Die Erfindung betrifft ein Baukastensystem mit mindestens einem Hauptventilblock, mit mindestens zwei Gruppen an Verbindungsleitungen, die an einer Stelle über eine Verbindungsleitung der einen Gruppe allesamt fluidführend miteinander verbunden sind gemäß der Merkmalsausgestaltung des Oberbegriffes des Patentanspruches 1.The invention relates to a modular system having at least one main valve block, with at least two groups of connecting lines, which are all fluidly connected to one another via a connecting line of a group according to the feature configuration of the preamble of claim 1.

Durch die DE-OS 27 50 035 ist ein hydraulischer Baukasten bekannt bestehend aus kleinen höhen- und flächenverkettbaren hydraulischen Elementen mit druck- und/oder mengenverändernden bzw. verteilenden oder steuernden Funktionen und einem Grundblock, wobei das Anschlußbild der Elemente und des Grundblocks punktsymmetrisch gestaltet und durch zwei Anschlußbohrungen und zwei Befestigungsbohrungen gebildet ist und wobei ferner die Elemente und der Grundblock in vorbestimmter Zuordnung und/oder Folge sowie um die Längsachse um 180° verdreht aufeinander angeordnet sind. Dergestalt ergibt sich ein platzsparender Aufbau für die genannten miteinander verkettbaren hydraulischen Elemente.By the DE-OS 27 50 035 is a hydraulic kit known consisting of small height and flächenverkettbaren hydraulic elements with pressure and / or quantity-changing or controlling or controlling functions and a basic block, the connection pattern of the elements and the basic block is point-symmetrical and formed by two terminal holes and two mounting holes and further wherein the elements and the base block are arranged in a predetermined assignment and / or sequence and about the longitudinal axis rotated by 180 ° to each other. In this way, a space-saving construction results for the said hydraulic elements which can be linked together.

Durch die EP 0 854 982 B1 ist ein modular aufgebauter Hauptventilblock bekannt eines vorgesteuerten Sitz- und/oder Kolbenventile aufweisenden Ventilsystems, der sowohl eine genormte Anschlußschnittstelle als auch eine Pilotventilschnittstelle zur Aufnahme eines Pilotventils aufweist und der eine Pump-, eine Tank-, eine erste Arbeitsleitung, eine zweite Arbeitsleitung, eine erste Steuerleitung und eine zweite Steuerleitung aufweist und in dem vier Ventilaufnahmen zur Aufnahme von je einer Ventileinheit angeordnet sind. Die dahingehende Lösung hat sich insbesondere für die Cartridge-Technik als geeignet erwiesen, bei der für den jeweiligen Anwendungsfall geeignete Ventileinheiten (Cartridges) an den Hauptventilblock angebaut werden.By the EP 0 854 982 B1 is a modular main valve block known from a pilot operated seat and / or piston valves having valve system having both a standardized port interface and a pilot valve interface for receiving a pilot valve and a pump, a tank, a first working line, a second working line, a first control line and a second control line and in which four valve receptacles are arranged for receiving a respective valve unit. The pertinent solution has proved to be particularly suitable for the cartridge technology, in which suitable for the particular application valve units (cartridges) are attached to the main valve block.

Durch die DE 199 21 436 A1 ist eine Hydraulikanlage zur Versorgung eines Hydraulikverbrauchers bei Kraftfahrzeugen bekannt, mit der der Aufwand zur Ausbildung unterschiedlicher Varianten reduziert ist. Bei der bekannten Hydraulikanlage ist ein Druck- oder Hydrauliktank vorgesehen, in dem ein Hydraulikmittel bevorratet und mit Druck beaufschlagbar ist, wobei als Trägergehäuse ausgebildet sämtliche Bestandteile der Hydraulikanlage derart anbringbar sind, dass diese eine komplett montierbare Montageeinheit bilden. Des weiteren weist die bekannte Lösung eine Hydraulikmittel-Pumpe auf, die das Hydraulikmittel aus dem Drucktank oder in den Drucktank fördert, wobei ferner ein Elektromotor vorgesehen ist zum Antrieb der Hydraulikmittel-Pumpe sowie ein Steuergerät, das eine Steuerung zur Betätigung des Elektromotors enthält. Dabei ist ein Druckspeicher, der Druck in Form potentieller Energie speichert und das Hydraulikmittel des Drucktanks mit diesem Druck beaufschlagt sowie das Pumpenmodul im inneren des Drucktanks und die sonstigen Module außen am Drucktank angebracht. Mit der dahingehend bekannten Lösung einer Hydraulikanlage ist ein modular aufgebautes Baukastensystem realisiert, mit dem sich eine Vielzahl an Aufgaben lösen läßt.By the DE 199 21 436 A1 is a hydraulic system for supplying a hydraulic consumer in motor vehicles is known, with the effort to form different variants is reduced. In the known hydraulic system, a pressure or hydraulic tank is provided in which a hydraulic means stored and can be acted upon with pressure, wherein formed as a carrier housing all components of the hydraulic system are attachable such that they form a completely mountable mounting unit. Furthermore, the known solution to a hydraulic fluid pump, which promotes the hydraulic fluid from the pressure tank or in the pressure tank, further comprising an electric motor is provided for driving the hydraulic fluid pump and a control unit which includes a controller for actuating the electric motor. In this case, a pressure accumulator which stores pressure in the form of potential energy and pressurizes the hydraulic fluid of the pressure tank and the pump module in the interior of the pressure tank and the other modules attached to the outside of the pressure tank. With the well-known solution of a hydraulic system, a modular construction kit system is realized with which a variety of tasks can be solved.

Durch die US 2002/0038671 A1 ist eine Ventiblocklösung bekannt mit einem Hauptventilblock, der die Möglichkeit eröffnet, eine Vielzahl von hydraulischen Anschlußleitungen fluidführend miteinander in Verbindung zu bringen, wobei standardisierte Einheitsventile zur Ansteuerung des jeweiligen Fluidweges dienen können. Da die Gewindeanschlüsse für die Fluidleitungen im Hauptventilblock gleichfalls standardisiert sind, lassen sich insoweit korrespondierende Hydraulikanschlüsse anbringen und die genannten Standardventile können je nach Anwendungsfall in die standardisierten Gewinde der Verbindungsleitungen innerhalb des Hauptventilblockes eingeschraubt werden. Ein Baukastensystem im Sinne, dass an den Hauptventilblock eine Vielzahl verschiedenster Komponenten, wie Manometer, Hydropumpen, Kühler- und/oder Filtereinheiten, Hydrospeicher etc., in funktionsfähiger Weise angeschlossen werden können, ist durch diese bekannte Lösung nicht aufgezeigt. Mithin verfügt in Übereinstimmung mit dem Oberbegriff des Patentanspruches 1 die bekannte Ventilblocklösung über zwei Gruppen an Verbindungsleitungen, die an mindestens einer Stelle über eine Verbindungsleitung der einen Gruppe allesamt fluidführend miteinander verbunden sind, wobei mindestens zwei weitere Verbindungsleitungen dieser einen Gruppe jeweils mit einer zuordenbaren Verbindungsleitung der anderen Gruppe verbunden sind und wobei für den Einsatz vorgebbarer Ventilkomponenten in Form der Standardventileinsätze gleicher Bauart mindestens drei Platzhalter in die Verbindungsleitung der anderen Gruppe geschaltet sind.By the US 2002/0038671 A1 is a Ventiblocklösung known with a main valve block, which opens the possibility of a plurality of hydraulic connection lines fluidly connected to each other bring, with standardized unit valves can serve to control the respective fluid path. Since the threaded connections for the fluid lines in the main valve block are also standardized, so far corresponding hydraulic connections can be installed and said standard valves can be screwed depending on the application in the standardized thread of the connecting lines within the main valve block. A modular system in the sense that on the main valve block a variety of different components, such as pressure gauges, hydraulic pumps, radiator and / or filter units, hydraulic accumulators, etc., can be connected in a functional manner is not shown by this known solution. Thus, in accordance with the preamble of claim 1, the known valve block solution via two groups of connecting lines, which are connected at least one point via a connecting line of a group all fluid carrying together, wherein at least two further connecting lines of this one group each with an assignable connecting line of are connected to another group and wherein for the use of predeterminable valve components in the form of standard valve inserts of the same type at least three placeholders are connected in the connecting line of the other group.

Zusammenfassend bleibt jedoch festzuhalten, dass die bekannten Lösungen nicht geeignet sind, den zusehends komplexer werdenden Systemanforderungen an Hydraulikanlagen gerecht zu werden. Der Steuerungsaufwand für dahingehende hydraulische Steuerungen nebst den zuordenbaren Anlagenteilen ist derart gewachsen, dass man heute in Abkehr von modular aufbauenden Konzepten verstärkt Einzellösungen sucht, weil die bekannten Module oder Komponenten zur Komplementierung eines hydraulischen Baukastens regelmäßig nicht ausreichen, um dem dahingehend gestiegenen System- und Steueraufwand gerecht zu werden.In summary, however, it should be noted that the known solutions are not suitable to meet the increasingly complex system requirements for hydraulic systems. The control effort for pertinent hydraulic controls together with the assignable parts of the system has grown so much that today, in a move away from modular concepts, it is increasingly looking for individual solutions because the known modules or components for complementing a hydraulic system Modular system is not sufficient to meet the increased system and tax expenditure.

Ausgehend von diesem Stand der Technik liegt daher der Erfindung die Aufgabe zugrunde, die bekannten Lösungen dahingehend weiter zu verbessern, dass ein Baukastensystem geschaffen ist, das sich kostengünstig und in platzsparender Weise realisieren läßt, das funktionssicher im Gebrauch ist und das den gestiegenen Anforderungen an die Komplexität an möglichen Aufgabenstellungen für ein dahingehendes hydraulisches Gesamtsystem gerecht wird. Eine dahingehende Aufgabe löst ein Baukastensystem mit den Merkmalen des Patentanspruches 1 in seiner Gesamtheit.Based on this state of the art, the invention has the object to further improve the known solutions to the effect that a modular system is created, which can be implemented inexpensively and in a space-saving manner that is reliable in use and that the increased demands on the Complexity of possible tasks for a pertinent overall hydraulic system. A pertinent task solves a modular system with the features of claim 1 in its entirety.

Dadurch, dass gemäß dem kennzeichnenden Teil des Patentanspruches 1 mindestens zwei weitere Platzhalter zwischen eine gemeinsame Verbindungsleitung der anderen Gruppe und jeweils einer anderen zuordenbaren Verbindungsleitung dieser anderen Gruppe geschaltet sind, ist ausgehend von dem Hauptventilblock als Hauptkomponente des angesprochenen Baukastensystems eine Platzhalterlösung geschaffen, die es erlaubt, in Abhängigkeit der jeweiligen Systemaufgabe und in Abhängigkeit der ansonsten anzubauenden Komponenten des Baukastensystems einzelne Ventilkomponenten für jeden Platzhalter zu benutzen, die dann insgesamt auch mit den anderen Komponenten die jeweils gesetzte Systemaufgabe lösen. Die angesprochenen Platzhalter bilden in Verbindung mit den angesprochenen Verbindungsleitungen für den Hauptventilblock eine Art Matrixaufbau aus mit Quer- und Längsreihen, wobei die erfindungsgemäße Platzhalterlösung nebst dem matrixartigen Verbindungsaufbau über die Verbindungsleitungen es ermöglicht, einer ausgesprochene Vielzahl an Systemaufgaben gerecht zu werden. Die dahingehende Lösung ist auch platzsparend in ihrem Aufbau; somit kostengünstig zu realisieren und im übrigen funktionssicher in der Anwendung. Einmal im Einsatz befindliche Hautventilblöcke als Grundsystem für den jeweiligen hydraulischen Baukasten lassen sich darüber hinaus vor Ort leicht umbauen, sofern geänderte Systemaufgaben dies notwendig erscheinen lassen.Characterized in that, according to the characterizing part of claim 1, at least two further placeholders are connected between a common connection line of the other group and each other assignable connection line of this other group, starting from the main valve block as a main component of the mentioned modular system a placeholder solution is created, which allows , depending on the respective system task and depending on the components of the modular system otherwise to be installed to individual valve components for each placeholder use, which then solve the system task set in total with the other components. The mentioned placeholder form in connection with the mentioned connecting lines for the main valve block a kind of matrix structure with transverse and longitudinal rows, wherein the placeholder solution according to the invention together with the matrix-like connection structure via the connecting lines makes it possible to meet a very wide variety of system tasks. The pertinent solution is also space-saving in its construction; thus cost-effective to implement and otherwise functionally reliable in the application. In addition, skin valve blocks once in use as the basic system for the respective hydraulic modular system can be easily converted on site, provided that changed system tasks make this appear necessary.

Vorzugsweise ist des weiteren vorgesehen, dass mindestens ein Platzhalter von einer Ventilkomponente unbesetzt bleibt oder den jeweiligen fluidführenden Weg einer oder mehrerer Verbindungsleitungen der einen oder der anderen Gruppe sperrt oder einen fluidführenden Weg zwischen Verbindungsleitungen der anderen Gruppe bildet. Während die anderen Platzhalter demgemäß mit Ventilkomponenten beaufschlagt sind, erlaubt der dahingehend frei gebliebene Platzhalter eine sinnfällige Fluidsteuerung innerhalb des Hauptventilblockes in Abhängigkeit von der Systemaufgabe.Preferably, it is further provided that at least one placeholder remains unoccupied by a valve component or blocks the respective fluid-carrying path of one or more connecting lines of one or the other group or forms a fluid-carrying path between connecting lines of the other group. While the other placeholders are accordingly loaded with valve components, the vacant spaceholder permits a meaningful fluid control within the main valve block as a function of the system task.

Bei einer bevorzugten Ausführungsform des erfindungsgemäßen Baukastensystems weist der Hauptventilblock außenumfangsseitig Anschlußstellen auf zum wahlweisen oder teilweise gemeinsamen Anschließen von weiteren Komponenten, wie Manometern, Hydropumpen, Kühler- und/oder Filtereinheiten, Hydrospeicher, weiteren Ventilkomponenten, Hydrauliktanks, elektrischen und elektronischen Steuerkomponenten einschließlich Sensoren und Schaltmagneten, sowie von mindestens einem Zwischen- oder Nebenanschlußblock. Da somit nicht nur integrale Ventilkomponenten innerhalb des Hauptventilblocks nutzbar sind, sondern weitergehende, außenumfangsseitig angeordnete Komponenten am Hauptventilblock anschließbar sind, ist auch insoweit die Varianz des Systems deutlich erhöht bei dennoch kompakt aufbauendem Systemteil-Hauptventilblock. Vorzugsweise ist dabei weiter vorgesehen, dass der Zwischen- oder Nebenanschlußblock mit zusätzlichen Platzhaltern versehen ist, wobei als Ventilkomponente für die Platzhalter solche wie Druckbegrenzungsventile, Rückschlagventile, ansteuerbare Schaltventile etc. zur Anwendung gebracht werden können, deren Auswahl sich an der jeweiligen Systemaufgabe vorrangig orientiert.In a preferred embodiment of the modular system according to the invention, the main valve block on the outer peripheral side connection points for selectively or partially common connection of other components such as manometers, hydraulic pumps, radiator and / or filter units, hydraulic accumulator, other valve components, hydraulic tanks, electrical and electronic control components including sensors and solenoids, as well as at least one intermediate or secondary terminal block. Since not only integral valve components within the main valve block can be used, but more extensive components arranged on the outer peripheral side can also be connected to the main valve block, the variance of the system is also markedly increased, despite the fact that the system part main valve block is still compact. Preferably, it is further provided that the intermediate or secondary connection block is provided with additional placeholders, such as pressure relief valves, check valves, controllable switching valves, etc. can be used as a valve component for the placeholder whose selection is based primarily on the respective system task.

Bei einer besonders bevorzugen Ausführungsform des erfindungsgemäßen Baukastensystems ist der jeweilige Hydrauliktank als Modul aufgebaut und aus einer Vielzahl an Hydrauliktanks auswählbar, die über genannte Anschlußstellen verfügen zwecks Komplementierung mit den anderen Komponenten des Baukastens und die in vorgebbaren Stufen auswählbar unterschiedliche Tank-Volumina aufweisen. Als besonders vorteilhaft hat es sich dabei erwiesen, die Hydrauliktanks in den Größen 25, 50, 100, 150 sowie 200 Liter vorzusehen und die Hydrauliktanks sind derart konzipiert, dass sie ineinander und gleichzeitig auf eine halbe EURO-Palette zu Transportzwecken passen.In a particularly preferred embodiment of the modular system according to the invention, the respective hydraulic tank is constructed as a module and selectable from a plurality of hydraulic tanks, which have said connection points for complementation with the other components of the kit and the selectable in predetermined levels tank volumes have. It has proven to be particularly advantageous to provide the hydraulic tanks in the sizes 25, 50, 100, 150 and 200 liters and the hydraulic tanks are designed so that they fit into one another and at the same time to half EURO pallet for transport purposes.

Das Baukastensystem-Konzept erlaubt zum einen eine komplette Lieferung an Systemkomponenten, insbesondere von Hydrauliktank, Hydropumpe nebst zugehörigem Elektromotor, Ventilblöcke mit Druck-, Richtungs- und Flow-Ventilen unter Einbezug von Filtereinheiten, Hydrospeichern, Öl-, Luft-Kühlern nebst Zubehörtellen. Im Hinblick auf den modularen Aufbau bleibt es innerhalb des Ermessensspielraums des Anwenders, ob er alle Komponenten von nur einem Hersteller beziehen möchte oder gegebenenfalls sich auch flankierend für Komponenten anderer Hersteller entscheidet. Mit dem erfindungsgemäßen Baukastensystem ist somit eine Lösung geschaffen, die weitgehend anwenderspezifisch die Komplementierung von Gesamt-Hydraulikanlagen ermöglicht.The modular system concept allows for a complete delivery of system components, in particular hydraulic tank, hydraulic pump and associated electric motor, valve blocks with pressure, directional and flow valves with inclusion of filter units, hydraulic accumulators, oil, air coolers and accessories. With regard to the modular design, it remains within the discretion of the user, whether he is all Would like to obtain components from only one manufacturer or optionally also flanking decides for components from other manufacturers. With the modular system according to the invention, a solution is thus created which allows largely user-specific complementation of overall hydraulic systems.

Im folgenden wird das erfindungsgemäße Baukastensystem anhand von Ausführungsbeispielen nach der Zeichnung näher erläutert. Dabei zeigen in prinzipieller und nicht maßstäblicher Darstellung die

Fig.1 bis 4
in Form von Schaltplänen vier verschiedene Systemlösungen;

Die Fig. 1 zeigt in chaltungstechnischer Hinsicht einen Hauptventilblock 10 mit mindestens zwei Gruppen 12,14 an Verbindungsleitungen, die an einer Stelle 16 über eine Verbindungsleitung der einen Gruppe 12 allesamt fluidführend miteinander verbunden sind, wobei mindestens zwei weitere Verbindungsleitungen dieser einen Gruppe 12 jeweils mit einer zuordenbaren Verbindungsleitung der anderen Gruppe 14 verbunden sind, wobei für den Einsatz vorgebbarer Ventilkomponenten mindestens drei Platzhalter 18 in die Verbindungsleitungen der anderen Gruppe 14 geschaltet sind und wobei mindestens zwei weitere Platzhalter 20 zwischen eine gemeinsame Verbindungsleitung 14a der anderen Gruppe 14 und jeweils einer anderen zuordenbaren Verbindungsleitung 14b dieser anderen Gruppe 14 geschaltet sind.The Fig. 1 shows in terms of circuit engineering, a main valve block 10 with at least two groups 12,14 on connecting lines, which are all connected at one point 16 via a connecting line of a group 12 fluidly interconnected, wherein at least two further connecting lines of this one group 12 each with an assignable connecting line of are connected to other group 14, wherein for the use of predeterminable valve components at least three placeholders 18 are connected in the connecting lines of the other group 14 and wherein at least two further placeholder 20 between a common Connection line 14a of the other group 14 and a respective other assignable connection line 14b of this other group 14 are connected.

Ausgehend von dem Grundkonzept nach der Fig.1 zeigen die Fig.2 bis 4 nunmehr gleichfalls in der Art von Schaltplänen verschiedene Ausführungsformen an hydraulischen Lösungen, bei denen die Platzhalter 18,20 durch Ventilkomponenten besetzt sind. So weist die schaltungstechnische Lösung nach der Fig.2 für die beiden in Blickrichtung auf die Figur gesehen rechten Platzhalter 18 je ein Druckbegrenzungsventil 22 auf und auf der linken Bildhälfte ist der Platzhalter 18 mit einem Rückschlagventil 24 besetzt. Der rechte Platzhalter 20 ist mit einer einstellbaren Drossel 26 versehen und der ganz linke weitere Platzhalter 20 erlaubt einen fluidführenden Weg 28 zwischen Verbindungsleitungen 14,14b der dahingehenden anderen Gruppe.Starting from the basic concept after the Fig.1 show the 2 to 4 now also in the form of schematics different embodiments of hydraulic solutions in which the placeholders 18,20 are occupied by valve components. Thus, the circuit technology solution according to the Fig.2 for the two in the direction of the figure seen right placeholders 18 each have a pressure relief valve 22 and on the left half of the blank 18 is occupied by a check valve 24. The right placeholder 20 is provided with an adjustable throttle 26 and the leftmost further placeholder 20 allows a fluid carrying path 28 between connecting lines 14,14b of the other group.

Bei einer entsprechend geänderten Ausführungsform nach der Fig.3 können die dahingehenden Platzhalter 20 auch mit einer den Fluidweg 28 sperrenden Einrichtung 30 versehen sein oder bei einer nicht näher dargestellten Ausführungsform kann ein dahingehender Platzhalter 18, vorzugsweise jedoch 20, auch vollständig unbesetzt bleiben, je nachdem, welches hydraulische Gesamtsystem man realisieren möchte.In a correspondingly modified embodiment according to the Figure 3 can the pertinent placeholder 20 also be provided with a fluid path 28 blocking device 30 or in an embodiment not shown a pertinent placeholder 18, but preferably 20, remain completely unoccupied, depending on which overall hydraulic system you want to realize.

Des weiteren weist der Hauptventilblock außenumfangsseitig Anschlußstellen 32 auf (s. Fig.1) zum wahlweisen oder teilweise gemeinsamen Anschließen von weiteren Komponenten, wie Manometern 34, Hydropumpen 36 mit Elektroantrieb 60, Kühlereinheiten 38 (vgl. Fig.5), Filtereinheiten 40, Hydrospeichern 42, weiteren Ventilkomponenten 44, Hydrauliktanks 46, elektrischen und elektronischen Steuerkomponenten 48 (s. Fig.2) sowie von mindestens einem Zwischen- oder Nebenanschlußblock 50 (s. Fig.4). Wie die einzelnen Schaltpläne zeigen, kann der jeweilige Platzhalter 18,20 Ventilkomponenten aufweisen, wie Druckbegrenzungsventile 22, Rückschlagventile 24, Drosseln 26 oder Blenden sowie Schaltventile 52, beispielsweise in Form des 4/3-Wege-Ventils nach der Fig.3, oder in der Art von Druckwaagen 54 (vgl. Fig.4).Furthermore, the main valve block on the outer peripheral side connection points 32 (s. Fig.1 ) for selectively or partially connecting other components, such as manometers 34, hydraulic pumps 36 with electric drive 60, cooler units 38 (see. Figure 5 ), Filter units 40, hydraulic accumulators 42, further valve components 44, hydraulic tanks 46, electrical and electronic control components 48 (see FIG. Fig.2 ) and at least one intermediate or secondary connection block 50 (s. Figure 4 ).

Figure 4 ).

Wie insbesondere die Fig. 4 zeigt, ist dort der Hauptventilblock 10 mit einem Zwischen- oder Nebenanschlußblock 50 kombiniert, der auf einer seiner Stirnseiten entsprechend angebracht ist. Der dahingehende Zwischen- oder Nebenanschlußblock 50 ist mit zusätzlichen Platzhaltern 56 versehen, die wiederum mit entsprechenden Ventilkomponenten, wie bereits erläutert, in Abhängigkeit der Lösung der jeweiligen Systemaufgabe belegbar sind. Für einen funktionssicheren und kompakten Aufbau hat es sich darüber hinaus als vorteilhaft erwiesen, wie dies die Grundschaltung nach der Fig.1 zeigt, die jeweiligen Platzhalter 18,20 des Hauptventilblockes 10 in Funktionsgruppen zusammenzufassen, und zwar einmal in einer Zweier-Gruppe und einmal in einer Dreier-Gruppe, die räumlich von Verbindungsleitungen der einen Gruppe 12 getrennt sind. Die in Blickrichtung auf die Fig. 1 dargestellte linke Funktionsgruppe besteht dabei einmal aus einem Platzhalter 18 sowie einem weiteren Platzhalter 20 und die reche Funktionsgruppe aus zwei Platzhaltern 18 sowie einem weiteren Platzhalter 20. Bei einer anderen, nicht näher dargestellten Ausführungsform werden die Schaltungen vorzugsweise mit sechs Stück an Platzhaltern realisiert und eine Aufteilung nach ganzzahligen Vielfachem an Platzhaltern vorgenommen.How the particular Fig. 4 shows, there is the main valve block 10 is combined with an intermediate or secondary terminal block 50 which is mounted on one of its end faces accordingly. The pertinent intermediate or secondary connection block 50 is provided with additional spacers 56, which in turn can be assigned to corresponding valve components, as already explained, as a function of the solution of the respective system task. For a functionally reliable and compact design, it has also proved to be advantageous, as the basic circuit according to the Fig.1 shows the respective placeholder 18, 20 of the main valve block 10 in functional groups summarized, once in a two-party group and once in a group of three, which are spatially separated from connecting lines of a group 12. The looking in the direction of Fig. 1 shown left function group consists in this case of a placeholder 18 and another placeholder 20 and the right function group of two placeholders 18 and another placeholder 20. In another, not shown embodiment, the circuits are preferably realized with six pieces of placeholders and a division made after integer multiple placeholders.
