Description

Luftzuführblock für eine Webmaschine Air supply block for a weaving machine
Die Erfindung betrifft einen Luftzuführblock für eine Webmaschine mit zwischen Eingang und Ausgang angeordneten Kanälen und mittels Ventilantrieben schaltbaren und/oder einstellbaren Ventilen.The invention relates to an air supply block for a weaving machine with channels arranged between the inlet and outlet and valves which can be switched and / or adjusted by means of valve drives.
Ein Luftzuführblock der eingangs genannten Art ist aus der WO 97/29231 bekannt. Der Luftzuführblock ist zwischen einer Druckluftzuführeinrichtung und einem Paar von Hauptblasdüsen angeordnet, die einen Schußfaden in ein Webfach eintragen. Der bekannte Luftzuführblock enthält einen an die Druckluftzufuhr angeschlossenen Eingang und einen an das Paar Haupt- blasdüsen angeschlossenen Ausgang. Eingang und Ausgang sind mittels im Luftzuführblock vorhandenen Kanälen miteinander verbunden, wobei in den Luftzuführblock ein schaltbares Schließventil und ein einstellbares Drosselventil integriert sind. Wenn eine Webmaschine eine größere Anzahl unterschiedlicher Schußfäden verarbeiten soll, so ist eine entsprechend große Anzahl von Paaren von Hauptblasdüsen und auch eine entsprechend große Anzahl an Luftzuführblöcken erforderlich.An air supply block of the type mentioned is known from WO 97/29231. The air supply block is arranged between a compressed air supply device and a pair of main blowing nozzles which insert a weft thread into a shed. The known air supply block contains an inlet connected to the compressed air supply and an outlet connected to the pair of main blowing nozzles. The inlet and outlet are connected to each other by means of channels in the air supply block, a switchable closing valve and an adjustable throttle valve being integrated in the air supply block. If a weaving machine is to process a larger number of different weft threads, a correspondingly large number of pairs of main blowing nozzles and also a correspondingly large number of air supply blocks are required.
Der Erfindung liegt die Aufgabe zugrunde, einen Luftzuführblock der eingangs genannten Art so auszubilden, daß relativ viele Hauptblasdüsen mit Druckluft versorgt werden können, ohne daß für die Druckluftversorgung ein sehr großer Bauraum erforderlich ist.The invention has for its object to design an air supply block of the type mentioned in such a way that a relatively large number of main blowing nozzles can be supplied with compressed air, without requiring a very large installation space for the compressed air supply.
Diese Aufgabe wird dadurch gelöst, daß an einer Längsseite eines im wesentlichen quaderformigen Grundkörpers zwei Ausgänge vorgesehen sind, denen jeweils eigene Ventile zugeordnet sind.This object is achieved in that two outputs are provided on a longitudinal side of an essentially cuboid base body, each of which is assigned its own valve.
Die Erfindung bietet den Vorteil, daß mittels eines Luftzuführblockes zwei Sätze von Hauptblasdüsen mit Druckluft versorgbar sind, so daß der benötigte Bauraum relativ gering ist. Derartige Luftzuführblöcke eignen sich besonders gut für die Verwendung in Luftdüsenwebmaschinen, bei denen mehrere unterschiedliche Schußfäden verarbeitet werden.The invention offers the advantage that two sets of main blowing nozzles can be supplied with compressed air by means of an air supply block, so that the installation space required is relatively small. Such air supply blocks are particularly well suited for use in air jet looms in which several different weft threads are processed.
In weiterer Ausgestaltung der Erfindung wird vorgesehen, daß der Grundkörper auf zwei einander gegenüberliegenden Längsseiten frei von Eingängen, Ausgängen und Ventilantrieben ist. Dadurch ist es möglich, die Luftzuführblöcke dicht nebeneinander zu montieren, so daß der Platzbedarf weiter verringert werden kann.In a further embodiment of the invention it is provided that the base body is free of inputs, outputs and valve drives on two opposite longitudinal sides. This makes it possible to mount the air supply blocks close together, so that the space requirement can be further reduced.
In weiterer Ausgestaltung der Erfindung wird vorgesehen, daß der oder die Eingänge, die Kanäle und die Ausgänge im wesentlichen in einer gemeinsamen Längsebene des Grundkörpers angeordnet sind. Auf diese Weise läßt sich die Breite des Grundkörpers des Luftzuführblockes in Querrichtung beschränken, so daß dann auf relativ kleinem Raum eine relativ große Anzahl derartiger Luftzuführblöcke untergebracht werden kann.In a further embodiment of the invention it is provided that the input or inputs, the channels and the outputs are arranged essentially in a common longitudinal plane of the base body. In this way, the width of the base body of the air supply block can be limited in the transverse direction, so that a relatively large number of such air supply blocks can then be accommodated in a relatively small space.
Weitere Merkmale und Vorteile der Erfindung, insbesondere bezüglich der Unterbringung der Luftzuführblöcke auf kleinem Raum ergeben sich aus den weiteren Unteransprüchen.Further features and advantages of the invention, in particular with regard to the accommodation of the air supply blocks in a small space, result from the further subclaims.

Die Ventilstößel 18 der Schließventile 14 und 16 liegen jeweils in der Verlängerung des zugehörigen Ausgangs 5 und 6 und verlaufen parallel zueinander. Die einstellbaren Drosselventile 15 und 17 besitzen jeweils eine Spindel 21, die mittels eines Linearmotors 22 axial verstellbar ist. Das Ende 23 der Spindel 21 ragt jeweils in den zugehörigen Kanal 10 und 13. Durch die Einstellung der Position der Spindel 21 in den Kanälen 10 und 13 wird die von dem Eingang 2 zum Ausgang 5 oder von dem Eingang 3 zu dem Ausgang 6 strömende Druckluft gedrosselt, indem der Strömungsquerschnitt des jeweiligen Kanals 10 oder 13 verändert wird, wie dies in der WO 97/29231 beschrieben ist. Die Drosselventile 15 und 17 und insbesondere die Spindeln 21 liegen ebenfalls in der bereits erwähnten Längsebene 24 und sind ebenfalls spiegelsymmetrisch zueinander bezüglich der Mitte 25 angeordnet .The switchable closing valves 14, 16 are each assigned a valve seat 26, which belongs to the channel 9 or 12. A valve tappet 18 is pressed against the valve seat 26 by means of a spring 19 in order to shut off the connection between an inlet 2 or 3 and an outlet 5 or 6. An electromagnet, which is assigned to the valve tappet 18 and lifts off the valve seat 26 in order to open the valve, serves as the valve drive 20. The valve lifters 18 of the closing valves 14 and 16 each lie in the extension of the associated outlet 5 and 6 and run parallel to one another. The adjustable throttle valves 15 and 17 each have a spindle 21 which is axially adjustable by means of a linear motor 22. The end 23 of the spindle 21 protrudes into the associated channels 10 and 13. By adjusting the position of the spindle 21 in the channels 10 and 13, the compressed air flowing from the inlet 2 to the outlet 5 or from the inlet 3 to the outlet 6 becomes throttled by changing the flow cross-section of the respective channel 10 or 13, as described in WO 97/29231. The throttle valves 15 and 17 and in particular the spindles 21 are also in the longitudinal plane 24 already mentioned and are also arranged mirror-symmetrically to one another with respect to the center 25.
An dem Gehäuse des Linearmotors 22 des Drosselventils 17 ist eine elektrische Steckverbindung 31 angeordnet. Von der Steckverbindung 31 führen elektrische Leitungen 32, 33, 34, 35 zu den Schließventilen 14, 16 und den Drosselventilen 15, 17. An die Steckverbindung 31 wird ein nicht dargestelltes elektrisches Kabel angeschlossen, das zu einer Steuereinheit der Webmaschine führt . Die Verwendung nur einer Steckverbindung 31 für beide Schließventile 14, 16 und beide Drosselventile 15, 17 ist für die Montage des Luftzuführblocks 1 zusammen mit den zugehörigen Teilen auf einer Webmaschine und für die Anbringung der erforderlichen elektrischen Anschlüsse von Vorteil. Die elektrischen Leitungen 32, 33 und 34 sind in einer Längsnut 38 verlegt, die in der die Oberseite bildenden Längsseite 7 vorgesehen ist. Die Leitungen 32 und 33 sind jeweils durch eine Bohrung 36 und 37 des Luftzuführblocks zu den Ventilantrieben 20 der Schaltventile 14, 16 geführt.An electrical plug connection 31 is arranged on the housing of the linear motor 22 of the throttle valve 17. Electrical lines 32, 33, 34, 35 lead from the plug connection 31 to the closing valves 14, 16 and the throttle valves 15, 17. An electrical cable (not shown) is connected to the plug connection 31 and leads to a control unit of the weaving machine. The use of only one plug connection 31 for both closing valves 14, 16 and both throttle valves 15, 17 is advantageous for mounting the air supply block 1 together with the associated parts on a weaving machine and for making the necessary electrical connections. The electrical lines 32, 33 and 34 are laid in a longitudinal groove 38 which is provided in the longitudinal side 7 forming the upper side. The lines 32 and 33 are each led through a bore 36 and 37 of the air supply block to the valve drives 20 of the switching valves 14, 16.
Wie das in Fig. 1 gezeigt ist, sind auf einem Druckluftbehälter 27 mehrere Luftzuführblöcke 1 jeweils mit Schrauben 28 befestigt. Der Druckluftbehälter 27 ist in seiner Mitte mit einer rinnenartigen Vertiefung versehen, in welche die Ventilantriebe 20 der Schaltventile 14 und 16 hineinragen. Seitlich von dieser rinnenartigen Vertiefung besitzt der Druck- luftbehälter 27 mehrere Ausgänge 29, 30, an welche die Eingänge 2, 3 eines Luftzuführblocks 1 anschließen. Bei der dargestellten Ausführungsform sind vier Luftzuführblöcke 1 auf dem Druckluftbehälter 27 montiert. Die Ausgänge 29 und 30, in deren Bereich kein Luftzuführblock 1 angebracht ist, sind mit Verschlußstopfen 43 verschlossen.As shown in FIG. 1, a plurality of air supply blocks 1 are each fastened with screws 28 on a compressed air container 27. The compressed air tank 27 is provided in its center with a groove-like depression into which the valve drives 20 of the switching valves 14 and 16 protrude. To the side of this groove-like depression, the pressure Air tank 27 several outputs 29, 30, to which the inputs 2, 3 of an air supply block 1 connect. In the illustrated embodiment, four air supply blocks 1 are mounted on the compressed air tank 27. The outlets 29 and 30, in the area of which no air supply block 1 is attached, are closed with plugs 43.
Zu den Schließventilen 14, 16 sowie zu den Drosselventilen 15, 17 sind nicht dargestellte Abdichtungsmittel vorgesehen, die ein Ausströmen von Druckluft aus dem Zuführblock 1 in diesem Bereich verhindern. Darüber hinaus sind auch Schrauben 66 vorhanden, um die Ventilantriebe 20, 22 an dem Luftzuführblock 1 zu befestigen. In den gebohrten Kanälen 8 und 11 sind an den nicht benutzten Enden Verschlußstopfen 39, 40 vorgesehen. Die Ausgänge 5, 6 sind mit nur schematisch dargestellten Anschlüssen 41, 42 versehen, die beispielsweise an den Luftzuführblock 1 angeklebt sind. Diese Anschlüsse 41, 42 dienen zum Anschluß von Leitungen, die zu einer oder einem Paar von hintereinander geschalteten Hauptblasdüsen führen. Bei einer abgewandelten Ausführungsform sind Anschlüsse 41, 42 vorgesehen, die mit Gewindeansätzen in entsprechende Gewinde der Ausgänge 5, 6 eingeschraubt sind.Sealing means (not shown) are provided for the closing valves 14, 16 and for the throttle valves 15, 17, which prevent compressed air from flowing out of the supply block 1 in this area. In addition, screws 66 are also provided to fasten the valve drives 20, 22 to the air supply block 1. In the drilled channels 8 and 11, sealing plugs 39, 40 are provided at the unused ends. The outputs 5, 6 are provided with connections 41, 42 which are only shown schematically and which are glued to the air supply block 1, for example. These connections 41, 42 are used to connect lines which lead to one or a pair of main blowing nozzles connected in series. In a modified embodiment, connections 41, 42 are provided, which are screwed into the corresponding threads of the outputs 5, 6 with threaded approaches.
Mit der dargestellten Ausführungsform des Luftzuführblockes 1, bei welchem die Eingänge 2, 3, die Ausgänge 5, 6, die Kanäle 8 bis 13 und die Ventile 14 bis 17 im wesentlichen in der gleichen Längsebene 24 angeordnet sind, läßt sich ein Luftzuführblock 1 mit relativ geringer Breite B in Querrichtung schaffen, so daß eine kompakte Anordnung mehrerer derartiger Luftzuführblöcke 1 möglich ist. Bei der Verwendung üblicher Ventile und Durchmesser ist es möglich, einen Luftzuführblock 1 mit einer Breite B in der Größenordnung von 30 mm auszubilden.With the illustrated embodiment of the air supply block 1, in which the inputs 2, 3, the outputs 5, 6, the channels 8 to 13 and the valves 14 to 17 are arranged essentially in the same longitudinal plane 24, an air supply block 1 with relative Create a smaller width B in the transverse direction, so that a compact arrangement of several such air supply blocks 1 is possible. When using conventional valves and diameters, it is possible to form an air supply block 1 with a width B in the order of 30 mm.
Die Luftzuführblöcke 1 mit zwei Ausgängen 5, 6 und zugehörigen Ventilen sind besonders für die Verwendung bei einer Luftdüsenwebmaschine geeignet. Bei diesen Luftdüsenwebmaschi- nen ist es vorteilhaft, Hauptblasdüsen in gerader Anzahl vorzusehen, da der gleiche Schußfadentyp beispielsweise von zwei Spulen geliefert und somit von zwei Hauptblasdüsen oder zwei Paaren von hintereinandergeschalteten Hauptblasdüsen entsprechend der Offenbarung der WO 97/29231 in ein Webfach eingetragen wird. Falls dennoch eine ungerade Anzahl von Ausgängen gewünscht werden sollte, so ist es ohne weiteres möglich, einen der Ausgänge 5 oder 6 mit einem Verschlußstopfen zu verschließen. Selbstverständlich kann auch die Steuerung so ausgebildet werden, daß das zugehörige Schließventil 14 oder 16 ständig geschlossen bleibt.The air supply blocks 1 with two outlets 5, 6 and associated valves are particularly suitable for use in an air jet loom. With these air jet weaving NEN, it is advantageous to provide an even number of main blowing nozzles, since the same type of weft thread is supplied, for example, by two bobbins and is thus entered into a shed by two main blowing nozzles or two pairs of main blowing nozzles connected in series in accordance with the disclosure of WO 97/29231. If an odd number of outputs is nevertheless desired, it is easily possible to close one of the outputs 5 or 6 with a sealing plug. Of course, the control can also be designed so that the associated closing valve 14 or 16 remains permanently closed.
Die Ausgänge 5 und 6 sind in einem Abstand zueinander angeordnet, der beispielsweise mit dem Abstand von Einläßen zu Hauptblasdüsen übereinstimmt, wie dies beispielsweise in der nicht vorveröffentlichten belgischen Patentanmeldung BE 9700465 korrespondierend zu WO 98/54 385 der Anmelderin offenbart ist . Damit sind die Luftzuführblöcke 1 insbesondere für die Verwendung bei Hauptdüsenvorrichtungen geeignet, wie sie in der genannten belgischen oder der internationalen Patentanmeldung offenbart sind.The outlets 5 and 6 are arranged at a distance from one another which corresponds, for example, to the distance from the inlets to the main blowing nozzles, as is disclosed, for example, in the not previously published Belgian patent application BE 9700465 corresponding to the applicant's WO 98/54 385. The air supply blocks 1 are therefore particularly suitable for use with main nozzle devices, as are disclosed in the Belgian or international patent application mentioned.
Bei der Ausführungsform nach Fig. 4 sind an die Ausgänge 5, 6 Bohrungen 44, 45 angeschlossen, die ihrerseits mit zur Längsseite 7 führenden Bohrungen 46, 47 verbunden sind. Die Bohrungen 44 und 46 liegen bezüglich der Mitte 25 spiegelsymmetrisch zu den Bohrungen 45 und 47. Die Enden der Bohrungen 44 und 45 sind mittels Verschlußstopfen 48, 49 verschlossen. Die Bohrungen 44 bis 47 liegen ebenfalls im wesentlichen in der Längsebene 24 des Luftzuführblocks 1. Die Bohrungen 46 und 47 sind mit Anschlüssen 50, 51 für nicht dargestellte Leitungen versehen, die beispielsweise an den Luftzuführblock 1 angeklebt sind. Über die Bohrungen 46 und 47 kann beispielsweise Druckluft mit relativ geringem Druck zugeführt werden, die dann über die Bohrungen 44 oder 45 zum Ausgang 5 oder 6 strömt. Ähnlich der Ausführungsform nach Fig. 8 kann auch an den Bohrungen 46 oder 47 ein Druckfühler angebracht werden, um den Druck der aus dem Luftzuführblock 1 strömenden Druckluft zu messen.In the embodiment according to FIG. 4, bores 44, 45 are connected to the outputs 5, 6, which in turn are connected to bores 46, 47 leading to the longitudinal side 7. The bores 44 and 46 are mirror-symmetrical to the bores 45 and 47 with respect to the center 25. The ends of the bores 44 and 45 are closed by means of sealing plugs 48, 49. The bores 44 to 47 are also essentially in the longitudinal plane 24 of the air supply block 1. The bores 46 and 47 are provided with connections 50, 51 for lines (not shown) which are glued to the air supply block 1, for example. Compressed air at relatively low pressure can be supplied via the holes 46 and 47, for example, which then flows via the holes 44 or 45 to the outlet 5 or 6. Similar to the embodiment according to FIG. 8, a pressure sensor can also be attached to the bores 46 or 47, to measure the pressure of the compressed air flowing out of the air supply block 1.
In Fig. 5 und 6 ist eine abgewandelte Ausführungsform ähnlich Fig. 4 dargestellt, bei welcher zu dem Ausgang 5 Bohrungen 52, 53 und 54 geführt sind, wobei die Bohrungen 52 und 53 an ihren Enden mit Verschlußstopfen 55, 56 verschlossen sind. Die Bohrungen 52, 53, 54 liegen etwas außerhalb der erwähnten Längsebene 24. Da sie jedoch relativ kleine Abmessungen aufweisen, haben sie nur wenig Einfluß auf die Gesamtbreite B des Luftzuführblocks 1. Diese Breite wird im wesentlichen durch die Ventiltriebe und/oder die Sitze 26 der Schließventile 14, 16 bestimmt.5 and 6 show a modified embodiment similar to FIG. 4, in which bores 52, 53 and 54 are guided to the outlet 5, the bores 52 and 53 being closed at their ends with sealing plugs 55, 56. The bores 52, 53, 54 lie somewhat outside the longitudinal plane 24 mentioned. However, since they have relatively small dimensions, they have little influence on the overall width B of the air supply block 1. This width is essentially determined by the valve drives and / or the seats 26 the closing valves 14, 16 determined.
In Fig. 7 ist ein Ausführungsbeispiel dargestellt, bei welchem der Luftzuführblock 1 zwei Eingänge 2 und 3 und zwei Ausgänge 5 und 6 besitzt, die jeweils über Kanäle 62, 63 und 64, 65 miteinander verbunden sind. Diese Kanäle liegen alle in der gleichen Längsebene 24 des Zuführblockes 1 und sind spiegelsymmetrisch zur Mitte 25 angeordnet. In den Kanälen 62, 64 ist jeweils ein Ventilstiz 59 für eine Ventilspindel 61 vorgesehen, die zusammen mit als Linearmotoren ausgebildeten Ventiltrieben 60 jeweils ein Drosselventil 57, 58 bilden. Diese Drosselventile 57, 58 sind beispielsweise von der Art, wie sie in der WO 96/08668 beschrieben sind.7 shows an exemplary embodiment in which the air supply block 1 has two inputs 2 and 3 and two outputs 5 and 6, which are each connected to one another via channels 62, 63 and 64, 65. These channels are all in the same longitudinal plane 24 of the feed block 1 and are arranged mirror-symmetrically to the center 25. A valve stem 59 is provided in each of the channels 62, 64 for a valve spindle 61, which together with valve drives 60 designed as linear motors each form a throttle valve 57, 58. These throttle valves 57, 58 are, for example, of the type described in WO 96/08668.
Der Luftzuführblock 1 der Fig. 7 ist entsprechend der Ausführungsform nach Fig. 1 auf einem Druckluftbehälter 27 montiert. Die Ausgänge 5 und 6 sind jeweils mit einem Anschluß 41, 42 versehen, an die nicht dargestellte Leitungen angeschlossen sind. Eine derartige Leitung kann beispielsweise an einen Anschluß 50 oder 51 des Luftzuführblockes 1 der Fig. 4 angeschlossen sein, um Druckluft mit geringem, durch das Drosselventil 57 oder 58 gedrosseltem Druck durch diese Leitungen hindurch und die Bohrungen 44, 46 oder 45, 47 zu den Ausgängen 5 oder 6 des Luftzuführblockes 1 der Fig. 4 zu leiten. Der Luftzuführblock 1 nach Fig. 7 ist bei einer ersten Ausführungsform auf dem Druckluftbehälter 27 montiert, auf welchem auch ein oder mehrere Luftzuführblöcke nach Fig. 4 montiert sind. Bei einer abgewandelten Ausführungsform sind der oder die Luftzuführungsblöcke nach Fig. 7 auf einem eigenen Druckluftbehälter montiert, so daß die Luftdrücke in den Druckluftbehältern schon in geeigneter Weise vorgegeben werden können.The air supply block 1 of FIG. 7 is mounted on a compressed air container 27 in accordance with the embodiment of FIG. 1. The outputs 5 and 6 are each provided with a connection 41, 42 to which lines, not shown, are connected. Such a line can be connected, for example, to a connection 50 or 51 of the air supply block 1 of FIG. 4 in order to pass compressed air with a low pressure, which is throttled by the throttle valve 57 or 58, through these lines and the bores 44, 46 or 45, 47 to the Outputs 5 or 6 of the air supply block 1 of Fig. 4 to conduct. In a first embodiment, the air supply block 1 according to FIG. 7 is mounted on the compressed air container 27, on which one or more air supply blocks according to FIG. 4 are also mounted. In a modified embodiment, the one or more air supply blocks according to FIG. 7 are mounted on their own compressed air tank, so that the air pressures in the compressed air tanks can already be predetermined in a suitable manner.
In Fig. 8 ist eine Ausführungsform dargestellt, bei welcher der Luftzuführblock 1 ähnlich wie bei der Ausführungsform nach Fig. 4 Bohrungen 44 bis 47 enthält. An die Bohrunge 46 und 47 ist beispielsweise ein schematisch dargestellter Druckaufnehmer 67 angeschlossen. Dieser Druckaufnehmer ist vorzugsweise über nicht dargestellte elektrische Leitungen mit der Steckverbindung 31 verbunden, so daß die Meßergebnisse an die Steuereinheit der Webmaschine weitergeleitet werden können.FIG. 8 shows an embodiment in which the air supply block 1 contains bores 44 to 47 similar to the embodiment according to FIG. 4. A schematically represented pressure sensor 67 is connected to the bores 46 and 47, for example. This pressure transducer is preferably connected to the plug connection 31 via electrical lines, not shown, so that the measurement results can be forwarded to the control unit of the weaving machine.
In Fig. 9 ist eine Ausführungsform ähnlich Fig. 7 dargestellt, bei welcher die Bauelemente, die Fig. 7 entsprechen, mit den gleichen Bezugsnummern bezeichnet worden sind. Der Luftzuführblock 1 besitzt nur einen Eingang 70 für Druckluft, der in der Längsebene 24 in der Mitte 25 vorgesehen ist. In diesem Bereich ist ein Ausgang 69 eines Druckluftbehälters 71 vorgesehen. Von dem Eingang 70 zweigt ein Kanal 68 nach beiden Seiten ab, der über einen Kanal 63 mit dem Ausgang 5 und über einen Kanal 65 mit dem Ausgang 6 verbunden ist. In dem Kanal 68 sind Ventilsitze 59 angeordnet, denen die Ventilspindeln 61 der Linearmotoren 60 der beiden Drosselventile 57, 58 zugeordnet sind.FIG. 9 shows an embodiment similar to FIG. 7, in which the components that correspond to FIG. 7 have been given the same reference numbers. The air supply block 1 has only one inlet 70 for compressed air, which is provided in the longitudinal plane 24 in the middle 25. An outlet 69 of a compressed air container 71 is provided in this area. A channel 68 branches off from the input 70 on both sides, which is connected to the output 5 via a channel 63 and to the output 6 via a channel 65. Valve seats 59, to which the valve spindles 61 of the linear motors 60 of the two throttle valves 57, 58 are assigned, are arranged in the channel 68.
In Fig. 10 ist eine Ausführungsform dargestellt, die weitgehend der Ausführungsform nach Fig. 2 entspricht, so daß gleiche Teile mit den dort verwendeten Bezugsnummern verzeichnet sind. Der Luftzuführblock 1 enthält jedoch nur einen Eingang 72 für Druckluft, der in der Längsebene 24 des Luftzuführblockes 1 liegt. Dieser Eingang 72 ist an einem in einer Seitenwand der rinnenförmigen Aussparung des Druckluftbehälters 72 befindlichen Ausgang 76 angeschlossen. Der Eingang 72 ist über Kanäle 74, 8, 9 und 10 mit dem Ausgang 5 und über Kanäle 74, 8, 9 , 75, 12 und 13 mit dem Ausgang 6 verbunden. Der Kanal 75 verbindet hierbei die Kanäle 9 und 12. Der Kanal 74 verbindet den Eingang 72 mit dem Kanal 8. Das Ende des Kanals 74 ist mit einem Verschlußstopfen 77 verschlossen.In Fig. 10 an embodiment is shown, which largely corresponds to the embodiment of FIG. 2, so that the same parts are listed with the reference numbers used there. However, the air supply block 1 contains only one entrance 72 for compressed air, which lies in the longitudinal plane 24 of the air supply block 1. This inlet 72 is connected to an outlet 76 located in a side wall of the trough-shaped recess of the compressed air tank 72. The input 72 is connected to the output 5 via channels 74, 8, 9 and 10 and to the output 6 via channels 74, 8, 9, 75, 12 and 13. The channel 75 connects the channels 9 and 12. The channel 74 connects the inlet 72 to the channel 8. The end of the channel 74 is closed with a plug 77.
