KAISERLICHESIMPERIAL PATENTAMTPATENT OFFICE PATENTSCHRIFTPATENT LETTERING KLASSE S9: Pumpen.CLASS S9: Pumps. Patentirt im Deutschen Reiche vom 17. October 1890 ab.Patented in the German Empire on October 17th, 1890. In die Pumpe ist aufser dem Arbeitskolben a ein zweiter Kolben b von demselben Durchmesser eingesetzt. Letzterer kann vermittelst der Muttern c und der Feder d derartig eingestellt werden, dafs α bei seinem Auf- und Niedergang b entweder gar nicht oder fortwährend berührt.In addition to the working piston a, a second piston b of the same diameter is inserted into the pump. The latter can be adjusted by means of the nuts c and the spring d in such a way that α either does not touch b at all or continuously during its ascent and descent. Im ersten Falle fördert die Pumpe so viel, wie durch Hub und Durchmesser des Kolbens bedingt ist, im zweiten Falle fördert sie gar nichts.In the first case, the pump delivers as much as the stroke and diameter of the piston is conditional, in the second case it does not support anything. Innerhalb dieser Grenzen kann man jede beliebige Fördermenge erreichen. Bemerkenswerth ist, dafs der Beginn der Druckperiode dabei unverändert bleibt.Any delivery rate can be achieved within these limits. Noteworthy is that the beginning of the printing period remains unchanged. Paentt-Anspruch:Patent claim: Eine Kolbenpumpe von regelbarer Leistungsfähigkeit, welche letztere dadurch erreicht ist, dafs Jder Arbeitskolben (a) auf einem mehr oder weniger grofsen Theil seines Hubes einen im Pumpengehäuse gegen den Druck von Federn, Gewichten oder dergleichen verschiebbaren Kolben (b) beeinflufst.A piston pump of variable capacity, the latter is achieved, that J the working piston (a) on a more or less great part of its stroke a in the pump housing against the pressure of springs, weights or the like displaceable piston (b) beeinflufst.
