Leitungen zwischen Baueinheit und Tankeinheit notwendig sind. Wie bereits dargelegt, ist dies herstell- und montagetechnisch mit einem entsprechenden Aufwand verbunden, was die Kosten erhöht und des weiteren kommt es aufgrund der Länge der vorgesehen Fluidleitungen zwischen Bau- und Tankeinheit zu Strömungswiderständen, was sich ungünstig auf einen energetisch sinnvollen Betrieb der Gesamt-Einrichtung auswirkt. Auch führen die zusätzlichen Fluidleitungen zu einem erhöhten Einbauraum, was häufig bei Anwendungen in der Fahrzeugtechnik sowie im Maschinen- und Apparatebau zu Problemen führt, wo häufig aufgrund vorgegebener Randbedingungen nur wenig Einbauraum gegeben ist.Accordingly, it is known in the art ( WO 01/18363 A1 ) To connect fluid cooling devices as a unit to separately provided therefrom oil tanks or tank units. Thus, the known solution relates to a fluid cooling device combined in a unit cooling, filtering and pumping device, wherein in a fluid circuit funded by the pump device fluid from the filter device and the cooling device can be cooled and the filter device at least one in their pollution having replaceable filter element. Characterized in that in the known solution for an exchange of the respective filter element in the fluid circuit a controllable shut-off unit is present, with which the filter device of the pump device is separable so that the cooling device is further supplied with the fluid to be cooled, it is possible in the known solution to allow the mentioned filter element change without additional effort, even if the downstream lubricating oil supply is not turned off. The known fluid cooling device can be connected as a unit depending on their performance with any oil tanks or tank units, but this requires a corresponding piping, ie fluid-carrying lines between the unit and tank unit necessary. As already stated, this is manufacturing and assembly technology associated with a corresponding effort, which increases the cost and further it comes due to the length of the fluid lines provided between the construction and tank unit to flow resistance, which is unfavorable to an energetically meaningful operation of the overall Institution affects. Also, the additional fluid lines lead to increased installation space, which often leads to problems in applications in vehicle technology and in mechanical and apparatus engineering, where often due to predetermined boundary conditions, little installation space is given.

Ausgehend von diesem Stand der Technik stellt sich daher die Erfindung die Aufgabe, unter Beibehalten der Vorteile der bekannten Lösungen diese dahingehend weiter zu verbessern, dass die in Rede stehenden Baueinheiten kompakt aufbauen, an bestehenden Tankeinheiten nachrüstbar und austauschbar sind, einen energetisch günstigen Betrieb sowie eine kostengünstige Realisierung ermöglichen.
Eine dahingehende Aufgabe löst eine Baueinheit mit den Merkmalen des Patentanspruches 1 in seiner Gesamtheit.Based on this prior art, therefore, the invention provides the task, while maintaining the advantages of the known solutions to further improve them to the effect that the units in question compact, can be retrofitted and replaced on existing tank units, an energetically favorable operation and a allow cost-effective implementation.
A related object solves a structural unit with the features of claim 1 in its entirety.

Gemäß dem kennzeichnenden Teil des Patentanspruches 1 sind drei Einheiten im rechten Winkel zueinander verlaufend an das Anschlussmodul anschließbar und bilden dergestalt eine Art T-Modul oder spannen ein fiktives kartesisches Koordinatensystem auf.According to the characterizing part of claim 1, three units are connected at right angles to each other extending to the connection module and form such a kind of T-module or span a fictitious Cartesian coordinate system.

Vorzugsweise besteht dabei das Anschlußmodul aus einem winkelförmigen Gehäuse mit zwei in einem rechten Winkel zueinander verlaufenden Anschlußarmen und weist ferner mindestens ein zusätzlich angeordnetes Flanschteil auf. Auf diese Art und Weise lassen sich in der Art eines T-Moduls oder in der Art eines kartesischen Koordinatensystems die einzelnen Einheiten der Baueinheit zueinander anordnen, was wiederum die freien Fluidwege innerhalb des Anschlußmoduls verkürzen und des weiteren an der Tankeinheit auch Einbauraum sparen hilft. Aufgrund der Ausgestaltung des Anschlußmodufs mit Anschlußarmen und Flanschteil lassen sich darüber hinaus in Sonderfällen noch weitere Anschlußmöglichkeiten für weitere Komponenten schaffen, beispielsweise in Form eines zweiten Filterelementes od. dgl..Preferably, the connection module consists of an angular housing with two at a right angle extending connecting arms and further comprises at least one additionally arranged flange. In this way, the individual units of the assembly can be arranged in the manner of a T-module or in the manner of a Cartesian coordinate system, which in turn reduces the free fluid paths within the connection module and also helps to save installation space on the tank unit. Due to the design of the Anschlußmodufs with connecting arms and flange part can also be in special cases provide even more connection options for other components, for example in the form of a second filter element od. Like ..

Die Baueinheit wird vorzugsweise an einer Seitenwand der Tankeinheit angeordnet. Durch die Entnahme über die Ansaugöffnung im Inneren der Tankeinheit sind die freien Fluidwege gegenüber bekannten Lösungen deutlich reduziert, was dem energetisch günstigen Betrieb der Gesamt-Baueinheit zugute kommt. Des weiteren baut die erfindungsgemäße Lösung kompakt auf und kann ohne weiteres gegen eine neue, beispielsweise eine solche Baueinheit mit größerem Leistungsvermögen, ausgetauscht werden, sofern dies notwendig werden sollte. Einem energetisch günstigen Betrieb der Gesamt-Baueinheit kommt auch zugute, dass die Kühleinheit in das Innere des zu kühlenden Mediums der Tankeinheit mündet, so dass unmittelbar über die Kühleinheit abgekühltes Medium an die Tankeinheit weiterleitbar ist. Dergestalt kommt es auch im Inneren der Tankeinheit zu einer homogenen Temperatursituation, was eine definierte Fluidentnahme über die Pumpeneinheit ermöglicht.The assembly is preferably arranged on a side wall of the tank unit. By removing the suction through the inside of the tank unit, the free fluid paths compared to known solutions are significantly reduced, which benefits the energetically favorable operation of the overall unit. Furthermore, the solution according to the invention builds compact and can be easily replaced with a new, for example, such a unit with greater capacity, if this should be necessary. An energetically favorable operation of the overall structural unit also benefits that the cooling unit opens into the interior of the medium to be cooled of the tank unit, so that medium cooled directly via the cooling unit can be forwarded to the tank unit is. In this way, it also comes in the interior of the tank unit to a homogeneous temperature situation, which allows a defined fluid removal via the pump unit.

Weitere vorteilhafte Ausgestaltungen der erfindungsgemäßen Baueinheit sind Gegenstand der sonstigen Unteransprüche.Further advantageous embodiments of the assembly according to the invention are the subject of the other dependent claims.

Das Gehäuse 26 des Anschlußmoduls 16 ist winkelförmig ausgebildet und weist zwei in einem rechten Winkel zueinander verlaufende Anschlußarme 28,30 auf, wobei an den Arm 28 die Filtereinheit 10 angeschlossen ist und der weitere zweite Anschlußarm 30 bildet eine Anschlußmöglichkeit für die Kühleinheit 14 aus. Ferner weist das Anschlußmodul 16 zur Pumpeneinheit 12 hin gewandt einen Pumpenflansch 32 auf und der Kühleinheit 14 zugewandt ist zwischen Tankeinheit 18 und Anschlußarm 30 ein Tankflansch 34 vorhanden. Mittels des Tankflansches 34 läßt sich die genannte Baueinheit mit der Tankeinheit lösbar verbinden. Ferner weist die Pumpeneinheit 12 auf ihrer dem Pumpenflansch 32 abgewandten Seite einen Antriebsmotor 36 für die Pumpeneinheit 12, vorzugsweise in Form eines Elektromotors auf. Wie in der Fig.1 dargestellt, kann der Antriebsmotor 36 über ein Fußelement 38, ebenso wie der Tankflansch 34, mit der Oberseite der Tankeinheit 18 verbunden sein. Des weiteren weist das Anschlußmodul 16 auf seiner der Kühleinheit 14 gegenüberliegenden Seite Anschlußstellen 40 für ein Kühlmedium auf. Um eine Anzeigemöglichkeit für den Verschmutzungsgrad des Filterelementes der Filtereinheit 10 zu haben, ist darüber hinaus auf der in Fig.1 gesehen oberen Seite des Anschlußmoduls 16 eine Verschmutzungsanzeige 42 vorhanden.The housing 26 of the connection module 16 is formed angularly and has two at a right angle extending connecting arms 28,30, wherein the arm 28, the filter unit 10 is connected and the further second connecting arm 30 forms a connection possibility for the cooling unit 14. Furthermore, the connection module 16 facing the pump unit 12 towards a pump flange 32 and the cooling unit 14 faces between the tank unit 18 and connecting arm 30, a tank flange 34 is present. By means of the tank flange 34, said assembly can be detachably connected to the tank unit. Furthermore, the pump unit 12 has on its side facing away from the pump flange 32 a drive motor 36 for the pump unit 12, preferably in the form of an electric motor. Like in the Fig.1 illustrated, the drive motor 36 via a foot member 38, as well as the tank flange 34, be connected to the top of the tank unit 18. Furthermore, the connection module 16 on its side opposite the cooling unit 14 side connecting points 40 for a cooling medium. In order to have an indication of the degree of contamination of the filter element of the filter unit 10, moreover, on the in Fig.1 seen top side of the connection module 16 a clogging indicator 42 is present.

Mit der erfindungsgemäßen Baueinheit nach der Fig.1 ist es möglich, in der Tankeinheit 18 bevorratetes Fluidmedium über die getrennt zu der Kühleinheit 14 geführte Ansaugöffnung 20 mittels der Pumpeneinheit 12 zu entnehmen, das dahingehend entnommene Medium anschließend über die Filtereinheit 10 zu filtrieren und das derart filtrierte Medium über die Kühleinheit 14 in die Tankeinheit 18 zurückzuführen, wobei als Kühleinheit vorzugsweise ein sog. Rohrbündelkühler eingesetzt wird. Der Aufbau dahingehender Kühler ist üblich, so dass an dieser Stelle hierauf nicht mehr näher eingegangen wird. Die Abgabe des gekühlten Mediums erfolgt über eine Abgabeöffnung 44 an der Unterseite des Rohrbündelkühlers in Form der zylindrischen Kühleinheit 14. Die jeweilige Einheit 10,12,14 ist bis auf die Tankeinheit 18 in der Art von zylindrischen Anschlußteilen für das Anschlußmodul 16 ausgeführt. Soll die Baueinheit von der Tankeinheit 18 entfernt werden, ist dies nach Lösen einer Schraubverbindung am Tankflansch 34 ohne weiteres möglich, wobei dann noch das Fußelement 38 des Antriebsmotors 36 gleichfalls zu lösen wäre. Es besteht aber auch die Möglichkeit, die Baueinheit an der Tankeinheit 18 zu belassen und beispielsweise zu Wartungszwecken ein verschmutztes Filterelement der Filtereinheit 10 zu wechseln, indem man das Gehäuse und/oder Teile des Gehäuses, wie beispielsweise einen Deckel, der Filtereinheit 10 entsprechend vom Anschlußmodul 16 abkoppelt bzw. entfernt.With the assembly according to the invention according to the Fig.1 it is possible to remove fluid medium stored in the tank unit 18 via the suction opening 20 guided separately to the cooling unit 14 by means of the pump unit 12, then to filter the medium removed therefrom via the filter unit 10 and the medium thus filtered via the cooling unit 14 into the tank unit 18, wherein as a cooling unit preferably a so-called tube bundle cooler is used. The structure of this cooler is common, so that will not be discussed here at this point. The delivery of the cooled medium via a discharge opening 44 at the bottom of the tube bundle cooler in the form of the cylindrical cooling unit 14. The respective unit 10,12,14 is carried out except for the tank unit 18 in the manner of cylindrical connecting parts for the connection module 16. If the assembly to be removed from the tank unit 18, this is easily possible after loosening a screw on the tank flange 34, in which case the foot element 38 of the drive motor 36 would also be solved also. But it is also possible to leave the assembly to the tank unit 18 and, for example, to replace a dirty filter element of the filter unit 10 by the housing and / or parts of the housing, such as a cover, the filter unit 10 according to the connection module 16 decouples or removes.

Um die Fluidführung zwischen den Einheiten 10,12,14 und innerhalb des Anschlußmoduls 16 zu verdeutlichen, ist das in Fig.2 dargestellte Anschlußmodul 16 in den nachfolgenden Figuren teilweise im Schnitt in verschiedenen Ansichten dargestellt. Das Anschlußmodul 16 nach der Fig.2 zeigt wiederum das Gehäuse 26 mit den beiden Anschlußarmen 28,30. Dem Betrachter der Fig.2 zugewandt ist an einer seitlichen Wand des Anschlußmoduls 16 der Pumpenflansch 32 angeordnet und als unterer Abschluß des Armes 30 schließt sich der Tankflansch 34 an das Anschlußmodul 16 an. Der Pumpenflansch 32 weist zwei Fluiddurchtrittsöffnungen auf, wobei sich in Blickrichtung auf die Fig.2 gesehen unten liegend der Sauganschluß 46 befindet und darüber liegend in einer vertikalen Ebene der Druckanschluß 48. Über die dahingehenden Anschlüsse 46,48 ist ein Fluidumlauf möglich mittels der Motorpumpeneinheit 36,12. In Blickrichtung auf die Fig.2 gesehen ist oben im Gehäuse 26 eine Anschlüßöffnung 50 für die Anschlußstellen 40 des Kühlmediums vorgesehen sowie eine Einschrauböffnung 52 für die Verschmutzungsanzeige 42. An der vorderen Stirnseite des Gehäuses 26 befindet sich die Aufnahmeöffnung 54 für das Gehäuse der Filtereinheit 10.To clarify the fluid management between the units 10,12,14 and within the connection module 16, which is in Fig.2 illustrated connection module 16 in the following figures partially in section in different views. The connection module 16 after the Fig.2 again shows the housing 26 with the two connecting arms 28,30. The viewer of the Fig.2 facing the pump flange 32 is disposed on a side wall of the connection module 16 and as the lower end of the arm 30, the tank flange 34 connects to the connection module 16 at. The pump flange 32 has two fluid passage openings, wherein in the direction of the Fig.2 Seen lying below the suction port 46 and lying in a vertical plane of the pressure port 48. About the pertinent ports 46,48 a fluid circulation is possible by means of the motor pump unit 36,12. In the direction of the Fig.2 seen in the housing 26 above a Anschlüßöffnung 50 is provided for the connection points 40 of the cooling medium and a screw-52 for the clogging indicator 42. At the front Front side of the housing 26 is the receiving opening 54 for the housing of the filter unit 10th

Wie insbesondere die Fig.3 zeigt, münden im Bereich der Aufnahmeöffnung 54 für die Filtereinheit 10 innerhalb des Gehäuses 26 der Druckanschluß 48 der Pumpeneinheit 12 in das Gehäuse 26, wobei sich dahingehend der Druckanschluß 48 in drei Verteileröffnungen 56 aufteilt (s.hierzu auch Fig.6). Auf diese Art und Weise kommt es zu einer verbesserten gleichmäßigen Verteilung des Fluidstroms in die zugehörige Filtereinheit 10. Über die dahingehenden Verteileröffnungen 56 gelangt verschmutztes Fluid zu dem Filterelement der Filtereinheit 10 und das abgereinigte Fluid gelangt über das Filterelement zurück in eine Sammelöffnung 58 (vgl. Fig.3), an die die Kühleinheit 14 fluidführend angeschlossen ist. Das über die Filtereinheit 10 derart abgereinigte Medium gelangt dann über die Sammelöffnung 58 in die Kühleinheit 14 und von dort aus gekühlt über die Abgabeöffnung 44 zurück in das Innere 22 der Tankeinheit 18. Wie sich des weiteren aus der Unteransicht auf den Tankflansch 34 nach der Fig.4 ergibt, ist dort eine Durchgangsöffnung 60 für die Aufnahme der Kühleinheit 14 vorhanden, wobei in Blickrichtung auf die Fig.4 gesehen deren unterer Aufnahmekreis um die Ansaugöffnung 20 erweitert ist, wobei insoweit an der Unterseite des Tankflansches 34 die Ansaugöffnung 20 in die Durchgangsöffnung 60 (vgl. Fig.6) einmündet. Wie des weiteren die Fig.6 zeigt, endet hingegen der Druckanschluß 48 an einer Innenwand des Gehäuses 26 des Anschlußmoduls 16 und über die Verteileröffnungen 56 wird dergestalt der Fluidstrom von dem Druckanschluß 48 kommend direkt in die Filtereinheit 10 für einen Abreinigungsvorgang des Mediums eingeleitet.How the particular Figure 3 shows, open in the region of the receiving opening 54 for the filter unit 10 within the housing 26 of the pressure port 48 of the pump unit 12 in the housing 26, to that extent the pressure port 48 into three distribution openings 56 divides (s.hierzu also Figure 6 ). In this way, there is an improved uniform distribution of the fluid flow in the associated filter unit 10. About the pertinent manifold openings 56 contaminated fluid reaches the filter element of the filter unit 10 and the cleaned fluid passes through the filter element back into a collection port 58 (see. Figure 3 ) to which the cooling unit 14 is fluidly connected. The medium thus cleaned off via the filter unit 10 then passes via the collection opening 58 into the cooling unit 14 and from there cooled via the discharge opening 44 back into the interior 22 of the tank unit 18. Further, as can be seen from the bottom view on the tank flange 34 Figure 4 results, there is a through hole 60 for receiving the cooling unit 14, wherein in the direction of the Figure 4 Seen whose lower receiving circuit is extended to the suction port 20, wherein in this respect on the underside of the tank flange 34, the suction port 20 into the passage opening 60 (see. Figure 6 ). How the other Figure 6 shows, however, the pressure port 48 terminates on an inner wall of the housing 26 of the connection module 16 and via the distribution openings 56 is thus introduced the fluid flow coming from the pressure port 48 directly into the filter unit 10 for a cleaning process of the medium.

Bei der erfindungsgemäßen Lösung befindet sich die Ansaugöffnung 20 in planparallelem Abschluß zu der Unterseite des Tankflansches 34. Ist die Baueinheit gemäß der Darstellung nach der Fig.1 auf die Tankeinheit 18 von der Oberseite her aufgesetzt, wäre darauf zu achten, dass die Tankeinheit 18 auch vollumfänglich mit Fluidmedium gefüllt ist, damit direkt an der Unterseite der Behälterwand der Tankeinheit 18 die Fluidentnahme über die Pumpeneinheit 12 mittels des Tankflansches 34 erfolgen kann. Es besteht dahingehend aber auch die Möglichkeit, bei einer nicht näher dargestellten Ausführungsform die in Rede stehende Ansaugöffnung 20 nach unten hin in Richtung des freien Endes der Kühleinheit 14 zu verlängern, was jedoch gegebenenfalls bedeutet, dass man ein zusätzliches Bauteil in Form eines Ansaugrohres od. dgl. einsetzen müßte. Vorzugsweise wird jedoch die Baueinheit seitlich an die Tankeinheit 18 angesetzt, wobei eine dahingehend typische Einbausituation realisiert ist, wenn man den Gegenstand nach der Fig.1 in Blickrichtung entgegen dem Uhrzeigersinn um 90° verschwenkt, so dass die Seitenbezeichnung 1/3 dann nach oben weist. Im dahingehenden Fall wäre dann eine Befüllung der Tankeinheit 18 nur bis zur Ansaugöffnung 20 des Tankflansches 34 notwendig. Unabhängig hiervon sind natürlich weitere Einbaumöglichkeiten realisierbar. Mit der erfindungsgemäßen Baueinheit ist es möglich, direkt ohne weitere Verrohrung in Form von Fluidleitungen eine Verbindung mit nahezu beliebigen Tankeinheiten 18 vorzusehen, um dergestalt Pump-, Filter- und Kühlleistungen am bevorrateten Medium vorzunehmen. Ferner besteht die Möglichkeit, im Sinne eines hydraulischen Kreises mittels der Motor-Pumpeneinheit das Medium aus der Tankeinheit 18 an eine andere Stelle, beispielsweise für einen Arbeitseinsatz einer Maschine (nicht dargestellt), zu verbringen, und das dann derart erwärmte und gegebenenfalls verschmutzte Fluid von der Baueinheit gekühlt und gereinigt für einen erneuten Umlauf an die Tankeinheit 18 abzugeben.In the inventive solution, the suction port 20 is in plane-parallel termination to the bottom of the tank flange 34. Is the Assembly according to the illustration of the Fig.1 be placed on the tank unit 18 from the top, it should be ensured that the tank unit 18 is also completely filled with fluid medium, so that directly on the underside of the container wall of the tank unit 18, the fluid removal via the pump unit 12 by means of the tank flange 34 can take place. There is, however, also the possibility to extend in a non-illustrated embodiment, the intake in question 20 down towards the free end of the cooling unit 14, but this may mean that you od an additional component in the form of an intake pipe. Like. would have to use. Preferably, however, the assembly is attached laterally to the tank unit 18, wherein a typical installation situation is realized in this case, if the object according to the Fig.1 pivoted in the direction counterclockwise by 90 °, so that the page name 1/3 then points upwards. In that case, a filling of the tank unit 18 would be necessary only up to the intake opening 20 of the tank flange 34. Regardless, of course, further installation options are feasible. With the structural unit according to the invention, it is possible to provide a connection with virtually any tank units 18 directly without further piping in the form of fluid lines in order to perform pumping, filtering and cooling services on the stored medium. It is also possible, in the sense of a hydraulic circuit by means of the motor-pump unit, the medium from the tank unit 18 to another location, for example, for a labor input of a machine (not shown) to spend, and then heated so and possibly contaminated fluid from the assembly cooled and cleaned for a new circulation to the tank unit 18 deliver.
