Description
Die Erfindung bezieht sich auf eine Druckregelanordnung mit
den Merkmalen des Oberbegriffs des Patentanspruchs 1.The invention relates to a pressure control arrangement
the features of the preamble of
Die FR-A-2 580 190 zeigt eine Druckregelanordnung zwischen einer Kraftstoffpumpe und einem Verbrennungsmotor, bei der ein Druckregler und ein Filtereinsatz in einem gemeinsamen Gehäuse angeordnet sind. Ein Zulaufanschluss, ein Vorlaufanschluss und eine Abregelleitung sind zusammen mit dem Druckregler auf einer Seite des Gehäuses angeordnet. Vorteilhaft ist bei dieser Anordnung, dass die Bauteile der Druckregleranordnung herstellerseitig zu einer Einheit vormontiert werden können. Diese kann bei der Endmontage am Band mit wenigen Handgriffen in das Kraftstoffversorgungssystem des jeweiligen Fahrzeugs eingebaut werden. Zusätzliche Leitungsverbindungen zwischen dem Druckregler und dem Filter entfallen, so dass nicht nur die Teileanzahl, sondern auch der Arbeitsaufwand beträchtlich reduziert werden, weil der Druckregler mit dem Filter in einem gemeinsamen Gehäuse angeordnet ist, das einen Zulaufanschluss, einen Ablaufanschluss und einen Abregelanschluss aufweist. Dadurch wird die Filterpatrone bzw. das Filtergehäuse einfach stromab der Pumpe angeschlossen und leistet in Doppelfunktion die Druckbegrenzung und die Feinfilterung des Kraftstoffstroms. Eine besonders einfache und schnelle Montage wird bei der bekannten Druckregelanordnung erreicht, weil alle drei Anschlüsse auf derselben Seite des Filtergehäuses angeordnet sind und man dann z. B. zunächst das Filtergehäuse befestigen und danach an einer festen Basis die Leitungsanschlüsse herstellen kann.FR-A-2 580 190 shows a pressure control arrangement between a fuel pump and an internal combustion engine in which a pressure regulator and a filter insert in one Housing are arranged. One inlet connection, one Flow connection and a shutdown line are together with the pressure regulator arranged on one side of the housing. It is advantageous with this arrangement that the components of the Manufacturer's pressure regulator arrangement into one unit can be pre-assembled. This can be done during final assembly on Band in a few easy steps Fuel supply system of the respective vehicle to be built in. Additional line connections between the pressure regulator and the filter are eliminated, so that not only the number of parts, but also the amount of work considerably be reduced because the pressure regulator with the filter in a common housing is arranged, the one Inlet connection, one outlet connection and one Control port has. This will make the filter cartridge or the filter housing simply downstream of the pump connected and performs the double function Pressure limitation and fine filtering of the fuel flow. A particularly simple and quick installation is the known pressure control arrangement achieved because all three Connections arranged on the same side of the filter housing are and then z. B. first attach the filter housing and then the line connections on a fixed basis can manufacture.
Nachteilig bei der bekannten Druckregelanordnung ist, dass der Druckregler unmittelbar in dem Abregelanschluss montiert ist. Da bekannte Druckregler häufig eine Vielzahl von Bauteilen, wie beispielsweise eine Druckfeder und Einstellmittel zur Einstellung einer Schaltschwelle aufweisen, steht der Abregelanschluss weit von dem gemeinsamen Gehäuse ab. Weiterhin behindern an den Anschlüssen befestigte Leitungen die Zugänglichkeit des Druckreglers. Durch die abstehende Gestaltung des Abregelanschlusses sind die Anschlüsse nicht in einer Ebene angeordnet, was die Montage der Druckregelanordnung erschwert.A disadvantage of the known pressure control arrangement is that the pressure regulator is mounted directly in the regulating connection is. Since known pressure regulators often have a variety of Components such as a compression spring and Setting means for setting a switching threshold the cutoff connection is far from that common housing. Continue to hinder the Connections attached lines the accessibility of the Pressure regulator. Due to the protruding design of the regulating connection the connections are not on one level arranged what the assembly of the pressure control assembly difficult.
Die DE 94 14 297 U1 zeigt eine Druckregelanordnung mit einem Filter, bei dem ein Anschluss für einen Rücklauf unmittelbar an dem Druckregler angeschlossen ist. Ein Anschluss für eine Vorlaufleitung ist auf der gegenüberliegenden Seite des Gehäuses angeordnet. Durch die Anordnung der Anschlüsse auf unterschiedlichen Seiten des Gehäuses und des Druckreglers unter dem Abregelanschluss gestaltet sich die Montage der Druckregelanordnung und die Einstellung des Druckreglers sehr schwierig.DE 94 14 297 U1 shows a pressure control arrangement with a Filter with a connection for a return immediately is connected to the pressure regulator. One connection for one Flow line is on the opposite side of the Housing arranged. By arranging the connections different sides of the housing and the pressure regulator the installation of the Pressure control arrangement and the setting of the pressure regulator very much difficult.
Aus der DE 195 36 084 A1 ist eine Druckregelanordnung bekannt geworden, bei der der Druckregler neben einem Anschluss für einen Vorlauf angeordnet ist. Dies führt zu einem hohen Montageaufwand der Druckregelanordnung an an den Anschlüssen zu befestigenden Leitungen.A pressure control arrangement is known from DE 195 36 084 A1 where the pressure regulator is next to a connection for a lead is arranged. This leads to a high one Assembly effort of the pressure control arrangement on the connections cables to be fastened.
Der Erfindung liegt das Problem zugrunde, genügend Einbauraum
für die Anschlüsse einerseits und die Bauteile des
Druckreglers andererseits vorzusehen. Diese Aufgabe wird
erfindungsgemäß mit den kennzeichnenden Merkmalen des
Anspruchs 1 gelöst. Die Merkmale der Unteransprüche geben
vorteilhafte Weiterbildungen dieses Gegenstands an.The invention is based on the problem of sufficient installation space
for the connections on the one hand and the components of the
To provide pressure regulator on the other hand. This task will
according to the invention with the characteristic features of
Erfindungsgemäß ist der Druckregler an einer von den . Anschlüssen abgewandten Seite des Gehäuses angeordnet, so dass genügend Einbauraum für seine Bauteile einerseits und die Anschlüsse andererseits vorhanden ist. Daher können alle Anschlüsse in einer Ebene angeordnet sein, was die Montage erleichtert. Die meist sehr sperrigen Bauteile des Druckreglers stören den Anschluss der Leitungen nicht. Weiterhin lassen sich erfindungsgemäß die Einstellmittel des Druckreglers mit besonders geringem Aufwand an einer leicht zugänglichen Stelle der erfindungsgemäßen Druckregelanordnung vorsehen.According to the pressure regulator on one of the. Connections facing away from the housing, so that enough installation space for its components on the one hand and the connections on the other hand is present. So everyone can Connections can be arranged in one level, which is the assembly facilitated. The mostly very bulky components of the Pressure regulators do not interfere with the connection of the lines. Furthermore, the setting means of the Pressure regulator with particularly little effort on an easy accessible point of the pressure control arrangement according to the invention provide.
Ein vorteil ist es auch, wenn der Druckregler stromab des Filtereinsatzes angeordnet ist. Der langfristig steigende Drosselwiderstand des Filtereinsatzes hat so keinen Einfluss auf das Schaltverhalten des Druckreglers. Außerdem gelangt kein ungefilterter Kraftstoff in den Abregelkreislauf.It is also an advantage if the pressure regulator is downstream of the Filter insert is arranged. The long-term rising Throttle resistance of the filter insert has no influence on the switching behavior of the pressure regulator. Also got no unfiltered fuel in the regulating circuit.
Eine besonders kompakte Ausführung entsteht, wenn die Abregelleitung koaxial zu dem Filter angeordnet ist.A particularly compact design arises when the Discharge line is arranged coaxially to the filter.
Das gemeinsame Gehäuse wird vorzugsweise aus Blech bestehen und beidseits mit Deckeln dicht - z. B. durch Umbördeln - verschlossen werden. Zum mechanischen Festlegen der Einheit kann man in bekannter Weise eine Überwurfmutter oder dgl. vorsehen. Eine bedeutende Montagezeitersparnis wird erzielt, wenn alle drei Anschlüsse koaxial zueinander angeordnet sind und die Druckregelanordnung mit einem entsprechenden Anschlussstück mit drei entsprechenden, gegeneinander abdichtbaren Kanälen korrespondiert, mit dem sie durch Aufstecken oder Aufschrauben direkt verbunden werden kann.The common housing will preferably consist of sheet metal and sealed on both sides with lids - e.g. B. by flanging - be closed. For mechanical fixing of the unit can be a union nut or the like in a known manner. provide. A significant saving in assembly time is achieved if all three connections are arranged coaxially to each other and the pressure control arrangement with a corresponding one Connection piece with three corresponding, against each other sealable channels corresponds with which they pass through Plugging or screwing can be connected directly.
Weitere Einzelheiten und Vorteile des Gegenstands der Erfindung gehen aus der Zeichnung eines Ausführungsbeispiels und deren sich im folgenden anschließender eingehender Beschreibung hervor.Further details and advantages of the subject of Invention go from the drawing of an embodiment and which will be discussed in more detail below Description.
Die einzige Figur zeigt schematisch einen Querschnitt durch eine erfindungsgemäße Druckregelanordnung. The single figure shows schematically a cross section through a pressure control arrangement according to the invention.
In einem Gehäuse 1 (auch als Filterpatrone bezeichnet) ist in
an sich bekannter Weise
ein hohlzylindrischer Filtereinsatz 2 vorgesehen. Über einen Zulauf 3 mit einem Zulaufanschluß
4 wird von einer nicht gezeigten Pumpe Kraftstoff in das Gehäuse 1 gepumpt.
Dieser strömt von der äußeren Mantelfläche des Filtereinsatzes 2 in dessen Innenraum 5
über und wird dabei von Verunreinigungen mechanisch befreit. Vom Innenraum 5 des
Filtereinsatzes 2 strömt der Kraftstoff über einen Vorlauf 6 zum ebenfalls nicht dargestellten
Verbraucher. Er durchströmt dabei einen Vorlaufanschluß 7, an den eine nicht gezeigte
Vorlaufleitung anzuschließen ist. Mit dem Innenraum 5 kommuniziert nun auch ein Eingangsanschluß
8 (durchbrochene Gehäusewand) eines Druckreglers 9, dem somit ebenfalls
schon gefilterter Kraftstoff zugeführt wird. Am Druckreglereingang liegt somit der an
den Verbraucher weiterzuführende Vorlaufdruck an, der ca. 3.500 hPa (3,5 bar) beträgt.
Zum Druckregler 9 gehören ein Ventilkörper 10 und eine mit diesem fest verbundene
Membran 11. Letztere ist einerseits mit dem Vorlaufdruck flächig beaufschlagt, anderseitig
ist eine Druckfeder 12 angeordnet, die den Ventilkörper 10 gegen seinen Ventilsitz
13 vorspannt. Letzterer ist durch den Rand eines Einlaufs eines Abregelkanals 14
gebildet.
Die Vorspannung der Druckfeder 12 definiert zusammen mit der druckbeaufschlagten
Fläche der Membran 11 die Schaltschwelle des Druckreglers 9. Bevorzugt wird man
Mittel zum Einstellen der Vorspannung der Druckfeder vorsehen -z. B. eine Einstellschraube-,
um besagte Schaltschwelle nach Bedarf individuell anpassen und abstimmen
zu können.
Ersichtlich erstreckt sich der Abregelkanal 14 zentrisch koaxial durch den Innenraum 5
des Filtereinsatzes 3. Er mündet in einem Abregelanschluß 15, der an derselben Gehäuseseite
angeordnet ist wie die beiden anderen Anschlüsse 4 und 7.
Das Gehäuse ist vorzugsweise aus Blech gefertigt und wird an beiden Enden mit Deckeln
16, 17 dicht verschlossen. Der (linke) Deckel 16 umfaßt die drei Anschlüsse der Druckregelanordnung,
während der (rechte) Deckel 17 den Druckregler 9 nebst der Feder 12
abdeckt.
Abweichend von der bildlichen Darstellung kann man alle drei Anschlüsse des gemeinsamen
Gehäuses koaxial zueinander vorzugsweise zentrisch anordnen, wie es bisher bei
normalen Kraftstofffiltern mit nur zwei Anschlüssen schon bekannt ist. Zur weiteren Verteilung
der unterschiedlichen Ströme ist dann ein entsprechendes Anschlußstück mit drei
entsprechend koaxial mündenden, gegeneinander vollständig abdichtbaren und jenseits
des Anschlußstücks separat anschließbaren Kanälen vorzusehen.
An der Außenwand des äußeren Kanals des gemeinsamen Gehäuses ist dann z. B. ein
Gewinde vorzusehen, das in ein entsprechendes Gegenstück an dem besagten Anschlußstück
einschraubbar ist. Damit könnte eine solche Druckregelanordnung auch sehr
schnell und mit geringster Fehlerwahrscheinlichkeit angeschlossen bzw. ausgetauscht
werden.
Es kann z. B. -ohne Abwandlungen auszuschließen- zweckmäßig sein, die Abregelströmung,
wie in der Figur gezeigt, durch einen zentrisch innenliegenden Kanal 14 zu führen.
Im Mündungsbereich umgibt der Vorlauf 6 dieses als Ringkanal und ist seinerseits von
einem weiteren Ringkanal für den Zulauf 3 zum Filter umgeben. Selbstverständlich sind
alle drei Kanäle sorgfältig gegeneinander und nach außen hin abzudichten.A hollow
The pretension of the

The housing is preferably made of sheet metal and is sealed at both ends with
Deviating from the pictorial representation, all three connections of the common housing can be arranged coaxially with respect to one another, preferably centrally, as is already known with normal fuel filters with only two connections. To further distribute the different currents, a corresponding connection piece with three corresponding coaxial openings, which can be completely sealed off from one another and can be connected separately beyond the connection piece, must then be provided.
On the outer wall of the outer channel of the common housing z. B. provide a thread that can be screwed into a corresponding counterpart on said connector. Such a pressure control arrangement could also be connected or exchanged very quickly and with the lowest probability of error.
It can e.g. B.-without excluding modifications-be expedient to guide the regulating flow, as shown in the figure, through a centrally located
