Description

Zusatzluftventil für Brennkraftmaschinen Es sind . selbsttätig wirkende Zusatzluftventile bekannt, die nur bei mittleren Unterdrücken in der Ansaugleitung die Zufuhr von Zusatzluft gestatten. Bei diesen zeigte sich der Nachteil, daß sie durch die Verwendung von Ventilen, Kolben, Federn u. dgl. verhältnismäßig teuer in der Herstellung wurden.Auxiliary air valve for internal combustion engines There are. self-acting Auxiliary air valves known that only operate at medium negative pressures in the intake line allow the supply of additional air. These showed the disadvantage that they relatively expensive due to the use of valves, pistons, springs and the like were in the making.

Durch den Gegenstand der vorliegenden Erfindung wird ein äußerst billig herzustellender Apparat geschaffen, bei dem weder Federn, N'entile noch Kolben Verwendung finden.The subject matter of the present invention makes one extremely inexpensive Apparatus to be produced was created in which neither springs, N'entile nor pistons were used Find.

Der Apparat besteht im wesentlichen aus einem elastischen, z. B. aus -Gummi hergestellten Hohlkörper, der durch zwei, z. B. gleichfalls aus Gummi bestehende Membranen abgeschlossen wird, die zusammen in Wechselwirkung stehen.The apparatus consists essentially of an elastic, e.g. B. off -Rubber made hollow body, which is through two, z. B. also made of rubber Membranes is completed, which interact together.

Die Zeichnung stellt ein Ausführungsbeispiel der Erfindung dar.The drawing shows an embodiment of the invention.

Abb. t zeigt den Querschnitt des Apparates in Ruhestellung, Abb. 2 beim Leerlauf, Abb. 3 bei mittlerem ,Unterdruck in der Ansaugleitung.Fig.t shows the cross section of the apparatus in the rest position, Fig. 2 when idling, Fig. 3 with medium, negative pressure in the suction line.

In Abb. i ist h ein z. B. aus Gummi gefertigter Hohlkörper mit der Kammer a. Die Kammer a ist begrenzt von der Membran m, die bei c durchbohrt ist, und von der gleichfalls als stärkere Membran ausgebildeten Außenwand e. In die Außenwand e ist die Stellschraube s eingesetzt, die in einen kugelförmigen Teil f ausläuft. Der elastische Hohlkörper ist auf der Befestigungsplatte i befestigt.. Die Befestigungsplatte i trägt gleichfalls eine Stellschraube t mit kugelförmigem. Ansatz h und weist außerdem die Luftlöcher o auf. Das Anschlußrohr y verbindet die Kammer a mit dem Ansaugrohr g.In Fig. I, h is a z. B. made of rubber hollow body with the Chamber a. The chamber a is bounded by the membrane m, which is pierced at c, and from the outer wall e, which is also designed as a stronger membrane. In the outer wall e the adjusting screw s is inserted, which ends in a spherical part f. The elastic hollow body is attached to the mounting plate i .. The mounting plate i also carries an adjusting screw t with a spherical. Approach h and also has the air holes o. The connecting pipe y connects the chamber a with the suction pipe G.

Die Wirkungsweise ist nun folgende: Beim Anlassen des Motors vermittels Kurbel oder Anlasser ist der Unterdruck im Ansaugrohr so gering, daß eine Betätigung der Membranen m und e nicht stattfinden kann. Springt der Motor an und läuft er im Leerlauf, so wird durch den hohen Unterdruck die widerstandsfähigere Membran e angehoben. Dabei verschließt die Stellschraube s mit ihrem kugelförmigen Teil f die Öffnung c der schwächeren Membran na und preßt diese gegen die Stellschraube t. Die Zufuhr von Zusatzluft beim Leerlauf ist, wie aus Abb. 2 zu erkennen, damit ausgeschlossen. Läßt der Unterdruck nach, so federt die Membran e zurück, die Membran m wird etwas angehoben, hebt sich damit von der Stellschraube t ab und gibt somit die Zufuhr von Zusatzluft frei, wie das in Abb. 3 dargestellt ist.The mode of operation is now as follows: When starting the engine by means of Crank or starter, the negative pressure in the intake manifold is so low that it can be actuated the membranes m and e cannot take place. The engine starts and runs When idling, the high negative pressure makes the membrane more resistant e raised. The adjusting screw s closes with its spherical part f the opening c of the weaker membrane na and presses it against the adjusting screw t. The supply of additional air when idling is, as can be seen from Fig. 2, with it locked out. If the negative pressure decreases, the membrane e springs back, the membrane m is raised a little, so it is lifted off the adjusting screw t and thus gives the supply of additional air freely, as shown in Fig. 3.
