Description

Die Erfindung betrifft ein Gehäuse zur Umhüllung einer Düse, insbesondere einer Air-Covering Düse oder einer Lufttexturierdüse, mit mindestens einer einen Fadendurchführungsöffnungsumfang aufweisenden Fadendurchführungsöffnung und einem Gehäusedeckel, der eine Gehäuseöffnung in einer Gehäusebasis abdeckt, wobei der Gehäusedeckel mit Deckelkanten an Gehäusebasiskanten der Gehäusebasis anschließt. Ein derartiges Gehäuse wird als Soundbox bezeichnet und an Garnbearbeitungsmaschinen eingesetzt, insbesondere, um die von der Düse erzeugten Arbeitsgeräusche zu dämmen.The invention relates to a housing for enclosing a nozzle, in particular an air-covering nozzle or a Lufttexturierdüse having at least one Fadendurchführungsöffnungsumfang having Fadendurchführungsöffnung and a housing cover which covers a housing opening in a housing base, wherein the housing cover with lid edges on housing base edges of the housing base connects. Such a housing is referred to as a sound box and used on yarn processing machines, in particular, to dampen the working noise generated by the nozzle.

Garnbearbeitungsmaschinen mit einer Air-Covering Düse (Air-Covering Maschine) werden dazu verwendet, Filamentgarne beständig miteinander zu einem Multikomponentengarn (Air-Covering Garn) zusammen zu führen. Dabei werden als Komponenten mindestens ein Hüllfaden (Effektgarn) mit einem Kernfaden verbunden. Ziel dieses Prozesses ist, möglichst gleichmäßige Verknüpfungsknoten im Multikomponentengarn zu erreichen und so die Komponenten miteinander zu verbinden. Ein Beispiel einer Air-Covering Maschine ist in der US 6,405,519 B1 offenbart. Bei dem Kernfaden handelt es sich meist um ein ein Elastomer enthaltendes Garn. Die Hüllfäden können verschiedene Effektgarne umfassen. Die Filamentgarne, also die Hüllfäden und der Kernfaden, werden über Lieferwerke, z.B. Galetten, einer Air-Covering Düse zugeführt. Nachdem das Multikomponentengarn die Air-Covering Düse durchlaufen hat, wird das Multikomponentengarn von einer Spule, auf die das Multikomponentengarn aufgewickelt wird, aufgenommen. Vor dem Aufspulen kann das Multikomponentengarn nochmals verstreckt, fixiert, geschrumpft und/oder aviviert werden. In der Air-Covering Düse werden die Hüllfäden unter Zuhilfenahme eines Luftstrahls mit dem Kernfaden verbunden. Der Luftstrahl wird dazu mit einer Strahlrichtung, die nicht parallel zu einer Air-Covering Düsenachse der Air-Covering Düse ist, in der Air-Covering Düse geführt. Die Air-Covering Düsenachse der Air-Covering Düse ist durch einen Kanal, in dem die Filamentgarne durch die Air-Covering Düse geführt werden, definiert. Gemäß Stand der Technik wird zumindest der Kernfaden mit einer Fadeneinlaufrichtung in die Air-Covering Düse parallel zur Air-Covering Düsenachse geführt. Idealerweise werden auch die Hüllfäden mit einer Einlaufrichtung zumindest annähernd parallel zu der Air-Covering Düsenachse in Air-Covering Maschinen geführt.Yarn processing machines with an air-covering nozzle are used to consistently combine filament yarns into a multi-component yarn (air-covering yarn). In this case, at least one sheath thread (fancy yarn) are joined as components with a core thread. The aim of this process is to achieve as uniform as possible linking nodes in the multi-component yarn and thus to connect the components with each other. An example of an air-covering machine is in the US Pat. No. 6,405,519 B1 disclosed. The core thread is usually an elastomer-containing yarn. The sheaths may include various fancy yarns. The filament yarns, ie the sheath threads and the core thread, are fed via delivery mechanisms, eg godets, to an air-covering nozzle. After the multicomponent yarn has passed through the air-covering nozzle, the multicomponent yarn is taken up by a spool on which the multicomponent yarn is wound up. Before winding, the multicomponent yarn can be stretched, fixed, shrunk and / or sharpened again. In the air-covering nozzle, the sheaths are connected to the core thread with the help of an air jet. The air jet is guided in the air-covering nozzle with a jet direction that is not parallel to an air-covering nozzle axis of the air-covering nozzle. The air-covering nozzle axis of the air-covering nozzle is defined by a channel in which the filament yarns are passed through the air-covering nozzle. According to the prior art, at least the core thread is guided with a thread entry direction into the air-covering nozzle parallel to the air-covering nozzle axis. Ideally, the Hüllfäden with an inlet direction are at least approximately parallel to the air-covered nozzle axis in air-covered machines.

Weiter sind Garnbearbeitungsmaschinen zur Bearbeitung von Filamentgarnen mit einer Lufttexturierdüse (Lufttexturiermaschine) bekannt. Eine derartige Lufttexturiermaschine ist in der DE 39 09 516 A1 offenbart. Lufttexturiermaschinen werden dazu verwendet, glatte strukturlose Filamentgarne beständig zu kräuseln. Mehrere Vorlagegarne (Kernfäden) können dabei mit Effektgarnen unterschiedlicher Überlieferung zu einem texturierten Garn verarbeitet werden. Im Unterschied zu einer Air-Covering Maschine werden die Filamentgarne in Lufttexturiermaschinen immer mit Fadeneinlaufrichtungen, die einen spitzen Winkel zu einer Lufttexturierdüsenachse bilden, in die Lufttexturierdüse, d.h. in einen die Luftexturierdüsenachse definierenden Kanal der Lufttexturierdüse, durch den die Filamentgarne laufen, geführt. Idealerweise bildet die Einlaufrichtung der Effektgarne mit der Einlaufrichtung der Kernfäden einen rechten Winkel, wobei die Lufttexturierdüsenachse jeweils einen Winkel von 45 Grad mit den Einlaufrichtungen der Effektgarne und der Kernfäden bildet.Further, yarn processing machines for processing filament yarns having an air-texturing nozzle (air-texturing machine) are known. Such an air texturing machine is in DE 39 09 516 A1 disclosed. Air texturing machines are used to consistently curl smooth structureless filament yarns. Several original yarns (core threads) can be processed into a textured yarn using effect yarns of different traditions. In contrast to an air-covering machine, the filament yarns in air-texturing machines are always fed with yarn entry directions forming an acute angle to an air-texturing nozzle axis into the air-texturing nozzle, ie a channel of the air-texturing nozzle through which the filament yarns pass, defining the air-texturing nozzle axis. Ideally, the inlet direction of the effect yarns with the inlet direction of the core threads forms a right angle, wherein the Lufttexturierdüsenachse each forms an angle of 45 degrees with the inlet directions of the effect yarns and the core threads.

Die Düse, also die Air-Covering Düse oder die Lufttexturierdüse einer derartigen Garnbearbeitungsmaschine ist in einem Gehäuse montiert. Das Gehäuse schützt zum einen die Düse, zum anderen dämpft das Gehäuse die Arbeitsgeräusche, die beim Betrieb der Düse erzeugt werden. Bekannte Gehäuse weisen Fadendurchführungsöffnungen in einer Gehäusebasis des Gehäuses und einen Gehäusedeckel auf. Der Gehäusedeckel deckt eine Gehäuseöffnung in der Gehäusebasis ab, wobei der Gehäusedeckel mit Deckelkanten an Gehäusebasiskanten der Gehäusebasis anschließt. Der Deckel ermöglicht es durch die Gehäuseöffnung hindurch Arbeiten an der Düse und/oder zusätzlichen in dem Gehäuse angeordneten Aggregaten durchzuführen. Außerdem müssen die zu verarbeitenden Fäden, also der Kernfaden und die Hüllfäden, durch die Fadendurchführungsöffnungen eingeführt werden, um der Düse zugeführt zu werden. Das Einführen der Fäden ist ebenfalls bei geöffnetem Deckel durchzuführen, da das jeweilige Fadenende dazu in dem Gehäuse aufgegriffen werden muss. Um das Gehäuse möglichst dicht geschlossen zu halten, sind die Fadendurchführungsöffnungen sehr eng ausgelegt. Das Einführen der Fäden stellt daher eine zeitaufwändige Arbeit dar, die unter anderem unter Zuhilfenahme einer speziellen Saugdüse durchgeführt wird. Bei den bekannten Gehäusen ergeben sich deshalb durch das Einführen der Fäden erhebliche Produktionsausfälle.The nozzle, ie the air-covering nozzle or the air-texturing nozzle of such a yarn-processing machine is mounted in a housing. The housing protects the nozzle on the one hand, on the other hand, the housing dampens the working noise that are generated during operation of the nozzle. Known housings have thread passage openings in a housing base of the housing and a housing cover. The housing cover covers a housing opening in the housing base, wherein the housing cover with cover edges on housing base edges of the housing base connects. The lid makes it possible through the housing opening to perform work on the nozzle and / or additional arranged in the housing units. In addition, the threads to be processed, that is, the core thread and the sheath threads, must be inserted through the thread passage openings to be supplied to the nozzle. The insertion of the threads is also carried out with the lid open, since the respective thread end has to be picked up in the housing. In order to keep the housing closed as tight as possible, the thread passage openings are designed very narrow. The insertion of the threads therefore represents a time-consuming work, which is carried out, inter alia, with the aid of a special suction nozzle. In the known cases, therefore, result from the introduction of the threads considerable production losses.

Die JP 2000 303292 A beschreibt ein Gehäuse zur Umhüllung einer Düse mit Fadendurchführungsöffnungen und einem Deckel, wobei die Fadendurchführungsöffnungen teilweise von Deckelkanten ausgebildet sind, so dass ein Faden zwar leicht in die Fadendurchführungsöffnungen eingelegt werden kann, bei geöffnetem Deckel aber auch leicht aus den Fadendurchführungsöffnungen herausfallen kann.The JP 2000 303292 A describes a housing for wrapping a nozzle with Fadendurchführungsöffnungen and a lid, wherein the Fadendurchführungsöffnungen are partially formed by cover edges, so that a thread can be easily inserted into the Fadendurchführungsöffnungen, but can easily fall out of the Fadendurchführungsöffnungen with the lid open.

Der Erfindung liegt die Aufgabe zugrunde, ein Gehäuse zur Umhüllung einer Düse bereitzustellen, das Nachteile des Standes der Technik vermeidet und insbesondere ein rasches Einführen der zu verarbeitenden Fäden ermöglicht.The invention has for its object to provide a housing for wrapping a nozzle, which avoids the disadvantages of the prior art and in particular allows rapid insertion of the threads to be processed.

Diese Aufgabe wird durch das Gehäuse des unabhängigen Anspruchs gelöst. Die abhängigen Ansprüche stellen bevorzugte Ausführungsformen der Erfindung dar.This object is achieved by the housing of the independent claim. The dependent claims represent preferred embodiments of the invention.

Das erfindungsgemäße Gehäuse zur Umhüllung einer Düse, insbesondere einer Air-Covering Düse oder einer Lufttexturierdüse, weist mindestens eine einen Fadendurchführungsöffnungsumfang aufweisende Fadendurchführungsöffnung und einen Gehäusedeckel auf. Der Gehäusedeckel deckt eine Gehäuseöffnung in einer Gehäusebasis ab. Der Gehäusedeckel schließt mit Deckelkanten an Gehäusebasiskanten der Gehäusebasis an. Die Deckelkanten sind also zu den Gehäusebasiskanten komplementär ausgeformt, so dass das Gehäuse bei geschlossenem Gehäusedeckel, mit Ausnahme der Fadendurchführungsöffnungen, dicht abschließt. Die Fadendurchführungsöffnung ist derart an einer der Gehäusebasiskanten angeordnet, dass der Fadendurchführungsöffnungsumfang teilweise von einer der Deckelkanten gebildet wird. Dadurch wird der Umfang der Fadendurchführungsöffnung (Fadendurchführungsöffnungsumfang), wenn der Gehäusedeckel von der Gehäusebasis weggeklappt ist, also wenn die Gehäuseöffnung offen steht, zweigeteilt. Ein Faden muss dann nicht mehr eingeführt werden, sondern kann einfach in, bevorzugt den an der Gehäusebasiskante liegenden Teil des Fadendurchführungsöffnungsumfangs seitlich eingelegt werden. Der Einsatz einer Saugdüse kann dadurch entfallen. Dies führt zu erheblichen Zeitgewinnen und damit zu geringeren Produktionsausfällen.The housing according to the invention for enclosing a nozzle, in particular an air-covering nozzle or an air-texturing nozzle, has at least one thread-passage opening circumference Thread passage opening and a housing cover. The housing cover covers a housing opening in a housing base. The housing cover closes with cover edges on housing base edges of the housing base. The cover edges are thus formed complementary to the housing base edges, so that the housing with the housing cover closed, with the exception of the thread passage openings, tightly seals. The thread passage opening is arranged on one of the housing base edges such that the thread passage opening circumference is partially formed by one of the cover edges. Thereby, when the housing cover is folded away from the housing base, that is, when the housing opening is open, the circumference of the thread passage opening (thread passage opening circumference) is divided into two. A thread then no longer has to be inserted, but can simply be inserted laterally in, preferably the part of the yarn feedthrough opening circumference lying on the housing base edge. The use of a suction nozzle can be omitted. This leads to considerable time gains and thus to lower production losses.

Erfindungsgemäß ist an der, bzw. den Fadendurchführungsöffnungen in dem Gehäuse ein Wolfszahn angeordnet. Ein Wolfszahn ist eine Fadenführungseinrichtung, bei der zwei halbkreisförmige Haken ineinander greifen. Ein Faden kann durch Einhaken in einen der Haken in den Wolfszahn eingeführt werden. Eine Überdeckung der Haken verhindert ein Aushaken des Fadens. Der Wolfszahn hält den seitlich in den an der Gehäusebasiskante liegenden Teil des Fadendurchführungsöffnungsumfangs eingelegten Faden während der Gehäusedeckel aufgeklappt ist in der richtigen Position. Das Einführen, oder im Falle einer Air-Covering Düse das Einlegen, der Fäden in die Düse wird dadurch zusätzlich erleichtert.According to the invention, a wolf tooth is arranged on the or the thread passage openings in the housing. A wolf tooth is a thread guide device in which two semicircular hooks interlock. A thread can be inserted by hooking into one of the hooks in the wolf tooth. Overlapping the hook prevents the thread from unhooking. The wolf tooth holds the thread inserted laterally into the part of the yarn feedthrough opening circumference lying on the housing base edge while the housing cover is unfolded in the correct position. The insertion, or in the case of an air-covering nozzle inserting, the threads in the nozzle is thereby additionally facilitated.

Bevorzugt sind die Fadendurchführungsöffnungen derart relativ zu einer Düsenmontageposition in dem Gehäuse angeordnet, dass die Fadendurchführungsöffnungen in den Fadeneinlaufrichtungen der Düse liegen. Ein Umlenken der Fäden innerhalb des Gehäuses kann dadurch entfallen. Die Fadendurchführungsöffnungen können dabei derart angeordnet sein, dass das erfindungsgemäße Gehäuse sowohl zum Umhüllen einer Air-Covering Düse als auch einer Lufttexturierdüse eingesetzt werden kann. Dazu sind vier oder mehr Fadendurchführungsöffnungen geeignet am Gehäuse anzuordnen. Eine Garnbearbeitungsmaschine mit einem derartigen Gehäuse kann dann flexibel durch Umrüsten mit einer entsprechenden Düse als Air-Covering Maschine oder als Lufttexturiermaschine eingesetzt werden.Preferably, the yarn feedthrough openings are arranged relative to a nozzle mounting position in the housing such that the yarn feedthrough openings lie in the yarn inlet directions of the nozzle. A deflection of the threads within the housing can thereby omitted. The thread passage openings can be arranged such that the housing according to the invention can be used both for wrapping an air-covering nozzle and an air-texturing. For this purpose, four or more thread passage openings are suitable to be arranged on the housing. A yarn processing machine with such a housing can then be used flexibly by retooling with a corresponding nozzle as an air-covering machine or as Lufttexturiermaschine.

Vorteilhaft weist die Gehäusebasis und/oder der Gehäusedeckel im Bereich der Fadendurchführungsöffnung eine Verstärkung auf. Die Fadendurchführungsöffnung bildet dann einen langgestreckten Kanal aus. Dadurch kann ein Schallaustritt aus dem erfindungsgemäßen Gehäuse an der Fadendurchführungsöffnung vermindert werden.Advantageously, the housing base and / or the housing cover has a reinforcement in the region of the thread passage opening. The thread passage opening then forms an elongate channel. Thereby, a sound leakage from the housing according to the invention can be reduced at the thread passage opening.

Um den Prozess auch bei geschlossenem Deckel visuell kontrollieren zu können weist das Gehäuse bevorzugt im Gehäusedeckel ein Sichtfenster auf.In order to be able to visually control the process even with the lid closed, the housing preferably has a viewing window in the housing cover.

Der Gehäusedeckel ist bevorzugt mittels eines Scharniers an der Gehäusebasis befestigt.

Die Figuren der Zeichnungen zeigen den erfindungsgemäßen Gegenstand stark schematisiert und sind nicht maßstäblich zu verstehen. Die einzelnen Bestandteile des erfindungsgemäßen Gegenstandes sind so dargestellt, dass ihr Aufbau gut gezeigt werden kann.The figures of the drawings show the subject matter of the invention in a highly schematic manner and are not to scale. The individual components of the article according to the invention are shown so that their structure can be well shown.

In Figur 1 ist ein erfindungsgemäßes Gehäuse 1, mit einer darin montierten Lufttexturierdüse 3, mit aufgeklapptem Gehäusedeckel 5 dargestellt. Weiter ist eine Benetzungseinrichtung 7 in dem Gehäuse 1 montiert. Mittels der Benetzungseinrichtung 7 kann der diese durchlaufende Faden z.B. befeuchtet werden, bevor der Faden die Lufttexturierdüse 3 durchläuft. Das Gehäuse 1 weist vier Fadendurchführungsöffnungen 10,11,12,13 auf. Der Gehäusedeckel 5 ist derart ausgeformt, dass er im zugeklappten Zustand die Gehäuseöffnung in einer Gehäusebasis 15 abdeckt. Zugeklappt schließt der Gehäusedeckel 5 mit Deckelkanten 17 an Gehäusebasiskanten 18 der Gehäusebasis 15 ab. Die Deckelkanten 17 sind dazu zu den Gehäusebasiskanten 18 komplementär ausgeformt. Zwischen den Deckelkanten 17 und den Gehäusebasiskanten 18 kann eine Dichtung vorgesehen sein. Die Fadendurchführungsöffnungen 10,11,12,13 sind an den Gehäusebasiskanten 18 angeordnet. Dadurch ist jeweils ein Teil des Umfangs der Fadendurchführungsöffnungen (Fadendurchführungsöffnungsumfang 20) von einer der Deckelkanten gebildet. Der jeweils andere Teil des Fadendurchführungsöffnungsumfangs 20 ist von einer im zugeklappten Zustand gegenüberliegenden Gehäusebasiskante gebildet. Die Fadendurchführungsöffnungen 10,11,12,13 sind derart relativ zu einer Montageposition 22 der Düse (Düsenmontageposition) in dem Gehäuse 1 angeordnet, dass die Fadendurchführungsöffnungen 10,11 in Fadeneinlaufrichtungen 24,25 der Düse liegen. Im dargestellten Fall der Lufttexturierdüse 3 bilden die Fadeneinlaufrichtungen 24,25 eines Kernfadens 27, die in der Zeichnung durch Pfeile an den entsprechenden Fäden markiert sind, und eines Hüllfadens 28. einen Rechten Winkel. Entsprechend ist eine Fadendurchführungsöffnung 10 mittig unter der Montageposition 22 der Lufttexturierdüse 3 und eine Fadendurchführungsöffnung 11 mittig an der Gehäusebasiskante einer rechten Seitenwand 30 des Gehäuses 1 positioniert. Eine weitere Fadendurchführungsöffnung 12 ist im unteren Bereich der Gehäusebasiskante der rechten Seitenwand 30 angeordnet. Diese Fadendurchführungsöffnung liegt in einer Fadeneinlaufrichtung der zu verarbeitenden Fäden beim Air-Covering. Das dargestellte Gehäuse 1 ist daher sowohl für Air-Covering Prozesse als auch für Lufttexturierprozesse einsetzbar. Durch die vierte Fadendurchführungsöffnung 13, die an der oberen Gehäusebasiskante über der Lufttexturierdüse 3 angeordnet wird, wird ein von der Lufttexturierdüse 3 bearbeitetes Garn 32 abgezogen, um nachfolgend z.B. auf eine Spule aufgespult zu werden. An den Fadendurchführungsöffnungen 10,11,12,13 ist ein Wolfszahn 35 innerhalb des Gehäuses 1 angeordnet. Weiter weisen die Gehäusebasis 15 und der Gehäusedeckel 5 im Bereich der Fadendurchführungsöffnungen 11,12 an der rechten Seitenwand 30 eine Verstärkung 37 auf. Der Gehäusedeckel 5 ist mittels eines Scharniers 40 an der Gehäusebasis 15 befestigt und weist ein Sichtfenster 41 auf.In FIG. 1 is a housing 1 according to the invention, with an air-texturing nozzle 3 mounted therein, with the housing cover 5 unfolded. Furthermore, a wetting device 7 is mounted in the housing 1. By means of the wetting device 7, the thread passing through these can be moistened, for example, before the thread passes through the air-texturing nozzle 3. The housing 1 has four Thread passage openings 10,11,12,13 on. The housing cover 5 is formed such that it covers the housing opening in a housing base 15 in the closed state. When closed, the housing cover 5 closes with cover edges 17 on housing base edges 18 of the housing base 15. The cover edges 17 are formed to complement the housing base edges 18 complementary. Between the lid edges 17 and the housing base edge 18 may be provided a seal. The thread passage openings 10, 11, 12, 13 are arranged on the housing base edges 18. Thereby, a part of the circumference of the thread passage openings (thread passage opening perimeter 20) is formed by one of the lid edges. The other part of the yarn feedthrough opening perimeter 20 is formed by a housing base edge opposite in the folded state. The thread passage openings 10,11,12,13 are arranged relative to a mounting position 22 of the nozzle (nozzle mounting position) in the housing 1, that the thread passage openings 10,11 are in thread inlet directions 24,25 of the nozzle. In the illustrated case of the air-texturing nozzle 3, the thread inlet directions 24, 25 of a core thread 27, which are marked by arrows on the corresponding threads in the drawing, and a wrapping thread 28, form a right angle. Accordingly, a yarn feedthrough opening 10 is positioned centrally below the mounting position 22 of the air texturing nozzle 3 and a yarn feedthrough opening 11 centrally on the housing base edge of a right side wall 30 of the housing 1. A further thread passage opening 12 is arranged in the lower region of the housing base edge of the right side wall 30. This thread passage opening is located in a thread inlet direction of threads to be processed in air-covering. The illustrated housing 1 can therefore be used both for air-covering processes and for air-texturing processes. Through the fourth yarn feedthrough opening 13, which is arranged on the upper housing base edge above the air-texturing nozzle 3, a yarn 32 processed by the air-texturing nozzle 3 is drawn off, in order subsequently to be wound on a reel, for example. At the thread passage openings 10,11,12,13 a wolf tooth 35 is disposed within the housing 1. Next, the housing base 15 and the housing cover 5 in the region of the thread passage openings 11,12 on the right side wall 30, a reinforcement 37. The housing cover 5 is fastened by means of a hinge 40 to the housing base 15 and has a viewing window 41.

In Figur 2 ist das erfindungsgemäße Gehäuse 1 mit zugeklapptem Gehäusedeckel 5 dargestellt. Der Gehäusedeckel 5 deckt eine Gehäuseöffnung in der Gehäusebasis 15 ab. Der Gehäusedeckel 5 schließt dazu mit Deckelkanten 17 an Gehäusebasiskanten 18 der Gehäusebasis 15 dicht ab. Lediglich an den Fadendurchführungsöffnungen 10,11,12,13 verbleiben im zugeklappten Zustand des Gehäuses 1 Öffnungen. Ein Schallaustritt durch diese Öffnungen wird dadurch vermindert, dass die Gehäusebasis 15 und der Gehäusedeckel 5 im Bereich der Fadendurchführungsöffnungen 11,12 an der rechten Seitenwand 30 eine Verstärkung 37 aufweisen, wodurch die Fadendurchführungsöffnungen 11,12 einen langgestreckten Kanal bilden. Durch das Sichtfenster 41 im Gehäusedeckel 5 ist die Montageposition 22 der Düse zu erkennen.In FIG. 2 the housing 1 according to the invention is shown with closed housing cover 5. The housing cover 5 covers a housing opening in the housing base 15. The housing cover 5 closes tightly with cover edges 17 on housing base edges 18 of the housing base 15. Only at the thread passage openings 10,11,12,13 remain in the closed state of the housing 1 openings. A sound leakage through these openings is reduced by the fact that the housing base 15 and the housing cover 5 in the region of the thread passage openings 11,12 on the right side wall 30 have a reinforcement 37, whereby the thread passage openings 11,12 form an elongated channel. Through the viewing window 41 in the housing cover 5, the mounting position 22 of the nozzle can be seen.
