KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Zum Betriebe der pneumatischen Regler für Flugmaschinen soll nachstehend beschriebene Druckluftpumpe dienen.To operate the pneumatic controller for flying machines is described below Serve compressed air pump.
Bei den besonderen Bedingungen, die für Maschinen »Schwerer als die Luft« von größter Bedeutung sind, gilt als Erstes größtmögliche Leichtigkeit bei unbedingter Sicherheit der arbeitenden Teile.Given the special conditions that are “heavier than air” for machines, they are of the greatest importance The first thing that matters is the greatest possible ease with absolute security working parts.
Von diesen maßgebenden GesichtspunktenFrom these authoritative points of view
ίο ausgehend, ist bei der Durchbildung dieser Luftpumpe alles das weggelassen worden, was irgendwie zu entbehren war. Die Pumpe ist als Doppelplunger-Luftpumpe mit gemeinsamer Kurbelschleife K ausgebaut, was gedrängteste Bauart ermöglichte und symmetrische Form von der Kurbelwelle W aus nach rechts und links gestattete.ίο starting out, everything that was somehow dispensed with was left out in the creation of this air pump. The pump is designed as a double-plunger air pump with a common crank loop K , which enabled the most compact design and allowed symmetrical shape from the crankshaft W to the right and left.
Um ein zentrales Durchbohren der Zylinder zu erreichen, sind die Saugventile S an die Stirnflächen der Pumpenkörper C gelegt, was den Vorteil der Verringerung des schädlichen Raumes gewährte. Unmittelbar über den Saugventilen 5 angeordnet befinden sich die Druckventile D. In order to achieve a central piercing of the cylinder, the suction valves S are placed on the end faces of the pump body C, which has the advantage of reducing the harmful space. The pressure valves D are located directly above the suction valves 5.
Der mittlere Teil der Pumpe — die beiden Kopfstücke der Zylinderkörper C — ist als geschlossenes Gehäuse ausgebildet, das in seiner Größe gerade genügt, um der Verschiebung der Kurbelschleife K Platz zu gewähren.The middle part of the pump - the two head pieces of the cylinder body C - is designed as a closed housing, which is just enough in size to allow the displacement of the crank loop K space.
Die beiden Hälften der Pumpengehäuse respektive Zylinder C sind — um die genaue Zentrierung gegenseitig zu gewährleisten — derart, ausgeführt, daß die Augen für die Verbindungsschrauben A etwas übergreifen.The two halves of the pump housing or cylinder C are designed in such a way that the eyes for the connecting screws A overlap somewhat in order to ensure that they are mutually centered exactly.
Da diese Schrauben gegen die wechselnden Druckbeanspruchungen jedoch nicht genügen würden, sind — um eine weitere Sicherung herbeizuführen — die aufschraubbaren Kugellagerdeckel E derart ausgebildet, daß dieselben außer dem genauen Einstellen und Halten der äußeren Kugellagerringe gleichzeitig die beiden Pumpenhälften C verbinden. Dadurch wird neben einem staub- und öldichten Verschluß der Kurbelkammer eine Entlastung der Verbindungsschrauben gegen Zugspannungen und eine feste Verbindung der Pumpenhälften geschaffen.Since these screws would not be sufficient against the changing pressure loads, the screw-on ball bearing caps E are designed in such a way that they connect the two pump halves C at the same time as well as precisely setting and holding the outer ball bearing rings. As a result, in addition to a dust-tight and oil-tight seal of the crank chamber, the connection screws are relieved of tensile stress and the pump halves are firmly connected.
Zur Erreichung dieser Zwecke dient die neuartige Lagerung der Kurbelwelle W, die hier nicht wie allgemein dicht neben den Kurbelarm sondern auf den als Scheiben ausgebildeten Kurbelarmen stattfindet, deren äußerer Rand gehärtet gleichzeitig als Lauffläche für das Kugellager dient.To achieve these purposes, the novel mounting of the crankshaft W is used, which here does not take place close to the crank arm, as is generally the case, but on the crank arms designed as disks, the hardened outer edge of which also serves as a running surface for the ball bearing.
Durch diese Art wird erreicht: eine schmale Bauart bei Lagerung der Kurbelwelle W in unmittelbarer Nähe der wirksamen Kräfte.This type achieves: a narrow design with the crankshaft W bearing in the immediate vicinity of the effective forces.
Die Schmierung der beweglichen Teile der Pumpe ist eine selbsttätige und dauernde, da die Köpfe der beiden Pumpenhälften C als ein allseitig geschlossenes öldichtes Gehäuse ausgebildet sind. - Die Füllung und Entleerung erfolgt durch die mit Schrauben verschlossenen Schmierlöcher.The lubrication of the moving parts of the pump is automatic and permanent, since the heads of the two pump halves C are designed as an oil-tight housing that is closed on all sides. - The filling and emptying takes place through the lubrication holes closed with screws.
