Zusatz zum Patente ΛΪ 100487 vom 9. September 1896.Addendum to patent ΛΪ 100487 from September 9, 1896.
Patentirt im Deutschen Reiche vom 15. August 1897 ab. Längste Dauer: 8. September 1911.Patented in the German Empire on August 15, 1897. Longest duration: September 8, 1911.
Die vorliegende Erfindung betrifft eine wesentliche Verbesserung an Rotationspumpen der unter Nr. 100487 patentirten Art.The present invention relates to a substantial improvement in rotary pumps of Art.
Die Neuerung bezieht sich besonders auf die Ausführung der Flügelkolben und ist dazu bestimmt, die Leistungsfähigkeit bezw. technische Wirkung erwähnter Pumpen um ein Bedeutendes zu vergröfsern, welcher Effect eine Folge der durch die neue Kolbenbauart erreichten innigen Abdichtung und der grofsen Haltbarkeit der Kolben ist.The innovation relates in particular to the design of the wing pistons and is part of it determined, the performance respectively. technical effect of the pumps mentioned by one Significantly to enlarge what effect a consequence of the new piston design achieved intimate sealing and the great durability of the pistons.
Die beiliegende Zeichnung veranschaulicht die Neuerung durch sechs Figuren, von denen zeigt:The accompanying drawing illustrates the innovation through six figures, of which shows:
Fig. ι eine Stirnansicht eines Flügelkolbens in theilweisem Schnitt,Fig. Ι a front view of a winged piston in partial section,
Fig. 2 einen Längsschnitt durch den Flügelkolben, 2 shows a longitudinal section through the wing piston,
Fig. 3 eine Ansicht der dem Kolben zugekehrten Fläche einer an beiden Enden desselben anzuordnenden Metallscheibe, : Fig. 3 is a view of the side facing the piston surface of an at both ends thereof to be disposed metal disc:
Fig. 4, 5 und 6 veranschaulichen Einzeltheile. ·Figures 4, 5 and 6 illustrate individual parts. ·
Der neue Flügelkolben ist folgendermafsen eingerichtet:The new wing piston is set up as follows:
Die einzelnen Flügel bestehen aus abwechselnd an einander geschichteten Metallplatten b und weichen Leder-, Filz-, Gummioder dergl. Dichtungsplatten α, welche durch zwei nach dem Querschnitt des Kolbens hergerichtete Metallscheiben d und mehrere in Längsrichtung der Kolbenachse durch die Metallplatten b und Dich'tung'splatten α hindurchgehende Schrauben s zusammengeprefst werden.The individual wings consist of alternately stacked metal plates b and soft leather, felt, rubber or the like. Sealing plates α, which are formed by two metal disks d and several in the longitudinal direction of the piston axis through the metal plates b and sealing 'plates α through screws s are pressed together.
Wie aus den Fig. 4 und 5 hervorgeht, sind die gegen die Cylinderwandung gerichteten Kanten der Metallplatten b Zickzack- oder wellenförmig zugeschärft oder messerscharf abgereift. Die hierdurch entstandenen Einkerbungen werden beim Zusammenziehen von den aus Fig. 1 im Querschnitt und Fig. 6 in Vorderansicht dargestellten weichen Dichtungsplatten α vollständig ausgefüllt, so dafs gegen die Cylinderwandung hin eine vollkommen geschlossene Dichiungsoberfläche entsteht.As shown in FIGS. 4 and 5 is apparent that directed against the edges of the metal plates Cylinderwandung b zigzag or wave-shaped sharpened or knife-sharp abgereift are. The resulting notches are completely filled when the soft sealing plates α shown in cross section in FIG. 1 and in front view of FIG. 6 are drawn together, so that a completely closed sealing surface is created against the cylinder wall.
Die Befestigung der Metallplatten b am Kolben bezw. an der Kolbenhülse c kann auf beliebige Weise geschehen.The attachment of the metal plates b on the piston BEZW. on the piston sleeve c can be done in any way.
Bei der auf der Zeichnung dargestellten Ausführungsform haben die Metallplatten b Ansätze erhalten und sind mittels derselben in Längsnuthen der Kolbenhülse c eingeschoben. Die mittelste der Platten b, welche zu beiden Seiten Ansätze erhalten hat, ist durch zwei aus Fig. ι ersichtliche Schrauben, die bis in die Welle n> eingreifen, gegen seitliche Verschiebung gesichert, so dafs dadurch auch die Flügel in ihrer Stellung zur Welle w fixirt werden. Die Endplatten d haben AussparungenIn the embodiment shown in the drawing, the metal plates b have received approaches and are inserted into the longitudinal grooves of the piston sleeve c by means of the same. The middle one of the plates b, which has received on both sides of approaches, is defined by two of FIG. Ι apparent screws> engaged to the shaft n, secured against lateral displacement, so characterized DAF the wings in their position relative to the shaft w be fixed. The end plates d have recesses
