M 136580 KLASSE 46 c. M 136580 CLASS 46 c.
Den Gegenstand der Erfindung bildet eine Weiterbildung der für Petroleumkraftmaschinen bestimmten Speisevorrichtung desPatentsi2o,23 5. Bei dieser Ausführungsform ist die Kugel zum zeitweiligen Absperren der Durchtrittsöffnung der Düse durch einen doppelkegelförmigen Ventilkörper ersetzt, der durch eine Feder gehoben wird. Die verstellbare Stange, auf welcher dieser Doppelkegel ruht, besteht aus einem Rohre, welches den Eintritt des Petroleums in die Kammer vermittelt. Mit dieser Veränderung wird bezweckt: 1. die Anbringung eines Rückschlagventils zwischen dem Einlafs für das Petroleum und dem Petroleumvorrathsbehälter entbehrlich zu machen, 2. eine Wiedereinstellung des Ventils beim Auffüllen des Vorrathsbehälters unnöthig zu machen und 3. einer etwaigen Ueberfluthung des Carburators vorzubeugen.The subject matter of the invention is a development for petroleum engines certain feeding device of the patent i2o, 23 5. In this embodiment, the ball is used to temporarily block the passage opening The nozzle is replaced by a double cone-shaped valve body that is lifted by a spring will. The adjustable rod on which this double cone rests consists of one Pipes that mediate the entry of the petroleum into the chamber. With this change The purpose is: 1. the installation of a check valve to make it unnecessary between the inlet for the petroleum and the petroleum storage container, 2. a readjustment to make the valve unnecessary when filling the storage container and 3. any To prevent flooding of the carburator.
Fig. ι zeigt im senkrechten Schnitt eine solche Speisevorrichtung und Fig. 2 stellt von unten gesehen das untere Ende der Düse dar.Fig. Ι shows such a feed device in vertical section and Fig. 2 represents from seen below represents the lower end of the nozzle.
Das Ventil besteht aus. einem doppelt kegelförmigen Ventilkörpero, derauf einer Schraubenfeder ρ ruht und in der Düse h centrirt ist, und aus der hohlen, verstellbaren Stange k. Der den oberen Ventilsitz bildende untere Theil der Düse h ist mit mehreren Nuthen oder Schlitzen /21 (Fig. 2) ausgestattet, oder es können statt dessen auf der oberen Kegelfläche von 0 radiale Abflachungen vorgesehen sein, so dafs im einen wie im anderen Falle das Petroleum in die Düse treten kann. Der untere Theil des kreiselförmigen Ventilkörpers 0 dient zum Ab- . sperren der Mündungsöffnung der hohlen Stange k. The valve consists of. a double conical valve body o, which rests on a helical spring ρ and is centered in the nozzle h , and from the hollow, adjustable rod k. The lower part of the nozzle h , which forms the upper valve seat, is provided with several grooves or slots / 2 1 (Fig. 2), or instead radial flattenings can be provided on the upper conical surface of 0 , so that in one case as in the other the kerosene can get into the nozzle. The lower part of the gyro-shaped valve body serves to shut off. locking the mouth of the hollow rod k.
Am unteren Theile der Stange k befinden sich mehrere Oeffnungen für den Eintritt des Petroleums aus dem Zuleitungsrohre m, welch' letzteres also nicht mehr wie bei der Speisevorrichtung des Patents 129235 unmittelbar in die Kammer b mündet. Die Dichtung s wird durch die Ueberfallmutter r gesichert. Zur Einstellung der Stange k und zur Regelung des Ventilhebels dient ein Handrad t. On the lower part of the rod k there are several openings for the entry of the petroleum from the supply pipe m, which the latter no longer opens directly into the chamber b as in the feeding device of patent 129235. The seal s is secured by the lock nut r. A hand wheel t is used to adjust the rod k and to regulate the valve lever.
Die Wirkungsweise der Speisevorrichtung ist folgende: Beim Ansaugen des Kolbens wird die biegsame Platte c nach aufwärts bewegt und der kreiseiförmige Ventilkörper ο durch die Wirkung der Feder ρ gehoben. Es wird nun Petroleum durch die Düse h hindurch in die Kammer α gesaugt, wahrend zugleich eine neue Petroleummenge durch Stange k hindurch in die Kammer b eingeführt wird. Nach Beendigung des Saughubes des Kolbens bewegt sich die biegsame Platte c wieder zurück, der Untertheil des kreiseiförmigen Ventilkörpers 0 versperrt die Durchtrittsöffnung des Rohres k, und durch die Rückwirkung der Platte c wird vonThe mode of operation of the feed device is as follows: When the piston is sucked in, the flexible plate c is moved upwards and the circular valve body ο is lifted by the action of the spring ρ. Petroleum is now sucked through the nozzle h into the chamber α , while at the same time a new amount of petroleum is introduced through the rod k into the chamber b . After completion of the suction stroke of the piston, the flexible plate c moves back again, the lower part of the circular valve body 0 blocks the passage opening of the pipe k, and the reaction of the plate c is of
Neuem Petroleum in die Höhe gepumpt und in die Kammer α gedruckt.New kerosene is pumped up and printed into the chamber α.
