Abstract
Pumpengehäuse mit einem metallischen Gehäuseteil (1), an dem eine Heizeinrichtung (2) angeordnet ist und das eine Öffnung (4) für den Fluidzulauf oder -ablauf aufweist, wobei an der Öffnung (4) ein Anschlussstutzen (5) fluiddicht angebracht ist, dadurch gekennzeichnet, dass der Anschlussstutzen (5) umlaufend um die Öffnung (4) angespritzt ist, und zwischen dem Gehäuseteil (1) und dem Anschlussstutzen (5) eine Dichtung (6) angeordnet ist, wobei die Dichtung (6) vollständig umlaufend um die Öffnung im Pumpengehäuse (1) in den Zulaufstutzen (5) eingespritzt und beim Einspritzen die Dichtung (6) elastisch komprimiert ist.Pump housing with a metallic housing part (1) on which a heating device (2) is arranged and which has an opening (4) for the fluid inlet or outlet, a connecting piece (5) being attached to the opening (4) in a fluid-tight manner, characterized characterized in that the connecting piece (5) is molded all the way around the opening (4), and a seal (6) is arranged between the housing part (1) and the connecting piece (5), the seal (6) running all the way around the opening injected into the inlet connection (5) in the pump housing (1) and the seal (6) is elastically compressed during injection.
Description
Die Erfindung geht aus von einem beheizten Pumpengehäuse mit den im Oberbegriff des Anspruchs 1 angegebenen Merkmalen, wie sie beispielsweise aus
In
In der Mitte der Pumpenoberseite befindet sich der Zulauf in Form eines Zulaufstutzens für das Pumpenmedium. Wie man den Zeichnungen und der Beschreibung entnehmen kann, bedarf es zur Befestigung des Zulaufstutzens weiterer Bauteile wie beispielsweise Manschette, Klemmring und Dichtung, um den Zulaufstutzen so dicht gegen die Pumpengehäuseoberseite abzudichten, dass auch bei Zufuhr des Pumpenmediums unter hohem Druck eine zuverlässige Abdichtung gegeben ist.The inlet is located in the middle of the top of the pump in the form of an inlet nozzle for the pump medium. As can be seen from the drawings and the description, additional components such as sleeves, clamping rings and seals are required to fasten the inlet connection in order to seal the inlet connection so tightly against the top of the pump housing that reliable sealing is also provided when the pump medium is supplied under high pressure .
Vor diesem Hintergrund besteht die Aufgabe der Erfindung deshalb darin, einen Anschlussstutzen zu schaffen, der eine sichere Verbindung zwischen einem Pumpengehäuseteil mit einem daran angeordnetem Heizelement und einem Anschlussstutzen für das Pumpenmedium gewährleistet.Against this background, the object of the invention is therefore to create a connection piece that ensures a secure connection between a pump housing part with a heating element arranged thereon and a connection piece for the pump medium.
Diese Aufgabe wird durch eine Heizeinrichtung mit den im Anspruch 1 angegebenen Merkmalen gelöst. Vorteilhafte Weiterbildungen der Erfindung sind Gegenstand von Unteransprüchen.This object is achieved by a heating device having the features specified in
Durch das Anspritzen eines Anschlussstutzens an eine Öffnung im mit einer Heizung versehenen Pumpengehäuseteil können vorteilhaft weitere separate Bauteile wie Dichtungen und/oder Klemmringe entfallen, was zu einer sehr viel kostengünstigeren Fertigung beiträgt. Weiterhin ist durch die stoffschlüssige Verbindung die Gefahr von Undichtigkeiten zwischen den einzelnen Bauteilen nicht mehr gegeben.By molding a connecting piece onto an opening in the pump housing part provided with a heater, further separate components such as seals and/or clamping rings can advantageously be omitted, which contributes to a much more cost-effective production. Furthermore, the risk of leaks between the individual components is no longer given by the material connection.
Vorteilhaft weist die Umspritzung einen Formschluss mit dem Gehäuseteil auf, was zur Stabilität der Verbindung wesentlich beiträgt. Insbesondere ist der Formschluss im Verbindungsbereich als Hinterschneidung entlang des Gehäuserandes um die Öffnung ausgeführt.The encapsulation advantageously has a positive fit with the housing part, which contributes significantly to the stability of the connection. In particular, the form fit in the connection area is designed as an undercut along the edge of the housing around the opening.
Erfindungsgemäß ist umlaufend zwischen dem Pumpengehäuse und dem Anschlussstutzen eine Dichtung mit eingespritzt.According to the invention, a seal is injected around the circumference between the pump housing and the connecting piece.
Alternativ ist, z.B. in einem zweistufigen Verfahren, zunächst ein elastisches Dichtmaterial an das Pumpengehäuse angespritzt und anschließend ist dann der Anschlussstutzen unter Kompression des Dichtmaterials an diese Verbindung angespritzt.Alternatively, e.g. in a two-stage process, an elastic sealing material is first injection-moulded onto the pump housing and then the connecting piece is then injection-moulded onto this connection while compressing the sealing material.
Bei dem Pumpengehäuseteil handelt es sich bevorzugt um einen Gehäuseboden oder -deckel, der eine zentrale Öffnung für den Zulaufanschluss des zu erwärmenden Fluids aufweist.The pump housing part is preferably a housing base or cover which has a central opening for the inlet connection of the fluid to be heated.
Weitere Einzelheiten und Vorteile der Erfindung werden an Ausführungsbeispielen unter Bezugnahme auf die beigefügten Zeichnungen erläutert. Gleiche und einander entsprechende Komponenten sind darin mit übereinstimmenden Bezugszeichen bezeichnet. Es zeigen:
-
1 Pumpendeckel mit Heizelement und angespritztem Zulaufstutzen -
2 alternative Ausgestaltung zu1 mit eingespritztem Dichtelement -
3 alternative Ausgestaltung zu1 mit angespritztem Dichtelement vom Zulaufstutzen umspritzt.
-
1 Pump cover with heating element and molded inlet connection -
2 alternative design 1 with injected sealing element -
3 alternative design 1 overmoulded with a molded sealing element from the inlet connection.
