Description

Die Erfindung betrifft eine fluiddurchströmte Baugruppe, insbesondere eine modular aufgebaute Vorrichtung zur Druckluftaufbereitung, mit einer Verbindungseinrichtung für zwei Basiskörper der fluiddurchströmten Baugruppe, mit an den einander zugewandten Verbindungsflächen der zu verbindenden Basiskörper vorgesehenen Haltemitteln, und mit einer zwischen die zu verbindenden Basiskörper eingreifenden Kupplungseinheit, die zwei quer zur Verbindungsrichtung der beiden Basiskörper miteinander verspannbare und dabei unter Vermittlung von bezüglich der Verbindungsrichtung geneigt verlaufenden Schrägflächen eine im Sinne einer gegenseitigen Annäherung der Basiskörper wirkende Verbindungskraft auf die Haltemittel ausübende Kupplungskörper enthält.The invention relates to a fluid-flow assembly, in particular a modular device for Compressed air treatment, with a connection device for two basic bodies of the fluid-flow assembly, with the mutually facing connecting surfaces of the to be connected Base body provided holding means, and with a between engaging the base body to be connected Coupling unit, the two transverse to the connection direction of the two base bodies can be clamped together and under Switching inclined with respect to the connection direction extending inclined surfaces one in the sense of a mutual Approximation of the base body acting on the connecting force Contains coupling body exercising retaining means.

Eine derartige fluiddurchströmte Baugruppe ist beispielsweise in der US-A-5,383,689 beschrieben, in der ein Verbindungsglied zum fluiddichten Verbinden zweier modularer Druckluftkomponenten offenbart ist. Das Verbindungsglied umfaßt einen Verbindungsblock und einen mit diesem zusammenwirkenden Montageblock, die einander zugewandte Dichtflächen besitzen, die bei der Montage mit Hilfe von ineinandergreifenden, einen Keilsitz bildenden Keilelementen fluiddicht zusammengespannt werden.Such a fluid-flow assembly is, for example in US-A-5,383,689, in which a Connector for the fluid-tight connection of two modular Compressed air components is disclosed. The link comprises a connection block and one with this interacting mounting block facing each other Have sealing surfaces that can be used during assembly with the interlocking wedge elements forming a wedge seat can be clamped together in a fluid-tight manner.

Eine Verbindungseinrichtung für fluiddurchströmte Baugruppen ist beispielsweise auch in der WO 95/02149 im Zusammenhang mit einer Vorrichtung zur Druckluftaufbereitung beschrieben. Letztere enthält mehrere Komponenten, deren gehäuseartige Basiskörper unter Zwischenschaltung einer Kupplungseinheit fest und zugleich fluiddicht miteinander verbunden werden. Die Kupplungseinheit enthält einen zwischen die beiden Basiskörper einführbaren schieberartigen ersten Kupplungskörper, der mit einem von der entgegengesetzten Seite her angesetzten zweiten Kupplungskörper verspannt wird, so dass an den Kupplungskörpern vorgesehene geneigte Beaufschlagungsflächen mit entsprechend geneigten Schrägflächen der Basiskörper zusammenarbeiten und nach dem Keilprinzip dafür sorgen, dass die Basiskörper miteinander verspannt werden. Die Schrägflächen der Basiskörper sind an Haltemitteln vorgesehen, die von einstückigen randseitigen Fortsätzen der Basiskörper gebildet sind.A connection device for fluid-flow-through assemblies is also related, for example, in WO 95/02149 described with a device for compressed air treatment. The latter contains several components, the housing-like Base body with the interposition of a coupling unit be firmly and fluid-tightly connected at the same time. The clutch unit contains one between the two Basic body insertable slide-like first coupling body, the one with the opposite side attached second coupling body is clamped so that inclined loading surfaces provided on the coupling bodies with correspondingly inclined sloping surfaces Base body work together and on the wedge principle for it ensure that the base bodies are clamped together. The sloping surfaces of the base body are on holding means provided by one-piece edge-side extensions of the Base body are formed.

Bei einer aus der US 5,372,392 bekannten ähnlichen Verbindungseinrichtung werden nach dem Zusammensetzen zweier Basiskörper klammerartige Kupplungskörper von außen her angesetzt. Um eine druckdichte Verbindung zu schaffen; wird hier eine separate gelochte Zwischenplatte zwischen die zu verbindenden Basiskörper eingesetzt.In a similar connection device known from US 5,372,392 become after putting two together Base body clamp-like coupling body from the outside stated. To create a pressure tight connection; becomes here a separate perforated intermediate plate between the connecting base body used.

Im Gegensatz dazu beschreibt die DE 197 07 630 C1 eine verbindungseinrichtung, bei der die Basiskörper an ihren Verbindungsflächen unmittelbar aneinander anliegen, wobei miteinander verspannte Kupplungskörper im Bereich der Seitenflächen der Basiskörper angesetzt werden.In contrast, DE 197 07 630 C1 describes one connecting device in which the base body on their Connection surfaces lie directly against each other, whereby coupling body clamped together in the area of Side faces of the base body are attached.

Die Aufgabe der vorliegenden Erfindung besteht darin, eine fluiddurchströmte Baugruppe der eingangs genannten Art zu schaffen, die bei einfachem Aufbau eine leichte Handhabung und eine zuverlässige Verbindung zweier Basiskörper ermöglicht. The object of the present invention is a fluid-flow assembly of the type mentioned create that with a simple structure easy handling and a reliable connection between two base bodies allows.

Ausgehend von einer fluiddurchströmten Baugruppe der eingangs genannten Art wird diese Aufgabe dadurch gelöst, dass die an einem jeweiligen Basiskörper vorgesehenen Haltemittel jeweils mindestens einen zum jeweils anderen Basiskörper ragenden Haltebolzen aufweisen, der zwischen die beiden Kupplungskörper eingreift und gleichzeitig von Beaufschlagungsflächen beider Kupplungskörper umfangsseitig beaufschlagt wird.Starting from a fluid-flow assembly at the beginning mentioned type this task is solved in that the holding means provided in each case at least one protruding to the other base body Have retaining bolts between the two coupling bodies intervenes and at the same time from contact surfaces both coupling bodies are acted upon circumferentially.

Auf diese Weise können die die Basiskörper miteinander verspannenden Verbindungskräfte punktuell gezielt an den relevanten Stellen eingeleitet werden, um die Basiskörper bewußt in denjenigen Bereichen miteinander zu verspannen, die konstruktionstechnisch und funktionstechnisch am günstigsten sind. Es besteht beispielsweise die Möglichkeit, die Krafteinleitung der Verbindungskräfte so vorzunehmen, dass im Umfangsbereich miteinander kommunizierender Fluidkanäle der Basiskörper eine optimale Dichtpressung erzielt wird. Im Vergleich dazu erfolgt beim Stand der Technik die Krafteinleitung jeweils zwingend am Rand der Basiskörper, was nicht immer die gewünschte Flächenpressung gewährleisten kann. Bei alledem läßt sich die Verbindungseinrichtung sehr einfach herstellen und ist äußerst bedienungsfreundlich.In this way, the base body together selectively tensioning connecting forces to the Relevant bodies are initiated to the basic body consciously bracing each other in those areas that best in terms of construction and function are. For example, there is a possibility that Force transmission of the connecting forces so that in Circumferential area of fluid channels communicating with one another Base body an optimal sealing pressure is achieved. in the A comparison is made in the prior art Force transmission mandatory at the edge of the base body what do not always guarantee the desired surface pressure can. In all of this, the connector can be very easy to manufacture and extremely easy to use.

Vorteilhafte Weiterbildungen der Erfindung gehen aus den Unteransprüchen hervor.Advantageous developments of the invention can be seen in the Sub-claims emerge.

Es wäre prinzipiell möglich, zur Verbindung der Kupplungseinheit mit einem jeweiligen Basiskörper lediglich einen Haltebolzen vorzusehen. Aus Gründen der Symmetrie und optimalen Krafteinleitung wird man jedoch regelmäßig pro Basiskörper auf mehrere Haltebolzen zurückgreifen, wobei sich insbesondere jeweils zwei zueinander beabstandete Haltebolzen empfehlen, die wiederum gleichzeitig mit Beaufschlagungsflächen beider Kupplungskörper zusammenarbeiten können.In principle, it would be possible to connect the coupling unit with only one base body To provide retaining bolts. For reasons of symmetry and optimal Force application is however regularly pro Base body fall back on several retaining bolts, whereby in particular two spaced-apart retaining bolts recommend, which, in turn, at the same time with the application areas both coupling bodies can work together.

Soll durch die Verbindungseinrichtung gleichzeitig eine fluiddichte Verbindung von Fluidkanälen der beiden Basiskörper hergestellt werden, ist es von Vorteil, wenn die beiden Haltebolzen an der zugeordneten Verbindungsfläche auf einander diametral gegenüberliegenden Seiten der betreffenden Kanalmündung angeordnet sind.Should be at the same time by the connecting device fluid-tight connection of fluid channels of the two base bodies are produced, it is advantageous if the two Retaining bolts on each other on the assigned connecting surface diametrically opposite sides of the respective channel mouth are arranged.

Die beiden Haltebolzen befinden sich zweckmäßigerweise jeweils innerhalb des Umrisses der mit der Kupplungseinheit in Kontakt stehenden Verbindungsfläche des zugeordneten Basiskörpers, sind dabei jedoch insbesondere in Randnähe der betreffenden Verbindungsfläche plaziert, um einen großen Strömungsquerschnitt für zu verbindende Fluidkanäle zu ermöglichen.The two retaining bolts are each conveniently located within the outline of that with the clutch unit in Contacting connecting surface of the assigned base body, are particularly close to the relevant connection area placed to a large To allow flow cross-section for fluid channels to be connected.

Zugunsten einer gleichförmigen Einleitung der Verbindungskraft ist es ferner von Vorteil, wenn die Haltebolzen der zu verbindenden Basiskörper einander paarweise koaxial gegenüberliegen. Sind zum gegenseitigen Verspannen der beiden Kupplungskörper Schraubverbindungsmittel vorgesehen, die über an den beiden Kupplungskörpern angreifende Spannschrauben verfügen, ist die Anordnung zweckmäßigerweise so getroffen, dass jeweils eine der Spannschrauben den axialen Zwischenraum zweier einander paarweise zugeordneter Haltebolzen durchsetzt. Auf diese Weise werden die durch die Spannschrauben eingeleiteten Spannkräfte auf kürzestem Wege umgelenkt und in die Haltebolzen eingeleitet. In favor of a uniform introduction of the connecting force it is also advantageous if the retaining bolts to connecting base body coaxially opposite each other in pairs. Are for the mutual bracing of the two Coupling body provided screw fasteners that over clamping screws acting on the two coupling bodies the arrangement is expediently made such that one of the clamping screws each the axial space passes through two mutually assigned retaining bolts. In this way, the clamping screws initiated clamping forces deflected by the shortest route and in the retaining bolts initiated.

Bei verspannten Kupplungskörpern kooperieren die an diesen vorgesehenen Beaufschlagungsflächen mit an den Haltebolzen vorgesehenen Gegenbeaufschlagungsflächen. Obgleich jeweils nur eine dieser Flächenarten einen geneigten Verlauf haben kann, ist es doch von Vorteil, wenn in beiden Fällen eine Ausgestaltung als Schrägflächen erfolgt, deren Neigungswinkel bezüglich der Verbindungseinrichtung zweckmäßigerweise identisch ist, so dass sie parallel zueinander verlaufen. Die Schrägflächen können je nach Ausführungsform geradlinig oder auch gekrümmt konturiert sein.If the coupling bodies are tensioned, they cooperate on them provided loading surfaces with on the retaining bolts provided counter-application areas. Although each only one of these surface types has an inclined course can, it is an advantage if one in both cases Designed as inclined surfaces, their angle of inclination expediently identical with regard to the connecting device is so that they are parallel to each other. The Depending on the design, inclined surfaces can be straight or also be contoured curved.

Die Haltebolzen könnten zwar einstückiger Bestandteil des zugeordneten Basiskörpers sein, doch empfiehlt sich aus fertigungstechnischen Gründen eine separate Ausgestaltung mit anschließender fester Verankerung am zugeordneten Basiskörper. Zur Verankerung kann dabei insbesondere eine Gewindeverbindung vorgesehen sein, wobei die Haltebolzen über einen Gewindeschaft verfügen können, mit dem sie in den zugeordneten Basiskörper fest eingeschraubt werden.The retaining bolts could indeed be an integral part of the assigned Be basic body, but is recommended for manufacturing Establish a separate configuration with subsequent fixed anchoring to the assigned base body. A threaded connection can in particular be used for anchoring be provided, the retaining bolts via a threaded shaft with which they can be assigned to the assigned base body be screwed tight.

Es ist ferner von Vorteil, wenn die Gegenbeaufschlagungsflächen der Haltebolzen jeweils an einem umlaufenden Radialvorsprung des betreffenden Haltebolzens vorgesehen sind, der von einem Kopf des Haltebolzens gebildet sein kann. Die Gegenbeaufschlagungsfläche hat dabei zweckmäßigerweise eine kegelige, sich in Richtung zur zugeordneten Verbindungsfläche hin verjüngende Gestalt. It is also advantageous if the counteracting surfaces the retaining bolt each on a circumferential radial projection of the relevant retaining bolt are provided by a head of the retaining bolt can be formed. The counteracting surface expediently has a conical, towards the assigned connection surface rejuvenating shape.

Bei hergestellter Verbindung sind die Kupplungskörper zweckmäßigerweise sowohl untereinander als auch jeweils sowohl mit den Haltebolzen als auch mit den Verbindungsflächen der Basiskörper verspannt. Hierzu kann jeder Haltebolzen eine der Verbindungsfläche des ihn tragenden Basiskörpers zugewandte und mit den zugeordneten Beaufschlagungsflächen der Kupplungskörper kooperierende Gegenbeaufschlagungsfläche aufweisen, wobei die Kupplungskörper zwischen eine jeweilige Gegenbeaufschlagungsfläche und die dieser zugewandte Verbindungsfläche eintauchen und sowohl die Gegenbeaufschlagungsfläche als auch die Verbindungsfläche beaufschlagen. Es ist zweckmäßigerweise vorgesehen, dass die Kupplungskörper im miteinander verspannten Zustand unter Bildung eines Festanschlages aneinander anliegen.When the connection is made, the coupling bodies are expedient with each other as well as with each the retaining bolt as well as with the connecting surfaces of the base body braced. For this purpose, each retaining bolt can be one of the Connection surface facing the base body carrying it and with the associated loading surfaces of the coupling body have cooperating counteracting surface, wherein the coupling body between a respective counter-loading surface and the connection surface facing this immerse and both the counteracting surface as well as the connecting surface. It is convenient provided that the coupling body in one with the other tense condition with formation of a fixed stop abut each other.

Soll durch die Kupplungseinheit hindurch eine fluidische Verbindung zwischen Fluidkanälen der beiden Basiskörper erfolgen, ist es von Vorteil, wenn ein entsprechender Durchgangskanal der Kupplungseinheit komplett in lediglich einem der beiden Kupplungskörper ausgebildet ist, so dass zwischen den beiden Kupplungskörpern keine Abdichtungsmaßnahmen erforder-. lich sind. Um gleichwohl kompakte Abmessungen der Kupplungseinheit zu ermöglichen, kann der Durchgangskanal an der dem anderen Kupplungskörper zugewandten Seite von einer sich auswölbenden Wand begrenzt sein, die in eine komplementäre Vertiefung des anderen Kupplungskörpers eintaucht.Should be a fluid connection through the coupling unit between fluid channels of the two base bodies, it is advantageous if a corresponding through channel the coupling unit completely in only one of the is formed so that between the coupling body no sealing measures required for both coupling bodies. are. Nevertheless compact dimensions of the coupling unit to enable the through channel on the other coupling body facing side from a bulging Wall to be bounded in a complementary recess immersed in the other coupling body.

Die Figur 1 zeigt exemplarisch eine zur Druckluftaufbereitung bzw. -konditionierung dienende Vorrichtung 1, die im einsatzbereiten Zustand in eine nicht näher dargestellte Druckluftleitung zwischengeschaltet ist. Die Vorrichtung 1 könnte auch als Druckluft-Wartungseinrichtung bezeichnet werden. Sie ist als modular aufgebaute, im Betrieb fluiddurchströmte Baugruppe ausgeführt, die beim Ausführungsbeispiel zwei nur schematisch abgebildete Funktionseinheiten 2a, 2b enthält, bei denen es sich beispielsweise um eine Druckregeleinheit, eine Filtereinheit und/oder eine Ölereinheit handeln kann.Figure 1 shows an example of a compressed air treatment or conditioning device 1, which is ready for use Condition in a compressed air line, not shown is interposed. The device 1 could also be called a compressed air maintenance device. she is as a modular assembly with fluid flow during operation executed, the two embodiment only schematically functional units 2a, 2b shown, in which it is, for example, a pressure control unit, a Filter unit and / or an oiler unit can act.

Die einzelnen Funktionseinheiten verfügen jeweils über einen beim Ausführungsbeispiel quader- oder würfelähnlichen Körper, der in der Regel gehäuseähnlich aufgebaut ist und vorliegend als Basiskörper 3a, 3b bezeichnet sei.The individual functional units each have one in the embodiment of cuboid or cube-like bodies, which is usually constructed like a housing and is available may be referred to as base body 3a, 3b.

Jeder der Basiskörper 3a, 3b enthält jeweils mindestens einen internen Fluidkanal 4a, 4b, der in Figur 3 strichpunktiert angedeutet ist und an einander entgegengesetzten Stirnflächen des betreffenden Basiskörpers 3a, 3b ausmündet. Die Basiskörper 3a, 3b können in beliebiger Anzahl entlang einer durch eine strichpunktierte Linie angedeuteten Verbindungsrichtung 5 aufgereiht werden, wobei sich unmittelbar aufeinanderfolgende Basiskörper unter Vermittlung der erfindungsgemäßen Verbindungseinrichtung 6 lösbar fest miteinander verbinden lassen. Dabei werden gleichzeitig auch die Fluidkanäle 4a, 4b benachbarter Basiskörper 3a, 3b miteinander verbunden, so dass sich ein gemeinsamer, die gesamte Vorrichtung 1 durchziehender Strömungskanal ergibt, der mit den anschließbaren Fluidleitungen kommuniziert. Innerhalb einer jeweiligen Funktionseinheit 2a, 2b verfügt der den entsprechenden Abschnitt des Strömungskanals bildende Fluidkanal 4a, 4b über einen funktionsspezifischen Verlauf und kann beispielsweise bewirken, dass das fluidische Druckmedium durch eine Filtereinrichtung oder eine Druckregeleinrichtung hindurchgeleitet wird. Each of the base bodies 3a, 3b contains at least one internal fluid channel 4a, 4b, which is dash-dotted in Figure 3 is indicated and on opposite end faces of the relevant base body 3a, 3b opens out. The base body 3a, 3b can be in any number along one a dash-dotted line indicated connection direction 5 can be lined up, with consecutive Base body with the mediation of the invention Connect the connecting device 6 releasably to one another to let. The fluid channels 4a, 4b adjacent base body 3a, 3b connected to each other, see above that a common, which runs through the entire device 1 Flow channel results that with the connectable Fluid lines communicated. Within a respective functional unit 2a, 2b has the corresponding section the fluid channel 4a, 4b forming the flow channel via a function-specific course and can, for example, that the fluid pressure medium through a filter device or passed a pressure control device becomes.

Die Verbindungseinrichtung 6 enthält eine Kupplungseinheit 7, die zwischen die zu verbindenden Basiskörper 3a, 3b eingreift, indem sie zwischen die Basiskörper 3a, 3b zwischengefügt wird. Im fest verbundenen Zustand liegen die Basiskörper 3a, 3b mit einander zugewandten Verbindungsflächen 9a, 9b an einer zugewandten Kupplungsfläche 12a, 12b der zwischengefügten Kupplungseinheit 7 an. Die Verbindungsflächen 9a, 9b sind dabei an denjenigen Seitenflächen der Basiskörper 3a, 3b vorgesehen, an denen sich eine Kanalmündung 8a, 8b des zugeordneten Fluidkanals 4a, 4b befindet. Die Kupplungsflächen 12a, 12b befinden sich auf einander entgegengesetzten Seiten der Kupplungseinheit 7.The connecting device 6 contains a coupling unit 7, which engages between the base bodies 3a, 3b to be connected, by interposing them between the base bodies 3a, 3b becomes. The base body lies in the firmly connected state 3a, 3b with mutually facing connection surfaces 9a, 9b a facing coupling surface 12a, 12b of the interposed Coupling unit 7 on. The connecting surfaces 9a, 9b are provided on those side surfaces of the base body 3a, 3b, at which a channel mouth 8a, 8b of the assigned Fluid channel 4a, 4b is located. The coupling surfaces 12a, 12b are on opposite sides of the Coupling unit 7.

Unter Vermittlung der Verbindungseinrichtung 6 können die Basiskörper 3a, 3b unter Zwischenschaltung der Kupplungseinheit 7 zu einer gemeinsam handhabbaren Baueinheit in lösbarer Weise fest miteinander verspannt werden.By means of the connection device 6, the base body can 3a, 3b with the interposition of the coupling unit 7 to a jointly manageable unit in a detachable manner be firmly clamped together.

Die Kupplungseinheit 7 verfügt über einen Durchgangskanal 13, der die Kupplungseinheit 7 zweckmäßigerweise in der Verbindungsrichtung 5 durchsetzt und zu beiden Kupplungsflächen 12a, 12b aufmündet. Seine Ausmündungen 14 fluchten dabei mit der jeweils zugeordneten Kanalmündung 8a, 8b, wobei im Fügebereich zwischen der Kupplungseinheit 7 und einem jeweiligen Basiskörper 3a, 3b eine zu den vorerwähnten Mündungen konzentrisch angeordnete ringförmige Dichtung 15 zwischengefügt ist, die einen nach außen hin abgedichteten Übergang zwischen den Fluidkanälen 4a, 4b und den Durchgangskanal 13 gewährleisten. Die ringförmige Dichtung 15 besteht in der Regel aus elastisch nachgiebigem Material und wird zwischen einerseits den Verbindungsflächen 9a, 9b und andererseits den Kupplungsflächen 12a, 12b axial verspannt.
Die Verbindungseinrichtung 6 enthält zusätzlich zu der Kupplungseinheit 7 an den zu verbindenden Basiskörpern 3a, 3b angeordnete Haltemittel, die in Gestalt einzelner Haltebolzen 16 ausgeführt sind, welche sich an den Verbindungsflächen 9a, 9b befinden, wobei sie vorzugsweise innerhalb des beim Ausführungsbeispiel rechteckförmigen Umrisses der jeweils zugeordneten Verbindungsfläche 9a, 9b plaziert sind. Bezogen auf zwei miteinander zu verbindende Basiskörper 3a, 3b ist dabei vorgesehen, dass jeder Basiskörper 3a, 3b an der dem anderen Basiskörper 3b, 3a zugewandten Verbindungsfläche 9a, 9b mindestens einen Haltebolzen 16 aufweist, der nach Art eines Vorsprunges über die zugeordnete Verbindungsfläche 9a, 9b vorsteht und ausgehend von dieser in Richtung zur gegenüberliegenden Verbindungsfläche des anderen Basiskörpers wegragt.The coupling unit 7 has a through channel 13, which expediently passes through the coupling unit 7 in the connecting direction 5 and opens out to both coupling surfaces 12a, 12b. Its mouths 14 are aligned with the respectively assigned channel mouth 8a, 8b, an annular seal 15, which is arranged concentrically with the aforementioned mouths and which seals an externally sealed transition between the two, is inserted in the joining area between the coupling unit 7 and a respective base body 3a, 3b Ensure fluid channels 4a, 4b and the through channel 13. The ring-shaped seal 15 generally consists of elastically flexible material and is axially clamped between the connecting surfaces 9a, 9b on the one hand and the coupling surfaces 12a, 12b on the other hand.
In addition to the coupling unit 7, the connecting device 6 contains holding means which are arranged on the base bodies 3a, 3b to be connected and are designed in the form of individual holding bolts 16 which are located on the connecting surfaces 9a, 9b, preferably within the rectangular outline of the respective embodiment in the exemplary embodiment associated connecting surface 9a, 9b are placed. In relation to two base bodies 3a, 3b to be connected to one another, it is provided that each base body 3a, 3b has at least one retaining bolt 16 on the connection surface 9a, 9b facing the other base body 3b, 3a, which, in the manner of a projection, over the associated connection surface 9a, 9b protrudes and protrudes from it in the direction of the opposite connecting surface of the other base body.

Die Haltebolzen 16 kooperieren mit der Kupplungseinheit 7, die über zwei quer zu der Verbindungsrichtung 5 miteinander verspannbare erste und zweite Kupplungskörper 17, 18 verfügt. Die Verspannrichtung 19 ist in der Zeichnung durch eine strichpunktierte Linie verdeutlicht. Diese erstreckt sich parallel zur Ebene der untereinander ebenfalls parallelen Kupplungsflächen 12a, 12b und dabei rechtwinkelig zu der Verbindungsrichtung 5.The retaining bolts 16 cooperate with the coupling unit 7, the two across to the direction of connection 5 with each other braced first and second coupling body 17, 18 has. The bracing direction 19 is in the drawing by a dash-dotted line clarifies. This extends in parallel to the level of the coupling surfaces, which are also parallel to one another 12a, 12b and at right angles to the connection direction 5th

Die Haltebolzen 16 greifen zwischen die beiden Kupplungskörper 17, 18 ein, wobei sie umfangsseitig jeweils über eine Gegenbeaufschlagungsfläche 24 verfügen, die gleichzeitig von ersten und zweiten Beaufschlagungsflächen 22, 23 der beiden Kupplungskörper 17, 18 beaufschlagbar ist. Entweder die beiden Beaufschlagungsflächen 22, 23 oder die Gegenbeaufschlagungsfläche 24, vorzugsweise aber sowohl die beiden Beaufschlagungsflächen 22, 23 als auch die Gegenbeaufschlagungsfläche 24 - letzteres trifft für das Ausführungsbeispiel zu - sind als Schrägflächen ausgebildet, die bezüglich der Verbindungsrichtung 5 einen geneigten verlauf haben, wobei der Neigungswinkel in der Zeichnung mit dem Buchstaben "w" bezeichnet ist. Dabei ist der Neigungswinkel der Beaufschlagungsflächen 22, 23 und der Gegenbeaufschlagungsfläche 24 vorzugsweise identisch.The retaining bolts 16 engage between the two coupling bodies 17, 18 a, wherein they are circumferentially in each case via a counter-loading surface 24, which at the same time by first and second application surfaces 22, 23 of the two Coupling body 17, 18 can be acted upon. Either the two Acting surfaces 22, 23 or the counteracting surface 24, but preferably both the two application surfaces 22, 23 as well as the counteracting surface 24 - the latter applies to the exemplary embodiment - are designed as inclined surfaces with respect to the connection direction 5 have an inclined course, the angle of inclination designated in the drawing with the letter "w" is. The angle of inclination of the surfaces to be applied 22, 23 and the counteracting surface 24 preferably identical.

Wie aus Figuren 4 und 5 hervorgeht, ist die Gegenbeaufschlagungsfläche 24 der Verbindungsfläche 9a, 9b des den betreffenden Haltebolzen 16 tragenden Basiskörpers 3a, 3b mit Abstand vorgelagert, gleichzeitig jedoch der vorerwähnten Verbindungsfläche zugewandt. Die Beaufschlagungsflächen 22, 23 hingegen sind so an den beiden Kupplungskörpern 17, 18 angeordnet, dass sie von derjenigen Verbindungsfläche 9a, 9b verweisen, die denjenigen Haltebolzen 16 aufweist, mit dem sie individuell kooperieren. Dabei verlaufen sowohl die Beaufschlagungsflächen 22, 23 als auch die Gegenbeaufschlagungsfläche 24 mit zunehmendem Abstand von der zugeordneten Verbindungsfläche 9a, 9b schräg quer zur Verbindungsrichtung 5 nach außen.As can be seen from FIGS. 4 and 5, the counteracting surface is 24 of the connecting surface 9a, 9b of the one in question Holding bolt 16 supporting base body 3a, 3b at a distance upstream, but at the same time the aforementioned connection surface facing. The application surfaces 22, 23 on the other hand, are arranged on the two coupling bodies 17, 18, that they point from that connecting surface 9a, 9b, which has the retaining bolt 16 with which it cooperate individually. Both the application areas run 22, 23 as well as the counteracting surface 24 with increasing distance from the associated connecting surface 9a, 9b obliquely transversely to the connection direction 5 outward.

Um die feste Verbindung zwischen den Basiskörpern 3a, 3b herzustellen, werden die beiden zweckmäßigerweise als eigenständige Bauteile ausgeführten Kupplungskörper 17, 18 von einander entgegengesetzten Seiten her in der Verspannungsrichtung 19 zwischen die Basiskörper 3a, 3b eingeführt und an die Haltebolzen 16 angesetzt. Diese Phase ist in Figuren 2 und 4 illustriert. Anschließend werden die beiden Kupplungskörper 17, 18 durch Spannmittel 25 in der Verspannungsrichtung 19 gegeneinander gezogen und mit einer Spannkraft Fs fest miteinander verspannt, wobei die ersten und zweiten Beaufschlagungsflächen 22, 23 an der Gegenbeaufschlagungsfläche 24 der Haltebolzen 16 zur Anlage gelangen und diese beaufschlagen. Bei diesem Verspannungsvorgang werden durch die aneinander abgleitenden Beaufschlagungsflächen und Gegenbeaufschlagungsflächen gleichzeitig die einander zugewandten Kupplungsflächen 12a, 12b und Verbindungsflächen 9a, 9b einander angenähert und gegeneinander vorgespannt. Insgesamt führt dieses Keilprinzip dazu, dass aus der in der Verspannungsrichtung 19 eingeleiteten Spannkraft Fs eine in der Verbindungsrichtung 5 wirksame Verbindungskraft Fv abgeleitet wird, mit der die fest mit den Haltebolzen 16 verbundenen Basiskörper 3a, 3b zueinander gezogen und unter Zwischenschaltung der Kupplungseinheit 7 fest miteinander verspannt werden.In order to establish the fixed connection between the base bodies 3a, 3b, the two coupling bodies 17, 18, which are expediently designed as independent components, are inserted from opposite sides in the bracing direction 19 between the base bodies 3a, 3b and attached to the retaining bolts 16. This phase is illustrated in Figures 2 and 4. Subsequently, the two coupling bodies 17, 18 are pulled against one another in the tensioning direction 19 by tensioning means 25 and firmly tensioned to one another with a tensioning force F s , the first and second action surfaces 22, 23 coming to bear against the action surface 24 of the retaining bolts 16 and acting on them. In this tensioning process, the coupling surfaces 12a, 12b and connecting surfaces 9a, 9b, which are facing one another, are simultaneously brought closer to one another and prestressed against one another by the mutually sliding application surfaces and counter-application surfaces. Overall, this wedge principle leads to the fact that from the tension force F s introduced in the tensioning direction 19, a connection force F v effective in the connection direction 5 is derived, with which the base bodies 3a, 3b firmly connected to the retaining bolts 16 are pulled towards one another and with the coupling unit 7 interposed be firmly clamped together.

Beim Ausführungsbeispiel besitzen die Gegenbeaufschlagungsflächen 24 eine kegelige Gestalt. Dementsprechend können die ersten und zweiten Beaufschlagungsflächen 22, 23 jeweils von einem Umfangsabschnitt einer einen entsprechenden Kegelwinkel aufweisenden Kegelfläche gebildet sein. Prinzipiell wäre hier aber auch eine ebene Schrägfläche denkbar.In the embodiment, the counteracting surfaces have 24 a conical shape. Accordingly, the first and second application surfaces 22, 23 each of a peripheral portion of a corresponding cone angle having a conical surface. In principle would be here but also a flat inclined surface is conceivable.

Insgesamt ist darauf hinzuweisen, dass die Schrägflächen nicht notwendigerweise einen linear Verlauf besitzen müssen, es kann sich bei ihnen auch um gewölbte bzw. gekrümmte Flächen handeln.
Die Haltebolzen 16 könnten zwar prinzipiell als einstückige Bestandteile der Basiskörper 3a, 3b ausgeführt werden, doch empfiehlt sich die beim Ausführungsbeispiel realisierte Bauform als separate Bauelemente, die am zugehörigen Basiskörper 3a, 3b durch geeignete Mittel befestigt bzw. verankert sind. Es ist insbesondere eine lösbare Befestigung vorgesehen, wobei jeder Basiskörper 3a, 3b an beiden einander entgegengesetzten Verbindungsflächen über geeignete Befestigungsmittel 26 verfügt, die eine bedarfgemäße Verankerung eines Haltebolzens 16 ermöglichen. Auf diese Weise ist es möglich, die Basiskörper 3a, 3b nach Bedarf nur an denjenigen Seitenflächen mit Haltebolzen 16 auszustatten, an denen eine Verbindung mit einem anderen Basiskörper stattfinden soll.Overall, it should be pointed out that the inclined surfaces do not necessarily have to have a linear course, they can also be curved or curved surfaces.
The retaining bolts 16 could in principle be designed as one-piece components of the base body 3a, 3b, but the design realized in the exemplary embodiment is recommended as separate components which are fastened or anchored to the associated base body 3a, 3b by suitable means. In particular, a releasable fastening is provided, with each base body 3a, 3b having suitable fastening means 26 on both mutually opposite connecting surfaces, which enable a retaining bolt 16 to be anchored as required. In this way, it is possible to equip the base bodies 3a, 3b with retaining bolts 16 only on those side surfaces at which a connection to another base body is to take place.

Beim Ausführungsbeispiel sind die Haltebolzen 16 mit dem zugeordneten Basiskörper 3a, 3b verschraubt. Hierzu können die Befestigungsmittel 26 wie abgebildet als im Bereich der Verbindungsflächen 9a, 9b in die Basiskörper 3a, 3b eingebrachte Gewindebohrungen ausgeführt sein, in die die Haltebolzen mit einem an ihnen vorgesehenen Gewindeschaft 27 einschraubbar sind. Die Haltebolzen 16 sind hier also von einer Art Sonderschrauben gebildet und verfügen zweckmäßigerweise über eine besonders geformte Werkzeugangriffspartie 28 - beispielsweise einen Mehrkantabschnitt -, der das Ansetzen eines Schraubwerkzeuges ermöglicht.In the exemplary embodiment, the retaining bolts 16 are associated with the Base body 3a, 3b screwed. For this, the Fastening means 26 as shown as in the area of the connecting surfaces 9a, 9b introduced into the base body 3a, 3b Tapped holes in which the retaining bolts are made a threaded shaft 27 provided on them can be screwed in are. The retaining bolts 16 are here of a kind of special screws formed and conveniently have a specially shaped tool attack section 28 - for example a polygonal section - which is the attachment of a screwing tool allows.

Die Gegenbeaufschlagungsfläche 24 befindet sich zweckmäßigerweise an einem nach Art eines Ringbundes umlaufenden Radialvorsprung 31, der über einen schaftartigen Zwischenabschnitt 32 - vorzugsweise unter Zwischenschaltung der Werkzeugangriffspartie 28 - mit dem Gewindeschaft 27 verbunden ist und über diesen schaftartigen Zwischenabschnitt 32 radial vorsteht. Bevorzugt kann der Radialvorsprung 31 wie abgebildet von einem Kopfabschnitt 33 des betreffenden Haltebolzens 16 gebildet sein.The counteracting surface 24 is expediently located on a circumferential radial projection in the manner of a ring collar 31, which has a shaft-like intermediate section 32 - preferably with the interposition of the tool attack part 28 - is connected to the threaded shaft 27 and projects radially beyond this shaft-like intermediate section 32. The radial projection 31 can preferably be as shown from a head section 33 of the relevant holding bolt 16 be educated.

Wie aus Figuren 2 und 3 gut hervorgeht, sind an den beiden Verbindungsflächen 9a, 9b jeweils mehrere und vorzugsweise zwei Haltebolzen 16 angeordnet, die zueinander beabstandet sind. Im Hinblick auf die zentrale Kanalmündung 8a, 8b ist insbesondere vorgesehen, dass sich die beiden Haltebolzen 16 auf einander diametral gegenüberliegenden Seiten der zugeordneten Kanalmündung 8a, 8b befinden, letztere also an einander diametral gegenüberliegenden Seiten flankieren. Die Zentren einer jeweiligen Kanalmündung 8a, 8b und der diese flankierenden Haltebolzen 16 liegen dabei zweckmäßigerweise auf einer gemeinsamen gedachten Verbindungslinie 34, die rechtwinkelig zur Verspannungsrichtung 19 verläuft.As is clear from Figures 2 and 3, are on the two Connection surfaces 9a, 9b each several and preferably two retaining bolts 16 arranged which are spaced apart are. With regard to the central channel mouth 8a, 8b in particular provided that the two retaining bolts 16 on diametrically opposite sides of the associated Channel mouth 8a, 8b are located, so the latter to each other flank diametrically opposite sides. The centers a respective channel mouth 8a, 8b and the flanking them Holding bolts 16 are expediently on one common imaginary connecting line 34 that is rectangular runs to the direction of tension 19.

Die miteinander verspannten Kupplungskörper 17, 18 umgreifen die Haltebolzen 16 zweckmäßigerweise klammerartig, wobei jeder Kupplungskörper für jeden Haltebolzen 16 eine diesen teilweise aufnehmende Vertiefung 35, 36 und eine erste bzw. zweite Beaufschlagungsfläche 22, 23 aufweist. Dementsprechend verfügt beim Ausführungsbeispiel jeder Kupplungskörper 17, 18 über vier Beaufschlagungsflächen 22, 23 mit zugeordneter Vertiefung 35, 36, die den zugeordneten Haltebolzen 16 im miteinander verspannten Zustand ringsum vorzugsweise vollständig umschließen.
Indem die Haltebolzen 16 innerhalb des Umrisses der Verbindungsflächen 9a, 9b plaziert sind, lassen sie sich möglichst nahe im Bereich des Kanalüberganges zwischen dem Durchgangskanal 13 und den Fluidkanälen 4a, 4b plazieren, so dass die entstehenden Verbindungskräfte Fv in unmittelbarer Nachbarschaft der Dichtungen 15 wirksam werden und sich eine zuverlässige Dichtpressung einstellt. Gleichwohl können die Haltebolzen 16 in Randnähe der betreffenden Verbindungsfläche vorgesehen werden, um große Strömungsquerschnitte des Durchgangskanals 13 und der Fluidkanäle 4a, 4b zu ermöglichen. Durch die Verwendung der Haltebolzen lassen sich zudem sehr kompakte Querabmessungen realisieren.The mutually braced coupling bodies 17, 18 expediently surround the retaining bolts 16 in a clamp-like manner, each coupling body having a recess 35, 36 for receiving each retaining bolt 16, and a first or second loading surface 22, 23. Accordingly, in the exemplary embodiment, each coupling body 17, 18 has four contact surfaces 22, 23 with an associated recess 35, 36, which preferably completely surround the associated retaining bolt 16 in the clamped state.
By placing the retaining bolts 16 within the outline of the connecting surfaces 9a, 9b, they can be placed as close as possible in the area of the channel transition between the through-channel 13 and the fluid channels 4a, 4b, so that the connecting forces F v that arise are effective in the immediate vicinity of the seals 15 and there is a reliable sealing pressure. Nevertheless, the retaining bolts 16 can be provided in the vicinity of the edge of the relevant connection surface in order to enable large flow cross sections of the through-channel 13 and the fluid channels 4a, 4b. By using the retaining bolts, very compact transverse dimensions can also be achieved.

Die Haltebolzen 16 der beiderseitigen Verbindungsflächen 9a, 9b sind vorzugsweise so angeordnet, dass sie sich paarweise koaxial gegenüberliegen. Jeder Haltebolzen 16 des einen Basiskörpers 3a fluchtet also in der Verbindungsrichtung 5 mit einem Haltebolzen 16 des anderen Basiskörpers 3b. Dies gewährleistet eine sehr symmetrische Krafteinleitung.The retaining bolts 16 of the connecting surfaces 9a on both sides, 9b are preferably arranged so that they are in pairs opposed coaxially. Each retaining bolt 16 of a base body 3a is also aligned in the connection direction 5 a retaining bolt 16 of the other base body 3b. This ensures a very symmetrical application of force.

Dabei ist vorgesehen, dass die Haltebolzen 16 eines jeweiligen fluchtenden Haltebolzenpaares auch bei verspannten Kupplungskörpern 17, 18 nicht aneinander anliegen, so dass der Verspannungsvorgang nicht beeinträchtigt wird. Es ist im Gegenteil sogar von Vorteil, wenn die in der Verbindungsrichtung 5 gemessene Breite der beiden Kupplungskörper 17, 18 auf die Länge der Haltebolzen 16 so abgestimmt ist, dass auch im verspannten Zustand zwischen den jeweils miteinander fluchtenden Haltebolzen 16 ein Zwischenraum 27 verbleibt, der von den Spannmitteln 25 durchsetzt werden kann.
Diese Spannmittel 25 sind beim Ausführungsbeispiel von Schraubverbindungsmitteln gebildet, wobei jedem miteinander fluchtenden Haltebolzenpaar eine Spannschraube 38 zugeordnet ist, durch die die beiden Kupplungskörper 17, 18 miteinander verspannt werden und die sich dabei jeweils durch einen der Zwischenräume 37 hindurch erstreckt. Dies hat zur Folge, dass die Krafteinleitungslinien der Verbindungskraft Fv und der Spannkraft Fs in unmittelbarer Nähe verlaufen können und sich, wie beim Ausführungsbeispiel, vorzugsweise sogar kreuzen, was eine optimale Kraftumwandlung ohne Gefahr von Verkantungen zur Folge hat.It is provided that the retaining bolts 16 of a respective aligned retaining bolt pair do not abut one another even when the coupling bodies 17, 18 are tensioned, so that the tensioning process is not impaired. On the contrary, it is even advantageous if the width of the two coupling bodies 17, 18 measured in the connection direction 5 is matched to the length of the holding bolts 16 such that a gap 27 remains between the holding bolts 16, which are aligned with one another, even in the tensioned state can be penetrated by the clamping means 25.
In the exemplary embodiment, these clamping means 25 are formed by screw connection means, each clamping bolt pair aligned with one another being assigned a clamping screw 38, by means of which the two coupling bodies 17, 18 are clamped together and which each extend through one of the intermediate spaces 37. This has the consequence that the force introduction lines of the connecting force F v and the clamping force F s can run in the immediate vicinity and, as in the exemplary embodiment, preferably even cross, which results in an optimal force conversion without the risk of jamming.

Beim Ausführungsbeispiel ist vorgesehen, dass zum Anbringen einer jeweiligen Spannschraube 38 der eine Kupplungskörper 18 über ein Durchgangsloch 41 verfügt, das mit einem Gewindeloch 42 des anderen Kupplungskörpers 17 fluchtet, so dass sich die Spannschraube 38 unter Hindurchführung durch das Durchgangsloch 41 in das Gewindeloch 42 einschrauben läßt, wobei sie sich an dem das Durchgangsloch 41 aufweisenden Kupplungskörper 18 mit einem Schraubenkopf 45 abstützen kann. Letzterer kommt zweckmäßigerweise versenkt in einer Erweiterung des Durchgangsloches 41 zu liegen.In the exemplary embodiment it is provided that for attachment a respective clamping screw 38, the one coupling body 18 has a through hole 41 that with a threaded hole 42 of the other coupling body 17 is aligned, so that the Clamping screw 38 passing through the through hole 41 can be screwed into the threaded hole 42, whereby on the coupling body having the through hole 41 18 can support with a screw head 45. The latter expediently sunk in an extension of the Through hole 41 to lie.

Wie aus Figur 5 gut ersichtlich ist, sind die beiden Kupplungskörper 17, 18 zweckmäßigerweise derart ausgebildet, dass sie im miteinander verspannten Zustand zwischen eine jeweilige Gegenbeaufschlagungsfläche 24 und die dieser zugewandte Verbindungsfläche 9a, 9b eintauchen. Dabei ist vorgesehen, dass die Kupplungskörper 17, 18 im miteinander verspannten Zustand aneinander anliegen, wodurch eine Begrenzung der erzielbaren Verbindungskraft Fv erreicht werden kann, um Beschädigungen durch Überbeanspruchungen zu verhindern.As can be clearly seen from FIG. 5, the two coupling bodies 17, 18 are expediently designed such that they are immersed in the mutually clamped state between a respective counter-loading surface 24 and the connecting surface 9a, 9b facing it. It is provided that the coupling bodies 17, 18 bear against one another in the clamped state, as a result of which the achievable connecting force F v can be limited in order to prevent damage due to overstressing.

Wie aus Figur 2 hervorgeht, verläuft der Durchgangskanal 13 zweckmäßigerweise ausschließlich in einem einzigen der Kupplungskörper, wobei er sich vorliegend in dem zweiten Kupplungskörper 18 erstreckt. Auf diese Weise ergibt sich eine den Durchgangskanal 13 ununterbrochen umschließende Kanalwandung und es kann auf Abdichtungsmaßnahmen zwischen den miteinander verspannten Kupplungskörpern 17, 18 verzichtet werden.As can be seen from FIG. 2, the through channel 13 runs expediently only in one of the coupling bodies, in the present case in the second coupling body 18 extends. In this way there is a the through-channel 13 continuously enclosing channel wall and there may be sealing measures between each other braced coupling bodies 17, 18 are dispensed with.

Um gleichwohl einen Durchgangskanal 13 mit großem Strömungsquerschnitt realisieren zu können, wird der Durchgangskanal 13 an der dem ersten Kupplungskörper 17 zugewandten Seite von einer sich auswölbenden Wand 43 des zweiten Kupplungskörpers 18 begrenzt, die in eine komplementäre Vertiefung des ersten Kupplungskörpers 17 eintaucht, der hier eine im wesentlichen U-förmige Gestalt haben kann. Somit lassen sich äußerst kompakte Querabmessungen der Kupplungseinheit 7 bei zusammengefügten Kupplungskörpern 17, 18 erhalten.Around a passage channel 13 with a large flow cross-section To be able to realize the through channel 13 on the side of the first coupling body 17 of a bulging wall 43 of the second coupling body 18 limited in a complementary recess of the first Coupling body 17 immersed, which is essentially one Can have a U-shaped shape. This makes it extremely compact Transverse dimensions of the coupling unit 7 when assembled Coupling bodies 17, 18 obtained.

Bei montierter Kupplungseinheit 7 erstreckt sich somit die zwischen den beiden Kupplungskörpern 17, 18 definierte Fügezone in den den Haltebolzen 16 zugeordneten äußeren Bereichen etwa entlang der gedachten Verbindungslinie 34, um zwischen den Haltebolzen 16 in der Verspannungsrichtung 19 von der besagten Verbindungslinie 34 abzuweichen und, beispielsgemäß in einem Bogen, um den Durchgangskanal 13 herumgeführt zu werden.
Noch nachzutragen ist, dass mit der Verbindungseinrichtung auch Körper anderer Baugruppen als von zur Druckluftaufbereitung dienenden Vorrichtungen miteinander verbindbar sind, beispielsweise Ventilkörper oder Modulkörper von Fluidverteilerplatten.When the coupling unit 7 is mounted, the joining zone defined between the two coupling bodies 17, 18 extends in the outer regions assigned to the retaining bolts 16 approximately along the imaginary connecting line 34 in order to deviate from the said connecting line 34 in the tensioning direction 19 between the retaining bolts 16 and, for example in an arc to be guided around the through channel 13.
It must also be added that bodies of assemblies other than devices used for air conditioning can also be connected to one another with the connecting device, for example valve bodies or module bodies of fluid distributor plates.
