Dadurch ist gewährleistet, dass die 2/2-Wegeventile in der Stapelrichtung eine geringe Ausdehnung aufweisen und mit einer möglichst hohen Packungsdichte zu einer kompakten Ventileinrichtung zusammengefügt werden können. Die Querschnittshaupterstreckung ist die jeweils längste Gerade, die in der Querschnittsebene in den Querschnitt des 2/2-Wegeventils gelegt werden kann und parallel zu einer Außenoberfläche des 2/2-Wegeventils ausgerichtet ist. Beispielsweise ist die Querschnittshaupterstreckung bei einem Betätigungsmittel mit rechteckigen Querschnitt gleichbedeutend mit der Länge der längeren Außenkante des Rechteckquerschnitts des Betätigungsmittels.This ensures that the 2/2-way valves in the stacking direction have a small extent and can be assembled with the highest possible packing density to form a compact valve device. The cross-sectional main extension is the respective longest straight line, which can be placed in the cross-sectional plane in the cross section of the 2/2-way valve and is aligned parallel to an outer surface of the 2/2-way valve. For example, in the case of an actuating element with a rectangular cross-section, the cross-sectional main extension is equivalent to the length of the longer outer edge of the rectangular cross-section of the actuating means.

Vorteilhafte Weiterbildungen der Erfindung sind in den Unteransprüchen angegeben.Advantageous developments of the invention are specified in the subclaims.

Bei einer Ausführungsform der Erfindung ist vorgesehen, dass die 2/2-Wegeventile in der zur Bestückungsfläche parallelen Querschnittsebene eine Dickenerstreckung in Stapelrichtung aufweisen, die einen Bruchteil, vorzugsweise weniger als 50 Prozent, besonders bevorzugt weniger als 35 Prozent, insbesondere weniger als 25 Prozent, der Querschnittshaupterstreckung beträgt. Hierdurch lässt sich eine besonders kompakte Gestaltung der Ventilmodule erzielen.In one embodiment of the invention, it is provided that the 2/2-way valves in the cross-sectional plane parallel to the assembly surface have a thickness extension in the stacking direction which is a fraction, preferably less than 50 percent, particularly preferably less than 35 percent, in particular less than 25 percent. the cross-sectional main extension is. This makes it possible to achieve a particularly compact design of the valve modules.

Vorteilhaft ist es, wenn die Betätigungsmittel der 2/2-Wegeventile im Wesentlichen quaderförmig ausgebildet sind und parallel zu den Fügeflächen ausgerichtete Oberflächen der 2/2-Wegeventile in einer gemeinsamen Ebene angeordnet sind. In Kombination mit den plattenförmigen Kanalkörpern der Ventilmodule wird durch die quaderförmige Gestaltung der 2/2-Wegeventile eine besonders gute Raumausnutzung gewährleistet. Zudem wird durch die quaderförmige Gestaltung der 2/2-Wegeventile ein separater Austausch jedes der 2/2-Wegeventile begünstigt, ohne die Demontage benachbarter Ventilmodule zu erfordern. Die Anordnung der Oberflächen der 2/2-Wegeventile in einer gemeinsamen, parallel zu den Fügeflächen ausgerichteten Ebene gewährleistet, dass die 2/2-Wegeventile nicht versetzt zueinander angeordnet sind, da hierdurch eine kompakte Anordnung der Ventilmodule beeinträchtigt würde.It is advantageous if the actuating means of the 2/2-way valves are formed substantially cuboid and Parallel to the joining surfaces aligned surfaces of the 2/2-way valves are arranged in a common plane. In combination with the plate-shaped channel bodies of the valve modules, the cuboid design of the 2/2-way valves ensures particularly good space utilization. In addition, the cuboid design of the 2/2-way valves promotes a separate replacement of each of the 2/2-way valves, without requiring the disassembly of adjacent valve modules. The arrangement of the surfaces of the 2/2-way valves in a common, aligned parallel to the joining surfaces level ensures that the 2/2-way valves are not offset from each other, as a compact arrangement of the valve modules would be affected.

Bei einer Ausgestaltung der Erfindung ist vorgesehen, dass die Betätigungsmittel der 2/2-Wegeventile jeweils eine, vorzugsweise U-förmige, Rückschlusseinrichtung mit mehreren Schenkeln aufweisen, die an einem Ende mittels eines Verbindungsstegs miteinander verbunden sind, jeweils abschnittsweise von Spulenmitteln umfasst sind und senkrecht zur Bestückungsfläche ausgerichtet sind. Die zur Betätigung des Ventilglieds notwendige Betätigungskraft wird von den wenigstens zwei Spulenmitteln, bei denen es sich exemplarisch jeweils um elektrisch ansteuerbare Magnetspulen handelt, bereitgestellt. Durch die Verwendung von wenigstens zwei Magnetspulen, deren Spulenachsen parallel zueinander ausgerichtet sind und die die benachbarten Schenkel der Rückschlusseinrichtung umgeben, wird eine besonders kompakte Gestaltung der Betätigungseinrichtung des 2/2-Wegeventils ermöglicht. Der magnetische Fluss für die Bewegung des Ventilglieds wird erfindungsgemäß durch die schlank gestalteten Spulenmittel hervorgerufen, die quer zur Stapelrichtung in dem länglich ausgebildeten Betätigungsmittel des 2/2-Wegeventils angeordnet sind.In one embodiment of the invention, it is provided that the actuating means of the 2/2-way valves each have a, preferably U-shaped, return device with a plurality of legs, which are interconnected at one end by means of a connecting web, are each partially covered by coil means and vertically are aligned to the mounting surface. The actuation force necessary for actuating the valve member is provided by the at least two coil means, which are each exemplarily electrically controllable solenoid coils. By using at least two magnetic coils, the coil axes are aligned parallel to each other and surrounding the adjacent legs of the return device, a particularly compact design of the actuator of the 2/2-way valve is possible. The magnetic flux for the movement of the valve member is inventively caused by the slender designed coil means, which are arranged transversely to the stacking direction in the elongated actuating means of the 2/2-way valve.

Zweckmäßig ist es, wenn die Speisekanalausnehmung und/oder die Entlüftungskanalausnehmung den Kanalkörper zwischen den Fügeflächen in Stapelrichtung durchsetzen und an den Fügeflächen ausmünden, so dass die mit den Fügeflächen aneinander anliegenden Kanalkörper einen durchgehenden Speisekanal und/oder einen durchgehenden Entlüftungskanal begrenzen. Die Speisekanalausnehmung und/oder die Entlüftungskanalausnehmung sind in dem Kanalkörper der Ventileinrichtung derart angeordnet, dass sie bei Anordnung der Kanalkörper in der Stapelrichtung zumindest bereichsweise, vorzugsweise vollständig, mit den Speisekanalausnehmungen und/oder den Entlüftungskanalausnehmungen benachbarter Kanalkörper in Überdeckung gebracht werden können. Vorzugsweise sind die Speisekanalausnehmung und/oder die Entlüftungskanalausnehmung in jedem der Kanalkörper der Ventileinrichtung an der gleichen Position angeordnet. Dadurch ist gewährleistet, dass die längs der Stapelrichtung erstreckten Speise- und/oder Entlüftungskanäle mit erheblich größeren freien Querschnitten ausgebildet werden können, als dies für einzeln an den jeweiligen Kanalkörpern vorgesehene Speise- und/oder Entlüftungskanäle der Fall wäre. Hierdurch können bei gegebenem Fluidspeisedruck aufgrund des geringeren Strömungswiderstands in den erfindungsgemäßen Speise- und/oder Entlüftungskanälen große Fluidvolumenströme für das strömende Fluid erreicht werden.It is expedient if the feed channel recess and / or the vent channel opening pass through the channel body between the joining surfaces in the stacking direction and open out at the joining surfaces, so that the channel bodies adjacent to one another with the joining surfaces define a continuous feed channel and / or a continuous vent channel. The feed channel recess and / or the vent channel recess are arranged in the channel body of the valve device such that they can be brought in the stacking direction at least partially, preferably completely, with the Speisekanalausnehmungen and / or the vent channel recesses adjacent channel body in the stacking direction. Preferably, the feed channel recess and / or the vent channel recess in each of the channel bodies of the valve device are arranged at the same position. This ensures that the feeding and / or venting ducts extending along the stacking direction can be formed with substantially larger free cross sections than would be the case for feed and / or venting ducts provided individually on the respective duct bodies. As a result, large fluid volume flows for the flowing fluid can be achieved at a given fluid supply pressure due to the lower flow resistance in the feed and / or ventilation channels according to the invention.

Zweckmäßig ist es, wenn der Kanalkörper einstückig ausgebildet ist. Dadurch werden aufwändige Dichtmaßnahmen zwischen den einzelnen 2/2-Wegeventilen und den ihnen zugeordneten Fluidkanälen reduziert bzw. gänzlich vermieden. Der Kanalkörper kann beispielsweise aus Metall, insbesondere als Frästeil, Druckgussteil oder Feingussteil hergestellt sein. Alternativ kann der Kanalkörper als Kunststoffteil, insbesondere als Kunststoffspritzgussteil, ausgebildet sein.It is expedient if the channel body is formed in one piece. As a result, elaborate sealing measures between the individual 2/2-way valves and their associated fluid channels are reduced or completely avoided. The channel body may for example be made of metal, in particular as a milled part, die-cast part or precision casting. Alternatively, the channel body may be formed as a plastic part, in particular as a plastic injection molded part.

Vorteilhaft ist es, wenn 2/2-Wegeventile als Ventileinheiten ausgebildet sind, bei denen das Betätigungsmittel mit einem Ventilabschnitt eine kompakte Einheit bildet, die auf die Bestückungsfläche des Kanalkörpers aufgesetzt ist, wobei der Ventilabschnitt den ersten und den zweiten Fluidanschluss sowie einen Ventilsitz umfasst, gegenüber dem das Ventilglied beweglich angeordnet ist, um den freien Fluidkanalquerschnitt zwischen dem ersten und dem zweiten Fluidanschluss zwischen einer Sperrstellung und einer Freigabestellung zu beeinflussen. Bei dieser Ausführungsform der Erfindung sind die 2/2-Wegeventile vollständig außerhalb des Kanalkörpers ausgebildet und sind als kompakte Einheiten auf die Bestückungsfläche des Kanalkörpers aufgesetzt. Die 2/2-Wegeventile weisen neben dem elektrisch ansteuerbaren Betätigungsmittel den Ventilabschnitt auf, der der Fluidführung dient. Der Ventilabschnitt weist einen Fluidkanal auf, der an einer Außenoberfläche in zwei voneinander beabstandete Fluidanschlüsse ausmündet. Im Fluidkanal ist ein Ventilsitz ausgebildet, der eine abdichtende Anlage des Ventilglieds zur Sperrung des freien Querschnitts des Fluidkanals ermöglicht. Das Ventilglied kann durch eine vom Betätigungsmittel ausgehende Krafteinwirkung aus einer abdichtenden Anlage am Ventilsitz in eine Freigabestellung bewegt werden, in der der Ventilsitz und somit der Fluidkanalquerschnitt freigeben sind Das Betätigungsmittel kann also das Ventilglied derart beeinflussen, dass dieses entweder die Sperrstellung oder die Freigabestellung einnimmt.It is advantageous if 2/2-way valves are designed as valve units, in which the actuating means with a valve portion forms a compact unit which is placed on the mounting surface of the channel body, wherein the valve portion comprises the first and the second fluid port and a valve seat, opposite to which the valve member is movably arranged to influence the free fluid channel cross section between the first and the second fluid connection between a blocking position and a release position. In this embodiment of the invention, the 2/2-way valves are formed completely outside the channel body and are mounted as compact units on the mounting surface of the channel body. The 2/2-way valves have, in addition to the electrically controllable actuating means on the valve portion, which serves the fluid guide. The valve portion has a fluid channel, which opens at an outer surface into two spaced-apart fluid ports. In the fluid channel, a valve seat is formed, which allows a sealing engagement of the valve member to block the free cross section of the fluid channel. The valve member can be moved by a force exerted by the actuating force from a sealing contact with the valve seat in a release position in which the valve seat and thus the fluid channel cross section are free. The actuating means can thus influence the valve member such that it occupies either the blocking position or the release position.

Die Außenoberfläche des Ventilabschnitts, in der die Fluidanschlüsse ausmünden ist zur flächigen, abdichtenden Anlage an der Bestückungsfläche des Kanalkörpers vorgesehen. Die Fluidanschlüsse sind für kommunizierende Verbindungen mit Fluidkanälen im Kanalkörper vorgesehen. Durch die Ausführung der 2/2-Wegeventile als Ventileinheiten wird einerseits die Gestaltung des Kanalkörpers vereinfacht, da dieser keine Einrichtungen zur Bildung oder Aufnahme eines Ventilsitzes und des zugeordneten Ventilglieds aufweisen muss. Andererseits wird die Wartung der Ventilmodule erleichtert, da defekte 2/2-Wegeventile in einfacher Weise abgebaut und durch intakte 2/2-Wegeventile ersetzt werden können. Vorzugsweise sind die Ventileinheiten auf den Kanalkörper aufgeschraubt und weisen jeweils um die Fluidanschlüsse umlaufende Dichtmittel auf, um eine abdichtende Verbindung zwischen Ventilabschnitt und Bestückungsfläche des Kanalkörpers zu erreichen.The outer surface of the valve section, in which the fluid connections open out, is provided for flat, sealing engagement with the component surface of the channel body. The fluid connections are provided for communicating connections with fluid channels in the channel body. By the execution of 2/2-way valves as valve units, on the one hand simplifies the design of the channel body, since this does not have to have means for forming or receiving a valve seat and the associated valve member. On the other hand, the maintenance of the valve modules is facilitated because defective 2/2-way valves can be easily removed and replaced by intact 2/2-way valves. Preferably, the valve units are screwed onto the channel body and each have around the fluid connections circumferential sealing means in order to achieve a sealing connection between the valve portion and mounting surface of the channel body.

Eine in der Figur 1 dargestellte Ventileinrichtung 1 ist zur fluidischen Versorgung mehrerer, nicht dargestellter fluidischer Verbraucher, beispielsweise pneumatischer Arbeitszylinder, vorgesehen. Die Ventileinrichtung 1 dient zur Steuerung und/oder Regelung einer Vielzahl von Fluidströmen, die von einer nicht dargestellten Fluidquelle an die jeweiligen fluidischen Verbraucher bereitgestellt werden sollen.One in the FIG. 1 Valve device 1 shown is for fluidic supply of a plurality, not shown fluidic consumers, such as pneumatic cylinder, is provided. The valve device 1 is used to control and / or regulate a plurality of fluid streams to be provided by a fluid source, not shown, to the respective fluidic consumers.

Die Ventileinrichtung 1 umfasst mehrere, exemplarisch scheibenartig ausgebildete, Ventilmodule 2, die in einer Stapelrichtung 3 aneinander aufgereiht sind. Die Ventilmodule 2 sind zwischen einem Basiselement 4 und einer Abschlussplatte 5 angeordnet, die die Ventileinrichtung 1 längs der Stapelrichtung 3 jeweils endseitig begrenzen.The valve device 1 comprises a plurality of exemplary disk-like valve modules 2 which are lined up in a stacking direction 3. The valve modules 2 are arranged between a base element 4 and a closure plate 5, which delimit the valve device 1 along the stacking direction 3 at each end.

Einigen der Ventilmodule 2 sind Zusatzmodule 6, 7 zugeordnet, die beispielsweise als Ventilelemente oder Sensorelemente ausgebildet sind. Die Zusatzmodule 6, 7 sind, wie dies aus der Figur 1 hervorgeht, in einer Montagerichtung 92 orthogonal zur Stapelrichtung 3 aneinander anreihbar und ermöglichen bei Bedarf die Erweiterung des Funktionsumfangs der Ventilmodule 2. Die Ventilmodule 2 der Ventileinrichtung 1 sind jedoch auch ohne die zugeordneten Zusatzmodule 6, 7 einsetzbar.Some of the valve modules 2 are associated with additional modules 6, 7, which are designed for example as valve elements or sensor elements. The additional modules 6, 7 are, as can be seen from the FIG. 1 shows, in an assembly direction 92 orthogonal to the stacking direction 3 juxtaposed and allow, if necessary, the extension of the functional scope of the valve modules 2. The valve modules 2 of the valve device 1, however, can also be used without the associated additional modules 6, 7.

Das Basiselement 4 ist vorliegend quaderförmig ausgebildet und weist an einer Stirnfläche 8, deren Flächennormale orthogonal zur Stapelrichtung 3 ausgerichtet ist, eine Speiseöffnung 9 zum Anschluss eines nicht dargestellten Fluidleiters auf. Der Fluidleiter ist für eine kommunizierende Verbindung mit der nicht dargestellten Fluidquelle vorgesehen, von der beispielsweise druckbeaufschlagtes oder unterdruckbeaufschlagtes Fluid bereitgestellt wird. Das Basiselement 4 weist weiterhin eine Entlüftungsöffnung 10 auf, die beispielsweise als Austritt für Fluid.dienen kann, das bereits die Ventileinrichtung 1 und die nicht dargestellten fluidischen Verbraucher durchströmt hat. Bei Einsatz der Ventileinrichtung 1 zur Steuerung und/oder Regelung von Gasströmen, insbesondere von Druckluftströmen, kann an der Entlüftungsöffnung 10 des Basiselements 4 ein nicht dargestellter Schalldämpfer angeordnet werden.In the present case, the base element 4 is cuboid-shaped and has a feed opening 9 for connecting a fluid conductor, not shown, on an end face 8 whose surface normal is oriented orthogonally to the stacking direction 3. The fluid conduit is provided for communicating communication with the fluid source, not shown, from which, for example, pressurized or vacuum pressurized fluid is provided. The base member 4 further has a vent opening 10, which can serve as an outlet for fluid, for example has already flowed through the valve device 1 and the fluidic consumers, not shown. When using the valve device 1 for controlling and / or regulating gas flows, in particular compressed air streams, a silencer, not shown, can be arranged on the vent opening 10 of the base element 4.

Bei der dargestellten Ausführungsform der Ventileinrichtung 1 sind an das Basiselement 4 in Stapelrichtung 3 mehrere Ventilmodule 2 aufgereiht, die alle den gleichen, nachstehend näher beschriebenen, Aufbau aufweisen. Den Ventilmodulen 2 kommt die Aufgabe zu, das über das Basiselement 4 bereitgestellte Fluid in der gewünschten Weise an die nicht dargestellten fluidischen Verbraucher abzugeben und gegebenenfalls von fluidischen Verbrauchern zurückströmendes Fluid wieder zum Basiselement 4 zurückzuführen.In the illustrated embodiment of the valve device 1, a plurality of valve modules 2 are lined up on the base element 4 in the stacking direction 3, all of which have the same structure, described in more detail below. The task of the valve modules 2 is to dispense the fluid provided via the base element 4 in the desired manner to the fluidic consumers (not shown) and, if appropriate, to return the fluid flowing back from the fluidic consumers back to the base element 4.

Jedes der in den Figuren 2 bis 5 näher dargestellten Ventilmodule 2 umfasst einen plattenförmig ausgebildeten Kanalkörper 11 und auf den Kanalkörper 11 aufgesetzte, gleichförmig ausgebildete Ventileinheiten 12. Die Ventileinheiten 12 des Ventilmoduls 2 sind mit einer Abdeckleiste 13 versehen, die beispielsweise zur Geräuschdämmung und/oder zur Abschirmung der Ventileinheiten 12 vor Umwelteinflüssen, insbesondere Verschmutzungen, und/oder zur elektrischen Kontaktierung der Ventileinheiten 12 ausgebildet sein kann. Die Ventileinheit 12 des Zusatzmoduls 6 ist mit einer Abdeckhaube 14 versehen, die die gleiche Funktionalität für die einzelne Ventileinheit 12 wie die Abdeckleiste 13 für die mehreren Ventileinheiten 12 des Ventilmoduls 2 verwirklicht.Each of the in the FIGS. 2 to 5 The valve units 12 of the valve module 2 are provided with a cover strip 13, for example, for noise reduction and / or for shielding the valve units 12 from environmental influences, in particular dirt, and / or for electrical contacting of the valve units 12 may be formed. The valve unit 12 of the additional module 6 is provided with a cover 14, which realizes the same functionality for the single valve unit 12 as the cover strip 13 for the plurality of valve units 12 of the valve module 2.

Der Kanalkörper 11, der beispielsweise eine kubische Außengeometrie aufweisen kann, weist zwei einander entgegengesetzte Fügeflächen 15, 16 auf, deren nicht dargestellte Flächennormalen parallel zur Stapelrichtung 3 ausgerichtet sind. Beispielsweise weist die erste Fügefläche 15 in Richtung des Basiselements 4, entsprechend weist die zweite Fügefläche 16 in Richtung der Abschlussplatte 5. Die Fügeflächen 15, 16 bilden bei der dargestellten Ausführungsform des Kanalkörpers 11 dessen größte Oberflächen. Von den zu den Fügeflächen 15, 16 orthogonal ausgerichteten Schmalseiten des Kanalkörpers 11, deren nicht dargestellte Flächennormalen senkrecht zur Stapelrichtung 3 verlaufen, dient eine kürzere Schmalseite als Anschlussfläche 17 und eine längere Schmalseite als Bestückungsfläche 18.The channel body 11, which may for example have a cubic outer geometry, has two mutually opposite joining surfaces 15, 16, the surface normal, not shown aligned parallel to the stacking direction 3. For example, the first joining surface 15 in the direction of the base member 4, accordingly, the second joining surface 16 in the direction of the end plate 5. The joining surfaces 15, 16 form in the illustrated embodiment of the channel body 11 whose largest surfaces. Of the to the joining surfaces 15, 16 orthogonally oriented narrow sides of the channel body 11, the non-illustrated surface normal extending perpendicular to the stacking direction 3, serves a shorter narrow side as a connection surface 17 and a longer narrow side than mounting surface 18th

Bei dem in den Figuren 3 bis 5 näher dargestellten Ventilmodul 2 münden an der Anschlussfläche 17 Anschlussöffnungen 19, 20 der nachfolgend näher beschriebenen Arbeitskanäle 21, 22 aus. An der Bestückungsfläche 18 münden Anschlussbohrungen 25, 26, 27 und 28 der Arbeitskanäle 21, 22 aus, wie dies aus den Figuren 4 und 5 hervorgeht. An der Bestückungsfläche 18 münden zudem Verbindungsbohrungen 29, 30, 31, 32 aus, die mit nachfolgend näher beschriebenen Speisekanalausnehmungen 35 bzw. Entlüftungskanalausnehmungen 36 im Kanalkörper 11 kommunizierend verbunden sind.In the in the FIGS. 3 to 5 shown valve module 2 open at the connection surface 17 connection openings 19, 20 of the working channels 21, 22 described in more detail below. On the mounting surface 18 open connection bores 25, 26, 27 and 28 of the working channels 21, 22, as is known from FIGS. 4 and 5 evident. Connecting holes 29, 30, 31, 32 which open out and communicate with feeding channel recesses 35 or vent channel recesses 36 in the channel body 11, which are described in greater detail below, also open out of the mounting surface 18.

Wie den Figuren 2 bis 5 entnommen werden kann, wird der Kanalkörper 11 in Stapelrichtung 3 von zwei Ausnehmungen durchsetzt, die als Speisekanalausnehmung 35 bzw. als Entlüftungskanalausnehmung 36 dienen und die in einer Querschnittsebene, deren Normalenvektor parallel zur Stapelrichtung 3 ausgerichtet ist, eine längliche Erstreckung aufweisen. In den Figuren 4 und 5 sind jeweils eine Querschnittshaupterstreckung 37 der Speisekanalausnehmung 35 und eine Querschnittshaupterstreckung 38 der Entlüftungskanalausnehmung 36 eingezeichnet. Bei der Querschnittshaupterstreckung 37, 38 handelt es sich jeweils um eine Gerade, die sich vorliegend querschnittsmittig mit maximaler Länge innerhalb einer Berandung des jeweiligen Querschnitts der Speisekanalausnehmung 35 bzw. der Entlüftungskanalausnehmung 36 erstreckt. Die Querschnittshaupterstreckungen 37, 38 sind bei der vorliegenden Ausführungsform des Kanalkörpers 11 koaxial zueinander ausgerichtet und verlaufen parallel zur nicht dargestellten Flächennormale der Anschlussfläche 17.Like that FIGS. 2 to 5 can be removed, the channel body 11 is penetrated in the stacking direction 3 of two recesses, which serve as Speisekanalausnehmung 35 and 36 as Entlüftungskanalausnehmung and which have a longitudinal extension in a cross-sectional plane whose normal vector is aligned parallel to the stacking direction 3. In the FIGS. 4 and 5 In each case, a cross-sectional main extension 37 of the feed channel recess 35 and a cross-sectional main extension 38 of the vent channel recess 36 are shown. In the cross-sectional main extension 37, 38 are each a straight line, which is present extending transversely centrally with maximum length within a boundary of the respective cross section of the feed channel recess 35 and the vent channel recess 36. The cross-sectional main stretches 37, 38 are in the present embodiment of the channel body 11 coaxially aligned with each other and parallel to the surface normal, not shown, the pad 17th

Wie aus der Explosionsdarstellung der Figur 2 entnommen werden kann, bilden die Speisekanalausnehmung 35 und die Entlüftungskanalausnehmung 36 der in Stapelrichtung 3 aufgereihten Kanalkörper 11 der Ventilmodule 2 einen sich zwischen dem Basiselement 4 und der Abschlussplatte 5 erstreckenden, durchgängigen Speisekanal, der durch den Pfeil 39 symbolisiert wird, und einen durchgängigen Entlüftungskanal, der durch den Pfeil 40 symbolisiert wird. Dadurch wird eine zentrale Verund Entsorgung der Ventilmodule 2 mit bzw. von Fluid ermöglicht.As from the exploded view of the FIG. 2 can be removed form the Speisekanalausnehmung 35 and the Enttüftungskanalausnehmung 36 of stacked in the stacking direction 3 channel body 11 of the valve modules 2 extending between the base member 4 and the end plate 5, continuous feed channel, which is symbolized by the arrow 39, and a continuous venting channel, which is symbolized by the arrow 40. As a result, central disposal of the valve modules 2 with or from fluid is made possible.

Wie den Figuren 4 und 5 zu entnehmen ist, erstrecken sich die Arbeitskanäle 21 und 22 jeweils zwischen den an der Anschlussfläche 17 vorgesehenen Anschlussöffnungen 20 bzw. 19 und den an der Bestückungsfläche 18 vorgesehenen Anschlussbohrungen 25 und 28 bzw. 26 und 27.Like that FIGS. 4 and 5 can be seen, the working channels 21 and 22 each extend between the provided on the connection surface 17 connection openings 20 and 19 and provided on the mounting surface 18 connection bores 25 and 28 or 26 and 27th

Der erste Arbeitskanal 21 stellt eine kommunizierende Verbindung zwischen dem an der Anschlussöffnung 20 anschließbaren fluidischen Verbraucher und dem ersten 2/2-Wegeventil 41 sowie dem vierten 2/2-Wegeventil 46 bereit. Der zweite Arbeitskanal 22 ist für eine kommunizierende Verbindung zwischen der Anschlussöffnung 19 und dem zweiten 2/2-Wegeventil 42 sowie dem dritten 2/2-Wegeventil 45 vorgesehen.The first working channel 21 provides a communicating connection between the fluidic load connectable to the connection opening 20 and the first 2/2-way valve 41 and the fourth 2/2-way valve 46. The second working channel 22 is provided for a communicating connection between the connection opening 19 and the second 2/2-way valve 42 and the third 2/2-way valve 45.

In der ersten Fügefläche 15 sind nutartige Vertiefungen 61, 62 eingebracht. Die nutartigen Vertiefungen 61, 62 bilden jeweils einen Abschnitt des Arbeitskanals 21 bzw. 22. Die nutartige Vertiefung 61 steht über die beispielsweise als senkrecht zu den Fügeflächen 15, 16 ausgerichteten, als Stichbohrungen ausgeführten Arbeitskanalbohrungen 57, 58 in kommunizierender Verbindung mit der zweiten Anschlussöffnung 20 an der Anschlussfläche 17 und mit den Anschlussbohrungen 25 und 28 an der Bestückungsfläche 18. Die nutartige Vertiefung 62 steht über die zugeordneten Arbeitskanalbohrungen 59, 60, 63 in kommunizierender Verbindung mit der Anschlussöffnung 19 an der Anschlussfläche 17 und mit den Anschlussbohrungen 26 und 27 an der Bestückungsfläche 18.In the first joining surface 15 groove-like depressions 61, 62 are introduced. The groove-like depressions 61, 62 each form a section of the working channel 21 or 22. The groove-like depression 61 is in communication with the second connection opening 20 via the working channel bores 57, 58 which are aligned, for example, as perpendicular to the joining surfaces 15, 16 on the connection surface 17 and with the connection bores 25 and 28 on the mounting surface 18. The groove-like recess 62 is connected via the associated working channel bores 59, 60, 63 in communicating connection with the connection opening 19 on the connection surface 17 and with the connection bores 26 and 27 on the Assembly area 18.

Die kreuzungsfreie Anordnung der fluidischen Verbindungen ist in den Figuren 4 und 5 ersichtlich, in denen die nutartigen Vertiefungen 61, 62 gestrichelt dargestellt sind, da sie in der zur dargestellten Schnittebene beabstandet angeordneten zweiten Fluidkanalebene 34 liegen, wie dies beispielsweise aus der Figur 3 entnommen werden kann.The crossing-free arrangement of the fluidic connections is in the FIGS. 4 and 5 can be seen in which the groove-like recesses 61, 62 are shown in dashed lines, since they are in the plane shown to the sectional plane arranged second fluid channel plane 34, as for example from the FIG. 3 can be removed.

Der Figur 3 sind nutartige Ausnehmungen 65, 66, 67, 68 zu entnehmen, die jeweils umlaufend um die Speisekanalausnehmung 35, um die Entlüftungskanalausnehmung 36, um die nutartige Vertiefung 61 und um die nutartige Vertiefung 62 angeordnet sind. Diese dienen zur Aufnahme von nicht dargestellten, beispielsweise als endlose Rundschnurdichtungen ausgeführten Dichtmitteln.Of the FIG. 3 are groove-like recesses 65, 66, 67, 68 respectively, which are arranged circumferentially around the feed channel recess 35, to the vent passage recess 36 to the groove-like recess 61 and the groove-like recess 62. These serve to receive sealants, not shown, for example, designed as endless round cord seals.

Der Aufbau des in der Figur 6 exemplarisch näher dargestellten 2/2-Wegeventils 46 ist stellvertretend für sämtliche in den Figuren 1 bis 5 dargestellten 2/2-Wegeventile 41, 42, 45 46. Das 2/2-Wegeventil 46 ist als kompakte Ventileinheit 12 im Wesentlichen aus einem elektromagnetischem Betätigungsmittel 76, einem Ventilabschnitt 77 und einer zwischen Betätigungsmittel 76 und Ventilabschnitt 77 aufgenommenen Distanzplatte 78 aufgebaut. Exemplarisch weisen das Betätigungsmittel 76, der Ventilabschnitt 77 die Distanzplatte 78 in einer nicht dargestellten, parallel zur Bestückungsfläche 18 ausgerichteten Querschnittsebene die gleiche Außenkontur auf.The construction of the in the FIG. 6 exemplified in detail 2/2-way valve 46 is representative of all in the FIGS. 1 to 5 shown 2/2-way valves 41, 42, 45 46. The 2/2-way valve 46 is a compact valve unit 12 essentially of an electromagnetic actuating means 76, a valve portion 77 and a recorded between the actuator 76 and valve portion 77 spacer plate 78 constructed. By way of example, the actuating means 76, the valve portion 77, the spacer plate 78 in a non-illustrated, parallel to the mounting surface 18 aligned cross-sectional plane on the same outer contour.

Bei der vorliegenden, exemplarisch rechteckigen Außenkontur der kubisch geformten 2/2-Wegeventile entspricht ist die in der Figur 3 dargestellte Querschnittshaupterstreckung 90 gleichbedeutend mit der längsten, in der Ebene der Bestückungsfläche 18 liegenden Kante des Betätigungsmittels 76. Die Querschnittshaupterstreckungen 90 der benachbart angeordneten 2/2-Wegeventile 41, 42, 45, 46 des jeweiligen Ventilmoduls 2 sind koaxial zueinander ausgerichtet. Die parallel zu den Fügeflächen 15, 16 ausgerichteten Oberflächen 91 der 2/2-Wegeventile 41, 42, 45, 46 sind in einer gemeinsamen Ebene 93 angeordnet.In the present, exemplary rectangular outer contour of the cubic shaped 2/2-way valves corresponds to the in the FIG. 3 shown cross-sectional main extension 90 is equivalent to the longest, lying in the plane of the mounting surface 18 edge of the actuating means 76. The cross-sectional main stretches 90 of the adjacently arranged 2/2-way valves 41, 42, 45, 46 of the respective valve module 2 are aligned coaxially with each other. The surfaces 91 of the 2/2-way valves 41, 42, 45, 46 oriented parallel to the joining surfaces 15, 16 are arranged in a common plane 93.

Das in der Figur 6 näher dargestellte elektromagnetische Betätigungsmittel 76 umfasst einen U-förmigen, aus mehreren Einzelplatten zusammengesetzten Eisenrückschluss 79, an dessen parallel zueinander ausgerichteten Schenkeln 82, 85 jeweils aus nicht näher dargestellten Drahtwindungen aufgebaute elektromagnetische Spulenkörper 80, 81 angeordnet sind. Die im Wesentlichen zylinderhülsenförmig ausgebildeten Spulenkörper 80, 81 können mittels nicht näher dargestellter elektrischer Verbindungsleitungen mit elektrischer Energie beaufschlagt werden. Die beiden Schenkel 82, 85 des Eisenrückschluss 79 werden durch einen Verbindungssteg 86 miteinander verbunden, der einen magnetischen Fluss zwischen den beiden Schenkeln 82, 85 gestattet.That in the FIG. 6 electromagnetic actuating means 76 shown in detail comprises a U-shaped, composed of a plurality of individual plates iron yoke 79, on whose parallel aligned legs 82, 85 respectively constructed of wire turns not shown electromagnetic coil body 80, 81 are arranged. The substantially cylindrical sleeve-shaped bobbin 80, 81 can be acted upon by means not shown electrical connection lines with electrical energy. The two legs 82, 85 of the iron yoke 79 are interconnected by a connecting web 86, which allows a magnetic flux between the two legs 82, 85.

An einer dem Verbindungssteg 86 entgegengesetzten Stirnseite der Schenkel 82, 85 ist ein vorliegend plattenförmig ausgebildetes Ventilglied 87 angeordnet, dessen Dicke geringer gewählt ist als die Dicke der Distanzplatte 78. Dadurch kann das Ventilglied 87 zwischen einer dem Eisenrückschluss 79 beabstandeten Sperrstellung, wie sie in der Figur 6 dargestellt ist, und einer am Eisenrückschluss 79 anliegenden Freigabestellung, in der Darstellung der Figur 6 auf- und abwärts, bewegt werden.At one of the connecting web 86 opposite end side of the legs 82, 85 a present plate-shaped valve member 87 is arranged, whose thickness is chosen smaller than the thickness of the spacer plate 78. Thus, the valve member 87 between the iron yoke 79 spaced blocking position, as shown in the FIG. 6 is shown, and a voltage applied to the iron yoke 79 release position, in the illustration of FIG. 6 up and down, to be moved.

Eine Bewegung des Ventilglieds 87 aus der in Figur 6 dargestellten Sperrstellung nach oben in die nicht dargestellte Freigabestellung kann stattfinden, wenn die Spulenkörper 80, 81 des elektromagnetischen Betätigungsmittels 76 mit elektrischer Energie beaufschlagt werden. Hierdurch wird in den Spulenkörpern 80, 81 ein Magnetfeld aufgebaut und an die freien Enden der Schenkel 82, 85 des Eisenrückschluss 79 geführt, durch dessen Anziehungskraft das aus magnetisierbarem Material hergestellte Ventilglied 87 in Richtung des Eisenrückschluss 79 bewegt werden kann.A movement of the valve member 87 from the in FIG. 6 illustrated blocking position upwards in the release position, not shown, can take place when the coil body 80, 81 of the electromagnetic actuating means 76 are acted upon by electrical energy. In this way, a magnetic field is built up in the bobbins 80, 81 and guided to the free ends of the legs 82, 85 of the iron yoke 79, by the attractive force of which the valve member 87 made of magnetizable material can be moved in the direction of the iron yoke 79.

In der Sperrstellung verschließt das Ventilglied 87 einen Durchgang 83 zwischen einer Ventilkammer 88, die vom elektromagnetischen Betätigungsmittel 76, vom Ventilabschnitt 77 und von der Distanzplatte 78 begrenzt wird und dem zweiten Fluidanschluss 56. Die Ventileinheit 12 ist spiegelsymmetrisch zu einer Spiegelebene ausgebildet, die normal zur Darstellungsebene der Figur 6 ausgerichtet ist. Dementsprechend steht die Ventilkammer 88 mit den zwei ersten Fluidanschlüssen 55, die symmetrisch zum ersten Fluidanschluss 56 angeordnet sind, in kommunizierender Verbindung.In the blocking position, the valve member 87 closes a passage 83 between a valve chamber 88 bounded by the electromagnetic actuator 76, the valve portion 77 and the spacer plate 78 and the second fluid port 56. The valve unit 12 is mirror-symmetrical to a mirror plane normal to Presentation level of FIG. 6 is aligned. Accordingly, the valve chamber 88 communicates with the two first fluid ports 55, which are arranged symmetrically with respect to the first fluid port 56, in communicating connection.

Sofern am ersten Fluidanschluss 55 und damit auch in der Ventilkammer 88 ein Überdruck gegenüber dem zweiten Fluidanschluss 56 vorliegt, wirkt eine resultierende Druckkraft auf das Ventilglied 87, die gemäß der Darstellung der Figur 6 nach unten gerichtet ist. Ohne eine entsprechende, vom elektromagnetischen Betätigungsmittel 76 bereitgestellte und in entgegengesetzer Richtung wirkende magnetische Anziehungskraft wird das Ventilglied 87 auf einen im Ventilabschnitt 77 ausgebildeten Ventilsitz 89 gepresst, wodurch der Durchgang 83 zwischen dem ersten und dem zweiten Fluidanschluss 55, 56 verschlossen ist.If at the first fluid port 55 and thus also in the valve chamber 88, an overpressure relative to the second fluid port 56 is present, a resulting pressure force acts on the valve member 87, as shown in the FIG. 6 directed downwards. Without a corresponding magnetic attraction provided by the electromagnetic actuator 76 and acting in the opposite direction, the valve member 87 is pressed onto a valve seat 89 formed in the valve portion 77, thereby closing the passage 83 between the first and second fluid ports 55,56.

Bei Beaufschlagung des elektromagnetischen Betätigungsmittels 76 mit elektrischer Energie übt dieses eine magnetische Anziehungskraft auf das Ventilglied 87 aus. Mit der magnetischen Anziehungskraft kann die resultierende Druckkraft auf das Ventilglied 87 überwunden werden, so dass das Ventilglied 87 vom Ventilsitz 89 abgehoben wird und den Durchgang 83 freigibt. Somit kann Fluid zwischen dem ersten Fluidanschluss 55 und dem zweiten Fluidanschluss 56 strömen.Upon application of electrical energy to the electromagnetic actuator 76, it exerts a magnetic force of attraction on the valve member 87. With the magnetic attraction force, the resulting pressure force on the valve member 87 can be overcome, so that the valve member 87 is lifted from the valve seat 89 and the passage 83 releases. Thus, fluid may flow between the first fluid port 55 and the second fluid port 56.

Bei der vorliegenden Ausführungsform eines Ventilmoduls 2 sind sämtliche 2/2-Wegeventile 41, 42, 45, 46 derart angeordnet, dass sie bei der typischerweise vorgesehenen Überdruckbeaufschlagung der Speisekanalausnehmung 35 jeweils einen Überdruck in der zugeordneten Ventilkammer 88 gegenüber dem ersten Fluidanschluss 47, 49, 51, 55 aufweisen und dadurch in einer normal geschlossenen Position gehalten werden.In the present embodiment of a valve module 2, all of the 2/2-way valves 41, 42, 45, 46 are arranged such that they each have an overpressure in the associated valve chamber 88 with respect to the first fluid port 47, 49 in the typically provided overpressurization of the Speisekanalausnehmung 35, 51, 55 and thereby held in a normally closed position.

Aufgrund der Ausführung des elektromagnetischen Betätigungsmittels 76 mit zwei durch den Eisenrückschluss 79 magnetisch miteinander gekoppelten Spulenkörpern 80, 81 kann die Ventileinheit 12, die bei dem Ausführungsbeispiel in den 2/2-Wegeventilen 41, 42, 45, 46 verwirklicht ist, eine längliche Gestalt aufweisen. Die Ventileinheit 12 weist hinsichtlich der Ausdehnungen in die drei senkrecht zueinander ausgerichteten Raumrichtungen Länge, Breite, Höhe deutliche Unterschiede auf. Vorliegend sind die Ventileinheiten 12 derart ausgebildet, dass sie eine geringe Breite aufweisen, die gleich oder geringfügig kleiner als die in Stapelrichtung 3 zu messende Breite des Kanalkörpers 11 gewählt ist. Hierdurch ist die Aneinanderreihung der mit den Ventileinheiten 12 versehenen Ventilmodule 2 gemäß der Darstellungen der Figuren 1 und 2 möglich, ohne dass Ventileinheiten 12 benachbarter Ventilmodule 2 miteinander kollidieren.Due to the design of the electromagnetic actuator 76 with two coil formers 80, 81 magnetically coupled to each other by the iron yoke 79, the valve unit 12, which in the embodiment is realized in the 2/2-way valves 41, 42, 45, 46, may have an elongate shape , The valve unit 12 has in terms of expansions in the three aligned perpendicular to each other Spatial directions length, width, height significant differences. In the present case, the valve units 12 are formed such that they have a small width which is equal to or slightly smaller than the width to be measured in the stacking direction 3 of the channel body 11 is selected. As a result, the juxtaposition of the provided with the valve units 12 valve modules 2 according to the representations of FIGS. 1 and 2 possible without valve units 12 of adjacent valve modules 2 collide with each other.
