Description

Abdichtungsvorrichtung für den Kolben von Pumpen mit umlaufendem, in der Kolbentrommel diametral verschiebbarem, Dichtungsleisten tragendem Kolben. Gegenstand der Erfindung ist eine Abdichtungsvorrichtung für den Kolben von Pumpen mit umlaufendem Kolben, der in der Kolbentrommel diametral verschiehbar und mit Dichtungsleisten versehen ist. Das Neue besteht darin, daß der Kolben aus zwei quer zur Treibwelle keilförmig geschnittenen Teilen c besteht und zwischen den Keilteilen c und den Dichtungsleisten d Druckfedern angeordnet sind.Sealing device for the piston of pumps with rotating, in the piston drum diametrically displaceable piston carrying sealing strips. The invention relates to a sealing device for the piston of pumps with rotating piston, which is diametrically displaceable in the piston drum and with Sealing strips is provided. The new thing is that the piston consists of two transversely to the drive shaft wedge-shaped cut parts c and between the wedge parts c and the sealing strips d compression springs are arranged.

Auf der Zeichnung ist die Erfindung dargestellt, und zwar zeigt: Fig. z einen Querschnitt nach A-B von Fig. 2, Fig. 2 einen senkrechtenLängsschnitt durch die Mitte von Fig. r, Fig. 3 einen Längsschnitt durch den Kolben nach C-D von Fig. r.The invention is shown in the drawing, namely: Fig. z is a cross-section along A-B of Fig. 2, Fig. 2 is a vertical longitudinal section the middle of Fig. r, Fig. 3 shows a longitudinal section through the piston according to C-D of Fig. r.

In dem Gehäuse d ist die Kolbentrommel b exzentrisch angeordnet, welche von dem Kolben mit den Dichtungsleisten d durchquert wird. Die Kolbentrommel wird durch die Treibwelle b in Drehung versetzt. Ein- und Auslaß ist durch Pfeile bezeichnet.In the housing d, the piston drum b is arranged eccentrically, which is traversed by the piston with the sealing strips d. The piston barrel will rotated by the drive shaft b. Inlet and outlet are indicated by arrows.

Der Kolben ist aus Holz, Fiber oder ähnlichem Material hergestellt und die Dichtungsleisten d bestehen aus gleichartigem Material. Diese Dichtungsleisten werden beim Unilauf der Pumpe durch die Zentrifugalkraft gegen die Gehäusewandung gedrückt und erzielen dadurch den AbschluB. Der Kolben besteht aus Hälften, die wie Keil und. Gegenkeil aufeinanderliegen. Druckfedern drücken einerseits gegen die Dichtungsleisten, anderseits gegen jede Kolbenhälfte, so daß diese infolge der Keilwirkung gegen die Stirnwände des Gehäuses angedrückt werden.The piston is made of wood, fiber or similar material and the sealing strips d are made of the same material. These sealing strips are pushed against the housing wall by centrifugal force when the pump is running pressed and thereby achieve the conclusion. The piston consists of halves that like wedge and. Mating wedge lie on top of one another. Compression springs push against one side the sealing strips, on the other hand against each piston half, so that this as a result of Wedge effect are pressed against the end walls of the housing.
