Description

Drehkolbenverdichter mit sichelförmigem Arbeitsraum und radial verschiebbaren Kolben Das Hauptpatent betrifft einen Verdichter mit sichelförmigem Arbeitsraum und radial verschiebbaren Kolben, bei welchem die Abdichtung des Zylinderraumes an beiden Stirnseiten durch elastisch angepreßte Deckel, scheiben erfolgt, die durch auf der Kolbentrommelwelle angeordnete und durch Federn belastete Druckscheiben in Drehung versetzt werden, und von denen jede :einen in Endaussparungen des Zylinders gelagerten, zur Aufnahme der Fliehkräfte der Kolben nienendeai Stützring trägt. Gemäß der Erfindung soll nun diese Bauart =in einer vornehmlich für kleinere Verdichter geeigneten Weise vereinfacht werden, indem nämlich die Abdichtung des Zylinders nur an einer Seite durch eine elastisch angepreßte und umlaufende Deckelscheibe erfolgt, welche den einzigen axial verschiebbar gelagerten Stützring des Zylinders antreibt, während auf der anderen Zylinderseite eine starr mit der Kolbentrommel verbundene Deckelscheibe gegen die Zylinderstirnwand unmittelbar abdichtet. Im Gegensatz- zu den bekannten Einrichtungen wird also hier nur ein einziger Stützring benutzt, der in gleicher Weise wie beim Hauptpatent durch Federn gegen sein Spurlager dichtend angepreßt wird und gemäß der Erfindung so bemessen werden soll, daß seine Breite mindestens der halben Zylinderlänge entspricht. Ein solcher Stützring ist insbesondere bei kleineren Maschinen in der Lage, die Fliehkräfte der Kolben in der gleichen Weise aufzunehmen, wie dies sonst durch die beiden in den Endaussparungen des Zylinders angeordneten Stützringe geschieht. Ebenso genügt auch die elastische Lagerung von Stützring und Deckelscheibe auf der einen Zylinderseite, um alle durch Temperaturschwankungen hervorgerufenen Längenänderungen auszugleichen.Rotary piston compressor with sickle-shaped working space and radially movable Piston The main patent relates to a compressor with a sickle-shaped working space and radially displaceable piston, in which the sealing of the cylinder space at both ends by elastically pressed covers, slices takes place, which through Pressure disks arranged on the piston drum shaft and loaded by springs rotated, and each of which: one in end recesses of the cylinder bearing, to absorb the centrifugal forces of the piston nienendeai support ring carries. According to the invention, this design should now be used primarily for smaller compressors suitably simplified, namely by sealing the cylinder only on one side by an elastically pressed and encircling cover disc takes place, which is the only axially displaceable support ring of the cylinder drives, while on the other side of the cylinder one is rigid with the piston drum connected cover plate seals directly against the cylinder end wall. In contrast- In addition to the known devices, only a single support ring is used here, which in the same way as in the main patent sealing against its thrust bearing by springs is pressed and is to be dimensioned according to the invention so that its width corresponds to at least half the cylinder length. Such a support ring is in particular with smaller machines able to keep the centrifugal forces of the pistons in the same Way, as otherwise, through the two in the end recesses of the cylinder arranged support rings happens. The elastic mounting of is also sufficient Support ring and cover plate on one side of the cylinder, to avoid all of them due to temperature fluctuations to compensate for any changes in length.

In der Zeichnung ist der Verdichter nach der Erfindung dargestellt.In the drawing, the compressor according to the invention is shown.

Auf der Welle i ist die Kolbentrommel 2 fest angeordnet, in deren Schlitzen die Schieberkolben 3 gleiten und sich gegen die Wandung des Zylinders q. anlegen. Die Abdichtung des Zylinders erfolgt an der einen Stirnseite durch -eine zentrisch zum Zylinderraum angeordnete Deckelscheibe 5, welche durch eine Druckscheibe 6 vermittels der Glockenfeder 7 gegen die Stirnwand 9 der Kolbentrommel 2 elastisch angepreßt wird. Die Druckscheibe 6 sitzt auf einer besonderen Trägerscheibe 6', derart, daß sich die Glokkenfeder gegen den Rand 6" der Träger- Scheibe abstützt. Die Einstellung der Federspannung geschieht mittels der Stellmutter 8, wobei deren Bewegung durch den Rand i' der Welle i begrenzt wird. Mit der Deckelscheibe 5 ist der Stützring i i derart durch einen Mitnehmer a q. verbunden, daß der Ring eine axiale Verschiebung ausführen kann, wobei die dichtende Anlage gegen sein Spurlager durch Federn 25 erreicht wird. Die Abdichtung der Deckelscheibe gegen den Stützring geschieht mittels des Dichtungsringes 26 und des Kolbenringes a7. Der Stützring muß in seiner Breite mindestens der halben Zylinderlänge entsprechen und ist in der dargestellten Ausführungsfo in sogar noch etwas länger gewählt.On the shaft i, the piston drum 2 is fixedly arranged, in whose slots the slide piston 3 slide and against the wall of the cylinder q. invest. The cylinder is sealed at one end by a cover disk 5 which is arranged centrally to the cylinder space and which is elastically pressed against the end wall 9 of the piston drum 2 by a pressure disk 6 by means of the bell spring 7. The thrust washer 6 sits on a special support disk 6 'so that the bell spring is supported against the edge 6 "of the support disk. The spring tension is set by means of the adjusting nut 8, the movement of which is limited by the edge i' of the shaft i The support ring ii is connected to the cover disk 5 by a driver a q. in such a way that the ring can move axially, the sealing contact against its thrust bearing being achieved by springs 25. The cover disk is sealed against the support ring by means of of the sealing ring 26 and the piston ring 7. The width of the support ring must correspond to at least half the length of the cylinder and in the embodiment shown is selected to be even somewhat longer.

Auf der linken Zylindeirseite erfolgt die Abdichtung durch eine vermittels Schrauben mit der Kolbentrommel starr verbundene Deckelscheibe 5', die unmittelbar gegen die Zylinderwand dichtet.On the left side of the cylinder, the seal is made by means of a Screws rigidly connected to the piston drum cover plate 5 ', which directly seals against the cylinder wall.

Auftretende Längenunterschiede der Maschinenteile werden in ähnlicher Weise wie beim Hauptpatent durch die .elastische Lagerung des Scheibensystems und des Stützringes im Zusammenwirken mit der entsprechend ausgestalteten Lagerung der Achsstümpfe ausgeglichen.Any differences in length of the machine parts are more similar As with the main patent, thanks to the elastic mounting of the disc system and of the support ring in cooperation with the correspondingly designed storage of the Axle stumps balanced.
