Der Ventilträger ist mit einer internen elektrischen Signalübertragungseinrichtung ausgestattet, über die den einzelnen elektrisch betätigbaren Mehrwegeventilen ihre Betätigungssignale zugeführt werden können. Die ersten elektrischen Schnittstelleneinrichtungen gehören zu dieser internen elektrischen Signalübertragungseinrichtung und können mit einer an der Ventil-Grundfläche des jeweiligen Mehrwegeventils angeordneten elektrischen Schnittstelleneinrichtung elektrisch kontaktiert werden. Bei einer solchen Ventileinrichtung können die Mehrwegeventile stets nur über die interne elektrische Signalübertragungseinrichtung angesteuert werden. Eine individuelle Ansteuerung ist hier nicht möglich.Known valve devices of the type mentioned are designed according to ISO 5599-2, their structure as in the EP 1 081 389 B1 described, but with the difference that the arranged on the valve carrier first electrical interface devices according to standards protrude a piece far beyond the mounting surface. The valve carrier is equipped with an internal electrical signal transmission device via which the individual electrically actuated multi-way valves their operating signals can be supplied. The first electrical Interface devices belong to this internal electrical signal transmission device and can be electrically contacted with an electrical interface device arranged on the valve base of the respective multiway valve. In such a valve device, the multiway valves can always be controlled only via the internal electrical signal transmission device. An individual control is not possible here.

Die DE 44 44 024 A1 beschreibt eine Ventileinrichtung, bei der die einzelnen Mehrwegeventile mit einer elektrischen Schnittstelleneinrichtung ausgestattet sind, die abseits der Ventil-Grundfläche platziert ist. Jedes Mehrwegeventil wird hier individuell über eine solche elektrische Schnittstelleneinrichtung angesteuert. Der Ventilträger ist von einem einfachen Fluidverteiler gebildet, der keine elektrische Signalübertragungseinrichtung beinhaltet.The DE 44 44 024 A1 describes a valve device in which the individual multi-way valves are equipped with an electrical interface device, which is placed away from the valve base.

Aus dem Patent Abstracts of Japan zur JP 2002/039418 A ist ein Magnetventilverteiler bekannt, bei dem an einem Verteilerblock mehrere Magnetventile montiert sind, die über elektrische Schnittstelleneinrichtungen mit einer Hauptstromversorgung des Verteilerblocks verbunden sind. Eine zusätzliche elektrische Schnittstelleneinrichtung an jedem Magnetventil ermöglicht den alternativen Anschluss einer externen Stromversorgung. Da alle Magnetventile eine elektrische Schnittstelleneinrichtung für die Hauptstromversorgung aufweisen, sind zusätzliche mechanische Umschaltmittel erforderlich, die die Verbindung zu der Hauptstromversorgung unterbrechen, wenn die externe Stromversorgung angeschlossen wird.From the Patent Abstracts of Japan to JP 2002/039418 A a solenoid valve manifold is known in which a plurality of solenoid valves are mounted on a manifold block, which are connected via electrical interface means to a main power supply of the manifold block. An additional electrical interface device on each solenoid valve allows alternative connection of an external power supply. Since all the solenoid valves have an electrical interface device for the main power supply, additional mechanical switching means are required, which interrupt the connection to the main power supply when the external power supply is connected.

By a switching element can be switched between the two types of connection.

Es ist die Aufgabe der vorliegenden Erfindung, Maßnahmen vorzuschlagen, die eine flexible Ansteuerung von zur Montage an einem Ventilträger ausgebildeten, elektrisch betätigbaren Mehrwegeventilen ermöglichen.It is the object of the present invention to propose measures that allow a flexible control of designed for mounting on a valve carrier, electrically actuated multi-way valves.

Zur Lösung dieser Aufgabe ist in Verbindung mit einer Ventileinrichtung der eingangs genannten Art vorgesehen, dass die zweite elektrische Schnittstelleneinrichtung für von der internen elektrischen Signalübertragungseinrichtung unabhängige Signalübertragung ausgelegt und abseits der Ventil-Grundfläche am Mehrwegeventil angeordnet ist, und dass in dem der ersten elektrischen Schnittstelleneinrichtung gegenüberliegenden Bereich der Ventil-Grundfläche bei mindestens einem Mehrwegeventil eine mit der ersten elektrischen Schnittstelleneinrichtung elektrisch kontaktierbare dritte elektrische Schnittstelleneinrichtung und bei mindestens einem weiteren Mehrwegeventil eine keine elektrischen Schnittstellenmittel enthaltende nichtelektrische Aufnahme für den über die Bestückungsfläche vorstehenden Abschnitt der ersten elektrischen Schnittstelleneinrichtung angeordnet ist.To achieve this object is provided in connection with a valve device of the type mentioned that the second electrical interface device is designed for independent of the internal electrical signal transmission device signal transmission and located away from the valve base on the multi-way valve, and that in the first electrical interface device opposite In at least one multi-way valve, a third electrical interface device can be electrically contacted to at least one multiway valve, and a nonelectrical receptacle containing no electrical interface means is arranged for at least one further multiway valve for the section of the first electrical interface device projecting beyond the mounting surface.

Auf diese Weise kann mindestens ein elektrisch betätigbares Mehrwegeventil zusätzlich zu einer die Verbindung mit der internen elektrischen Signalübertragungseinrichtung des Ventilträgers ermöglichenden (dritten) elektrischen Schnittstelleneinrichtung eine weitere (zweite) elektrische Schnittstelleneinrichtung aufweisen, die eine von der internen elektrischen Signalübertragungseinrichtung des Ventilträgers unabhängige Signalübertragung gestattet. Diese zweite elektrische Signalübertragungseinrichtung ist abseits der Ventil-Grundfläche am Mehrwegeventil angeordnet, so dass sie bei am Ventilträger installiertem Mehrwegeventil für die erforderlichen Anschlussmaßnahmen zugänglich bleibt. Der Anwender hat somit die Möglichkeit, ein oder mehrere Mehrwegeventile einer Ventileinrichtung sowohl über die interne elektrische Signalübertragungseinrichtung als auch unabhängig davon, individuell anzusteuern. Bei entsprechender interner Verschaltung besteht auch die Möglichkeit, die beiden Signalübertragungseinrichtungen nicht nur alternativ zu nutzen, sondern auch gleichzeitig, um beispielsweise gewisse Logikfunktionen auszuführen. Ist von, vornherein klar, dass man bezüglich eines Mehrwegeventils auf einen Signaltransfer über die interne elektrische Signalübertragungseinrichtung verzichten will, kann man auf ein Mehrwegeventil zurückgreifen, das für die elektrische Ansteuerung über lediglich die zweite elektrische Schnittstelleneinrichtung verfügt, wobei die Kompatibilität mit der Norm ISO 5599-2 durch eine gegenüberliegend der ersten Schnittstelleneinrichtung des Ventilträgers an der Ventil-Grundfläche vorgesehene Aufnahme gewährleistet ist, in die der über die Bestückungsfläche vorstehende Abschnitt der ersten Schnittstelleneinrichtung eintauchen kann. Diese Aufnahme ist nichtelektrisch, sie enthält also keine mit der ersten elektrischen Schnittstelleneinrichtung kontaktierbare elektrische Schnittstellenmittel, so dass das Mehrwegeventil sehr kostengünstig herstellbar ist.In this way, in addition to a (third) electrical interface device enabling the connection to the internal electrical signal transmission device of the valve carrier, at least one electrically actuatable multiway valve device can have a further (second) electrical interface device which permits signal transmission independent of the internal electrical signal transmission device of the valve carrier. This second electrical signal transmission device is off the valve base on Multi-way valve arranged so that it remains accessible to the valve support installed multi-way valve for the required follow-up measures. The user thus has the option of individually or individually controlling one or more multiway valves of a valve device both via the internal electrical signal transmission device and independently thereof. With a corresponding internal interconnection, it is also possible to use the two signal transmission devices not only as an alternative, but also at the same time, for example to carry out certain logic functions. If, from the outset, it is clear that one wishes to dispense with a signal transfer via the internal electrical signal transmission device with respect to a multiway valve, one can resort to a multiway valve which has only the second electrical interface device for the electrical control, the compatibility with the standard ISO 5599 -2 is ensured by an opening provided opposite the first interface device of the valve carrier on the valve base, into which the portion of the first interface device protruding beyond the component surface can dip. This receptacle is non-electric, so it contains no contact with the first electrical interface device electrical interface means, so that the multi-way valve is very inexpensive to produce.

Innerhalb einer Ventileinrichtung, deren Ventilträger über mehrere Bestückungsplätze verfügt, können gleichzeitig Mehrwegeventile unterschiedlichen Typs enthalten sein, also entweder solche mit einer zweiten und einer dritten elektrischen Schnittstelleneinrichtung oder auch solche mit lediglich einer zweiten Schnittstelleneinrichtung, wobei aber auch eine Kombination mit konventionellen Mehrwegeventilen gewährleistet ist, die lediglich eine mit der ersten elektrischen Schnittstelleneinrichtung kontaktierbare Schnittstelleneinrichtung an der Ventil-Grundfläche aufweisen. Die Möglichkeit zu einem beliebigen Ventilmix schafft eine hohe Variabilität bei der Ausstattung der Ventileinrichtung.Within a valve device whose valve carrier has a plurality of placement stations, multiway valves of different types can be contained simultaneously, ie either those with a second and a third electrical interface device or even those with only a second interface device, but also ensures a combination with conventional multi-way valves is that have only one contactable with the first electrical interface device interface device on the valve base. The possibility of any combination of valves creates a high variability in the equipment of the valve device.

Vorteilhafte Weiterbildungen der Erfindung gehen aus den Unteransprüchen hervor.Advantageous developments of the invention will become apparent from the dependent claims.

Bei den ersten und/oder zweiten und/oder dritten elektrischen Schnittstelleneinrichtungen handelt es sich insbesondere um Steckvorrichtungen.The first and / or second and / or third electrical interface devices are, in particular, plug-in devices.

Die interne elektrische Signalübertragungseinrichtung kann ohne weiteres über einzelne flexible elektrische Leiter verfügen, die zu den am Ventilträger fest fixierten ersten elektrischen Schnittstelleneinrichtungen führen. Möglich ist aber auch ein interner elektrischer Bus.The internal electrical signal transmission device can readily have individual flexible electrical conductors leading to the first electrical interface devices firmly fixed to the valve carrier. But it is also possible an internal electric bus.

Bevorzugt enthält die interne elektrische Signalübertragungseinrichtung eine die vorhandenen ersten elektrischen Schnittstelleneinrichtungen tragende Signalverteilerplatte, die sich in einem den Ventilträger durchziehenden Signalverteilerkanal befindet und die auch die ersten elektrischen Schnittstelleneinrichtungen trägt, die jeweils durch eine Wanddurchbrechung hindurch über die Bestückungsfläche vorstehen können. Insbesondere in Verbindung mit einem in Längsrichtung segmentierten Ventilträger kann auch die Signalverteilerplatte in Längsrichtung segmentiert und mit variabler Länge zusammengesetzt sein.The internal electrical signal transmission device preferably contains a signal distributor plate which carries the existing first electrical interface devices and which is located in a signal distributor channel passing through the valve carrier and which also carries the first electrical interface devices, which can each protrude through the component surface through a wall opening. In particular, in conjunction with a longitudinally segmented valve carrier and the signal distribution plate can be segmented in the longitudinal direction and composed of variable length.

Als Anbringungsort für die zweite elektrisch Schnittstelleneinrichtung empfiehlt sich insbesondere die der Ventil-Grundfläche entgegengesetzte Ventil-Oberseite des Mehrwegeventils. Eine stirnseitige Anordnung wäre jedoch ebenfalls denkbar.As a mounting location for the second electrically interface device, in particular, the valve top surface opposite valve top of the multi-way valve is recommended. However, a frontal arrangement would also be conceivable.

Auch wenn das Mehrwegeventil anstelle einer dritten elektrischen Schnittstelleneinrichtung eine nichtelektrische Aufnahme für die zweite elektrische Schnittstelleneinrichtung aufweist, empfiehlt es sich, an der Ventil-Grundfläche eine Dichtung vorzusehen, die bei montiertem Mehrwegeventil mit der Bestückungsfläche in Dichtkontakt steht und ein Eindringen von Verunreinigungen oder von Feuchtigkeit in die erste elektrische Schnittstelleneinrichtung bzw. die zugeordnete Signalübertragungseinrichtung verhindert.Even if the multi-way valve has a non-electrical receptacle for the second electrical interface device instead of a third electrical interface device, it is advisable to provide a seal on the valve base which is in sealed contact with the mounting surface when the multi-way valve is mounted and if contaminants or moisture are permeated prevented in the first electrical interface device or the associated signal transmission device.

Besonders einfach lässt sich die nichtelektrische Aufnahme als einfache Gehäusevertiefung des Mehrwegeventils realisieren.The non-electric recording can be implemented particularly simply as a simple housing depression of the multi-way valve.

Es ist ferner zweckmäßig, wenn sich die dritte elektrische Schnittstelleneinrichtung oder die alternativ vorgesehene nichtelektrische Aufnahme gemeinsam mit der zweiten elektrischen Schnittstelleneinrichtung an der elektrischen Antriebseinrichtung des Mehrwegeventils befinden, welche letztere insbesondere Bestandteil einer elektrofluidischen Vorsteuerstufe ist.It is also expedient if the third electrical interface device or the alternatively provided non-electrical receptacle are located together with the second electrical interface device on the electric drive device of the multi-way valve, which latter is in particular part of an electro-fluidic pilot stage.

Bei allen Ausführungsformen kann insbesondere die zweite elektrische Schnittstelleneinrichtung nicht nur für das Einspeisen von Betätigungssignalen ausgelegt sein, sondern auch für die Ausgabe von Sensorsignalen, die einen Betriebszustand des zugeordneten Mehrwegeventils betreffen.In all embodiments, in particular, the second electrical interface device may be designed not only for the supply of actuation signals, but also for the output of sensor signals, which relate to an operating state of the associated multi-way valve.

Nachfolgend wird die Erfindung anhand der beiliegenden Zeichnung näher erläutert. In dieser zeigen:

Die in ihrer Gesamtheit mit Bezugsziffer 1 bezeichnete Ventileinrichtung ist als Ventilbatterie konzipiert und enthält einen Ventilträger 2, der gleichzeitig mit einer Mehrzahl von elektrisch betätigbaren Mehrwegeventilen 3 lösbar bestückbar ist. Die Figur 1 zeigt den fertig bestückten Zustand.The designated in its entirety by reference numeral 1 valve device is designed as a valve battery and includes a valve carrier 2, which is simultaneously releasably equipped with a plurality of electrically actuated multi-way valves 3. The FIG. 1 shows the ready equipped state.

Die Außenfläche des Ventilträgers 2 bildet eine in Figur 1 von den Mehrwegeventilen 3 abgedeckte Bestückungsfläche 4, an die die Mehrwegeventile 3 anbaubar sind. Die Bestückungsfläche 4 ist hierbei in mehrere in Richtung einer Ventilträger-Hauptachse 5 aufeinanderfolgende Bestückungsplätze 6 unterteilt, die jeweils für die Installation eines Mehrwegeventils 3 ausgelegt sind.The outer surface of the valve carrier 2 forms an in FIG. 1 covered by the multi-way valves 3 mounting surface 4, to which the multi-way valves 3 are attachable. The assembly area 4 is in this case subdivided into a plurality of successive placement spaces 6 in the direction of a valve carrier main axis 5, each of which is designed for the installation of a multiway valve 3.

Der Ventilträger 2 ist von einer Mehrzahl fluidischer Ventilträgerkanäle 7 durchzogen. Darunter befindet sich mindestens ein mit einer externen Druckquelle P verbindbarer Speisekanal 7a und mindestens ein mit einer Drucksenke R, S - insbesondere die Atmosphäre - verbindbarer Abführkanal 7b, 7c. Diese Kanäle erstrecken sich im Innern des Ventilträgers 2 in Richtung der Ventilträger-Hauptachse 5, wobei sie jeweils gleichzeitig zu sämtlichen Bestückungsplätzen 6 ausmünden. Die entsprechenden Mündungen sind in Figur 1 bei einem Bestückungsplatz 6 mit Bezugsziffern 8 angedeutet.The valve carrier 2 is traversed by a plurality of fluidic valve carrier channels 7. Below is at least one connectable to an external pressure source P feed channel 7a and at least one with a pressure sink R, S - in particular the atmosphere - connectable discharge channel 7b, 7c. These channels extend in the interior of the valve carrier 2 in the direction of the valve carrier main axis 5, wherein they each open simultaneously to all placement spaces 6. The corresponding mouths are in FIG. 1 indicated at a placement place 6 with reference numerals 8.

Unter den Ventilträgerkanälen 7 befinden sich außerdem Arbeitskanäle 7d, 7e. Diese sind den Bestückungsplätzen 6 individuell zugeordnet. Exemplarisch münden an jedem Bestückungsplatz 6 zwei Arbeitskanäle 7d, 7e aus, die andernends zu einer abseits der Bestückungsfläche 4 liegenden Verbraucheranschlussfläche 12 an der Außenfläche des Ventilträgers 2 ausmünden. Im Bereich der Verbraucheranschlussfläche 12 können an die Arbeitskanäle 7d, 7e zu betätigende Verbraucher angeschlossen werden, beispielsweise mittels Fluidkraft betriebene Antriebe. Der Anschluss kann über nicht gezeigte Fluidleitungen vorgenommen werden.Under the valve carrier channels 7 are also working channels 7d, 7e. These are assigned to the placement places 6 individually. By way of example, two working channels 7d, 7e terminate at each placement location 6, which at the other end open out to a consumer connection surface 12 lying on the outer surface of the valve carrier 2 away from the assembly surface 4. In the area of the consumer connection surface 12, consumers to be actuated can be connected to the working channels 7d, 7e, for example by means of drives operated by fluid power. The connection can be made via fluid lines, not shown.

Die an den Bestückungsflächen 4 vorhandenen Kanalmündungen der Arbeitskanäle 7d, 7c sind in Figur 1 bei einem Bestückungsplatz 6 angedeutet und mit Bezugsziffer 9 identifiziert.The existing at the mounting surfaces 4 channel mouths of the working channels 7d, 7c are in FIG. 1 indicated at a placement place 6 and identified by reference numeral 9.

An sämtlichen Bestückungsplätzen 6 befinden sich identische Mündungsmuster an Kanalmündungen 8, 9. Die Mündungsmuster können insbesondere der Norm ISO 5599-2 entsprechen.Identical orifice patterns at channel openings 8, 9 are located at all placement locations 6. The orifice patterns can correspond in particular to the standard ISO 5599-2.

Ebenfalls längs der Ventilträger-Hauptachse 5 erstreckt sich im Ventilträger 2 ein als Signalverteilerkanal 13 bezeichneter Hohlraum. In ihm verläuft eine Signalverteilerplatte 14, die eine Vielzahl elektrischer Leiter 15 trägt und die Bestandteil einer internen elektrischen Signalübertragungseinrichtung 16 des Ventilträgers 2 ist. Über diese interne Signalübertragungseinrichtung 16 können elektrische Betätigungssignale an die elektrische Antriebseinrichtung 17 der einzelnen Mehrwegeventile 3 übermittelt werden. Eingespeist werden die Betätigungssignale bevorzugt über eine von außen her zugängliche, am Ventilträger 2 installierte zentrale elektrische Schnittstelleneinrichtung, die in der Zeichnung nicht weiter abgebildet ist. Die Signaleinspeisung erfolgt typabhängig entweder seriell oder parallel. Die Signalübertragungseinrichtung 16 kann bei Bedarf über Elektronikkomponenten verfügen, die die Betätigungssignale verarbeiten und an die gewünschte Ventiladresse weiterleiten können.Also along the valve carrier main axis 5 extends in the valve carrier 2 as a signal distribution channel 13 designated cavity. In it runs a signal distribution plate 14 which carries a plurality of electrical conductors 15 and which is part of an internal electrical signal transmission device 16 of the valve carrier 2. Via this internal signal transmission device 16, electrical actuating signals can be transmitted to the electric drive device 17 of the individual multiway valves 3. The actuating signals are preferably supplied via an externally accessible, installed on the valve carrier 2 central electrical interface device, which is not shown in the drawing. The signal input is type-dependent either serial or parallel. If required, the signal transmission device 16 can have electronic components which can process the actuating signals and forward them to the desired valve address.

Für die Verbindung mit den elektrischen Antriebseinrichtungen 17 beinhaltet die interne Signalübertragungseinrichtung 16 pro Bestückungsplatz 6 eine erste elektrisch Schnittstelleneinrichtung 22. Sie ist besonders gut in Figuren 3 und 5 zu erkennen. Exemplarisch sind die ersten elektrischen Schnittstelleneinrichtungen 22 an der Signalverteilerplatte 14 angeordnet und werden von dieser getragen.For the connection to the electrical drive devices 17, the internal signal transmission device 16 per placement place 6 contains a first electrically interface device 22. It is particularly well in Figures 3 and 5 to recognize. By way of example, the first electrical interface devices 22 are arranged on the signal distribution plate 14 and are supported by the latter.

An jedem Bestückungsplatz 6 mündet eine den Ventilträger 2 durchsetzende Wanddurchbrechung 25 aus, die andererseits in den Signalverteilerkanal 13 mündet. Jede erste elektrische Schnittstelleneinrichtung 22 greift vom Signalverteilerkanal 13 her durch die ihr zugeordnete Wanddurchbrechung 25 hindurch und ragt ein Stück weit, mit einem in Figuren 3 und 5 bei "a" kenntlich gemachten Überstand, über die Bestückungsfläche 4 vor. Ansonsten ist die Bestückungsfläche 4 zumindest im Wesentlichen eben.At each placement space 6 opens a valve carrier 2 passing through the wall opening 25, which on the other hand opens into the signal distribution channel 13. Each first electrical interface device 22 is engaged by the signal distribution channel 13 ago through her assigned wall opening 25 through and protrudes a piece, with a in Figures 3 and 5 supernatant indicated at "a" above the placement area 4. Otherwise, the mounting surface 4 is at least substantially planar.

Zweckmäßigerweise sind die ersten elektrischen Schnittstelleneinrichtungen 22 als Steckvorrichtungen ausgeführt. Sie enthalten beispielsweise ein aus Kunststoffmaterial bestehendes Steckvorrichtungsgehäuse 26 mit mehreren darin angeordneten und mit den elektrischen Leitern 15 verbundenen Steckkontakten 27a.Conveniently, the first electrical interface devices 22 are designed as plug-in devices. They contain, for example, a plug-in device housing 26 made of plastic material with a plurality of plug contacts 27a arranged therein and connected to the electrical conductors 15.

Der Ventilträger 2 kann aus Kunststoffmaterial bestehen, ist vorzugsweise jedoch ein Metallteil, insbesondere ein Aluminiumkörper. Bevorzugt ist er in mehrere in Richtung der Ventilträger-Hauptachse 5 aneinander gesetzte Ventilträgersegmente 27 unterteilt, die in variabler Anzahl miteinander kombinierbar sind, um einen Ventilträger 2 variabler Länge zu erhalten. Jedes Ventilträgersegment 27 enthält mindestens einen Bestückungsplatz 6.The valve carrier 2 may consist of plastic material, but is preferably a metal part, in particular an aluminum body. It is preferably subdivided into a plurality of valve carrier segments 27 set against one another in the direction of the main valve carrier axis 5, which can be combined with one another in a variable number in order to obtain a variable length valve carrier 2. Each valve carrier segment 27 contains at least one placement space 6.

In entsprechender Weise kann auch die Signalverteilerplatte 14 in Längsrichtung segmentiert sein, wobei zwischen den einzelnen Plattensegmenten lösbare elektrische Verbindungen herstellbar sind. Somit kann die Länge der Signalverteilerplatte 14 modular an die Länge des momentan gewählten Ventilträgers 2 angepasst werden. Alternativ wäre jedoch auch eine auf das Längenmaß des jeweiligen Ventilträgers 2 abgestimmte Baulänge einer einteiligen Signalverteilerplatte 14 möglich.In a corresponding manner, the signal distribution plate 14 may be segmented in the longitudinal direction, wherein detachable electrical connections can be produced between the individual plate segments. Thus, the length of the signal distribution plate 14 can be modularly adapted to the length of the currently selected valve carrier 2. Alternatively, however, a length matched to the length of the respective valve carrier 2 length of a one-piece signal distribution plate 14 would be possible.

Bei einer nicht dargestellten Variante sind die ersten elektrischen Schnittstelleneinrichtungen 22 direkt am Ventilträger 2 fixiert und über individuell von ihnen abgehende flexible elektrische Leiter, beispielsweise einzelne Kabel, an die weiter oben erwähnte zentrale elektrische Schnittstelleneinrichtung angeschlossen.In a variant, not shown, the first electrical interface means 22 are fixed directly to the valve carrier 2 and individually via them outgoing flexible electrical conductors, such as individual cables, connected to the above-mentioned central electrical interface device.

Sämtliche Mehrwegeventile 3 besitzen an ihrer Unterseite eine Ventil-Grundfläche 28, mit der sie an die Bestückungsfläche 4 ansetzbar sind. Die Befestigung im angebauten Zustand erfolgt beispielhaft mittels Schraubverbindungen 32. Andere, bevorzugt ebenfalls lösbare Verbindungsarten sind ebenfalls denkbar.All multiway valves 3 have on their underside a valve base 28, with which they can be attached to the mounting surface 4. The attachment in the mounted state is done by way of example by means of screw 32. Other, preferably also releasable connection types are also conceivable.

Jedes Mehrwegeventil 3 enthält ein mit der elektrischen Antriebseinrichtung 17 zu einer Baueinheit zusammengefasstes blockförmiges Steuerteil 33. Darin befindet sich ein lediglich in Figur 2 schematisch angedeutetes, bevorzugt schieberartiges bewegliches Ventilglied 34, das unterschiedlich positionierbar ist, um in an sich bekannter Weise in dem Steuerteil 33 verlaufende Ventilkanäle 35 wunschgemäß miteinander zu verschalten. Diese Ventilkanäle 35 münden mit einer den Kanalmündungen 8, 9 entsprechenden Verteilung zu der Ventil-Grundfläche 28 aus, so dass sich bei angebautem Mehrwegeventil 3 eine zuordnungsrichtige Verbindung zwischen den Ventilkanälen 35 und den Ventilträgerkanälen 7 einstellt. Nicht näher gezeigte Dichtungsmittel sorgen für einen leckagefreien Fluidübertritt.Each multi-way valve 3 contains a combined with the electric drive means 17 to form a unit block-shaped control part 33. Darin is a purely in FIG. 2 schematically indicated, preferably slide-like movable valve member 34 which is positioned differently to connect in a conventional manner in the control part 33 extending valve channels 35 as desired with each other. These valve channels 35 open with a distribution corresponding to the channel openings 8, 9 to the valve base 28, so that adjusts a multi-way valve 3 a correct assignment connection between the valve channels 35 and the valve carrier channels 7. Sealant not shown in detail provide a leak-free fluid transfer.

Die elektrische Antriebseinrichtung 17 ist aufgrund ihr zugeführter elektrischer Betätigungssignale in der Lage, die Stellung des Ventilgliedes 34 vorzugeben. Bei einem direkt betätigten Mehrwegeventil 3 kooperiert die Antriebseinrichtung 17 direkt elektromechanisch mit dem Ventilglied 34. In der Regel wird jedoch eine vorgesteuerte Bauform des Mehrwegeventils 3 vorgezogen, bei der die das Ventilglied 34 umschaltende Betätigungskraft eine Fluidkraft ist, deren Auferlegung durch eine elektrische Antriebseinrichtung 17 erfolgt, die Bestandteil einer elektrofluidischen Vorsteuerstufe 36 ist. Diese wandelt die eingehenden elektrischen Betätigungssignale in fluidische Steuersignale für die Aktivierung des Ventilgliedes 34 um.The electric drive device 17 is due to its supplied electrical actuation signals in a position to specify the position of the valve member 34. In a directly operated multi-way valve 3, the drive means 17 cooperates directly electromechanically with the valve member 34. However, a pilot-controlled design of the multi-way valve 3 is generally preferred in which the actuation force switching the valve member 34 is a fluid force whose imposition is performed by an electric drive device 17 which is part of an electro-fluid pilot stage 36. This converts the incoming electrical actuation signals into fluidic control signals for the activation of the valve member 34.

Exemplarisch ist eine solche Vorsteuerstufe 36 vorhanden, die je nach Bauform über ein oder zwei elektrisch betätigbare Vorsteuerventile verfügt, die zweckmäßigerweise zu einer Baugruppe zusammengefasst sind. Bevorzugt sind sie an eine Stirnseite des Steuerteils 33 angebaut, wobei sie innerhalb der Vorsteuerstufe 36 zu einer Baueinheit zusammengefasst sind. Es wäre jedoch auch möglich, die Vorsteuerventile der Vorsteuerstufe 36 an unterschiedlichen Stellen des Steuerteils 33 zu installieren.By way of example, such a pilot stage 36 is provided which, depending on the design, has one or two electrically actuable pilot valves, which are expediently combined to form an assembly. Preferably, they are mounted on an end face of the control part 33, wherein they are combined within the pilot stage 36 to form a structural unit. However, it would also be possible to install the pilot valves of the pilot stage 36 at different points of the control part 33.

Jedes erfindungsgemäße Mehrwegeventil 3 enthält eine abseits von der Ventil-Grundfläche 28 an frei zugänglicher Stelle angeordnete elektrische Schnittstelleneinrichtung, die zur besseren Unterscheidung als zweite elektrische Schnittstelleneinrichtung 23 bezeichnet sei. Diese ist mit den Antriebsmitteln 37 der elektrischen Antriebseinrichtung 17 elektrisch verbunden, was beispielhaft unter Zwischenschaltung einer im Innern der Antriebseinrichtung 17 platzierten Leiterplatte 38 geschieht. Vorzugsweise befindet sich die zweite elektrische Schnittstelleneinrichtung 23 an der der Ventil-Grundfläche 28 entgegengesetzten Ventil-Oberseite, wie dies beim Ausführungsbeispiel der Fall ist.Each multi-way valve 3 according to the invention contains an electrical interface device, which is arranged at a freely accessible location apart from the valve base 28 and is designated as a second electrical interface device 23 for better distinction. This is electrically connected to the drive means 37 of the electric drive device 17, which is done by way of example with the interposition of a printed circuit board 38 placed inside the drive device 17. Preferably, the second electrical interface device 23 is located on the valve base 28 opposite valve top, as is the case in the embodiment.

Die elektrischen Antriebsmittel 37 beinhalten beispielsweise eine Elektromagneteinrichtung oder eine Piezoeinrichtung.The electric drive means 37 include, for example, a solenoid device or a piezo device.

Über die zweite elektrische Schnittstelleneinrichtung 23, die vorzugsweise als Steckvorrichtung ausgebildet ist, kann das Mehrwegeventil 3 unabhängig von der internen Signalübertragungseinrichtung 16 mit Betätigungssignalen versorgt werden. Dies ermöglicht eine individuelle Ansteuerung des Mehrwegeventils 3 und mithin eine äußerst variable Betriebsweise der Ventileinrichtung 1.About the second electrical interface device 23, which is preferably designed as a plug-in device, the Multiway valve 3 are supplied independently of the internal signal transmission means 16 with actuating signals. This allows individual control of the multi-way valve 3 and thus an extremely variable operation of the valve device. 1

Beispielsweise kann an der zweiten elektrischen Schnittstelleneinrichtung 23 ein individuelles elektrisches Anschlussteil 38, insbesondere auch in Gestalt einer Steckvorrichtung, angeschlossen werden, von dem ein elektrisches Kabel 42 abgeht, so dass eine externe Einspeisung von Betätigungssignalen möglich ist.For example, at the second electrical interface device 23, an individual electrical connection part 38, in particular in the form of a plug-in device, are connected, from which an electrical cable 42 goes off, so that an external supply of actuation signals is possible.

Der Anschlussvorrichtungstyp der zweiten elektrischen Schnittstelleneinrichtung 23 kann sich von demjenigen der ersten elektrischen Schnittstelleneinrichtung 22 unterscheiden. Auf diese Weise kann man eine Signaleinspeisung über unterschiedlich genormte Steckvorrichtungen durchführen.The type of connector of the second electrical interface device 23 may be different from that of the first electrical interface device 22. In this way, you can perform a signal input via differently standardized plug devices.

Das aus den Figuren 2 und 3 hervorgehende erfindungsgemäße Mehrwegeventil 3 enthält zusätzlich eine weitere elektrische Schnittstelleneinrichtung, die der besseren Unterscheidung wegen als dritte elektrische Schnittstelleneinrichtung 24 bezeichnet sei. Diese befindet sich an der Ventil-Grundfläche 28, und zwar in demjenigen Bereich, der bei an den Ventilträger 2 angebautem Mehrwegeventil 3 der ventilträgerseitigen ersten elektrischen Schnittstelleneinrichtung 22 gegenüberliegt. Die Richtung des Gegenüberliegens verläuft hierbei rechtwinklig zur Bestückungsfläche 4.That from the Figures 2 and 3 Outstanding multi-way valve 3 according to the invention additionally contains a further electrical interface device which, for better distinction, is referred to as a third electrical interface device 24. This is located on the valve base 28, in that area, which is opposite to the valve carrier 2 mounted multi-way valve 3 of the valve carrier side first electrical interface device 22. The direction of the opposite runs at right angles to the mounting surface 4th

Indem die erste und dritte Schnittstelleneinrichtung 22, 24 komplementär zueinander ausgebildet sind, ergibt sich somit bei angebautem Mehrwegeventil 3 eine elektrische Verbindung zwischen der ersten und dritten Schnittstelleneinrichtung 22, 24, so dass auch auf diesem Wege der elektrischen Antriebseinrichtung 17 Betätigungssignale zugeführt werden können. Auch die dritte elektrische Schnittstelleneinrichtung 24 ist mit den Antriebsmitteln 37 der elektrischen Antriebseinrichtung 17 kontaktiert.By virtue of the fact that the first and third interface devices 22, 24 are designed to be complementary to one another, an electrical connection between the first and third interface device 22 results when the multi-way valve 3 is attached. 24, so that also in this way the electric drive means 17 actuating signals can be supplied. The third electrical interface device 24 is also contacted with the drive means 37 of the electric drive device 17.

Das Herstellen und Lösen der elektrischen Verbindung zwischen der ersten und dritten elektrischen Schnittstelleneinrichtung 22, 24 findet automatisch beim Ansetzen bzw. Abnehmen des Mehrwegeventils 3 an die bzw. von der Bestückungsfläche 4 statt. Die dritte elektrische Schnittstelleneinrichtung 24 ist daher beim Ausführungsbeispiel ebenfalls eine Steckvorrichtung. Die elektrische Verbindung könnte allerdings auch ausschließlich auf der Basis eines kraftschlüssigen Berührkontaktes ohne gegenseitigen Eingriff hergestellt werden.The establishment and release of the electrical connection between the first and third electrical interface device 22, 24 takes place automatically when applying or removing the multi-way valve 3 to or from the mounting surface 4. The third electrical interface device 24 is therefore also a plug-in device in the embodiment. However, the electrical connection could also be made exclusively on the basis of a frictional Berührkontaktes without mutual interference.

Bei dem derart mit zwei elektrischen Schnittstelleneinrichtungen 22, 24 ausgestatteten Mehrwegeventil 3 kann die Ansteuerung entweder nur über die interne Signalübertragungseinrichtung 16 oder nur individuell, von extern her, mittels der zweiten elektrischen Schnittstelleneinrichtung 23 stattfinden, oder aber es ist eine gleichzeitige Ansteuerung über diese beiden Signalwege möglich. Letzteres gestattet unter anderem auch die Realisierung logischer Verschaltungen, bei denen gewisse Schaltungsergebnisse nur auftreten, wenn über die zweite und dritte elektrische Schnittstelleneinrichtung 23, 24 in besonderer Weise aufeinander abgestimmte Betätigungssignale eingehen.In the multi-way valve 3 thus equipped with two electrical interface devices 22, 24, the control can take place either only via the internal signal transmission device 16 or only individually, externally, by means of the second electrical interface device 23, or it is a simultaneous control via these two signal paths possible. The latter allows, among other things, the realization of logic interconnections in which certain circuit results only occur if received via the second and third electrical interface means 23, 24 in a special way coordinated operating signals.

Bei der aus Figuren 4 und 5 ersichtlichen alternativen Bauform des erfindungsgemäßen Mehrwegeventils 3 befindet sich an besagter Stelle der Ventil-Grundfläche 28 anstelle einer dritten elektrischen Schnittstelleneinrichtung 24 eine bevorzugt als einfache Gehäusevertiefung des Mehrwegeventils 3 konzipierte nichtelektrische Aufnahme 43, deren rechtwinkelig zur Bestückungsfläche 4 gemessene Tiefe mindestens dem Überstand "a" der ersten elektrischen Schnittstelleneinrichtung 22 entspricht, so dass der über die Bestückungsfläche 4 überstehende Abschnitt der ersten elektrischen Schnittstelleneinrichtung 22 bei an den Ventilträger 2 angebautem Mehrwegeventil 3 in die nichtelektrische Aufnahme 43 ungehindert eintauchen kann. Dadurch ist ein vollflächiges Anliegen des Mehrwegeventils 3 an die Bestückungsfläche 4 gewährleistet, obwohl die erste elektrische Schnittstelleneinrichtung 22 über die Bestückungsfläche 4 vorsteht.At the FIGS. 4 and 5 apparent alternative design of the multi-way valve 3 according to the invention is located at said location of the valve base 28 instead of a third electrical interface means 24 a preferably as a simple housing recess of the multi-way valve. 3 designed non-electric recording 43, the measured perpendicular to the mounting surface 4 depth at least the supernatant "a" of the first electrical interface device 22, so that the protruding over the mounting surface 4 section of the first electrical interface device 22 when mounted on the valve support 2 multi-way valve 3 in the non-electric Recording 43 can dip freely. Thereby, a full-surface concerns of the multi-way valve 3 is ensured to the mounting surface 4, although the first electrical interface device 22 projects beyond the mounting surface 4.

Somit ist die Installation eines Mehrwegeventils 3 möglich, das ausschließlich für eine individuelle, externe Ansteuerung ausgelegt ist und für diesen Zweck über die schon erwähnte zweite elektrische Schnittstelleneinrichtung 23 verfügt. Da diese nicht an der Ventil-Grundfläche 28 angeordnet ist, bleibt sie für die gewünschten Anschlussmaßnahmen auch dann noch frei zugänglich, wenn das Mehrwegeventil 3 am Ventilträger 2 installiert ist.Thus, the installation of a multi-way valve 3 is possible, which is designed exclusively for an individual, external control and for this purpose has the already mentioned second electrical interface device 23. Since this is not arranged on the valve base 28, it still remains freely accessible for the desired connection measures when the multi-way valve 3 is installed on the valve carrier 2.

Innerhalb der nichtelektrischen Aufnahme 43 befinden sich keine elektrischen Kontakte, die eine elektrische Verbindung mit der ersten elektrischen Schnittstelleneinrichtung 22 eingehen könnten. Vorzugsweise ist die Aufnahme 43 komplett leer, besteht also aus einem leeren Hohlraum, der lediglich zur Ventil-Grundfläche 28 hin offen und im Übrigen vorzugsweise hermetisch dicht abgeschlossen ist. Auf diese Weise können auch unter ungünstigen Bedingungen keinerlei verunreinigungen oder Feuchtigkeit über die nichtelektrische Aufnahme 43 hinweg zu den elektrischen Antriebsmitteln 37 vordringen.Within the non-electrical receptacle 43 are no electrical contacts that could enter into electrical connection with the first electrical interface device 22. Preferably, the receptacle 43 is completely empty, so it consists of an empty cavity, which is open only to the valve base 28 and otherwise preferably hermetically sealed. In this way, even under unfavorable conditions, no contaminants or moisture can penetrate beyond the non-electrical receptacle 43 to the electric drive means 37.

Beide Typen der erfindungsgemäßen Mehrwegeventile 3 sind im Bereich der Ventil-Grundfläche 28 zweckmäßigerweise mit einer Dichtung 44 ausgestattet, die vom Ventilgehäuse getragen ist und die im einen Fall (Figuren 2 und 3) die dritte elektrische Schnittstelleneinrichtung 22 und im anderen Fall (Figuren 4 und 5) die Öffnung der nichtelektrischen Aufnahme 43 umrahmt. Bei nicht angebautem Mehrwegeventil 3 steht die Dichtung 44 geringfügig über die Ventil-Grundfläche 28 vor, so dass sie beim Ansetzen des Mehrwegeventils 3 an den Ventilträger 2 in dem die erste elektrische Schnittstelleneinrichtung 22 umrahmenden Bereich mit der Bestückungsfläche 4 des Ventilträgers 2 verpresst wird. Auf diese Weise ist ein wirksames Verhindern des Eindringens von Feuchtigkeit oder Verunreinigungen in die elektrischen Komponenten gegeben.Both types of multi-way valves 3 according to the invention are in the area of the valve base 28 expediently with a Seal 44 fitted, which is carried by the valve housing and in one case ( Figures 2 and 3 ) the third electrical interface device 22 and in the other case ( FIGS. 4 and 5 ) framed the opening of the non-electric recording 43. When the multi-way valve 3 is not fitted, the seal 44 protrudes slightly beyond the valve base 28, so that it is pressed together with the mounting surface 4 of the valve carrier 2 when the multi-way valve 3 is attached to the valve carrier 2 in the area framing the first electrical interface device 22. In this way, there is effectively prevented the penetration of moisture or contaminants into the electrical components.

Vorzugsweise befinden sich die zweite elektrische Schnittstelleneinrichtung 23 sowie, im einen Fall, die dritte elektrische Schnittstelleneinrichtung 24 und, im anderen Fall, die nichtelektrische Aufnahme 43, an der elektrischen Antriebseinrichtung 17, wobei sie exemplarisch ein Bestandteil der Vorsteuerstufe 36 sind. Mithin bedarf die erfindungsgemäße Ausgestaltung keiner Veränderungen an dem Steuerteil 33.Preferably, the second electrical interface device 23 and, in one case, the third electrical interface device 24 and, in the other case, the non-electrical receptacle 43, on the electric drive means 17, wherein they are an example of a component of the pilot stage 36. Thus, the inventive design requires no changes to the control part 33rd

Bei der Ventileinrichtung gemäß Figur 1 ist der Ventilträger 2 mit insgesamt drei erfindungsgemäß gestalteten Mehrwegeventilen 3 bestückt. Die zweiten elektrischen Schnittstelleneinrichtungen 23 sind jeweils gut ersichtlich. Ein viertes, ebenfalls an einem der Bestückungsplätze 6 installiertes Mehrwegeventil 45 ist hingegen von konventionellen Aufbau und ist so ausgebildet, dass ausschließlich über die interne Signalübertragungseinrichtung 16 eine Ansteuerung möglich ist. Es verfügt an seiner Ventil-Grundfläche über eine elektrische Schnittstelleneinrichtung, die in der aus Figuren 2 und 3 ersichtlichen Weise mit der ersten elektrischen Schnittstelleneinrichtung 22 des Ventilträgers 2 kontaktierbar ist, wobei es jedoch keine zusätzliche weitere elektrische Schnittstelleneinrichtung 23 für die alternative oder kumulative Signalzufuhr wie der eine Typ des erfindungsgemäßen Mehrwegeventils 3 verfügt.In the valve device according to FIG. 1 the valve carrier 2 is equipped with a total of three multi-way valves 3 designed according to the invention. The second electrical interface devices 23 are each clearly visible. A fourth multi-way valve 45, which is likewise installed at one of the placement stations 6, is of conventional design and is designed such that a control is possible exclusively via the internal signal transmission device 16. It has at its valve base an electrical interface device, which in the Figures 2 and 3 apparent manner with the first electrical interface device 22 of the valve carrier 2 is contacted, but there is no additional additional electrical interface device 23 for the alternative or cumulative signal supply as the one type of multi-way valve 3 according to the invention has.

Die Ventileinrichtung 1 enthält einen Ventilmix aus Mehrwegeventilen 3 des einen und des anderen Typs. Zusätzlich ist eine Kombination auch mit konventionellen Mehrwegeventilen 45 möglich.The valve device 1 contains a valve mix of multiway valves 3 of one and the other type. In addition, a combination with conventional multi-way valves 45 is possible.

Auch wenn die Ventileinrichtung 1 über einen Ventilträger 2 verfügt, der den Anbau von lediglich einem einzigen Mehrwegeventil 3 gestattet, kann der erfindungsgemäße Gedanke realisiert werden, indem ein Mehrwegeventil 3 angebaut wird, das zusätzlich zu der zweiten elektrischen Schnittstelleneinrichtung 23 entweder eine dritte elektrische Schnittstelleneinrichtung 24 oder eine nichtelektrische Aufnahme 43 aufweist.Even if the valve device 1 has a valve carrier 2, which allows the cultivation of only a single multi-way valve 3, the inventive concept can be realized by a multi-way valve 3 is attached, which in addition to the second electrical interface device 23, either a third electrical interface device 24th or a non-electric recording 43 has.

Zu der Vorsteuerstufe 36 sei noch erwähnt, dass deren mindestens ein elektrisch betätigbares Ventil beispielsweise ein Magnetventil oder ein Piezoventil oder ein elektrostatisches Ventil sein kann.To the pilot stage 36 should be mentioned that the at least one electrically actuated valve may be for example a solenoid valve or a piezo valve or an electrostatic valve.

Es ist ferner noch zu erwähnen, dass über die diversen elektrischen Schnittstelleneinrichtungen 22, 23, 24 nicht nur Betätigungssignale übertragen werden können, sondern bei Bedarf zusätzlich auch eine elektrische Versorgungsspannung anlegbar ist oder auch Sensorsignale aus dem Mehrwegeventil 3 abführbar sind, wenn letzteres mit einer entsprechenden Sensorik ausgestattet ist.It is also to be mentioned that not only actuation signals can be transmitted via the various electrical interface devices 22, 23, 24 but additionally an electrical supply voltage can also be applied if required or even sensor signals can be dissipated from the multiway valve 3, if the latter is provided with a corresponding one Sensor system is equipped.
