Abstract

The unit incorporates a suction line with at least two suction line openings (5,6), of which one (6) leads to the IC engine via a line of constant cross-section. The other opening (5) connects to the engine via a rotary slide valve. The valve consists of a tubular section with a central wall on a dia. along its length. The valve is symmetrical about its rotation axis. The rotary valve is mounted in a flange on the suction module in such a way that it can float to centralise itself in the valve opening.

Description

Die Erfindung betrifft ein Saugmodul, insbesondere für Brennkraftmaschinen mit wenigstens einem Ansaugtrakt. Derartige Saugmodule sind bekannt, z. B. aus der deutschen Patentanmeldung DE 40 32 250.The invention relates to a suction module, in particular for internal combustion engines with at least one intake tract. Such suction modules are known, for. B. from German patent application DE 40 32 250.

Will man derartige Saugmodule in z. B. PKWs verwenden, so ist daran nachteilig, daß sie während des gesamten Betriebszyklus einen Drehschieber im Strömungsquerschnitt aufweisen, der Strömungsverluste verursacht. Weiter ist daran nachteilig, daß durch die dort notwendige Baulänge des Gesamtdrehschiebers Toleranzprobleme auftreten.If you want such suction modules in z. B. use cars, it is disadvantageous that they have a rotary valve in the flow cross-section during the entire operating cycle, which causes flow losses. A further disadvantage is that tolerance problems occur due to the overall length of the rotary valve that is necessary there.

Man könnte nun das ganze Bauteil aus Guß herstellen. Dies ist aber einmal kostenaufwendig in der Herstellung, es würde das Saugmodul verteuern. Zum anderen würde es das Gewicht erhöhen.The entire component could now be made from cast iron. However, this is costly to manufacture, it would make the suction module more expensive. Second, it would increase weight.

Es ist somit Aufgabe der Erfindung, ein Saugmodul der eingangs genannten Art dahingehend zu verbessern, daß ein einfach zu erzeugendes, leicht zu montierendes und zuverlässig arbeitendes billiges Saugmodul entsteht.It is therefore an object of the invention to improve a suction module of the type mentioned at the outset in such a way that an inexpensive suction module which is simple to produce, easy to assemble and reliably works is produced.

Erfindungsgemäß wird diese Aufgabe dadurch gelöst, daß der Ansaugtrakt wenigstens zwei Saugrohröffnungen aufweist und wenigstens eine Saugrohröffnung des Ansaugtraktes mit unveränderbarem Querschnitt in die Brennkraftmaschine führt und wenigstens eine andere Saugrohröffnung desselben Ansaugtrakts mittels eines Drehschiebers mit der Brennkraftmaschine verbunden ist.According to the invention, this object is achieved in that the intake tract has at least two intake manifold openings and at least one intake manifold opening of the intake tract with an unchangeable cross section leads into the internal combustion engine and at least one other intake manifold opening of the same intake tract is connected to the internal combustion engine by means of a rotary valve.

Im Betriebszuständen, in denen nur ein Teil des Saugrohrquerschnitts benötigt wird, behindert kein zusätzliches Teil den Strömungwiderstand, was einem verminderten Verbrauch entgegenkommt. In Betriebszuständen, in denen ein erweiterter Querschnitt erforderlich ist, wird über den zuschaltbaren Drehschieber die Querschnittsfläche optimal angepaßt.In operating states in which only a part of the intake manifold cross-section is required, no additional part hinders the flow resistance, which helps reduce consumption. In operating states in which an enlarged cross-section is required, the cross-sectional area can be optimally adjusted using the rotary valve that can be activated.

Eine vorteilhafte Weiterbildung sieht vor, daß der Drehschieber im Flansch des Saugmoduls angeordnet ist. Diese Anordnung erleichtert sowohl die Montage als auch die Wartung der Drehschiebereinheiten. Weiter läßt diese Variante unterschiedliche Materialkombinationen zwischen Zylinderkopf, Flansch und Drehschieber zu.An advantageous development provides that the rotary valve is arranged in the flange of the suction module. This arrangement facilitates both assembly and maintenance of the rotary valve units. This variant also allows different material combinations between the cylinder head, flange and rotary valve.

Weiterhin kann man vorteilhafterweise vorsehen, daß der Drehschieber symmetrisch zu seiner Längsachse ist. Durch die symmetrische Ausgestaltung ergeben sich Vorteile sowohl hinsichtlich der Herstellung als auch im Betrieb des Drehschiebers.Furthermore, one can advantageously provide that the rotary valve is symmetrical to its longitudinal axis. The symmetrical design results in advantages both with regard to the manufacture and the operation of the rotary valve.

Eine weitere vorteilhafte Weiterbildung sieht vor, daß der Drehschieber schwimmend gelagert ist. Hinsichtlich der Frage der Einbautoleranzen sowie der Schallerzeugung bzw. -übertragung ergeben sich in der beschriebenen Variante deutliche Vorteile.Another advantageous development provides that the rotary slide valve is floating. With regard to the question of installation tolerances and sound generation or transmission, there are clear advantages in the described variant.

Eine vorteilhafte Weiterbildung ergibt sich, wenn der Drehschieber und/oder das Saugmodul aus Kunststoff besteht. Durch die Ausführung in Kunststoff lassen sich klare Gewichts- und Kostenvorteile erzielen.An advantageous further development results if the rotary slide valve and / or the suction module consists of plastic. The design in plastic enables clear weight and cost advantages to be achieved.

Zusätzliche vorteilhafte Weiterbildungen ergeben sich aus den restlichen Unteransprüchen.Additional advantageous further developments result from the remaining subclaims.

Diese und weitere Merkmale von bevorzugten Weiterbildungen derThese and other features of preferred developments of the

Erfindung gehen außer aus den Ansprüchen auch aus der Beschreibung und den Zeichnungen hervor, wobei die einzelnen Merkmale jeweils für sich allein oder zu mehreren in Form von Unterkombinationen bei der Ausführungsform der Erfindung und auf anderen Gebieten verwirklicht sein und vorteilhafte sowie für sich schutzfähige Ausführungen darstellen können, für die hier Schutz beansprucht wird.In addition to the claims, the invention also emerge from the description and the drawings, the individual features being implemented individually or in groups in the form of sub-combinations in the embodiment of the invention and in other fields and can represent advantageous and protectable embodiments , for which protection is claimed here.

In der Zeichnung zeigen:

  • Figur 1 eine Draufsicht des Saugmoduls,
  • Figur 2 ein Schnitt entlang der Linie A - A,
  • Figur 3 ein Schnitt durchs Drehschiebergehäuse,
  • Figur 4 eine Draufsicht in Pfeilrichtung X,
  • Figur 5 Drehschieber, schwimmend gelagert,
  • Figur 6 Drehschieber, ballig gelagert.
The drawing shows:
  • FIG. 1 shows a top view of the suction module,
  • FIG. 2 shows a section along the line AA,
  • FIG. 3 shows a section through the rotary valve housing,
  • FIG. 4 shows a plan view in the direction of the arrow X,
  • FIG. 5 rotary slide valve, floating,
  • Figure 6 rotary valve, crowned.

Das Saugmodul besteht, wie in Figur 1 dargestellt, aus Saugrohr 1, Flansch 2 und Unterdruckdose 3. Die Integration von Drehschieber 4 wird im Schnitt sowohl in Figur 2 als auch in Figur 3 in seiner Einbauposition im Flansch 2 dargestellt.As shown in FIG. 1, the suction module consists of suction pipe 1, flange 2 and vacuum socket 3. The integration of rotary valve 4 is shown in section in FIG. 2 as well as in FIG. 3 in its installation position in flange 2.

Die Symmetrie bezüglich der Längsachse wird besonders in Figur 3 deutlich. Der Drehschieber 4 reguliert lediglich den Strömungsquerschnitt einer der beiden Saugrohröffnungen 5, so daß die andere Saugrohröffnung 6 stets ohne strömungswiderstandserhöhende Elemente das Verbrennungsgemisch weiterleiten kann. Die Trennung der zugehörigen Saugrohröffnungen 5 und 6 im Flanschbereich wird in Figur 3 deutlich. Diese Trennung der Öffnungen sowie das bedarfsweise Öffnen bzw. Schließen durch Drehschieber 4 garantiert eine optimale Verbrennung in jedem Betriebszustand sowie die daraus resultierende Verringerung des Kraftstoffverbrauchs. Der Einsatz magerer Mischungen wird so in allen Betriebszuständen möglich. Die Verwendung von Kunststoff als Werkstoff für Saugrohr 1, Flansch 2 und Drehschieber 4 reduziert das Gewicht sowie die Herstellkosten.The symmetry with respect to the longitudinal axis is particularly clear in Figure 3. The rotary valve 4 only regulates the flow cross section of one of the two intake pipe openings 5, so that the other intake pipe opening 6 can always pass on the combustion mixture without elements which increase the flow resistance. The separation of the associated intake manifold openings 5 and 6 in the flange area is clear in Figure 3. This separation of the openings and the need to open or close them by means of rotary valve 4 guarantees optimal combustion in any operating state and the resultant resulting reduction in fuel consumption. The use of lean mixtures is possible in all operating conditions. The use of plastic as the material for intake manifold 1, flange 2 and rotary valve 4 reduces the weight and the manufacturing costs.

Die schwimmende Lagerung von Drehschieber 4 erfolgt mittels einer mit Gleitmitteln dotierten Kunststoffbuchse 8 auf der Drehschieberachse 7 sowie des dazugehörigen O-Rings 9, der in einer Gehäusevertiefung Platz findet.The floating mounting of rotary valve 4 takes place by means of a plastic bushing 8 doped with lubricants on the rotary valve axis 7 and the associated O-ring 9, which is accommodated in a housing recess.

In einem weiteren Ausführungsbeispiel wird, wie in Figur 6 dargestellt, die Drehschieberachse 7 ballig ausgeführt und die Werkstoffkombination Achse/Lagerbuchse mit gleitmitteldotiertem Kunststoff gewählt.In a further exemplary embodiment, as shown in FIG. 6, the rotary slide axis 7 is made spherical and the material combination axis / bearing bush is selected with plastic doped with lubricant.
