Description

KAISERLICHESIMPERIAL

PATENTAMTPATENT OFFICE

KLASSE S9: Pumpen.CLASS S9: Pumps.

Die Erfindung besteht in der Anordnung zweier seitlich gelagerten rotirenden Trommeln im Pumpengehäuse, deren Peripherie die Abdichtung zwischen Saug- und Druckstutzen bildet, und in der Herstellung einer gleichmäfsigen stofsfreien Bewegung der Flüssigkeit in den Saug- und Druckröhren.The invention consists in the arrangement of two laterally mounted rotating drums in the pump housing, the periphery of which is the seal between the suction and discharge ports forms, and in the production of a uniform, substance-free movement of the liquid in the suction and pressure pipes.

In dem Gehäuse α α rotiren die beiden Trommeln b b, welche auf den Wellen c c und den Zapfen dd befestigt sind.In the housing α α rotate the two drums bb, which are attached to the shafts cc and the pin dd.

Dieselben nehmen die Schieberkolben e e auf.The same take on the spool ee .

Die Trommeln b b sind seitlich gelagert und gestattet die Form des Gehäuses α α den Schieberkolben e e in jeder Stellung eine constante Länge.The drums bb are mounted laterally and the shape of the housing α allows the slide piston ee a constant length in every position.

Jeder der beiden Stutzen ff kann, der Drehungsrichtung der Trommeln b b angepafst, sowohl als Saug- oder Druckrohranschlufs verwendet werden.Each of the two nozzles ff can, adapted to the direction of rotation of the drums bb , be used both as suction or pressure pipe connections.

Die Trommeln b b berühren sich mit ihrer Peripherie continuirlich bei k und bilden dadurch eine Abdichtung zwischen Saug- und Druckrohr.The drums bb touch with their periphery continuously at k and thereby form a seal between the suction and pressure pipes.

Bei gleicher Umfangsgeschwindigkeit der beiden Trommeln b b haben die Enden der Schieberkolben e e fortwährend veränderliche Geschwindigkeit. Vom Punkt k an wird die Bewegung der saugenden und gleichzeitig drückenden Kolbenenden über g oder i nach h immer beschleunigter, von da an über g oder i nach k langsamer. Es entsteht hierdurch eine ungleichmäfsige stofsweise Bewegung der Flüssigkeit in den Röhren.With the same circumferential speed of the two drums bb , the ends of the slide pistons ee have a continuously variable speed. From point k on, the movement of the sucking and simultaneously pressing piston ends becomes increasingly accelerated via g or i to h , from then on it becomes slower via g or i to k. This creates an uneven material movement of the liquid in the tubes.

Durch Anwendung der beiden Ellipsenräder Z / und des dazu passenden Antriebsrades m erhalten die Trommeln b b eine derartige beschleunigte und langsamer werdende Bewegung, dafs die Schieberkolben e e mit ihren Enden an den Wandungen des Gehäuses α α eine gleichmäfsige Umfangsgeschwindigkeit erhalten, und ist dadurch eine gleichmäfsige stofsfreie Bewegung der Flüssigkeit in den Saug- und Druckröhren hergestellt.By using the two elliptical gears Z / and the corresponding drive wheel m, the drums bb receive such an accelerated and slowing motion that the slide pistons ee with their ends on the walls of the housing α α receive a uniform circumferential speed, and are thus uniform material-free Movement of the liquid established in the suction and pressure tubes.
