Während die standardmäßigen Steuereinheiten stets nur einen Bestückungsplatz belegen, erstreckt sich die Zwischenplatte der Sonder-Steuereinheit über mindestens zwei aneinander angrenzende Bestückungsplätze hinweg. Dadurch steht für die interne Zwischenplatten-Kanalanordnung eine verhältnismäßig große Baubreite der Zwischenplatte zur Verfügung, die die Verwirklichung auch komplexer fluidischer Schaltungen ermöglicht, das Ganze in Verbindung mit einer bei Bedarf geringen Bauhöhe der Zwischenplatte. Besonders vorteilhaft ist die Möglichkeit, einen oder mehrere der an den mehreren überdeckten Bestückungsplätzen ausmündenden Ventilträgerkanäle in eine fluidische Schaltung einzubeziehen, die durch die Zwischenplatten-Kanalanordnung und das mindestens eine an der Zwischenplatte angeordnete Steuerventil der Sonder-Steuereinheit definiert wird.While the standard control units always occupy only one placement space, the intermediate plate of the special control unit extends over at least two mutually adjacent placement places. As a result, a relatively large width of the intermediate plate is available for the internal intermediate plate channel arrangement, which allows the realization of even complex fluidic circuits, the whole in conjunction with a small if necessary height of the intermediate plate. Particularly advantageous is the possibility of incorporating one or more of the valve carrier channels opening out at the several covered placement stations into a fluidic circuit which is defined by the intermediate plate channel arrangement and the at least one control valve of the special control unit arranged on the intermediate plate.
Als besonders zweckmäßig hat es sich erwiesen, die Abmessungen der Zwischenplatte der Sonder-Steuereinheit so zu wählen, dass sie genau zwei einander benachbarte Bestückungsplätze überdeckt.It has proven particularly expedient to choose the dimensions of the intermediate plate of the special control unit such that it covers exactly two mutually adjacent placement places.
Verfügt die Bestückungsfläche über eine entsprechend große Anzahl von Bestückungsplätzen, können daran gleichzeitig mehrere Sonder-Steuereinheiten montiert sein oder eine Mischung aus mindestens einer Sonder-Steuereinheit und mindestens einer nur einen Bestückungsplatz bedeckenden konventionellen Steuereinheit. Daraus resultiert ein modularer Aufbau mit vielfältigen Ausstattungsmöglichkeiten der Ventileinrichtung und folglich einer hohen Variabilität die Einsatzmöglichkeiten betreffend.If the assembly area has a correspondingly large number of placement locations, several special control units can be mounted on it at the same time or a mixture of at least one special control unit and at least one conventional control unit covering only one placement space. This results in a modular design with a variety of equipment options of the valve device and consequently a high variability regarding the possible applications.
Vorteilhafte Weiterbildungen der Erfindung gehen aus den Unteransprüchen hervor.Advantageous developments of the invention will become apparent from the dependent claims.
Als besonders zweckmäßig wird eine Ausgestaltung der Ventileinrichtung angesehen, bei der die Zwischenplatten-Kanalanordnung der mindestens einen Sonder-Steuereinheit mindestens einen Verbindungskanal umfasst, der mindestens zwei zu der Sonder-Steuereinheit gehörende Steuerventile miteinander verbindet. Zusätzlich oder alternativ kann mindestens ein Verbindungskanal der Zwischenplatten-Kanalanordnung wenigstens zwei Ventilträgerkanäle miteinander verbinden, die an unterschiedlichen der überdeckten Bestückungsplätze ausmünden.Particularly expedient is an embodiment of the valve device is considered, in which the intermediate plate channel arrangement of at least one special control unit comprises at least one connecting channel which connects at least two belonging to the special control unit control valves together. In addition or as an alternative, at least one connecting channel of the intermediate plate channel arrangement can connect at least two valve carrier channels which terminate at different covered insertion positions.
Unter Verwendung mindestens eines solchen Verbindungskanals besteht beispielsweise die Möglichkeit, zwei Steuerventile so miteinander zu verschalten, dass ein angeschlossener individueller Arbeitskanal der Ventilträger-Kanalanordnung nur dann mit Druckmedium versorgt wird, wenn gleichzeitig beide Steuerventile betätigt sind. Dadurch lässt sich eine für die Ansteuerung von Pressen geeignete Sicherheitsschaltung sehr einfach und mit kompakter Bauweise realisieren.By using at least one such connecting channel, for example, it is possible to connect two control valves with one another such that a connected individual working channel of the valve carrier channel arrangement is supplied with pressure medium only if both control valves are actuated at the same time. As a result, a safety circuit suitable for controlling presses can be realized very simply and with a compact design.
Es besteht ferner die Möglichkeit, einen Verbindungskanal mit einem derartigen Verlauf zu versehen, dass er gleichzeitig mit an mehreren Bestückungsplätzen ausmündenden Arbeitskanälen der Ventilträger-Kanalanordnung kommuniziert. Dies ermöglicht eine gleichzeitige Fluidversorgung mehrerer Verbraucher oder, wenn die Arbeitskanäle zusammengeschlossen werden, die Versorgung eines Verbrauchers mit einem erhöhten Durchfluss.There is also the possibility of providing a connecting channel with such a course that it simultaneously communicates with working channels of the valve carrier channel arrangement opening out at a plurality of loading stations. This allows a simultaneous supply of fluid to multiple consumers or, when the working channels are interconnected, the supply of a consumer with an increased flow.
Insbesondere besteht auch die Möglichkeit, die Zwischenplatte mit mindestens einer Vakuumerzeugereinrichtung auszustatten. Bei entsprechender Ausgestaltung der Zwischenplatten-Kanalanordnung kann ein von einer einzigen Vakuumerzeugereinrichtung hervorgerufener Unterdruck gleichzeitig an mehreren Arbeitskanälen anliegen und abgegriffen werden. Ebenso können mittels eines einzigen Steuerventils gleichzeitig mehrere Vakuumerzeugereinrichtungen angesteuert werden. Die Vakuumerzeugereinrichtungen beinhalten insbesondere eine nach dem Ejektorprinzip arbeitende Saugdüse.In particular, it is also possible to equip the intermediate plate with at least one vacuum generating device. With appropriate design of the intermediate plate channel arrangement For example, a negative pressure caused by a single vacuum generator device can simultaneously be applied to a plurality of working channels and tapped off. Likewise, a plurality of vacuum generating devices can be controlled simultaneously by means of a single control valve. The vacuum generating devices include in particular a working according to the ejector principle suction nozzle.

Die in Ihrer Gesamtheit mit Bezugsziffer 1 bezeichnete Ventileinrichtung ist als Ventilbatterie konzipiert und enthält einen Ventilträger 2, der gleichzeitig mit einer Mehrzahl von Steuereinheiten 3 bestückbar ist, die jeweils mindestens ein, bevorzugt elektrisch betätigbares, Steuerventil 4 beinhalten.The designated in its entirety by reference numeral 1 valve device is designed as a valve manifold and includes a
Die Steuerventile 4 beinhalten einen mit einem nicht weiter dargestellten beweglichen Ventilglied ausgestatteten Hauptventilteil 5 und mindestens einen diesem zugeordneten Antriebsteil 6. Der Antriebsteil 6 kann elektrisch aktiviert werden und ruft den jeweils gewünschten Schaltzustand des Hauptventilteils 5 hervor. Bei dem Antriebsteil 6 handelt es sich in Verbindung mit einem direkt gesteuerten Steuerventil 4 insbesondere um einen Elektromagnet und im Falle eines vorgesteuerten Steuerventils 4 um ein elektrisch betätigbares Vorsteuerventil, insbesondere ein Magnetventil.

Die Außenfläche des Ventilträgers 2 bildet eine bevorzugt ebene Bestückungsfläche 7, an die die Steuereinheiten 3, bevorzugt lösbar, anbaubar sind. Die Bestückungsfläche 7 ist hierbei in mehrere in einer durch einen Doppelpfeil angedeuteten Reihenrichtung 8 aufeinanderfolgende Bestückungsplätze 12 eingeteilt, die zur Bestückung mit den Steuereinheiten 3 nutzbar sind. Die Reihenrichtung 8 fällt insbesondere mit der Längsachse des Ventilträgers 2 zusammen.The outer surface of the
Die Steuereinheiten 3 haben zweckmäßigerweise eine längliche Gestalt. Ihre Längsachse 13 verläuft rechtwinkelig zu der Reihenrichtung 8. Gleiches gilt auch für die jeweils länglichen Bestückungsplätze 12.The control units 3 expediently have an elongated shape. Its
Der Ventilträger 2 ist von einer in ihrer Gesamtheit mit Bezugsziffer 14 bezeichneten, sich aus einer Mehrzahl von Ventilträgerkanälen 15 zusammensetzenden Ventilträger-Kanalanordnung 14 durchsetzt. Unter den Ventilträgerkanälen 15 befindet sich zweckmäßigerweise mindestens ein mit einer externen Druckquelle P verbindbarer Speisekanal 15a und mindestens ein mit einer Drucksenke R, S - insbesondere die Atmosphäre - verbindbarer Abführkanal 15b, 15c. Exemplarisch sind zwei zueinander parallele Abführkanäle 15b, 15c vorhanden, um vor allem bei Steuerventilen 4 mit Vierwege- oder Fünfwegefunktionalität eine optimale Fluidabfuhr zu ermöglichen. Der Speisekanal 15a und die Abführkanäle 15b, 15c erstrecken sich im Innern des Ventilträgers 2 in der Reihenrichtung 8, wobei jeder von ihnen zu jedem Bestückungsplatz 12 ausmündet. Die entsprechenden Kanalmündungen sind durch Bezugsziffern 15a', 15b', 15c' gekennzeichnet.The
Unter den Ventilträgerkanälen 15 befinden sich außerdem Arbeitskanäle 15d, 15e. Während die Speisekanäle 15a, 15b, 15c sämtlichen Bestückungsplätzen 12 gemeinsam zugeordnet sind, man also von einem gemeinsamen Speisekanal 15a und von gemeinsamen Abführkanälen 15b, 15c sprechen kann, sind die Arbeitskanäle 15d, 15e als individuelle Kanäle ausgebildet, wobei zu jedem Bestückungsplatz 12 ein individueller erster Arbeitskanal 15d und insbesondere auch ein individueller zweiter Arbeitskanal 15e ausmündet. Die zugehörigen Kanalmündungen sind durch Bezugsziffern 15d', 15e' kenntlich gemacht. Diese individuellen Arbeitskanäle 15d, 15e sind innerhalb des Ventilträgers 2 nicht miteinander verbunden.Under the
An ihren den Bestückungsplätzen 12 entgegengesetzten Enden münden die Arbeitskanäle 15d, 15e über je eine das Anschließen eines Verbrauchers ermöglichende Verbraucher-Anschlussöffnung 16 zu einer bezüglich der Bestückungsfläche 7 gesonderten Außenfläche des Ventilträgers 2 aus, die im Folgenden als Verbraucher-Anschlussfläche 17 bezeichnet sei. Den Verbraucher-Anschlussöffnungen 16 sind nicht weiter gezeigte Anschlussmittel zugeordnet, an denen jeweils eine zu dem Verbraucher führende Fluidleitung, insbesondere lösbar, angeschlossen werden kann. Bei den Anschlussmitteln handelt es sich beispielsweise um Gewinde oder Steckverbinder.At their positions opposite the
Bevorzugt ist die Verbraucher-Anschlussfläche 17 rechtwinkelig zu der Bestückungsfläche 7 orientiert. Die Verbraucher-Anschlussöffnungen 16 der zum jeweils gleichen Bestückungsplatz 12 führenden Arbeitskanäle 15d, 15e sind vorzugsweise in der durch einen Doppelpfeil angedeuteten Höhenrichtung 18 der Ventileinrichtung 1 übereinander angeordnet, wobei die Höhenrichtung 18 rechtwinkelig zu der Bestückungsfläche 7 orientiert ist.Preferably, the
Die Kanalmündungen 15a' - 15e' bilden an sämtlichen Bestückungsplätzen 12 übereinstimmende Mündungsmuster. Die Mündungsmuster können insbesondere den Normen ISO 5599-2 oder ISO 15407 entsprechen.The
Anstelle zweier individueller Arbeitskanäle 15d, 15e kann den einzelnen Bestückungsplätzen 12 bei Bedarf auch nur ein individueller Arbeitskanal zugeordnet sein.Instead of two
Zur Vereinfachung sind die diversen Kanäle in
Während der Ventilträger 2 prinzipiell einteilig ausgeführt sein kann, setzt er sich bei den Ausführungsbeispielen jeweils aus mehreren in der Reihenrichtung 8 unter Abdichtung aneinandergesetzten Ventilträgersegmenten 22 zusammen. Sie können, entsprechend der gewünschten Baulänge des Ventilträgers 2, in variabler Anzahl miteinander kombiniert werden.While the
Bei den Ausführungsbeispielen definiert jedes Ventilträgersegment 22 zwei in der Reihenrichtung 8 direkt nebeneinander angeordnete Bestückungsplätze 12. Sie gehen insbesondere ansatzlos ineinander über.In the exemplary embodiments, each
Der Übersichtlichkeit wegen sind in der Zeichnung die Übergangsbereiche zwischen benachbarten Bestückungsplätzen 12 durch strichpunktierte Linien 23 kenntlich gemacht.For the sake of clarity, the transitional areas between adjacent placement places 12 are indicated by
Jeder Bestückungsplatz 12 eignet sich grundsätzlich zur Einzelbestückung mittels einer ausschließlich ihm spezifisch zugeordneten Steuereinheit 3, die der besseren Unterscheidung wegen im Folgenden als Standard-Steuereinheit 3a bezeichnet sei. Die in der Reihenrichtung 8 gemessene Breite jeder Standard-Steuereinheit 3a übersteigt nicht die entsprechend gemessene Breite des zugeordneten Bestückungsplatzes 12, wobei insbesondere im Wesentlichen die gleiche Breite vorliegt. Bei dem gezeigten Ausführungsbeispiel können somit auf jedem Ventilträgersegment 22 prinzipiell zwei Standard-Steuereinheiten 3a gleichzeitig platziert werden.Each
Die Standard-Steuereinheiten 3a verfügen über nicht weiter dargestellte interne Kanäle, die zur der dem Bestückungsplatz 12 zugewandten Grundfläche so ausmünden, dass im montierten Zustand eine zuordnungsrichtige Verbindung zu den am betreffenden Bestückungsplatz 12 ausmündenden Ventilträgerkanälen 15 stattfindet.The standard control units 3 a have internal channels (not shown further) which open out to the base area facing the
Die Standard-Steuereinheit 3a kann im einfachsten Fall aus allein einem Steuerventil 4 bestehen. In
Mindestens eine Steuereinheit 3 der Ventileinrichtung 1 - im Folgenden als Sonder-Steuereinheit 3b bezeichnet - weicht breitenmäßig vom Rastermaß der Bestückungsplätze 12 und mithin auch demjenigen der Standard-Steuereinheiten 3a ab, indem seine Breite insbesondere einem ganzzahligen Vielfachen der in der Reihenrichtung 8 gemessenen Breite eines Bestückungsplatzes 12 entspricht. Besonders vorteilhaft wird hierbei die bei den Ausführungsbeispielen realisierte doppelte Breite eines Bestückungsplatzes 12 angesehen.At least one control unit 3 of the valve device 1-referred to below as a special control unit 3b-deviates in width from the pitch of the
Anhand einerseits
An dieser Stelle sei erwähnt, dass ohne Weiteres gleichzeitig unterschiedliche Typen von Sonder-Steuereinheiten 3b an ein und derselben Bestückungsfläche 7 der Ventileinrichtung 1 montiert sein können. Es ist ferner möglich, die gesamte Bestückungsfläche 7 ausschließlich mit Sonder-Steuereinheiten 3b zu bestücken oder aber mit einer Mischung aus einer beliebigen Anzahl von Sonder-Steuereinheiten 3b und Standard-Steuereinheiten 3a. Dies ermöglicht eine variable Ausstattung der Ventileinrichtung 1 unter Berücksichtigung der jeweiligen Einsatzbedingungen.At this point it should be mentioned that different types of special control units 3b can be mounted on one and the same mounting
Die Sonder-Steuereinheit 3b enthält eine mindestens ein Steuerventil 4 tragende Zwischenplatte 24. Soweit im Folgenden allgemein von einer Zwischenplatte die Rede ist, ist diejenige einer Sonder-Steuereinheit 3b gemeint. Sofern eine Bezugnahme auf die Zwischenplatte 23 einer Standard-Steuereinheit 3a beabsichtigt ist, wird dies explizit erwähnt.The special control unit 3b contains an
Die Zwischenplatte 24 ist mit ihrer Unterseite 25 voraus an die Bestückungsfläche 7 angesetzt, wobei sie aufgrund ihrer entsprechend großen Breite zwei unmittelbar nebeneinanderliegende Bestückungsplätze 12 der Bestückungsfläche 7 überdeckt. Ihre in der Reihenrichtung 8 gemessene Breite entspricht der doppelten Breite eines Bestückungsplatzes 12, wobei anzumerken ist, dass beim Ausführungsbeispiel sämtliche Bestückungsplätze 12 über die gleichen Abmessungen verfügen. Vorzugsweise besitzt jeder Bestückungsplatz überdies einen rechteckigen Umriss.The
Die Zwischenplatte 24 kann bei entsprechend größerer Breite auch mehr als zwei Bestückungsplätze 12 abdecken.The
Mindestens ein Steuerventil 4 könnte prinzipiell stirnseitig an der bevorzugt quaderförmigen Zwischenplatte 24 angebracht sein. Vorgezogen wird allerdings die gezeigte Bauform mit an der dem Ventilträger 2 entgegengesetzten Oberseite 26 der Zwischenplatte 24 installiertem mindestens einem Steuerventil 4. Man kann hierbei von einer Höhenverkettung sprechen.At least one
Bei dem Ausführungsbeispiel der
Bei dem Ausführungsbeispiel der
Die Zwischenplatte 24 jeder Sonder-Steuereinheit 3b ist von einer allgemein mit Bezugsziffer 28 bezeichneten Zwischenplatten-Kanalanordnung durchsetzt, die sich aus einer Vielzahl von in geeigneter Weise verlaufenden Zwischenplattenkanälen 32 zusammensetzt. Mit einigen der Zwischenplattenkanäle 32 mündet die Zwischenplatten-Kanalanordnung 28 derart verteilt an der Unterseite 25 der Zwischenplatte 24 aus, dass verschiedene Kanalverbindungen mit den an den überdeckten Bestückungsplätzen 12 ausmündenden Ventilträgerkanälen 12 entstehen.The
Auf diese Weise kann im Bereich jedes von der Zwischenplatte 24 überdeckten Bestückungsplatzes 12 eine Fluidverbindung zwischen Ventilträgerkanälen 15 und Zwischenplattenkanälen 32 stattfinden. Die Kanalverknüpfung ist also nicht auf die Breite eines einzigen Bestückungsplatzes 12 begrenzt, sondern kann sich über eine größere Breite erstrecken.In this way, a fluid connection between
Zumindest einige der Zwischenplattenkanäle 32 münden (auch) zu dem mindestens einen Ventilmontageplatz 27 aus und stehen mit Ventilkanälen 33 des dort jeweils montierten Steuerventils 4 in Fluidverbindung. Die Ventilkanäle 33 münden so an der der Zwischenplatte 24 zugewandten Unterseite des betreffenden Steuerventils 4 aus, dass ein fluchtender Übergang zu den am Ventilmontageplatz 27 vorhandenen Kanalmündungen der Zwischenplattenkanäle 32 erfolgt.At least some of the intermediate plate channels 32 open (also) to the at least one
Entsprechend der gewählten Ausgestaltung der Zwischenplatten-Kanalanordnung 28 und der Anzahl der vorhandenen Steuerventile 4 kann innerhalb einer Sonder-Steuereinheit 3b eine für einen speziellen Anwendungsfall konzipierte fluidische Schaltung realisiert werden. Da in diese Schaltung zu mehreren Bestückungsplätzen 12 ausmündende Ventilträgerkanäle 15 einbezogen werden können, lassen sich auf engstem Raum auch sehr komplexe und anspruchsvolle Schaltungen realisieren, ganz ohne zusätzliche externe Leitungsverbindungen.According to the selected configuration of the intermediate
Beispielsweise zeichnet sich die Sonder-Steuereinheit 3b des Ausführungsbeispiels der
Ein erster (32a) dieser beiden Verbindungskanäle kommuniziert insbesondere mit zwei zu unterschiedlichen Bestückungsplätzen 12 ausmündenden ersten Arbeitskanälen 15d und ist im Übrigen über einen weiteren Zwischenplattenkanal 32c derart an das einzige Steuerventil 4 angeschlossen, dass er durch dieses, bei entsprechender Schaltstellung, mit Druckmedium aus dem gemeinsamen Speisekanal 15a versorgt werden kann. Auf diese Weise besteht die Möglichkeit, einen gleichzeitig an die Verbraucher-Anschlussöffnungen 16 beider erster Arbeitskanäle 15d angeschlossenen Verbraucher mit höherem Durchfluss zu versorgen oder aber unterschiedliche Verbraucher verzögerungsfrei gleichzeitig mit Druckmedium zu beaufschlagen.A first one (32a) of these two connection channels communicates in particular with two
Speziell wenn ein relativ hoher Fluiddurchsatz gewünscht ist, kann ein zweiter Verbindungskanal 32b so an der Unterseite 25 ausmünden, dass er an unterschiedlichen Bestückungsplätzen 12 beide Male mit dem Speisekanal 15a kommuniziert. Ein weiterer Zwischenplattenkanal 32d schließt den zweiten Verbindungskanal 32b an das Steuerventil 4 an.Especially if a relatively high fluid throughput is desired, a second connection channel 32b can open out at the
In der nicht dargestellten Offenstellung des Steuerventils 4 wird Druckmedium aus dem Speisekanal 15a über den zweiten Verbindungskanal 32b und den darauf folgenden weiteren Zwischenplattenkanal 32d in den weiteren Zwischenplattenkanal 32c eingespeist, von wo aus es über den ersten Verbindungskanal 32a in die beiden ersten Arbeitskanäle 15d überströmt.In the open position of the
Ein als Rückführkanal 32e ausgebildeter Zwischenplattenkanal 32 verläuft zwischen dem Ventilmontageplatz 27 und der Unterseite 25 und verbindet das Steuerventil 4 mit einem Abführkanal 15b. Auf diese Weise kann die Fluidrückführung vom jeweils angeschlossenen Verbraucher stattfinden, wenn das Steuerventil 4 die abgebildete Schließstellung einnimmt.An intermediate plate channel 32 designed as a return channel 32e extends between the
Je nach Anwendung, könnte auf den ersten oder zweiten Verbindungskanal 32a, 32b auch verzichtet werden.Depending on the application, the first or second connection channel 32a, 32b could also be dispensed with.
Ist die Zwischenplatte 24 mit mindestens einer Vakuumerzeugereinrichtung 34 ausgestattet, die über das Steuerventil 4 mit Druckluft gespeist wird, kann an den entsprechend angeschlossenen ersten und/oder zweiten Arbeitskanälen 15b, 15e ein Unterdruck abgegriffen werden. Durch einen modifizierten Verlauf des ersten Verbindungskanals 32a können gleichzeitig zwei Arbeitskanäle 15d an ein und dieselbe Vakuumerzeugereinrichtung 34 angeschlossen sein.If the
Die Vakuumerzeugereinrichtung 34 arbeitet insbesondere nach dem Ejektorprinzip und enthält eine Saugdüse, die einen Unterdruck hervorruft, wenn sie von Druckluft durchströmt wird.The
Jedenfalls kann auf diese Weise mittels nur eines einzigen Steuerventils 4 der Sonder-Steuereinheit 3b die Unterdruckversorgung von Arbeitskanälen gesteuert werden, die von unterschiedlichen Bestückungsplätzen 12 ausgehen.In any case, can be controlled in this way by means of only a
Eine besonders gute Performance lässt sich erzielen, wenn gleichzeitig zwei Vakuumerzeugereinrichtungen 34 über ein einziges Steuerventil 4 betrieben werden, wobei gleichzeitig über zwei Bestückungsplätze 12 hinweg eine Vakuumabgabe möglich ist.A particularly good performance can be achieved if two
Bei dem Ausführungsbeispiel der
Auf diese Weise lässt sich eine insbesondere bei Pressen genutzte Sicherheitsschaltung realisieren, die dem einen Arbeitskanal 15d nur dann Druckmedium zuführt, wenn beide Steuerventile 4 aktiviert sind. Somit können unkontrollierte Arbeitshübe einer Presse oder einer sonstigen Maschine verhindert werden.In this way, it is possible to realize a safety circuit, which is used in particular for presses, and which only supplies pressure medium to one working
Zwar lassen sich gerade die beschriebenen Schaltungen in Verbindung mit den Sonder-Steuereinheiten 3b besonders vorteilhaft verwenden. Gleichwohl ist die Erläuterung dieser Schaltungen exemplarisch zu verstehen und es können ohne weiteres auch andere Arten von Schaltungen realisiert werden.Although the circuits described in connection with the special control units 3b can be used particularly advantageously. However, the explanation of these circuits is to be understood by way of example and other types of circuits can be readily realized.
Da die Steuerventile 4 bevorzugt vom elektrisch betätigbaren Typ sind, empfiehlt sich die Übermittlung der für sie vorgesehenen elektrischen Steuersignale mittels einer im Innern des Ventilträgers 2 verlaufenden elektrischen Signalübertragungseinrichtung 35. Selbige ist in der Zeichnung nur schematisch angedeutet und erstreckt sich insbesondere in einem den Ventilträger 2 in der Reihenrichtung 8 durchsetzenden Signalübermittlungskanal 36. An jedem Bestückungsplatz 12 ist eine mit der Signalübertragungseinrichtung 35 verbundene elektrische Schnittstelle vorgesehen, die über die angebaute Zwischenplatte 23, 34 durchsetzende elektrische Leiter mit dem von der Zwischenplatte 23, 24 getragenen Antriebsteil 6 des mindestens einen Steuerventils 4 verbunden ist. Bei einer Standard-Steuereinheit 3a ohne Zwischenplatte 23 können die Antriebsteile 6 direkt mit der elektrischen Schnittstelle verbunden werden. Bei 37 sind im Bereich der Bestückungsplätze 12 vorgesehene Durchbrechungen des Ventilträgers 2 ersichtlich, durch die hindurch die elektrische Verbindung zwischen der Signalübertragungseinrichtung 35 und der jeweils zugeordneten Steuereinheit 3 stattfinden kann.Since the
Die elektrischen Steuersignale könnten abweichend vom Ausführungsbeispiel auch ohne Verwendung des Ventilträgers 2 zugeführt werden, z.B. über einzelne Kabel.Deviating from the embodiment, the electrical control signals could also be supplied without using the
Die beispielhafte Ventileinrichtung ermöglicht einen modularen Ausbau. Die elektrischen Anschlüsse wie auch die fluidischen Anschlüsse können über den Ventilträger 2 vorgenommen werden. Innerhalb einer Sonder-Steuereinheit 3b werden quasi wenigstens zwei ansonsten zur Einzelbestückung mit Standard-Steuereinheiten 3a nutzbare Bestückungsplätze 12 nach Art einer Höhenverkettung zusammengefasst, ohne dass auf externe Schlauchverbindungen zurückgegriffen werden müsste. Abgesehen von der Sonder-Steuereinheit 3b kann die Ventileinrichtung konventionell ausgestattet sein, es bedarf insbesondere keiner Modifikationen an den eventuell verwendeten Standard-Steuereinheiten 3a.The exemplary valve device allows a modular expansion. The electrical connections as well as the fluidic connections can be made via the
Ohne weiteres kann man wenigstens zwei Verbraucher-Anschlussöffnungen 16 zusammenschalten, um einen erhöhten Durchfluss zu erzielen. Zu erwähnen ist schließlich auch noch, dass insbesondere bei einer Ausstattung mit nur einem Steuerventil 4 neben diesem Steuerventil 4 platzsparend eine Sensoreinrichtung untergebracht werden kann, die den Betrieb des Steuerventils 4 überwacht und/oder die - wenn sie mit einem Drucksensor oder Druckschalter ausgestattet ist - eine Drucküberwachung vornehmen kann.It is readily possible to interconnect at least two
Die Zwischenplatten-Kanalanordnung 28 hat nicht notwendigerweise mit sämtlichen an den von der Zwischenplatte 24 der Sonder-Steuereinheit 3b überdeckten Bestückungsplätzen 12 ausmündenden Ventilträgerkanälen 15 zu kommunizieren. Die Mündungen nicht benötigter Ventilträgerkanäle 15 können durch die Zwischenplatte 24 einfach dicht abgedeckt werden, wie dies in
