Description

Die Erfindung betrifft einen Vergaser mit einem an der engsten Stelle eines Venturikanals angeordneten Mischrohr, wobei in einer etwa durch die Austrittsmündung des Mischrohres gehenden, senkrecht zur Achss des Venturikanals ausgerichteten Ebene zwei Schieber zur Veränderung des Durchflußquerschnitts gegensinnig verschwenkbar sind.The invention relates to a carburetor with a mixing tube arranged at the narrowest point of a venturi channel, wherein in a plane going approximately through the outlet mouth of the mixing tube and oriented perpendicular to the axis of the venturi channel, two slides can be pivoted in opposite directions to change the flow cross section.

Ein Vergaser dieser Art ist in der DE-A-2 714 507 und der entsprechenden US-A-4 206 158 beschrieben. Der Venturikanal hat einen im wesentlichen rechteckförmigen Querschnitt. Bei Bewegung der Schieber verändert sich das Verhältnis der Rechteckseiten sehr stark, so daß sich die Strömungsgeometrie stark ändert.A carburetor of this type is described in DE-A-2 714 507 and the corresponding US-A-4 206 158. The venturi channel has an essentially rectangular cross section. When the slide moves, the ratio of the sides of the rectangle changes very greatly, so that the flow geometry changes greatly.

Aufgabe der Erfindung ist die Sicherstellung gleicher Strömungsgeometrie und damit gleichbleibender Gemischaufbereitung bei allen Durchflüssen.The object of the invention is to ensure the same flow geometry and thus constant mixture preparation at all flows.

Diese Aufgabe wird nach der Erfindung dadurch gelöst, daß als Schieber parallel zueinander ausgerichtete Walzen gegenläufig zueinander drehbar angeordnet sind, deren zylindrische Umfangsflächen einander berühren und die jeweils einander gegenüberliegend eine in Umfangsrichtung auslaufende Rinne mit halbkreisförmigem Querschnitt aufweisen.This object is achieved according to the invention in that rollers which are aligned parallel to one another and are arranged so as to be rotatable in opposite directions to one another, the cylindrical peripheral surfaces of which touch one another and which in each case have a channel with a semicircular cross-section which runs out in the circumferential direction.

Die Erfindung unterscheidet sich insofern vom Stand der Technik, als durch die Profile der Walzen eine Änderung des Durchflußquerschnitts jeweils konzentrisch zur Mündung des Mischrohres erfolgt. Hierdurch erzielt man eine im wesentlichen gleichbleibende Strömungsgeometrie an der Mündung des Mischrohres, so daß eine gleichbleibende Gemischbildung gewährleistet ist.The invention differs from the prior art in that the profiles of the rollers change the flow cross section in each case concentrically to the mouth of the mixing tube. This results in a substantially constant flow geometry at the mouth of the mixing tube, so that a constant mixture formation is ensured.

Ein jeweils kreisförmiger Durchflußquerschnitt ist dadurch gewährleistet, daß die Rinne jeweils ein Segment mit halbkreisförmigem Querschnitt und mit einem sichelförmigen, in Umfangsrichtung auslaufenden Abschnitt ist. Der Querschnitt behält im wesentlichen die Kreisform bei und ändert sich nur in die ähnliche Ellipsenform.A circular flow cross-section is ensured in that the channel has a segment with a semi-circular one Cross section and with a crescent-shaped, tapering in the circumferential direction. The cross section essentially retains the circular shape and only changes to the similar elliptical shape.

Die gegenläufige Verstellung der Walzen ist dadurch sichergestellt, daß die Walzen miteinander kämmende Zahnräder tragen.The opposite adjustment of the rollers is ensured in that the rollers carry meshing gears.

Eine Dosierung der Kraftstoffzufuhr entsprechend dem Durchflußquerschnit ist dadurch sichergestellt, daß das Mischrohr in der Umfangsfläche einer Stellkammer mündet, in der ein drehbarer Stellkolben mit abgeschrägter Kopffläche angeordnet ist, der bei seiner Drehung die Austrittsöffnung des Mischrohres absperrt.A metering of the fuel supply in accordance with the flow cross-section is ensured in that the mixing tube opens into the circumferential surface of an actuating chamber in which a rotatable actuating piston with an inclined head surface is arranged, which, when it rotates, blocks the outlet opening of the mixing tube.

Die Kraftstoffzufuhr ist an den Durchflußquerschnitt dadurch gekoppelt, daß ein an dem Stellkolben sitzendes Stirnrad mit dem Zahnrad einer Walze in Eingriff ist.The fuel supply is coupled to the flow cross section in that a spur gear seated on the actuating piston engages with the gear wheel of a roller.

Eine Ausführungsform der Erfindung wird im folgenden unter Bezugnahme auf die anliegenden Zeichnungen erläutert, in denen darstellen:

  • Fig. 1 einen Vergaser in der Ansicht,
  • Fig. 2 einen Schnitt nach der Linie II-II in Fig. 1,
  • Fig. 3 eine Draufsicht zu Fig. 1, teilweise aufgebrochen und
  • Fig. 4 einen Schnitt nach der Linie IV-IV in Fig. 3.
An embodiment of the invention is explained below with reference to the accompanying drawings, in which:
  • 1 shows a carburetor,
  • 2 shows a section along the line II-II in FIG. 1,
  • Fig. 3 is a plan view of FIG. 1, partially broken away and
  • 4 shows a section along the line IV-IV in FIG. 3rd

Der Vergaser 1 ist ein sogenannter Venturivergaser mit einem Venturikanal 2 und einem koaxial in den Venturikanal mündenden Mischrohr 3. Innerhalb einer senkrecht zur Achse des Venturikanals 2 ausgerichteten Ebene, die etwa durch die Austrittsmündung des Mischrohres 3 geht, sind parallel zueinander zwei Walzen 4 drehbar angeordnet, die mit Zahnrädern 5 ineinander eingreifen, so daß sich die Walzen 4 entsprechend den Eingriff der Zahnräder 5 gegensinnig zueinander drehen können. Eine Walze 4 ist über einen radialen Arm 19 mit einem Zugelement 6 eines Gaszuges und einer Rückstellfeder 7 gekoppelt. Entsprechend der Betätigung des Zugelementes 6 werden die Walzen 4 gegensinnig zueinander verschwenkt.The carburetor 1 is a so-called venturi gasifier with a venturi channel 2 and a mixing tube 3 opening coaxially into the venturi channel. Within a plane oriented perpendicular to the axis of the venturi channel 2, which goes approximately through the outlet mouth of the mixing tube 3, two rollers 4 are rotatably arranged parallel to one another , which engage with each other with gear wheels 5, so that the rollers 4 can rotate in opposite directions relative to the engagement of the gear wheels 5. A roller 4 is coupled via a radial arm 19 to a tension element 6 of a throttle cable and a return spring 7. According to the actuation of the tension element 6, the rollers 4 are pivoted in opposite directions to one another.

Die Walzen 4 weisen symmetrisch zueinander ausgerichtete Rinnen 8 auf. Jede Rinne 8 ist ein Segmentausschnitt mit halbkreisförmigem Querschnitt, wobei die RinnenachQe senkrecht kreuzend zur Achse der betreffenden Walze 4 ausgerichtet ist. Jede Rinne 8 läuft an einem Ende in Umfangsrichtung in einen sichelförmigen Abschnitt 9 aus. Die Rinnen 8 bilden in der in Fig. 4 dargestellten Ausrichtung einen Kanal mit kreisförmigem Querschnitt in Verlängerung des Einlauftrichters 10 des Venturikanals 2. Zentrisch innerhalb dieses Kanals mündet das Mischröhr 3. An den Kanal schließt sich in Üblicher Weise der DJffusor 11 an. In den Fig. 3 und 4 ist in ausgezogenen Linien die Stellung der Walzen für den größten Durchflußquerschnitt und in strichpunktierten Linien für den kleinsten Durchflußquerschnitt angegeben.The rollers 4 have channels 8 which are aligned symmetrically to one another. Each trough 8 is a segment cutout with a semicircular cross section, the trough being aligned perpendicular to the axis of the relevant roller 4 according to Q e. Each trough 8 ends at one end in the circumferential direction in a sickle-shaped section 9. The channels 8 in the orientation shown in FIG. 4 form a channel with a circular cross-section in the extension of the inlet funnel 10 of the venturi channel 2. The mixing tube 3 opens centrally within this channel. The DJf connects to the channel in the usual way fusor 11. 3 and 4, the position of the rollers for the largest flow cross-section and in dash-dotted lines for the smallest flow cross-section is indicated in solid lines.

Entsprechend der Betätigung des Zugelementes 6 werden die Walzen 4 gegeneinander verschwenkt. In der in den Fig. 3 und 4 in ausgezogenen Linien eingezeichneten Stellung der Walzen ist der Durchflußquerschnitt des Vergasers am größten und kreisförmig. Wenn das Zugelement 6 unbetätigt ist, wird die Rückstellfeder 7 wirksam. Entsprechend der Drehung der Walzen ergibt sich ein ovalförmiger, sich verkleinernder Querschnitte in dem zentral das Mischrohr liegt. Die auslaufenden Abschnitte 9 der Rinne 8 stellen bei kleinstem Durchflußquerschnitt wieder einen kreisförmigen Querschnitt sicher, wie in strichpunktierten Linien angegeben. Entsprechend der Drehung des Walzen wird der Querschnitt des zentralen Kanals kontinuierlich kleiner. Allerdings ist der Querschnitt immer zentrisch um die Mündung des Mischrohres 3. Infolgedessen sind die Strömungsverhältnisse und damit die Gemischbildung immer gleich.According to the actuation of the tension element 6, the rollers 4 are pivoted against each other. In the position of the rollers shown in solid lines in FIGS. 3 and 4, the flow cross section of the carburetor is largest and circular. If the tension element 6 is not actuated, the return spring 7 becomes effective. Corresponding to the rotation of the rollers, there is an oval-shaped, decreasing cross-section in which the mixing tube lies centrally. The tapering sections 9 of the channel 8 again ensure a circular cross-section with the smallest flow cross-section, as indicated by dash-dotted lines. The cross-section of the central channel continuously decreases in accordance with the rotation of the rollers. However, the cross section is always centered around the mouth of the mixing tube 3. As a result, the flow conditions and thus the mixture formation are always the same.

Das Mischrohr 3 ist an eine Austrittsöffnung 12 in der Umfangswandung einer Stellkammer 13 angeschlossen. Innerhalb der Stellkammer 13 ist ein Stellkolben 14 drehbar angeordnet, der eine abgeschrägte Kopffläche 15 aufweist. Der Stellkolben 14 trägt am Ende ein Stirnrad 16, das mit einem Zahnrad 5 einer Walze 4 kämmt, damit der Stellkolben 14 synchron mit der Drehung der Walzen 4 verschwenkt wird. In die Stellkammer 13 reicht ein Rohr 17, das in eine Schwimmerkammer 18 eintaucht und über das der Kraftstoff zufließt. Die Austrittsöffnung 12 wird entsprechend der Drehung der Walzen 4 und der Drehung des Stellkolbens 14 partiell geöffnet und geschlossen, so daß dadurch eine Dosierung der Kraftstoffzufuhr entsprechend der wirksamen Öffnung des Venturikanals 2 erfolgt.The mixing tube 3 is connected to an outlet opening 12 in the peripheral wall of an actuating chamber 13. An actuating piston 14 is rotatably arranged within the actuating chamber 13 and has a bevelled head surface 15. The actuating piston 14 carries at the end a spur gear 16 which meshes with a gear 5 of a roller 4 so that the actuating piston 14 is pivoted synchronously with the rotation of the rollers 4. A tube 17 extends into the actuating chamber 13, which plunges into a float chamber 18 and through which the fuel flows. The outlet opening 12 is partially opened and closed in accordance with the rotation of the rollers 4 and the rotation of the actuating piston 14, so that the fuel supply is metered in accordance with the effective opening of the venturi channel 2.
