Description

Drehkolbenmaschine (Verdichter oder Pumpe) mit sichelförmigem Arbeitsraum und in der Kolbentrommel verschiebbaren Flachkolben Es ist bekannt, daß bei Drehkolbenmaschinen mit sichelförmigem Arbeitsraum und in der Kolbentrommel verschiebbaren Flachkolben die letzteren in seitlichen Führungsnuten, die unmittelbar in den Lagerdeckeln oder in besonderen Stützringen oder Scheiben angebracht sind, geführt werden. Die Führung 'der Flachkolben in den Nuten hat den Zweck, die beim Umlauf auftretenden Fliehkräfte abzufangen. Man hat versucht, die durch Fliehkräfte erzeugte große Reibung in den Nuten dadurch zu beheben, daß man die Seitenscheiben oder Stützringe mit umlaufen ließ. Die Anordnung von Seitenscheiben oder Stützringen wurde bisher nur bei solchen Drehkolbenmaschinen ausgeführt, bei denen die Flachkolben sich in der Kolbentrommel radial bewegen, exzentrisch zur Gehäusebohrung. Dies hat den Nachteil, daß die Flachkolben nur mit einer Linie an der Gehäusewandung abdichteten. Es traten daher große Spaltverluste ein, die den Wirkungsgrad sehr verminderten.Rotary piston machine (compressor or pump) with sickle-shaped working space and flat piston displaceable in the piston drum It is known that in rotary piston machines with sickle-shaped working space and flat pistons that can be moved in the piston barrel the latter in lateral guide grooves that are directly in the bearing caps or are attached in special support rings or discs. The leadership The purpose of the flat piston in the grooves is to reduce the centrifugal forces that occur during rotation intercept. Attempts have been made to reduce the large friction generated by centrifugal forces in the Correct grooves by rotating the side windows or support rings let. The arrangement of side windows or support rings has so far only been used in such Rotary piston machines run in which the flat pistons are in the piston drum move radially, eccentrically to the housing bore. This has the disadvantage that the flat pistons seal only with a line on the housing wall. Large gap losses therefore occurred one, which greatly reduced the efficiency.

Die vorliegende Erfindung behebt diesen Mangel dadurch, daß die Flachkolben zentrisch zur Gehäusebohrung geführt und zu diesem Zweck in der Kolbentrommel sich in der bekannten Drehwalze, der sogenannten Nuß, verschieben.The present invention overcomes this deficiency in that the flat bottom flasks guided centrally to the housing bore and for this purpose in the piston drum move in the well-known rotating roller, the so-called nut.

Wichtig ist auch, daß die seitlichen Führungsscheiben in an sich bekannter Weise unmittelbar an den Kolben anliegen und im Zentrum gelagert sind, also normale Lagerung verwendet werden kann.It is also important that the lateral guide washers are known per se Way directly to the piston and are stored in the center, so normal Storage can be used.

Die Zeichnung veranschaulicht ein Ausführungsbeispiel der Erfindung.The drawing illustrates an embodiment of the invention.

Abb. i zeigt die Maschine im Längsschnitt A-A der Abb. z, Abb. z im Querschnitt B-B der Abb. i, Abb. 3 im Querschnitt C-C der Abb. i. In dem Gehäuse a dreht sich die exzentrisch zu ihm liegende Kolbentrommel b, die unmittelbar mit der Antriebswelle e, die in den Lagern d, dl gelagert ist, verbunden ist. Zu beiden Stirnseiten b1, b= der Kolbentrommel b sind die Führungs- und Dichtungsscheiben e, e1, die in den Kugel- oder Rollenlagern f, f 1 unabhängig von der Kolbentrommel b gelagert werden, angebracht. Die Scheiben e, e1 besitzen zur zwangsläufigen Führung der Förderkolben g die Nuten h, 1t1. In diese Führungsnuten h, hl greifen die mit den Förderkolben ä verbundenen Gleitstücke i ein. Die Führungsnuten h, hl sind zentrisch zur Gehäusebohrung a1.Fig. I shows the machine in longitudinal section AA of Fig. Z, Fig. Z in cross section BB of Fig. I, Fig. 3 in cross section CC of Fig. I. In the housing a, the eccentric piston drum b rotates, which is directly connected to the drive shaft e, which is mounted in the bearings d, dl. The guide and sealing disks e, e1, which are mounted in the ball or roller bearings f, f 1 independently of the piston drum b, are attached to both end faces b1, b = of the piston drum b. The disks e, e1 have the grooves h, 1t1 for the positive guidance of the delivery pistons g. The sliding pieces i connected to the delivery pistons ä engage in these guide grooves h, hl. The guide grooves h, hl are centric to the housing bore a1.

Damit der Förderkolben ä zentrisch zur Gehäusebohrung a1 entsprechend den Führungsnuten h, hl umlaufen kann, verschiebt er sich in der Kolbentrommel b unter Vermittlung der Drehwalze L (Nuß)., Die Scheiben e, ei werden durch die Reibung der Kolbengleitstücke i in den Nuten h, Al gezwungen, an der Umlaufbewegung teilzunehmen. Die Maschine kann nach jeder beliebigen Drehrichtung durch Wechsel des Saug- oder Druckkanals h, hl laufen.Thus, the feed piston ä centrally to the housing bore a1 corresponding to the guide grooves h, can circulate hl, it slides in the piston drum b through the intermediary of the rotary roller L (nut)., The discs e, ei are the friction of the Kolbengleitstücke i in the grooves h , Al forced to participate in the orbital movement. The machine can run in any direction of rotation by changing the suction or pressure channel h, hl.
