Dieser Gegenanschluß 2 kann jedoch auch beispielsweise durch eine Augenschraube 2b oder eine Umbördelung 2c gebildet sein, wie dies in Fig. 2 dargestellt ist. Als wesentliches Bauteil besitzt der Anschlußadapter 1 ein hülsenförmiges Gehäuse 1a (vgl. auch Fig. 3 und 4) und eine nachfolgend näher beschriebene Umgriffshalterung 3, die das Ende des Gegenanschlusses 2, nämlich hier die Überwurfmutter 2a klammerförmig umgreift.In Fig. 1 is a side view (rotated by 90 °) and partially shown in half section a connector adapter 1 to one counter connection 2 shown here only schematically, namely a hose extending to the left with a union nut 2a is connected. However, this counter connection 2 can also for example by an eyebolt 2b or a flange 2c, as shown in FIG. 2. As The connection adapter 1 has an essential component sleeve-shaped housing 1a (see also Fig. 3 and 4) and a wrap-around bracket 3 described in more detail below, which is the end of the mating connector 2, namely here the union nut 2a embraces in a bracket.

Bei dieser Ausführungsform der Umgriffshalterung 3 gemäß Fig. 1, untere Hälfte, ist die nach unten hin weisende Seite der Umgriffshalterung 3 mittels einer schlitzförmigen Aussparung 3c offen ausgebildet, so daß der Anschlußadapter 1 in einfacher Weise hier von der Oberseite her an den Gegenanschluß 2 angesetzt bzw. übergestülpt werden kann. Dabei schließen sich links von der Überwurfmutter 2a eine Gegenplatte 3a und rechts davon die nachfolgend beschriebenen, an bzw. in dem Gehäuse 1a gelagerten Bauteile 4 bis 6 an, nämlich eine an den Gegenanschluß 2 angepaßte Anschlußkolbenhülse 4, eine Betätigungsvorrichtung 5 und die Befestigung der Gegenplatte 3a in Form von mehreren Schrauben 6. In this embodiment of the wrap-around bracket 3 according to FIG. 1, lower half, is the downward facing side of the Wrapping bracket 3 by means of a slot-shaped recess 3c open design, so that the connection adapter 1 in simple Here from the top to the counter connector 2 can be put on or put on. Doing so close a counter plate 3a to the left of the union nut 2a and to the right of which the ones described below on or in the housing 1a stored components 4 to 6, namely one to the Mating connector 2 adapted connecting piston sleeve 4, one Actuator 5 and the attachment of the counter plate 3a in the form of several screws 6.

Gemäß der Ausführung in Fig. 2 kann der Gegenanschluß 2 bis auf die seitliche Einführ- oder Einfädelöffnung 3c zwischen den Schrauben 6 auch allseitig von der Umgriffshalterung 3 umschlossen sein, so daß für den Gegenanschluß 2 ein Aufnahmeraum 3b in der Umgriffshalterung 3 gebildet ist, in den die Anschlußkolbenhülse 4 zur Freigabe bzw. zum Dichtanschluß axial bewegbar ist, wie die in den beiden Stellungen in Fig. 3 verdeutlicht ist.According to the embodiment in FIG. 2, the mating connector 2 can be up to the lateral insertion or threading opening 3c between the Screws 6 on all sides of the wrap-around bracket 3 be enclosed so that for the counter terminal 2 a Recording space 3b is formed in the wrap-around bracket 3 in the the connecting piston sleeve 4 for release or for sealing connection is axially movable, like that in the two positions in Fig. 3rd is made clear.

In dem Aufnahmeraum 3b der Umgriffshalterung 3 ist die hier linke Stirnseite der Anschlußkolbenhülse 4 mit einer zentral verlaufenden Fluidpassage 4a zum Anschluß axial bewegbar. Die hier nach rechts weisende Seite der Fluidpassage 4a kann mit einem in das Gehäuse 1a eingeschraubten Abschlußstopfen 11 an einen strichliert angedeuteten Prüf- bzw. Füllschlauch angeschlossen werden, so daß dann die hier nach links weisende Stirnseite der Anschlußkolbenhülse 4 in Anschlußstellung mittels einer oder mehreren Dichtungen 8 (vgl. Fig. 2) dichtend an dem Gegenanschluß 2 anliegt.This is here in the receiving space 3b of the wrap-around bracket 3 left end of the connecting piston sleeve 4 with a central extending fluid passage 4a axially movable for connection. The here the right side of the fluid passage 4a can also an end plug 11 screwed into the housing 1a a dashed-line test or filling hose be connected so that the one pointing to the left Front side of the connecting piston sleeve 4 in the connecting position by means of one or more seals 8 (see FIG. 2) sealing on the Counter terminal 2 is present.

Die axiale Bewegung der Anschlußkolbenhülse 4 wird mittels einer Betätigungseinrichtung 5, hier in Form eines seitlich abstehenden Stiftes zur Verriegelung bzw. Freigabe der federbelasteten Anschlußkolbenhülse 4 verwirklicht, wobei sich letztere bei der Betätigung hier nach links zum Aufnahmeraum 3b bewegen würde. Zur verbesserten Bedienbarkeit kann auch eine Exzenterbetätigung oder eine (Unter-)Druckunterstützung mittels eines Druckraumes 10 vorgesehen sein (vgl. Fig. 3 und 4). Dabei wird die Anschlußkolbenhülse 4 innerhalb des Gehäuses 1a bzw. auf dem in Axialrichtung nach innen verlängerten Abschlußstopfen 11 exakt geführt und somit kolbenartig in Axialrichtung zur Gegenplatte 3a oder von dieser weg bewegt.The axial movement of the connecting piston sleeve 4 is by means of a Actuator 5, here in the form of a side protruding pin for locking or releasing the realized spring-loaded connecting piston sleeve 4, whereby the latter when actuated here to the left to the receiving space 3b would move. For improved usability, a Eccentric actuation or (under) pressure support by means of a pressure chamber 10 may be provided (see. Fig. 3 and 4). there the connecting piston sleeve 4 within the housing 1a or on the end plug extended inwards in the axial direction 11 exactly guided and thus piston-like in the axial direction Counter plate 3a or moved away from this.

Bevorzugt weist die Umgriffshalterung 3 an ihrer Stirnseite bzw. an der Gegenplatte 3a mehrere Befestigungsschrauben 6 mit Distanzhülsen 6a und einen mittigen Codier- oder Indexierstift 7 auf, so daß hierdurch vorbestimmte Kennungen zwischen Anschlußadapter 1 und Gegenanschluß 2 ermöglicht werden. Hierdurch kann beispielsweise auch der an den jeweiligen Gegenanschluß 2 anzulegende Prüfdruck vorbestimmt werden. Der in Fig. 2 und 3 dargestellte Indexierstift 7 ist bevorzugt an der Gegenplatte 3a der Umgriffshalterung 3 eingeschraubt, um bei deren Austausch oder gesondert ausgewechselt zu werden.The wrap-around holder 3 preferably has on its end face or on the counter plate 3a with several fastening screws 6 Spacer sleeves 6a and a central coding or indexing pin 7 on, so that hereby predetermined identifiers between Connection adapter 1 and counter connection 2 are made possible. In this way, for example, that of the respective Counterpressure 2 test pressure to be applied can be predetermined. The in 2 and 3 shown indexing pin 7 is preferably on the Counterplate 3a of the wrap-around bracket 3 screwed in at their exchange or to be replaced separately.

An dieser Umgriffsseite der Umgriffshalterung 3 sind mehrere Schrauben 6 jeweils im Eckbereich vorgesehen, so daß hierdurch im Zentrum der Aufnahmeraum 3b der Umgriffshalterung 3 gebildet werden kann. Es sei darauf hingewiesen, daß die im Gehäuse 1a eingeschraubten Befestigungsschrauben 6 in einem gewissen Längenbereich, ggf. mit Austausch der Distanzhülsen 6a, verstellt werden können, so daß hierdurch im Zusammenspiel mit dem Indexierstift 7 jeweils eine sichere und dichte Anlage der Anschlußkolbenhülse 4 an dem Prüfling oder Gegenanschluß 2, z.B. unterschiedlich breite Augenschrauben 2b, auch bei sehr hohem Prüfdruck gewährleistet werden kann.There are several on this wrap-around side of the wrap-around bracket 3 Screws 6 are provided in the corner area, so that this formed in the center of the receiving space 3b of the wrap-around bracket 3 can be. It should be noted that the 1a screwed fastening screws 6 in a certain Length range, possibly with replacement of the spacer sleeves 6a, can be adjusted, so that in cooperation with the indexing pin 7 each a safe and tight system of Connection piston sleeve 4 on the test object or mating connector 2, e.g. eyebolts of different widths 2b, even with very high ones Test pressure can be guaranteed.

In Fig. 2 sind mehrere Anschlußarten des Anschlußadapters 1 zur Verdeutlichung der hohen Variabilität dieser Modulbauweise dargestellt. Wie hieraus ersichtlich ist, sind gegenüber der in Fig. 1 dargestellten Ausführung mit einer Überwurfmutter 2a und daran angepaßter schlitzförmiger Aussparung 3c in der Gegenplatte 3a eine Vielzahl von Kombinationen bei gleichem Grundaufbau des Gehäuses 1a möglich, wobei auch die Anschlußkolbenhülse 4 durch schnellen Austausch (nach Lösen des Abschlußstopfens 11) an den jeweils zu prüfenden Gegenanschluß 2 angepaßt werden kann. Der Austausch der Anschlußkolbenhülse 4 ist im allgemeinen jedoch nur dann erforderlich, wenn die Dichtanlage an den jeweiligen Gegenanschluß 2, 2a, 2b oder 2c stark unterschiedlich sein sollte. Dabei kann jedoch auch nur das Vorderende mit der oder den Dichtungen 8 ausgewechselt werden, um den Anschlußadapter 1 an verschiedene Durchmesser des Gegenanschlusses 2 anzugleichen. In Fig. 2 several types of connection of the connection adapter 1 are Clarification of the high variability of this modular construction shown. As can be seen from this, compared to the in Fig. 1 shown embodiment with a nut 2a and matched slot-shaped recess 3c in the Counter plate 3a a variety of combinations with the same Basic structure of the housing 1a possible, the Connection piston sleeve 4 by quick exchange (after loosening the End plug 11) to the counter connection to be tested in each case 2 can be adjusted. Replacing the connecting piston sleeve 4 is generally only required if the Sealing system to the respective counter connection 2, 2a, 2b or 2c should be very different. However, it can only the front end with the or the seals 8 replaced be to the connection adapter 1 to different diameters of Align mating connector 2.

Das Gehäuse 1a mit der Betätigungseinrichtung 5, den Schrauben 6 und dem eingeschraubten Abschlußstopfen 11 bleibt als Grundmodul jeweils gleich, ebenso die Anschlußabmessungen der Wechselteile, nämlich das Bohrungsbild der Grundplatte 3a und die Außendurchmesser der in dem Gehäuse 1a axial gelagerten Anschlußkolbenhülse 4. Hierdurch ergibt sich eine wesentliche Vereinfachung bei der Bauteileherstellung und der Montage.The housing 1a with the actuating device 5, the screws 6 and the screwed plug 11 remains as a basic module each the same, as well as the connection dimensions of the interchangeable parts, namely the hole pattern of the base plate 3a and the Outside diameter of those axially supported in the housing 1a Connection piston sleeve 4. This results in an essential Simplification in component manufacture and assembly.

In Fig. 3 ist die Axialbewegung der Anschlußkolbenhülse 4 verdeutlicht, die durch Betätigung und ggf. Druckunterstützung ausgelöst wird. An den Druckraum 10 ist hier über eine Bohrung 11' ein Steuerdruck anlegbar, so daß bei Aktivierung über die Betätigungseinrichtung 5 sich die hier geschwärzt gezeichnete Anschlußkolbenhülse 4 gegenüber der Umgriffshalterung 3 in das Gehäuse 1a zurückzieht (untere Hälfte von Fig. 3).3 is the axial movement of the connecting piston sleeve 4 clarifies that by actuation and possibly pressure support is triggered. To the pressure chamber 10 is here via a bore 11 'a control pressure can be applied so that when activated via the Actuator 5 which is drawn here blackened Connection piston sleeve 4 in relation to the wrap-around bracket 3 in the Retracts housing 1a (lower half of Fig. 3).

Wenn der Steuerdruck (hier Unterdruck) abgeschaltet wird, kann sich die Anschlußkolbenhülse 4 unter Beaufschlagung einer in der Fluidpassage 4a angeordneten Feder 9 nach links in den rahmenartigen Aufnahmeraum 3b der Umgriffshalterung 3 bewegen, wobei zugleich durch einen durchmessergrößeren Ringabsatz 12 (vgl. auch Fig. 2, oben) eine Anpreßverstärkung der Anschlußkolbenhülse 4 an dem Gegenanschluß 2 erzielt wird, wenn die Fluidpassage 4a des Anschlußadapters 1 mit Prüfdruck beaufschlagt ist. Anstatt oder ergänzend zu der Feder 9 kann auch der Druckraum 10 als doppeltwirkender Zylinder ausgebildet sein, also sowohl zur Anpreßbewegung als auch zur Rückzugsbewegung der Anschlußkolbenhülse 4 dienen.If the control pressure (here vacuum) is switched off, the connecting piston sleeve 4 under the action of one in the Fluid passage 4a arranged spring 9 to the left in the move the frame-like receiving space 3b of the wrap-around bracket 3, at the same time by a ring shoulder 12 of larger diameter (see also Fig. 2, above) a contact pressure gain Connection piston sleeve 4 is achieved at the counter-connection 2 when the fluid passage 4a of the connection adapter 1 with test pressure is acted upon. Instead of or in addition to the spring 9 can the pressure chamber 10 is also designed as a double-acting cylinder be, both for the contact movement and for Retracting movement of the connecting piston sleeve 4 serve.

In der in Fig. 3 oben gezeigten Anschlußstellung liegt somit die Anschlußkolbenhülse 4 zusammen mit dem stirnseitigen Dichtring 8 an den Gegenanschluß 2 an, wobei sich durch den größeren Durchmesser des Ringabsatzes 12 um die Feder 9 herum eine zusätzliche Anpreßkraft in Axialrichtung ergibt. Somit wird der Druckraum 10 nicht unbedingt benötigt, da die Anpreßkraft des Prüfmediums in Verbindung mit der Druckunterstützung am Ringabsatz 12 während des Prüfvorganges zur sicheren Abdichtung am Gegenanschluß 2 ausreicht. Dabei ist in der Anschlußkolbenhülse 4 bevorzugt auch ein Rückschlagventil integriert.In the connection position shown in Fig. 3 above is thus Connection piston sleeve 4 together with the front sealing ring 8 to the counter terminal 2, whereby the larger Diameter of the ring shoulder 12 around the spring 9 around results in additional contact pressure in the axial direction. Thus the Pressure chamber 10 is not absolutely necessary, since the contact pressure of the Test medium in connection with the pressure support on Ring shoulder 12 during the test process for a secure seal at the counter terminal 2 is sufficient. It is in the Connection piston sleeve 4 preferably also a check valve integrated.

Der Dichtring 8 ist hierbei am vorderen Stirnabsatz der Anschlußkolbenhülse 4 ein- oder aufgesetzt, wobei auch an dem Indexierstift 7 der Gegenplatte 3a ein derartiger Dichtring vorgesehen ist, um die dazwischen fixierte Augenschraube 2b beidseitig abzudichten. Der Dichtring 8 am Vorderteil der Anschlußkolbenhülse 4 ist dabei bevorzugt austauschbar befestigt, insbesondere mit einem Ring aufschraubbar, wie dies in Fig. 2, oben, angedeutet ist, so daß auf einfache Weise eine Anpassung an unterschiedliche Gegenanschlüsse 2 vorgenommen werden kann.The sealing ring 8 is here on the front heel Connection piston sleeve 4 inserted or placed, also on the Indexing pin 7 of the counter plate 3 a such a sealing ring is provided to the eyebolt 2b fixed in between to seal on both sides. The sealing ring 8 on the front part of the Connection piston sleeve 4 is preferably interchangeable attached, especially screwed with a ring, like this in Fig. 2, above, is indicated, so that a simple Adaptation to different counter connections 2 made can be.

Aus dem Vergleich zwischen den Fig. 1 und 3 mit grundsätzlich gleichem Aufbau des Anschlußadapters 1 ist ersichtlich, daß die Gegenanschlüsse 2a bzw. 2b eng in dem Aufnahmeraum 3b der Umgriffshalterung 3 aufgenommen sind, so daß hierdurch eine sehr stabile Bauweise erreichbar ist. Zudem läßt sich der Anschlußadapter 1 auf einfache Weise zerlegen, indem die Befestigungsschrauben 6 und ggf. die Distanzhülsen 6a gelöst werden, um dann die entsprechende Gegenplatte 3a ( mittlere Spalte in Fig. 2) zu montieren.Basically from the comparison between FIGS. 1 and 3 same structure of the connection adapter 1 it can be seen that the Mating connections 2a and 2b closely in the receiving space 3b Wrapping bracket 3 are added, so that this makes a very stable construction is achievable. In addition, the Disassemble connection adapter 1 in a simple manner by the Fixing screws 6 and possibly the spacers 6a loosened then the corresponding counter plate 3a (middle To assemble column in Fig. 2).

Dabei kann in Anpassung an den jeweiligen Gegenanschluß 2 auch die Anschlußkolbenhülse 4 ausgetauscht werden, sofern der einfachere Austausch an der vorderen Stirnseite nicht ausreichen sollte, da auch der Abschlußstopfen 11 einfach und schnell vom Gehäuse 1a gelöst werden kann, um zur Anpassung an den jeweils zu prüfenden Gegenanschluß 2 ( z.B. auch ein in Fig. 2 unten dargestellter, relativ großer Ventilschieber) eine einfache Demontage bzw. in umgekehrter Weise bei der Herstellung eine einfache, kostengünstige Montage zu ermöglichen.It can also adapt to the respective counter terminal 2 the connecting piston sleeve 4 are replaced, if the simple replacement on the front end is not sufficient should, since the end plug 11 easily and quickly from Housing 1a can be detached in order to adapt to each Counter-connection 2 to be checked (e.g. also one in Fig. 2 below shown, relatively large valve spool) a simple one Disassembly or in reverse in the manufacture of a enable simple, inexpensive installation.

Gemeinsam ist allen alternativen Ausführungsformen, daß die Umgriffshalterung 3 durch die Gegenplatte 3a mit gleichen Anschlußabmessungen für die Befestigungsschrauben 6 weitgehend geschlossen ist, so daß die Umgriffshalterung 3 eng über den Gegenanschluß 2 gestülpt ist.Common to all alternative embodiments is that the Wrapping bracket 3 through the counter plate 3a with the same Connection dimensions for the mounting screws 6 largely is closed, so that the wrap-around bracket 3 closely over the Counter connector 2 is put over.

Hierdurch ergibt sich eine große Festigkeit der Umgriffshalterung 3, so daß diese rahmenartig geschlossene Bauweise gerade bei Schlauchleitungen mit Überwurfmuttern 2a mit zusätzlicher axialer Festlegung in der schlitzförmigen Aussparung 3c für viele Anwendungsfälle von besonderem Vorteil ist.This results in a great strength of the Wrapping bracket 3 so that it is closed like a frame Construction especially with hose lines with union nuts 2a additional axial definition in the slit-shaped Recess 3c is particularly advantageous for many applications is.

In Fig. 4 ist eine stehende Ausführung des Anschlußadapters dargestellt, wobei die Bauteile mit der gleichen Funktion wie in den Figuren 1 bis 3 mit den gleichen Bezugsziffern versehen sind. Dies ist insbesondere das hier stehend angeordnete Gehäuse 1a, in dem die Anschlußkolbenhülse 4 mit dem Fluiddurchlaß 4a axial beweglich ist. Die Anschlußkolbenhülse 4 wird hierzu von einer hier außenliegenden Feder 9 nach oben hin beaufschlagt. Die Umgriffshalterung 3 in Form einer hier unteren Gegenplatte 3a ist wiederum mit strichliert angedeuteten Schrauben 6 schnell wechselbar mit dem Gehäuse 1a verbunden. Hierdurch kann je nach zu prüfendem Gegenanschluß eine Anpassung daran vorgenommen werden. Zudem ist hierbei wiederum ein Kodier- oder Indexierstift 7 vorgesehen, der zudem mit Dichtungen 7a versehen ist. Dieser Indexierstift 7 ist dabei auf einem Schlitten 20 gelagert, der einen Betätigungsstift 21 aufweist. In der hier dargestellten Betätigungsfunktion beaufschlagt dieser Betätigungsstift 21 ein Schaltventil 22, das in eine entsprechende Bohrung 23 eingesetzt ist. In dieser Stellung wird der Druckraum 10 über der Anschlußkolbenhülse 4 mit Druck beaufschlagt, so daß die Anschlußkolbenhülse 4 mit der vorderen Dichtung 8 an den Gegenanschluß 2 heranfährt. Hierzu ist die Anschlußkolbenhülse 4 mit mehreren Dichtungen 18 versehen. Durch diese teil-automatisierte Ausführung des Anschlußadapters wird somit gleichzeitig mit dem Einlegen des Gegenanschlusses 2 auf den Schlitten 20 die Anschlußstellung in einfacher Weise hergestellt.4 is a standing version of the connection adapter shown, the components with the same function as in Figures 1 to 3 provided with the same reference numerals are. This is in particular the housing arranged upright here 1a, in which the connecting piston sleeve 4 with the fluid passage 4a is axially movable. The connecting piston sleeve 4 is from a spring 9 located here upwards. The wrap-around bracket 3 in the form of a lower counterplate here 3a is again fast with screws 6 indicated by dashed lines interchangeably connected to the housing 1a. This can vary depending on an adjustment to the counter connection to be tested become. In addition, here is a coding or Indexing pin 7 is provided, which is also provided with seals 7a is. This indexing pin 7 is on a carriage 20 stored, which has an actuating pin 21. In the here Actuating function shown acts on this Actuating pin 21, a switching valve 22, which in a corresponding hole 23 is inserted. In this position the pressure chamber 10 above the connecting piston sleeve 4 with pressure acts so that the connecting piston sleeve 4 with the front Seal 8 moves up to the counter connection 2. For this is the Connection sleeve 4 provided with several seals 18. By this semi-automated version of the connection adapter will thus simultaneously with the insertion of the mating connector 2 the carriage 20 the connection position in a simple manner manufactured.
