Die hauptsächlichsten Mängel der Petroleumpumpen bei Petroleumkraftmaschinen beruhen in der Abdichtung des Pumpenkolbens, bezw. bestehen in dem Undichtwerden der Ventile, sobald nur die kleinsten Schmutztheile zwischen die Sitzflächen der letzteren gelangen. Die in beiliegender Zeichnung dargestellte Pumpe vermeidet jene Uebelstände durch die Anwendung eines besonderen Raumes zur Aufnahme von "Glycerin, so dafs der Pumpenkolben nur mit letzterem in Berührung kommen kann, und durch die Anwendung eines Schiebers, dessen Bewegung von einer unrunden Scheibe aus erfolgt, die zugleich zur Bewegung des Pumpen-. kolbens dient.The main shortcomings of petroleum pumps reside in petroleum engines in the seal of the pump piston, respectively. consist in the leaking of the valves, as soon as only the smallest pieces of dirt get between the seats of the latter. In the The pump shown in the accompanying drawing avoids those inconveniences caused by the application a special space for receiving "glycerine, so that the pump piston only with the latter can come into contact, and through the use of a slide, whose Movement takes place from a non-circular disc, which at the same time moves the pump. piston is used.
A ist der Pumpenkörper, B der Kolben, C der Schieber, D der Raum zur Aufnahme von Glycerin, F die unrunde Scheibe zur Bewegung von Schieber und Kolben, G ein Hebel mit Rolle g zur Uebertragung der Bewegung des Nockens auf den Pumpenkolben, H ein Doppelhebel mit Drehpunkt in u zur Uebertragung der Bewegung auf den Schieber; die Hebel G und H werden durch aus der Zeichnung nicht ersichtliche Federn gegen die Nockenscheibe gedrückt. A is the pump body, B the piston, C the slide, D the space to hold glycerine, F the non-circular disk for moving the slide and piston, G a lever with a roller g for transmitting the movement of the cam to the pump piston, H a Double lever with pivot point in u for transferring the movement to the slide; the levers G and H are pressed against the cam disk by springs which cannot be seen in the drawing.
In der gezeichneten Lage ist der Auslafskanal α durch eine Mulde m im Schieber C mit dem Kanal b verbunden, und während nun die unrunde Scheibe F in der Pfeilrichtung bewegt wird, findet ein Heben der Rolle g und damit des Hebels G sowie des Pumpenkolbens B statt. Hierbei wird aus dem Raum D eine geringe Menge des über der Glycerinschicht lagernden Petroleums durch Kanal b und Mulde m in den Abflufskanal a gedrückt. Während dieser Zeit bleibt der Schieber C unbeweglich in der gezeichneten Lage stehen, wie sich aus der Betrachtung der Fläche x-\ der Scheibe F ohne Weiteres ergiebt. Hat Punkt χ die Rolle g erreicht, dann ist Punkt \ an Rolle h angelangt, und jetzt wird die Rolle h auf der Fläche \-v ablaufen, sich dabei nach links und den Schieber nach rechts bewegend, derart, dafs die Mulde m den Einlafskanal 0 in Verbindung mit dem Kanal b bringt. Mittlerweile ist die Fläche x-\ unter der Rolle g hergelaufen, ohne den Pumpenkolben im Geringsten zu bewegen. Weiterhin liegt die Rolle h auf der centrischen Fläche v-w auf; der Schieber bleibt daher in seiner Stellung nach rechts unbeweglich stehen, dagegen wird die Rolle g mit Hebel und Pumpenkolben auf der Fläche ^-ν sinken und der Kolben bei dieser Abwärtsbewegung eine kleine Menge Petroleum durch Kanal o, Mulde m und Kanal b im Raum D ansaugen. Zur Verstellung des Hubes vom Pumpenkolben B dient die Schraube S1 und der feste Anschlag T in der Weise, dafs bei einem Niederschrauben von S die Rolle mit Hebel und Kolben in mehr oder minder grofsem Abstand von der Fläche v-w der unrunden Scheibe gehalten wird.In the position shown, the outlet channel α is connected to the channel b by a depression m in the slide C , and while the non-circular disk F is now being moved in the direction of the arrow, the roller g and thus the lever G and the pump piston B are lifted . Here, a small amount of the petroleum stored above the glycerine layer is pressed from space D through channel b and trough m into drain channel a. During this time, the slide C remains immovable in the position shown, as is readily apparent from the consideration of the area x- \ of the disk F. When point χ has reached roll g , point \ has reached roll h , and now roll h will run down on surface \ -v , moving to the left and the slide to the right, in such a way that the trough m opens the inlet channel 0 in connection with channel b . In the meantime, the area x- \ has run under the roller g without moving the pump piston in the slightest. Furthermore, the roller h rests on the centric surface vw ; the slide therefore remains immovable in its position to the right, on the other hand the roller g with lever and pump piston will sink on the surface ^ -ν and the piston will sink a small amount of petroleum through channel o, trough m and channel b in space D during this downward movement suck in. The screw S 1 and the fixed stop T serve to adjust the stroke of the pump piston B in such a way that when S is screwed down, the roller with lever and piston is kept at a more or less large distance from the surface vw of the non-circular disk.
Der Kolben befindet sich vollständig in Ruhe, wenn der Schieber bewegt wird, und umgekehrt der Schieber feststeht, wenn der Kolben aufwärts bezw. abwärts geht. Das Glycerin im Raum D steht mit dem Kolben durch die Bohrung i an der tiefsten Stelle des Raumesin Verbindung. DieLedermanschettenM, welche bei den bisherigen Einrichtungen unterThe piston is completely at rest when the slide is moved, and conversely, the slide is fixed when the piston is up and respectively. going down. The glycerine in space D is connected to the piston through bore i at the lowest point of the space. The leather cuffs M, which are available from the previous institutions under
der Einwirkung des Petroleums standen und selbst im präparirten Zustande nach kurzer Zeit hart und brüchig bezw. für Petroleum durchlässig wurden, stehen hier vollständig in Glycerin, welches diese Manschetten dauernd geschmeidig erhält. Da das specifische Gewicht des Glycerins gröfser ist als das des Petroleums, so wird letzteres über ersterem, wie gezeichnet, stehen bleiben.were exposed to the action of petroleum and even in the prepared state after a short time hard and brittle or permeable to petroleum are completely in here Glycerine, which keeps these sleeves supple at all times. As the specific gravity of glycerine is greater than that of petroleum, the latter is over the former, as drawn, stop.
