Das Befestigungsteil 6 hat eine etwa rechteckförmige Befestigungsfläche 7, an die sich in etwa senkrecht zur Befestigungsfläche 7 eine etwa rechteckförmige Zwischenfläche 8 anschließt. An die Zwischenfläche 8 schließt sich mit einem stumpfen Winkel das Anschlußteil 5 an. Das Anschlußteil 5 hat an seiner Stirnfläche 11 eineConnection part 5 and an angular fastening part 6, together. The fastening part 6 has an approximately Rectangular fastening surface 7, to which an approximately rectangular intermediate surface 8 connects approximately perpendicular to the fastening surface 7. The connecting part 5 adjoins the intermediate surface 8 at an obtuse angle. The connection part 5 has a on its end face 11
Ausnehmung 10, die der äußeren Form des Regenerierventils 3, beziehungsweise einer Querschnittsfläche des Regenerierventils 3, zumindest teilweise entspricht. Wie in der Figur 2, einer perspektivischen Darstellung des erfindungsgemäßen Haltebügels 1 mit befestigtem Regenerierventil 3, dargestellt ist, besitzt das Regenerierventil 3 beispielsweise eine abgestufte, zylindrische Außenfläche 12 und die Ausnehmung 10 zum Beispiel eine etwa halbkreisförmige oder U-förmige Form. Die Ausnehmung 10 wird von zwei in der Figur 1 links dargestellten Gabeln 15 teilweise begrenzt, die von einer schmalen Seitenfläche 14 des Anschlußteils 5 abstehen. Das Regenerierventil 3 hat am Umfang der Außenfläche 12 eine ausgenommene Ringnut 16, mit der das Regenerierventil 3 zwischen den Gabeln 15 in die Ausnehmung 10 seitlich amRecess 10, which at least partially corresponds to the outer shape of the regeneration valve 3, or a cross-sectional area of the regeneration valve 3. As shown in Figure 2, a perspective view of the bracket 1 according to the invention with attached regeneration valve 3, the regeneration valve 3 has, for example, a stepped, cylindrical outer surface 12 and the recess 10, for example, an approximately semicircular or U-shaped shape. The recess 10 is partially delimited by two forks 15 shown on the left in FIG. 1, which protrude from a narrow side surface 14 of the connecting part 5. The regeneration valve 3 has a recessed annular groove 16 on the circumference of the outer surface 12, with which the regeneration valve 3 between the forks 15 in the recess 10 on the side
Haltebügel 1 eingeführt wird, wonach die Ringnut 16 in der U-förmigen Ausnehmung 10 und teilweise an den Gabeln 15 anliegt. Die Erstreckung der Gabeln 15 ist derart gewählt, daß Gabelenden 17 der Gabeln 15 im eingeschobenen Zustand des Regenerierventils 3 von dessen Außenfläche 12 etwas abstehen. Nach dem Einschieben des Regenerierventils 3 in die Ausnehmung 10 kann das Regenerierventil 3 noch in der Ausnehmung 10 gedreht werden, um mit präziser Drehlage, beispielsweise durch Verstemmen der Gabeln 15, mit dem Regenerierventil 3 fest verbunden zu werden.Retaining bracket 1 is inserted, after which the annular groove 16 rests in the U-shaped recess 10 and partially on the forks 15. The extension of the forks 15 is selected such that fork ends 17 of the forks 15 protrude somewhat from the outer surface 12 of the regeneration valve 3 in the inserted state. After inserting the regeneration valve 3 into the recess 10, the regeneration valve 3 can still be rotated in the recess 10 in order to be firmly connected to the regeneration valve 3 with a precise rotational position, for example by caulking the forks 15.
ie in der Figur 3, einer teilweisen Schnittdarstellung des erfindungsgemäßen Haltebügels 1, dargestellt ist, ist die Ringnut 16 beispielsweise gegenüberliegend eines Steckanschlusses 18 in der Nähe eines Schlauchanschlusses 19 aus der Außenfläche 12 des Regenerierventils 3 ausgearbeitet. Der Steckanschluß 18 ist zur elektrischen Kontaktierung des Regenerierventils 3 vorgesehen, wozu beispielsweise ein elektrischer Stecker in den Steckanschluß 18 eingeführt wird. Der Schlauchanschluß 19 dient bekanntermaßen zur steckbaren Aufnahme einer nicht näher dargestellten Schlauchleitung, in welcher vom3, a partial sectional illustration of the retaining bracket 1 according to the invention, the annular groove 16 is, for example, opposite a plug connection 18 in the vicinity of a hose connection 19 from the outer surface 12 of the regeneration valve 3. The plug connector 18 is for electrical Contacting of the regeneration valve 3 is provided, for which purpose, for example, an electrical plug is inserted into the plug connection 18. The hose connector 19 is known to be used for pluggable reception of a hose line, not shown, in which from
Regenerierventil 3 in den Schlauchanschluß 19 abgegebener Brennstoff zum Ansaugrohr der Brennkraftmaschine strömt. Der mit dem Regenerierventil 3 verbundene Haltebügel 1 ist an einer in Figur 3 schraffiert dargestellten Gehäusewandung 22 befestigt, die beispielsweise Teil einerRegeneration valve 3 in the hose connection 19 discharged fuel flows to the intake pipe of the internal combustion engine. The holding bracket 1 connected to the regeneration valve 3 is fastened to a housing wall 22 shown hatched in FIG. 3, which is part of a housing wall 22, for example
Motorrauminnenwandung eines Motorinnenraums oder ein Teil der Brennkraftmaschine darstellt. Die Montage des Regenerierventils 3 erfolgt mit angebrachtem Haltebügel 1, wobei sich durch eine an die eingeschränkten Einbaumδglichkeiten im Motorinnenraum angepaßte Formgebung des Haltebügels 1 eine Vielzahl möglicher Einbauorte an der Gehäusewandung 22 ergeben. Dabei kann durch Änderung der Form des Haltebügels 1, beispielsweise durch Biegen, in einfacher Art und Weise ein Anpassung an verschiedene Einbauorte erfolgen, so daß die Halterung universell, insbesondere für verschiedene Motorausführungen, eingesetzt werden kann. Zur Befestigung des Haltebügels 1 ist beispielsweise eine Schraubverbindung vorgesehen, wozu aus dem Befestigungsteil 6 des Haltebügels 1 eine in den Figuren 1 und 2 sichtbare Öffnung 24 ausgenommen ist. Durch die Öffnung 24 des Haltebügels 1 wird eine Schraube 26 hindurchgeführt und beispielsweise mittels einer Kontermutter 27 verdrehsicher gehalten. Es ist auch möglich, in der Gehäusewandung 22 ein Innengewinde vorzusehen, um die Schraube 26 in das Innengewinde einzuschrauben.Engine compartment wall of an engine compartment or part of the internal combustion engine. The regeneration valve 3 is mounted with the retaining bracket 1 attached, and a plurality of possible installation locations on the housing wall 22 result from a shape of the retaining bracket 1 which is adapted to the restricted installation possibilities in the engine interior. By changing the shape of the bracket 1, for example by bending, it can be easily adapted to different installation locations, so that the holder can be used universally, in particular for different engine designs. A screw connection is provided, for example, for fastening the holding bracket 1, for which purpose an opening 24 visible in FIGS. 1 and 2 is excluded from the fastening part 6 of the holding bracket 1. A screw 26 is passed through the opening 24 of the holding bracket 1 and held in a rotationally secure manner, for example by means of a lock nut 27. It is also possible to provide an internal thread in the housing wall 22 in order to screw the screw 26 into the internal thread.
Wie in der Figur 2 dargestellt ist, sind aus dem Befestigungsteil 6 zwei Schlitze 29 ausgenommen, die beispielsweise beginnend von einer schmalen Seitenfläche 31 des Befestigungsteils 6 sich parallel in Richtung derAs shown in FIG. 2, two slots 29 are excluded from the fastening part 6, which, for example, starting in parallel from the narrow side face 31 of the fastening part 6, run in the direction of the
Öffnung 24 teilweise erstrecken, um zwischen den Schlitzen 29 einen Metallstreifen auszusparen, der im gebogenen Zustand ein Zentrierteil 28 bildet. Das Zentrierteil 28 steht beispielsweise senkrecht von der Befestigungsfläche 7 des Befestigungsteils 6 ab, um beim Anbringen des Haltebügels 1 in eine in der Gehäusewandung 22 korrespondierende Öffnung 32 einzugreifen, so daß beimPartially extend opening 24 to leave a metal strip between slots 29, which is in the bent State forms a centering part 28. The centering part 28 projects, for example, perpendicularly from the fastening surface 7 of the fastening part 6 in order to engage in an opening 32 corresponding in the housing wall 22 when the holding bracket 1 is attached, so that when the
Anschrauben eine präzise VorZentrierung des Haltebügels 1 erfolgt, beziehungsweise eine Verdrehung des Haltebügels 1 ausgeschlossen ist. Es ist auch möglich, andere Verbindungsmittel zur Anbringung des Haltebügels 1 an der Gehäusewandung 22 vorzusehen, beispielsweise kann dies auch mittels einer Klebverbindung oder mittels einer Schweißverbindung erfolgen.Screwing a precise pre-centering of the bracket 1 takes place, or a rotation of the bracket 1 is excluded. It is also possible to provide other connecting means for attaching the holding bracket 1 to the housing wall 22, for example this can also be done by means of an adhesive connection or by means of a welded connection.
Wie in den Figuren 1 und 3 dargestellt ist, bedeckt eine aus elastischem Material, beispielsweise aus Gummi hergestellte Zwischenschicht 35 die dem Schlauchanschluß 19 zugewandte Befestigungsfläche 7 des Befestigungsteils 6. Die Zwischenschicht 35 ist beispielsweise durch Kleben mit der Befestigungsfläche 7 verbunden. Die Zwischenschicht 35 ist gegebenenfalls erforderlich, um die beim Betrieb desAs shown in FIGS. 1 and 3, an intermediate layer 35 made of elastic material, for example rubber, covers the fastening surface 7 of the fastening part 6 facing the hose connection 19. The intermediate layer 35 is connected to the fastening surface 7 by gluing, for example. The intermediate layer 35 may be necessary in order to ensure that the operation of the
Regenerierventils 3 und der Brennkraftmaschine entstehenden Schwingungen abzudämpfen. Darüber hinaus vermeidet die Zwischenschicht 35, daß vom Regenerierventil 3 ausgehende Geräusche nicht über den Haltebügel 1 und über die Gehäusewandung 22 zum Fahrzeuginneren übertragen werden. Um die Schwingungsdämpfung weiter zu verbessern, kann die Zwischenschicht 35 noch Längsnuten 37 aufweisen, die aus einer der Gehäusewandung 22 zugewandten Oberfläche 36 der Zwischenschicht 35 ausgenommen sind, um beim Anschrauben des Haltebügels 1 eine elastische Verformung der Zwischenschicht 35 zu ermöglichen. To dampen regeneration valve 3 and the internal combustion engine vibrations. In addition, the intermediate layer 35 avoids that noises emanating from the regeneration valve 3 are not transmitted to the vehicle interior via the retaining bracket 1 and the housing wall 22. In order to further improve the vibration damping, the intermediate layer 35 can also have longitudinal grooves 37, which are recessed from a surface 36 of the intermediate layer 35 facing the housing wall 22, in order to enable the intermediate layer 35 to be elastically deformed when the retaining bracket 1 is screwed on.
