Description

Die Erfindung betrifft ein mit einem Granulat-Strahlgerät kombiniertes Sauggerät mit einem Adapter, aufweisend ein Grundrohr wobei das Grundrohr

  • einen ersten Verbindungsabschnitt zum Anschluss an eine Absaugleitung des Sauggeräts und
  • einen zweiten Verbindungsabschnitt zum Anschluss an einen Arbeitsraum aufweist.
The invention relates to a suction device combined with a granular blasting device with an adapter, comprising a base tube, the base tube
  • a first connecting section for connection to a suction line of the suction device and
  • has a second connection section for connection to a work space.

Granulat-Strahlgeräte werden insbesondere dazu genutzt, um die Oberflächen von beliebigen Arbeitsräumen von Verunreinigungen zu befreien. Das als Granulat vorliegende Strahlmittel wird dabei unter Druck auf die zu reinigenden Oberflächen geleitet und entfernt dabei auch stärker anhaftende Verschmutzungen. Ein Einsatzbereich derartiger Strahlgeräte findet sich in Kraftfahrzeugwerkstätten, wo die Strahlgeräte dazu genutzt werden, um die Einlass- und Auslasskanäle von Zylinderköpfen von Kraftfahrzeugmotoren zu reinigen. Dabei entfernt das mit hohem Druck in die den Arbeitsraum bildende Einlasskanäle eingeführte Strahlmittel Verunreinigungen und Verkokungen von den Innenwänden der Einlasskanäle sowie auch von den Oberflächen der Einlassventile.Granular blasting devices are used in particular to free the surfaces of any work area from contamination. The abrasive, which is in the form of granules, is directed under pressure onto the surfaces to be cleaned and also removes heavily adhering dirt. One area of application of such blasting devices is found in motor vehicle workshops, where the blasting devices are used to clean the inlet and exhaust ports of cylinder heads of motor vehicle engines. The abrasive introduced at high pressure into the inlet ducts forming the working space removes impurities and coking from the inner walls of the inlet ducts and also from the surfaces of the inlet valves.

DE3314094 zeigt ein bekanntes Strahlgerät. DE3314094 shows a known blasting device.

Um eine ordnungsgemäße Reinigung zu gewährleisten, ist es erforderlich, sowohl das in die bspw. Einlasskanäle der Zylinderköpfe eingeblasene Strahlmittel wie auch die entfernten Verunreinigungen wieder aus dem Arbeitsraum zu entfernen. Im Falle der Verwendung der Strahlgeräte zur Reinigung der Einlasskanäle von Zylinderköpfen ist es bekannt, in die entsprechenden Öffnungen des Zylinderkopfs sogenannte Absaugadapter einzusetzen, welche mit Sauggeräten verbunden werden, die mit dem Granulat-Strahlgerät kombiniert sind. Neben einem strahlmitteldichten Anschluss an eine Absaugleitung des Sauggeräts ist insbesondere eine strahlmitteldichte Anordnung des Absaugadapters in der Öffnung des Arbeitsraums, bspw. der Zylinderkopföffnung von wesentlicher Bedeutung, um einen Austritt des Strahlmittels zu verhindern, was im Betrieb zu Verletzungen des Nutzers führen kann und auch das Reinigungsergebnis negativ beeinflusst.In order to ensure proper cleaning, it is necessary to remove both the abrasive blown into the intake ports of the cylinder heads and the contaminants removed from the work area. In the case of using the blasting devices for cleaning the inlet ducts of cylinder heads, it is known to use so-called suction adapters in the corresponding openings of the cylinder head, which are connected to suction devices that are combined with the granular blasting device. In addition to a blasting medium-tight connection to a suction line of the suction device, a blasting medium-tight arrangement of the suction adapter in the opening of the working space, for example the cylinder head opening, is particularly important in order to prevent the blasting medium from escaping, which can lead to injuries to the user during operation and also that Cleaning result negatively affected.

Die unterschiedliche Ausgestaltung der Zylinderköpfe und deren Öffnungen macht es daher erforderlich, in der Werkstatt für jeden Zylinderkopf einen entsprechend angepassten Saugadapter vorzuhalten, welcher einen strahlmitteldichten Anschluss des Saugadapters an dem Zylinderkopf und damit ein betriebssicheres Arbeiten ermöglicht.The different design of the cylinder heads and their openings therefore make it necessary to have a correspondingly adapted suction adapter in the workshop for each cylinder head, which enables a radiopaque connection of the suction adapter to the cylinder head and thus reliable operation.

Hiervon ausgehend liegt der Erfindung die Aufgabe zugrunde, die Anzahl der zum Anschluss an unterschiedliche Öffnungen von Arbeitsräumen notwendigen Saugadapter zu verringern.Proceeding from this, the object of the invention is to reduce the number of suction adapters required for connection to different openings in workrooms.

Die Erfindung löst die Aufgabe durch ein Sauggerät mit den Merkmalen des Anspruchs 1. Vorteilhafte Weiterbildungen der Erfindung sind in den abhängigen Ansprüchen angegeben.The invention solves the problem by a suction device with the features of claim 1. Advantageous further developments of the invention are specified in the dependent claims.

Kennzeichnend für den erfindungsgemäßen Adapter welcher einen ersten Verbindungsabschnitt zum Anschluss an eine Absaugleitung des Sauggeräts und einen zweiten Verbindungsabschnitt zum Anschluss an den Arbeitsraum aufweist ist, dass der zweite Verbindungsabschnitt aus einem flexiblen Material gebildet ist und an seinem Umfang eine sich ausgehend von einem freien Ende des zweiten Verbindungsabschnitts in Längsachsenrichtung des Grundrohres erstreckende Aussparung aufweist.It is characteristic of the adapter according to the invention, which has a first connection section for connection to a suction line of the suction device and a second connection section for connection to the work space, that the second connection section is formed from a flexible material and on its circumference a starting from a free end of the second connecting portion in the longitudinal axis direction of the base tube extending recess.

Gemäß der Erfindung ist somit vorgesehen, dass der zweite Verbindungsabschnitt, bei dem es sich um den Bereich des Grundrohres handelt, mit welchem der Adapter in einen Zylinderkopf bspw. eine Öffnung des Zylinderkopfes eingesetzt wird, aus einem flexiblen Material gebildet ist und darüber hinaus eine sich im Bereich des zweiten Verbindungsabschnitts von seinem freien Ende aus in Längsachsenrichtung des Grundrohres erstreckende Aussparung aufweist.According to the invention, it is therefore provided that the second connecting section, which is the region of the base pipe with which the adapter is inserted into a cylinder head, for example an opening of the cylinder head, is formed from a flexible material and, moreover, one has in the region of the second connecting portion from its free end extending in the longitudinal axis direction of the base tube recess.

Die den Rohrmantel durchdringende Aussparung sowie die Ausgestaltung des zweiten Verbindungsabschnitts aus einem flexiblen Material ermöglicht es, den Durchmesser des zweiten Verbindungsabschnitts durch Stauchen zu verringern, wobei die einander gegenüberliegenden Flächen der Aussparung aufeinander zubewegt werden, bis diese aneinander anliegen. Die Möglichkeit der Durchmesserveränderung erlaubt es, den Universaladapter auch in solchen Öffnungen des Arbeitsraums, insbesondere der Einlasskanäle des Zylinderkopfs anzuordnen, deren Öffnungsweite geringer ist als der Durchmesser des zweiten Verbindungsabschnitts in der Position, in der dieser nicht durch Stauchen der Aussparung verringert ist. Darüber hinaus erlaubt die flexible, üblicherweise elastische Verformung des Verbindungsabschnitts durch die Aussparung eine ortssichere Anordnung des zweiten Verbindungsabschnitts in der Öffnung, nachdem durch die elastische Rückverformung der zweite Verbindungsabschnitt mit seinem Umfang an die Innenseite der Öffnung angedrückt wird.The recess penetrating the tubular jacket and the configuration of the second connecting section made of a flexible material make it possible to reduce the diameter of the second connecting section by upsetting, the opposite surfaces of the recess being moved towards one another until they abut one another. The possibility of changing the diameter allows the universal adapter also to be arranged in openings of the working space, in particular of the intake ports of the cylinder head, the opening width of which is smaller than the diameter of the second connecting section in the position in which it is not reduced by upsetting the recess. In addition, the flexible, usually elastic deformation of the connecting section through the cutout allows the second connecting section to be arranged in a positionally secure manner in the opening, after the elastic reshaping presses the circumference of the second connecting section against the inside of the opening.

Die erfindungsgemäße Ausgestaltung des Adapters erlaubt es somit, diesen zum strahlmitteldichten Anschluss an eine Vielzahl von Zylinderköpfen zu verwenden, welche unterschiedliche Formen und Geometrien von Einlassöffnungen aufweisen. Im Betrieb einer Kraftfahrzeugwerkstatt erübrigt sich somit eine kostenintensive Anschaffung unterschiedlicher Saugadapter, welche jeweils nur zum Anschluss an einen spezifischen Zylinderkopf vorgesehen sind.The configuration of the adapter according to the invention thus allows it to be used for the blasting medium-tight connection to a multiplicity of cylinder heads which have different shapes and geometries of inlet openings. In the operation of a motor vehicle workshop, there is therefore no need for cost-intensive procurement of different suction adapters, which are only provided for connection to a specific cylinder head.

Grundsätzlich ist die Ausgestaltung der Aussparung frei wählbar. Auch besteht die Möglichkeit, mehrere Aussparungen, verteilt am Umfang im Bereich des zweiten Verbindungsabschnitts anzuordnen, um den Einsatzbereich des Universaladapters weiter zu erhöhen. Nach einer besonders vorteilhaften Ausgestaltung der Erfindung ist jedoch vorgesehen, dass die Aussparung V-förmig ausgebildet ist. Die V-förmige Ausgestaltung der Aussparung ermöglicht es, den zweiten Verbindungsabschnitt bereits bei der Verwendung einer einzigen Aussparung besonders variabel auszugestalten, sodass sich ein breiter Einsatzbereich des Universaladapters zum Anschluss an eine Vielzahl von Öffnungen von verschiedenen Arbeitsräumen ergibt. Darüber hinaus lässt sich eine V-förmige Aussparung besonders einfach und kostengünstig, bspw. durch Ausstanzen herstellen.Basically, the design of the recess is freely selectable. There is also the possibility of arranging several cutouts distributed around the circumference in the area of the second connecting section in order to further increase the area of use of the universal adapter. According to a particularly advantageous embodiment of the invention, however, it is provided that the recess is V-shaped. The V-shaped configuration of the cutout makes it possible to design the second connecting section to be particularly variable even when using a single cutout, so that there is a wide range of uses for the universal adapter for connection to a large number of openings in different work spaces. In addition, a V-shaped recess can be produced particularly simply and inexpensively, for example by punching out.

Die übrige Ausgestaltung des Adapters ist ebenfalls grundsätzlich frei wählbar. Nach einer besonders vorteilhaften Ausgestaltung der Erfindung ist jedoch vorgesehen, dass auch der erste Verbindungsabschnitt aus einem flexiblen Material gebildet ist, besonders bevorzugt an seinem freien Ende konisch aufgeweitet ist.The rest of the design of the adapter is also basically freely selectable. According to a particularly advantageous embodiment of the invention, however, it is provided that the first connecting section is also formed from a flexible material, particularly preferably widened conically at its free end.

Der erste Verbindungsabschnitt dient dazu, den Adapter mit einer Absaugleitung eines Sauggeräts zu verbinden. Hierzu ist es erforderlich, den ersten Verbindungsabschnitt bspw. auf einem Ansaugstutzen einer Saugleitung anzuordnen. Die Verwendung eines flexiblen Materials zur Ausgestaltung des ersten Verbindungsabschnitts erleichtert dabei die Anordnung des Universaladapters an einen solchen Ansaugstutzen. Darüber hinaus gewährleistet das flexible Material aufgrund seiner elastischen Eigenschaften einen sicheren Anschluss des Adapters an dem Ansaugstutzen. Eine konische Ausgestaltung des ersten Verbindungsabschnitts, wobei hierunter eine Ausgestaltung verstanden wird, bei der sich der erste Verbindungsabschnitt zu seinem freien Ende trichterförmig erweitert, erleichtert die Anordnung an einem Ansaugstutzten einer Absaugleitung in ergänzender Weise und ermöglicht somit eine komfortable Montage des AdaptersThe first connection section serves the adapter with a suction line to connect a suction device. For this purpose, it is necessary to arrange the first connecting section, for example, on an intake port of a suction line. The use of a flexible material for designing the first connecting section facilitates the arrangement of the universal adapter on such an intake port. In addition, the flexible material ensures a secure connection of the adapter to the intake manifold due to its elastic properties. A conical configuration of the first connection section, whereby this is understood to mean a configuration in which the first connection section widens in a funnel shape towards its free end, additionally facilitates the arrangement on an intake manifold of a suction line and thus enables the adapter to be mounted comfortably

Der gesamte Adapter, wie auch das Grundrohr, können aus einem beliebigen Material gebildet sein, sofern zumindest der zweite Verbindungsabschnitt in erfindungsgemäßer Weise aus einem flexiblen Material gebildet ist. Somit besteht grundsätzlich die Möglichkeit, das Grundrohr mehrteilig auszugestalten und die einzelnen Abschnitte dann miteinander zu verbinden. Nach einer besonders vorteilhaften Ausgestaltung der Erfindung ist jedoch vorgesehen, dass das Grundrohr einstückig mit den Verbindungsabschnitten aus einem flexiblen Material gebildet ist. Eine entsprechende Ausgestaltung der Erfindung zeichnet sich dabei dadurch aus, dass diese besonders einfach und kostengünstig herstellbar ist. Zudem bietet die durchgängige Verwendung eines flexiblen Materials die Möglichkeit, den Universaladapter durch elastisches Verbiegen in einfacher Weise zum Anschluss an die Absaugleitung auszurichten, nachdem die Flexibilität des Materials hierzu einen ausreichenden Handlungsspielraum bietet.The entire adapter, as well as the base tube, can be formed from any material, provided that at least the second connecting section is formed from a flexible material in the manner according to the invention. Thus, there is basically the possibility of designing the base pipe in several parts and then connecting the individual sections to one another. According to a particularly advantageous embodiment of the invention, however, it is provided that the base tube is formed in one piece with the connecting sections from a flexible material. A corresponding embodiment of the invention is characterized in that it is particularly simple and inexpensive to manufacture. In addition, the consistent use of a flexible material offers the possibility of simply aligning the universal adapter for connection to the suction line by elastic bending, after the flexibility of the material offers sufficient room for maneuver.

Weiter ist erfindungsgemäß vorgesehen, dass an dem Grundrohr eine Dichtmanschette angeordnet ist, die zwischen einer über das freie Ende des zweiten Verbindungsabschnitts vorstehenden Dichtposition und einer mindestens die Aussparung freigebenden Montageposition verstellbar ist. Gemäß dieser Weiterbildung der Erfindung ist an dem Grundrohr des Adapters eine Dichtmanschette verstellbar angeordnet, wobei die Dichtmanschette in der Dichtposition über das freie Ende des zweiten Verbindungsabschnitts vorsteht und so in der montierten Position des Adapters in der der zweite Verbindungsabschnitt in einer Öffnung des Arbeitsraums, bspw. des Zylinderkopfs angeordnet ist, auf einer die Öffnung umgebenden Fläche aufliegt und damit in ergänzender Weise die Öffnung abdichtet und den Austritt des Strahlmittels verhindert, sodass Schädigungen des Bedienpersonals durch austretendes Strahlmittel besonders zuverlässig verhindert werden können.It is further provided according to the invention that a sealing collar is arranged on the base tube, which can be adjusted between a sealing position projecting beyond the free end of the second connecting section and an assembly position which at least clears the recess. According to this development of the invention, a sealing sleeve is adjustably arranged on the base tube of the adapter, the sealing sleeve protruding over the free end of the second connecting section in the sealing position and thus in the assembled position of the adapter in which the second connecting section is in an opening in the working space, for example the cylinder head is arranged, rests on a surface surrounding the opening and thus in additionally seals the opening and prevents the blasting agent from escaping, so that damage to the operating personnel from the blasting agent escaping can be prevented particularly reliably.

Die Dichtmanschette kann dabei aus einem beliebigen Material gebildet sein, ist jedoch vorzugsweise aus einem flexiblen Kunststoff gebildet, der eine gute Abdichtung und Anpassung an die Oberfläche bietet an der die Dichtungsmanschette im Bereich der Öffnung anliegt. Die Verstellbarkeit der Dichtmanschette erlaubt es dabei, das Grundrohr in der Montageposition der Dichtmanschette komfortabel mit dem zweiten Verbindungsabschnitt in der Öffnung des Arbeitsraums anzuordnen. Anschließend kann dann die Dichtmanschette in die Dichtposition überführt werden, in der die Öffnung zuverlässig abgedichtet ist und der Strahlprozess begonnen werden kann.The sealing sleeve can be made of any material, but is preferably made of a flexible plastic that offers a good seal and adaptation to the surface on which the sealing sleeve rests in the area of the opening. The adjustability of the sealing sleeve allows the base tube to be comfortably arranged in the mounting position of the sealing sleeve with the second connecting section in the opening of the work space. The sealing collar can then be transferred to the sealing position in which the opening is reliably sealed and the blasting process can be started.

Das Strahlmittel kann grundsätzlich an beliebiger Stelle in den Arbeitsraum, bspw. die Einlasskanäle eines Zylinderkopfs eingebracht werden. Nach einer besonders vorteilhaften Ausgestaltung der Erfindung ist jedoch vorgesehen, dass das Grundrohr an seinem Umfang eine den Rohrmalte durchdingende Sondenbohrung aufweist, die in Richtung auf den zweiten Verbindungsabschnitt ausgerichtet ist. Gemäß dieser Ausgestaltung der Erfindung stellt die Sondenbohrung eine Öffnung an dem Grundrohr dar, durch die die Strahlsonde, mittels der das Strahlmittel in den Arbeitsraum eingebracht wird, über das Grundrohr in den Arbeitsraum geführt werden kann. Die Ausrichtung der Sondenbohrung in Richtung auf den zweiten Verbindungsabschnitt gewährleistet dabei eine gute Führung der Sonde beim Einführen in das Grundrohr und gewährleistet, dass die Sonde in den Arbeitsraum gelangt.The blasting agent can in principle be introduced into the work area at any point, for example the inlet ducts of a cylinder head. According to a particularly advantageous embodiment of the invention, however, it is provided that the base pipe has on its circumference a probe bore penetrating the pipe painting, which is aligned in the direction of the second connecting section. According to this embodiment of the invention, the probe bore represents an opening on the base tube through which the blasting probe, by means of which the blasting agent is introduced into the work space, can be guided into the work space via the base tube. The alignment of the probe bore in the direction of the second connecting section ensures good guidance of the probe when it is inserted into the base pipe and ensures that the probe gets into the working space.

Durch diese Ausgestaltung der Erfindung kann auf weitere Zugangsöffnungen, welche ggf. abgedichtet werden müssen, verzichtet werden. Dabei ist die nach einer bevorzugten Weiterbildung vorgesehene flexible Ausgestaltung des Grundrohres von besonderem Vorteil, da sie, bei einer entsprechenden Anpassung des Durchmessers der Sondenbohrung an die einzuführende Sonde, eine automatische Abdichtung der Sonde gegenüber dem Grundrohr bietet. Als flexible Materialien eignen sich dabei bspw. verschiedene Arten von Kunststoffen, wobei besonders bevorzugt das Grundrohr bspw. aus einem textilverstärkten Kunststoffschlauch gebildet ist.This embodiment of the invention makes it possible to dispense with further access openings, which may have to be sealed off. The flexible configuration of the base pipe, which is provided according to a preferred development, is particularly advantageous since, with a corresponding adaptation of the diameter of the probe bore to the probe to be inserted, it provides an automatic seal of the probe with respect to the base pipe. Various types of plastics are suitable, for example, as flexible materials, the base tube being particularly preferably formed, for example, from a textile-reinforced plastic tube.

Der Verlauf der Sondenbohrung in Richtung auf den zweiten Verbindungsabschnitt kann dabei grundsätzlich in beliebiger Weise erfolgen. Nach einer besonders vorteilhaften Ausgestaltung der Erfindung ist jedoch vorgesehen, dass eine Längsachse der Sondenbohrung mit der Längsachse des Grundrohres einen Winkel von 10° bis 60°, bevorzugt 15° bis 40°, besonders bevorzugt 20° bis 30° einschließt.The course of the probe bore in the direction of the second connection section can in principle take place in any manner. According to a particularly advantageous embodiment of the invention, however, it is provided that a longitudinal axis of the probe bore forms an angle with the longitudinal axis of the base tube of 10 ° to 60 °, preferably 15 ° to 40 °, particularly preferably 20 ° to 30 °.

Die gemäß dieser Weiterbildung der Erfindung vorgesehenen Winkel der Sondenbohrung ermöglichen es, die Sondenbohrung in besonders komfortabler und einfacher Weise durch die Sondenbohrung in den Arbeitsraum einzuführen. Insbesondere ein Winkel der Sondenbohrung zur Längsachse von besonders bevorzugt 20° bis 30°, insbesondere 25° stellt dabei einen Winkel dar, der eine optimale Platzierung der Sondenbohrung innerhalb des Arbeitsraums ermöglicht.The angles of the probe bore provided according to this development of the invention make it possible to insert the probe bore through the probe bore into the working space in a particularly convenient and simple manner. In particular, an angle of the probe bore to the longitudinal axis of particularly preferably 20 ° to 30 °, in particular 25 °, represents an angle which enables the probe bore to be optimally placed within the working space.

Die Sondenbohrung kann dabei grundsätzlich an beliebiger Stelle an dem Grundrohr angeordnet sein. Nach einer besonders vorteilhaften Ausgestaltung der Erfindung ist jedoch vorgesehen, dass die Sondenbohrung im Bereich zwischen dem zweiten Verbindungsabschnitt und einem Mittelbereich des Grundrohres angeordnet ist. Eine entsprechende Anordnung der Sondenbohrung erlaubt es auch im montierten Zustand des Universaladapters die Sonde besonders einfach und komfortabel in das Grundrohr einzuführen und mit der Sondenöffnung im Arbeitsraum anzuordnen. Zudem kann die Sonde innerhalb der Sondenbohrung bewegt werden, wodurch der gesamte Arbeitsraum durch das eingebrachte Strahlmittel von Verunreinigungen gereinigt werden kann, welche ebenso wie das eingebrachte Strahlmittel über das Saugrohr abgeführt werden.The probe bore can in principle be arranged anywhere on the base tube. According to a particularly advantageous embodiment of the invention, however, it is provided that the probe bore is arranged in the region between the second connecting section and a central region of the base pipe. A corresponding arrangement of the probe hole allows the probe to be inserted particularly easily and comfortably into the base tube and to be arranged with the probe opening in the work space, even when the universal adapter is in the installed state. In addition, the probe can be moved within the probe bore, as a result of which the entire working area can be cleaned of impurities by the blasting agent introduced, which, like the blasting agent introduced, are removed via the suction pipe.

Nach einer weiteren Ausgestaltung der Erfindung ist ferner vorgesehen, dass die Sondenbohrung auf der der Aussparung gegenüberliegenden Seite des Grundrohres angeordnet ist. Gemäß dieser Ausgestaltung der Erfindung verläuft die Sondenbohrung diametral zur Aussparung an dem Grundrohr, wobei diese in Längsachsenrichtung in Richtung auf den ersten Verbindungsabschnitt verschoben ist. Eine entsprechende Anordnung der Sondenbohrung gegenüber der Aussparung gewährleistet eine besonders hohe Stabilität des Grundrohres.According to a further embodiment of the invention it is further provided that the probe bore is arranged on the side of the base tube opposite the recess. According to this embodiment of the invention, the probe bore runs diametrically to the recess on the base tube, which is displaced in the longitudinal axis direction in the direction of the first connecting section. A corresponding arrangement of the probe hole in relation to the recess ensures a particularly high stability of the base tube.

Ein Ausführungsbeispiel der Erfindung wird nachstehend mit Bezug auf die Zeichnungen erläutert. In den Zeichnungen zeigen:

eine Ansicht von unten auf den Adapter von Fig. 1.
An embodiment of the invention will be described below with reference to the drawings explained. The drawings show:
Fig. 1
a perspective view of an adapter
Fig. 2
a top view of the adapter from Fig. 1 and
Fig. 3
a bottom view of the adapter from Fig. 1 .

In den Figuren 1 bis 3 ist eine Ausführungsform eines Adapters 1 dargestellt.In the Figures 1 to 3 An embodiment of an adapter 1 is shown.

Dieser weist ein aus einem textilverstärkten Kunststoff hergestelltes Grundrohr 2 auf, welches an seinem zweiten Verbindungsabschnitt 4 zur Anordnung in verschiedenen Öffnungen hier nicht dargestellter Arbeitsräume bspw. verschiedener Zylinderköpfe eine V-förmige Aussparung 5 aufweist. Die den Rohrmantel durchdringende Aussparung 5 erstreckt sich dabei ausgehend von einer Stirnfläche 8 des zweiten Verbindungsabschnitts 4 in Längsachsenrichtung des Grundrohres 2 in Richtung auf einen ersten Verbindungsabschnitt 3 und ermöglicht es, den zweiten Verbindungsabschnitt 4 im Bereich der Aussparung 5 zu stauchen, sodass sich der Durchmesser durch eine Annäherung der einander gegenüberliegenden Stirnflächen der Aussparung 5 verändert. Der zweite Verbindungsabschnitt 4 kann dadurch in Öffnungen der Arbeitsräume mit unterschiedlichen Durchmessern angeordnet werden.This has a base pipe 2 made of a textile-reinforced plastic, which has a V-shaped recess 5 on its second connecting section 4 for arrangement in different openings, not shown here, for example, different cylinder heads. The recess 5 penetrating the tubular jacket extends from an end face 8 of the second connection section 4 in the longitudinal axis direction of the base pipe 2 in the direction of a first connection section 3 and enables the second connection section 4 to be compressed in the region of the recess 5, so that the diameter increases changed by an approach of the opposite end faces of the recess 5. The second connecting section 4 can thereby be arranged in openings in the working spaces with different diameters.

Koaxial zu dem Grundrohr 2 ist eine Dichtmanschette 6 angeordnet, welche in Figur 1 bis Figur 3 in ihrer Montageposition dargestellt ist. In der Montageposition erlaubt die Zugänglichkeit zum zweiten Verbindungsabschnitt 4 dessen einfache Anordnung in einer Öffnung des Arbeitsraums. Nach einer Anordnung des zweiten Verbindungsabschnitts 4 wird dann die Dichtmanschette 6 in Richtung auf das freie Ende des zweiten Verbindungsabschnitts 4 verschoben, bis diese mit ihrer parallel zur Stirnfläche 8 verlaufenden Dichtfläche im Bereich um die Öffnung, in der der zweite Verbindungsabschnitt 4 angeordnet ist, auf der Oberfläche aufliegt.A sealing sleeve 6 is arranged coaxially to the base pipe 2, which in Figure 1 to Figure 3 is shown in its mounting position. In the assembly position, the accessibility to the second connecting section 4 permits its simple arrangement in an opening in the work space. After arranging the second connecting section 4, the sealing sleeve 6 is then displaced in the direction of the free end of the second connecting section 4 until it has its sealing surface running parallel to the end face 8 in the area around the opening in which the second connecting section 4 is arranged rests on the surface.

Eine auf der der Aussparung 5 gegenüberliegenden Seite angeordnete, den Rohrmantel durchdringende Sondenbohrungen 7 verläuft in Richtung auf den zweiten Verbindungsabschnitt 4 in einem mittleren Bereich des Grundrohres 2. Die Sondenbohrung 7 erlaubt die Anordnung einer hier nicht dargestellten Strahlsonde, mittels der das Strahlmittel in den Arbeitsraum eingebracht wird.A probe holes 7 arranged on the side opposite the cutout 5 and penetrating the tube jacket runs in the direction of the second connecting section 4 in a central region of the base tube 2. The probe bore 7 allows the arrangement of a blasting probe, not shown here, by means of which the blasting agent into the working area is introduced.
