Description
Durch Auspuffgase betriebene Förderpumpe Die Erfindung betrifft eine durch Auspuffgase eines Verbrennungsmotors betriebene Förderpumpe zum Fördern von flüssigen oder gasförmigen Medien, die an die unter Druck stehende Abgasleitung mit ihrer Antriebsseite anschließbar ist, mit mindestens einem Einlaß-und einem Auslaßventil für die Abgase und mit mindestens einem Einlaß- und einem Auslaßventil für das zu fördernde Medium. Exhaust Gas Operated Feed Pump The invention relates to a feed pump operated by the exhaust gases of an internal combustion engine to deliver liquid or gaseous media connected to the pressurized exhaust pipe can be connected with its drive side, with at least one inlet and one Outlet valve for the exhaust gases and with at least one inlet and one outlet valve for the medium to be funded.
Es.sind bereits Pumpen der eingangs genannten Art bekannt, die als doppelt wirkende Pumpen ausgebildet sind und bei denen die Steuerung des Ein- und Auslasses für die Abgase durch Klappenventile oder Schiebeventile erfolgt. Diese bekannten Pumpen sind beim Betrieb einer starken Verschmutzung durch die in den Abgasen enthaltenen Verbrennungsrückstände ausgesetzt. Ihre Funktionssicherheit ist daher bei längerem Betrieb nicht gewährleistet. Dieser Nachteil soll vermieden werden.There are already pumps of the type mentioned that are known as double-acting pumps are designed and in which the control of the input and Outlet for the exhaust gases takes place through flap valves or slide valves. These known pumps are in the operation of a heavy pollution by in the Exposed combustion residues contained in exhaust gases. Your functional reliability is therefore not guaranteed in the event of prolonged operation. This disadvantage should be avoided.
Diese Aufgabe wird bei einer Förderpumpe der eingangs genannten Art erfindungsgemäß dadurch gelöst, daß das Einlaß- und das Auslaßventil für die Abgase einen gemeinsamen, um eine Drehachse kippbaren Schließkörper aufweist, der zwei stabile Kippstellungen, einmal am Einlaß und einmal am Auslaß, aufweist, wobei die Umschaltung des Schließkörpers durch zwei entgegengesetzt wirkende Anschläge an von den Auspuffgasen bewegten Förderteilen der Pumpe bewirkt wird.This task is carried out with a feed pump of the type mentioned at the beginning according to the invention achieved in that the inlet and outlet valve for the exhaust gases has a common closing body which can be tilted about an axis of rotation and which has two stable tilted positions, once at the inlet and once at the outlet, with the Switching of the closing body by two oppositely acting stops is effected by the exhaust gases moving conveying parts of the pump.
Die Figur zeigt einen Schnitt durch ein Ausführungsbeispiel der Erfindung.The figure shows a section through an embodiment of the invention.
In der Figur ist mit 1 die Abgasleitung des Verbrennungsmotors bezeichnet. Die Pumpe weist einen Einlaß 2 und einen Auslaß 3 für die Abgase auf. Der Einlaß 2 und der Auslaß 3 sind ventilgesteuert. Die über den Einlaß 2 einströmenden Abgase bewirken bei geschlossenem Auslaß 3, daß sich die Membran 11 entgegen der Kraft der Feder 12 nach oben bewegt. Im gezeigten Beispiel weist die Pumpe einen Niederdruckförderraum 18 und einen Hochdruckförderraum 12 auf. Bei der Bewegung der Membran 11 nach oben wird aus dem Raum 18 über das Auslaßventil 19 gefördert. Der Niederdruckförderteil mit dem Förderraum 18 ist zum Fördern eines Mediums in großer Menge, jedoch geringem Druck geeignet. Der Hochdruckförderteil mit dem Förderraum 22 ist zur Förderung geringer Mengen bei hohem Druck geeignet. Beim Bewegen der Membran 11 nach oben wird aus dem Raum 22 über das Auslaßvantil 2;L gefördert. Im Förderraum 22 bewegt sich ein Kolben 21 hin und her.In the figure, 1 denotes the exhaust pipe of the internal combustion engine. The pump has an inlet 2 and an outlet 3 for the exhaust gases. The inlet 2 and the outlet 3 are valve controlled. The exhaust gases flowing in via inlet 2 cause when the outlet 3 is closed that the membrane 11 against the force the spring 12 moves upwards. In the example shown, the pump has a low-pressure pumping chamber 18 and a high pressure delivery chamber 12. When the membrane 11 moves upwards is conveyed from the space 18 via the outlet valve 19. The low pressure conveying part with the conveying space 18 is for conveying a medium in large amounts, but in small amounts Suitable for pressure. The high-pressure delivery part with the delivery space 22 is for delivery suitable for small quantities at high pressure. When moving the membrane 11 upwards is from the space 22 via the outlet valve 2; L promoted. In the delivery room 22 a piston 21 moves back and forth.
Ist der Einlaß 2 verschlossen und der Auslaß 3 geöffnet, dann bewegt sich die Membran 11 unter der Wirkung der Feder 12 nach unten. Gleiches gilt auch für den Kolben 21. Bei dieser Bewegung wird Medium über den Einlaß 20 bzw. über den Einlaß 23 angesaugt.If the inlet 2 is closed and the outlet 3 is open, then it is moved the membrane 11 under the action of the spring 12 downwards. The same also applies for the piston 21. During this movement, medium is via the inlet 20 or via the inlet 23 sucked.
An den von den Auspuffgasen bewegten Förderteilen 11, 21 befindet sich eine Stange 8 mit Anschlägen 9 und 10.Located on the conveying parts 11, 21 moved by the exhaust gases a rod 8 with stops 9 and 10.
Diese Anschläge bewirken ein Umschalten des um die Drehachse 5 kippbaren Schließkörpers 4, der auf diese Weise wechselweise den Einlaß 2 und den Auslaß 3 schließt oder öffnet. Der Schließkörper 4 ist nach Art eines Schnappschalters ausgebildet, so daß zwei stabile Kippstellungen entstehen. In der einen Kippstellung ist der Auslaß 3 verschlossen und der Einlaß. 2 geöffnet, während in der anderen stabilen Kippstellung der Auslaß 3 geöffnet und der Einlaß 2 verschlossen ist. Zu diesem Zweck weist der Schließkörper 4 einen rechtwinkligen Ansatz 6 auf, der sich an einer Feder 7 abstützt, wobei die Feder 7 in den Kippstellungen teilweise entspannt ist.These stops cause a switchover of the tiltable about the axis of rotation 5 Closing body 4, which in this way alternates between inlet 2 and outlet 3 closes or opens. The closing body 4 is designed in the manner of a snap switch, so that two stable tilt positions arise. In the one tilt position is the Outlet 3 closed and the inlet. 2 opened while in the other stable Tilted position the outlet 3 is open and the inlet 2 is closed. To this Purpose, the closing body 4 has a right-angled extension 6, which is at a Spring 7 is supported, the spring 7 being partially relaxed in the tilted positions.
In einer Ausführungsform ist es möglich, daß die Anschläge 9, 10 direkt auf den Schließkörper 4 wirken und dessen Umschaltung gewährleisten. Bevorzugt ist jedoch die gezeigte Ausführungsform, bei welcher ein Steuerhebel 13 vorgesehen ist, der ebenfalls zwei stabile ISippstellungen aufweist. Der Steuerhebel 13 arbeitet also ebenfalls nach Art eines Schnappschalters.In one embodiment it is possible that the stops 9, 10 directly act on the closing body 4 and ensure its switching. Is preferred however, the embodiment shown, in which a control lever 13 is provided, which also has two stable I-tilt positions. The control lever 13 works also like a snap switch.
Er besitzt einen rechtwinklig verlaufenden Ansatz 16, der sich an einer Feder 17 abstützt. Dieser Steuerhebel 13 tritt über Anschläge 14, 15 in Kontakt mit dem Schließkörper 4.He has a right-angled approach 16, the is supported on a spring 17. This control lever 13 occurs via stops 14, 15 in contact with the closing body 4.
In der gezeigten Stellung des Schließkörpers 4 bewirken die über den Einlaß 2 eintretenden Abgase eine Bewegung der Membran 11 nach oben. Kurz vor dem oberen Totpunkt tritt der Anschlag 10 in Kontakt mit dem Steuerhebel 13 und bewegt diesen um die Achse 5 entgegen der Kraft der Feder 17 bis über seine Mittelstellung, wobei dann durch die Feder 17 eine rasche Schwenkbewegung des Hebels 13 erfolgt. Bei dieser Schwenkbewegung tritt der Anschlag 15 in Kontakt mit dem Schließkörper 4, der hierdurch in seine andere Kippstellung bewegt wird, bei welcher der Einlaß 2 abgeschlossen und der Auslaß 3 geöffnet wird. Hierdurch strömen die Abgase aus dem Auslaß 3, so daß die Feder 12 nunmehr die Membran 11 nach unten bewegen kann. Kurz vor Erreichen der Totlage tritt der Anschlag 9 in Kontakt mit dem Steuerhebel 13 und bewegt diesen über seine Mittelstellung, wodurch anschließend der Anschlag 14 in Kontakt tritt mit dem Schließkörper 4 und diesen in die gezeigte Stellung umlegt.In the position shown of the closing body 4, the effect over the Inlet 2 entering exhaust gases a movement of the membrane 11 upwards. Shortly before the At the top dead center, the stop 10 comes into contact with the control lever 13 and moves this around the axis 5 against the force of the spring 17 up to its middle position, a rapid pivoting movement of the lever 13 then takes place through the spring 17. During this pivoting movement, the stop 15 comes into contact with the closing body 4, which is thereby moved into its other tilt position, in which the inlet 2 completed and the outlet 3 is opened. This causes the exhaust gases to flow out the outlet 3, so that the spring 12 can now move the membrane 11 downwards. Shortly before reaching the dead center, the stop 9 comes into contact with the control lever 13 and moves it over its center position, which then causes the stop 14 comes into contact with the closing body 4 and this into the position shown kills.
Um diese Arbeitsweise ausführen zu können, ist es erforderlich, daß die Steuerhebelfeder 17 stärker ausgebildet ist als die Schließkörperfeder 7.In order to be able to carry out this procedure, it is necessary that the control lever spring 17 is made stronger than the closing body spring 7.
