Description

Die Erfindung betrifft eine Verbesserung der den Gegenstand des Patents 582 479 bildenden Vorrichtung zum selbsttätigen völligen Absperren der Brennstoffzufuhr zum Antriebsmotor von Kraftfahrzeugen zur Verminderung des Brennstoffverbrauches.The invention relates to an improvement on the subject of patent 582,479 Device for automatic complete shut-off of the fuel supply to the drive motor of motor vehicles to reduce fuel consumption.

Bei der Vorrichtung nach dem Hauptpatent wird eine im Brennstoffsaugrohr des Motors vorgesehene Absperrklappe durch einen unter Federwirkung stehenden Kolben verstellt, dem das Betriebsmittel (Saugzug des Motors bzw. atmosphärische Luft) je nach der Stellung eines elektromagnetisch gesteuerten Ventils zugeführt wird, wobei der Erregerstrom für das Elektroventil einerseits über einen mittels des Gasfußhebels verstellbaren Schalter, anderseits über einen von der Drehzahl des Motors abhängigen selbsttätigen Schalter geleitet ist.In the device according to the main patent is one in the fuel suction pipe of the Motor-provided butterfly valve by a piston under spring action adjusted to which the equipment (induced draft of the engine or atmospheric air) depending is supplied after the position of an electromagnetically controlled valve, the Excitation current for the electrovalve on the one hand via an adjustable by means of the accelerator pedal Switch, on the other hand via an automatic depending on the speed of the engine Switch is directed.

ao Diese Vorrichtung kann die ihr zugewiesene Aufgabe, nämlich die Verringerung des Brennstoffverbrauches bei entsprechenden Betriebsbedingungen, nur dann erfüllen, wenn das im Brennstoffsaugrohr befindliche Absperrorgan völlig dicht schließt.ao This device can do its assigned task, namely reducing of the fuel consumption under the corresponding operating conditions, only if the one located in the fuel suction pipe The shut-off element closes completely tightly.

Mancherlei Umstände, beispielsweise dieVarious circumstances, such as the

Erwärmung des Absperrgliedes und des Brennstoffsaugrohrs beim Lauf des Motors, können Anlaß geben, daß das Absperrglied nicht völlig dicht schließt.Heating of the shut-off element and the fuel suction pipe when the engine is running, can give the reason that the shut-off element does not close completely tightly.

Um auch unter diesen Verhältnissen keinen unwirtschaftlichen Brennstoffverbrauch in Kauf nehmen zu müssen, ist gemäß der Erfindung die Vorrichtung nach dem Hauptpatent so ausgebildet, daß bei geschlossenem Absperrglied Zusätzluftöffnungen zwischen diesem und dem Motor freigegeben werden, wobei die Vorrichtung, die das Absperrglied steuert, auch die Steuerung dieser Zusatzluftöffnungen mittels eines Schiebers o. dgl. überwacht. Die Anwendung von Zusatzluftöffnungen an sich zur Vermeidung von unwirtschaftlichem Brennstoffverbrauch ist bereits bei Vorrichtungen, die 'des besonderen, dicht schließenden Absperrgliedes ermangeln, in Vorschlag gebracht worden.In order to avoid uneconomical fuel consumption in To have to buy is, according to the invention, the device according to the main patent designed so that additional air openings between this and the engine are released when the shut-off member is closed, the device that controls the shut-off member also controlling these auxiliary air openings monitored by means of a slide or the like. The use of additional air openings in itself to avoid uneconomical fuel consumption is already in devices that 'of the special, lack tight shut-off element, has been proposed.

Im vorliegenden Falle wird diese Maßnahme als zusätzliche Maßnahme in Verbindung mit dem dicht schließenden Absperrglied in Vorschlag gebracht, die nur bei unzulänglicher Wirkung des Absperrgliedes praktische Bedeutung gewinnt.In the present case, this measure is linked as an additional measure brought with the tightly closing shut-off member in proposal, which is only inadequate Effect of the shut-off element gains practical importance.

Auf der Zeichnung ist die Vorrichtung nach der Erfindung schematisch veranschaulicht. In the drawing, the device according to the invention is illustrated schematically.

Am Brennstoffsaugrohr 1, in dem sich die übliche, den für den Leerlauf des Motors in der Verschlußlage erforderlichen Querschnitt freilassende Drosselklappe 2 und die völlig dicht schließende Absperrklappe 5 befinden,On the fuel intake pipe 1, in which the usual one for idling the engine in the closing position required cross-section leaving free throttle valve 2 and the completely tightly closing butterfly valve 5 are located,

ist ein etwa zylindrischer Ansatz 35 angeordnet, der ins Freie führende Bohrungen 36 aufweist. Diese werden durch den Kolbenschieber 8 gesteuert, der mittels des mit Anschlagen versehenen Mitnehmers 37 und der Stange 38 mit dem Absperrglied 5 verbunden ist. Der Kolbenschieber 8 steht unter dem Einfluß einer Feder 39. Der Raum, in dem sich die Feder befindet, steht mittels des Rohres 12 mit dem Brennstoff saugrohr des Motors in Verbindung. In diesem Raum ist ein elektromagnetisch gesteuertes Doppelventil ι ia angeordnet, das einerseits die Verbindung dieses Raumes mit dem Rohr 12, also weiterhin mit dem Brennstoff saugrohr 1, und anderseits mit der Zusatzluftöffnung 40 steuert. Der Erregerstrom für das elektromagnetisch gesteuerte Ventil IIs ist einerseits über den Anker 18 des Elektromagneten 17 geführt, dessen Erregerstrom in Abhängigkeit von der Motordrehzahl (etwa derjenigen der Lichtmaschine 23) geregelt wird, und anderseits über den in Abhängigkeit von der Verstellung des Gasfußhebels 4 betätigten Schalter 20, 25, 26.an approximately cylindrical extension 35 is arranged, which has bores 36 leading into the open. These are controlled by the piston valve 8, which is connected to the shut-off member 5 by means of the driver 37 provided with stops and the rod 38. The piston valve 8 is under the influence of a spring 39. The space in which the spring is located is connected by means of the pipe 12 to the fuel intake pipe of the engine. In this space there is an electromagnetically controlled double valve ι i a , which on the one hand controls the connection of this space with the pipe 12, that is to say still with the fuel intake pipe 1, and on the other hand with the additional air opening 40. The excitation current for the electromagnetically controlled valve II s is conducted on the one hand via the armature 18 of the electromagnet 17, the excitation current of which is regulated as a function of the engine speed (e.g. that of the alternator 23), and on the other hand via the actuated depending on the adjustment of the accelerator pedal 4 Switches 20, 25, 26.

Die Wirkungsweise der Vorrichtung ist die folgende:The device works as follows:

Bei schnellfahrendem Fahrzeug gibt die Lichtmaschine 23 einen starken Ladestrom ab, der über 22, die Spule des Elektromagneten 17, Leitung 14 zur Batterie 15 fließt. Der Anker 18 ist daher angezogen. Wird jetzt der Gasfußhebel 4 freigelassen (gezeichnete Lage), so wird der Kontaktklotz 25 an den Kontakt 20 herangelegt. Infolgedessen fließt Strom von der Batterie 15 über 14, 13, die Wicklung 30 des Elektroventils iia, Leitung 16, Anker 18 und Leitung 19, Kontakt.20 und Kontaktklotz 25 zur Masse. Das Elektroventil iia schließt die Zusatzluftöffnung 40 und öffnet die Mündung der Leitung 12. Der Saugzug des Motors -zieht den Kolbenschieber 8 in die gezeichnete Lage, wodurch zunächst die Zusatzluftöffnungen 36 geöffnet werden, worauf der Mitnehmer 37 das Absperrglied 5 schließt. Sinkt die Maschinendrehzahl so weit, daß der Anker 18 des Elektromagneten 17 abfedert, so ist der Erregerstrom des Elektroventils iia unterbrochen. Es steuert unter der Saugwirkung des go Motors um, verschließt das Rohr 12 und öffnet die Zusatzluftöffnung 40. Die Feder schiebt den Kolbenschieber 8 zurück, dieser schließt zunächst die Zusatzluftöffnungen 36, sodann wird der Mitnehmer 37 verschoben, der das Absperrglied S wieder öffnet.When the vehicle is moving at high speed, the alternator 23 emits a strong charging current which flows via 22, the coil of the electromagnet 17, line 14 to the battery 15. The anchor 18 is therefore tightened. If the accelerator pedal 4 is now released (position shown), the contact block 25 is placed against the contact 20. As a result, current flows from the battery 15 via 14, 13, the winding 30 of the solenoid valve ii a , line 16, armature 18 and line 19, Kontakt.20 and contact block 25 to ground. The electrovalve ii a closes the additional air opening 40 and opens the mouth of the line 12. The induced draft of the motor pulls the piston valve 8 into the position shown, whereby the additional air openings 36 are first opened, whereupon the driver 37 closes the shut-off element 5. If the engine speed drops so far that the armature 18 of the electromagnet 17 cushions, the excitation current of the electrovalve ii a is interrupted. It controls under the suction of the go motor, closes the pipe 12 and opens the additional air opening 40. The spring pushes the piston valve 8 back, this first closes the additional air openings 36, then the driver 37 is moved, which opens the shut-off member S again.
