Description
Vorrichtung zur stirnseitigen Abdichtung der Kolben von Drehkolbenverdichtern mit sichelförmigem Arbeitsraum und im Gehäuse geführtem Widerlagerschieber. Die Erfindung betrifft die stirnseitige Abdichtung der Kolben von Drehkolbenverdichtern mit sichelförmigem Arbeitsraum und im Gehäuse geführtem Widerlagerschieber Die Abdichtung erfolgt nach einem früheren Vorschlage (Patent 430393) des Erfinders durch radiale Leisten, die in den Stirnseiten des Kolbens liegen. Durch diese Leisten wird nicht nur das Gewicht des Kolbens, sondern auch die exzentrische Masse @ ergrößer t. Infolgedessen werden die Ausgleichgew ichte des Kolbens recht groß. Günstigere Verhältnisse lassen sich erzielen, wenn die Leisten in den Deckel des Zylinders gelegt werden. Eine derartige Anordnung ist Gegenstand der vorliegenden Erfindung.Device for sealing the end of the pistons of rotary lobe compressors with a sickle-shaped working space and an abutment slide guided in the housing. The invention relates to the end-face sealing of the pistons of rotary lobe compressors with a sickle-shaped working chamber and an abutment slide guided in the housing. These bars not only increase the weight of the piston, but also the eccentric mass @. As a result, the balancing weights of the piston become quite large. More favorable conditions can be achieved if the strips are placed in the cover of the cylinder. Such an arrangement is the subject of the present invention.
Abb. i zeigt den Deckel in Ansicht, Abb. 2 im Schnitt.Fig. I shows the cover in a view, Fig. 2 in section.
An dem Deckel sind :guten 25 eingeschnitten, in die zwei Leisten 26 eingepaßt sind. Die Leisten sind nach oben hin über den Durchmesser des Zylinders hinaus verlängert und treten in die seitliche Führung 27 des Widerlagerschiebers ein. Ihr inneres Ende liegt unmittelbar an dem Deckellager 28 des Kolbens. Die Leisten werden durch Federn 29 mit elastischem Druck an die Stirnfläche des Kolbens angedrückt.On the cover are: good 25 cut into which two strips 26 are fitted. The bars are extended upwards beyond the diameter of the cylinder and enter the lateral guide 27 of the abutment slide. Its inner end lies directly on the cover bearing 28 of the piston. The strips are pressed against the end face of the piston with elastic pressure by springs 29.
Diese Abdichtung hat den Vorteil, daß die Dichtungsleisten nicht mit dem Kolben umlaufen. Die Gegengewichte, die die im Kolben liegenden Dichtungsleisten erfordern, können in Wegfall kommen. Das ganze Gewicht des Kolbens wird dadurch wesentlich verringert.This seal has the advantage that the sealing strips do not have rotate around the piston. The counterweights that hold the sealing strips in the piston may be omitted. It takes all the weight of the piston off significantly reduced.
