Description
Abdichtungsvorrichtung für Pumpen mit umlaufendem Gehäuse. Im Hauptpatent ist eine Abdichtungseinrichtung für Pumpen mit umlaufendem Gehäuse, feststehendem exzentrischen Widerlagerkörper und mehreren, auf seinem Umfang abdichtend laufenden, in radialen Schlitzen des Gehäuses verschiebbaren, nachgiebig miteinander verbundenen Kolben behandelt, bei welcher als Verbindungsorgan und als Andrückorgan für die Kolben geschlossen, federnde Ringe dienen, welche die Kolben von außen umfassen. Die vorliegende Erfindung besteht darin, daß die federnden Umspannungsringe zusammenhängen und in ihrer Gesamtheit eine Schraubenfeder bilden. Dadurch wird nicht nur ein besonders gleichmäßiges Andrücken der Kolben erreicht, sondern zugleich die Herstellung bedeutend verbilligt und vereinfacht, da das Winkeln einer Schraubenfeder viel einfacher ist als die Herstellung din.es in sich geschlossenen, an allen Stell. möglichst gleichmäßig federnden Ringes. Ein. Ausführungsbeispiel der Erfindung ist in der Zeichnung dargestellt.Sealing device for pumps with surrounding housing. In the main patent is a sealing device for pumps with a rotating housing, fixed eccentric abutment body and several running sealingly on its circumference, slidable in radial slots of the housing, resiliently connected to one another Treated piston, in which as a connecting member and as a pressing member for the Piston closed, resilient rings are used, which surround the piston from the outside. The present invention is that the resilient looping rings are contiguous and in their entirety form a helical spring. This not only makes one special uniform pressing of the piston is achieved, but at the same time the production is significant Cheaper and simplified as it is much easier to angle a coil spring as the production of it is self-contained, as evenly as possible at all points resilient ring. A. Embodiment of the invention is in shown in the drawing.
Aber. i zeigt einen durch die Achse der Maschine geführten Schnitt mit den ruhenden Teilen der Maschine in Ansicht.But. i shows a section through the axis of the machine with the stationary parts of the machine in view.
Abb. 2 ist ein Schnitt nach Linie A-B der Abb. i.Fig. 2 is a section along line A-B of Fig. I.
Die in der Längsrichtung durchbohrten und als Zuführungs- und Abführungsrohre verwendeten Zapfen a sind in dem Bock b befestigt. Diese beiden Zapfen tragen den exzentrischen zylindrischen Körper c und bestehen mit ihm zweckmäßig aus einem Stück. The pins a, which are drilled through in the longitudinal direction and used as supply and discharge pipes, are fastened in the bracket b. These two pins carry the eccentric cylindrical body c and are expediently made of one piece with it.
Um die Zapfen a drehbar ist das zweckmäßig als Riemenscheibe verwendete Gehäuse der Pumpe, das aus den, beiden, in geeigneter Weise gegen die Zapfen a abgedichteten Seitenscheihen $ und dem im wesentlichen hohlzylindrischen Mittelstück f besteht. Die Bohrungen der Zapfen gehen in radiale Kanäle oder Bohrungen k des Körpers c Über, die nachentgegengesetzten Seiten am Umfang des Körpers c ausmünden.Rotatable about the pin a is expediently used as a pulley Housing of the pump, which consists of the two, sealed in a suitable manner against the pin a Seitenscheihen $ and the essentially hollow cylindrical center piece f consists. The bores of the pins go into radial channels or bores k of the body c About, the opposite sides open out on the circumference of the body c.
Die Kolben h; die auf dem Körper c umlaufen, werden von der um sie gelegten Schraubenfeder m umspannt und federnd angedrückt.The pistons h; which circulate on the body c are taken from the ones around them laid helical spring m spans and resiliently pressed.
Die Wirkungsweise der Maschine ist dieselbe wie bei derjenigen, die im Ausführungsbeispiel des Hauptpatentes angegeben ist.The operation of the machine is the same as that of the is indicated in the embodiment of the main patent.
