"Umlaufkolbenmaschine""Rotary piston machine"

Die Erfindung betrifft eine Umlaufkolbenmaschine mit einem Kolben, bestehend aus einer Kolbennabe und radial beweglichen Kolbenschiebern, der zusammen mit Seitenteilen in einem Mantel drehbar angeordnet ist, wobei die Kolbenschieber in Schlitzen der Kolbennabe und der Seitenteile geführt sind.The invention relates to a rotary piston machine with a Piston, consisting of a piston hub and radially movable piston slide, which together with side parts in a jacket is rotatably arranged, wherein the piston slide are guided in slots of the piston hub and the side parts.

Bei Maschinen, die mit hohen Drücken und hohen Drehzahlen umlaufen, ist der Wirkungsgrad wesentlich von der Reibung zwischen den beweglichen Teilen abhängig. Insbesondere werden die Kolbenschieber durch die Fliehkraft nach außen gedrückt, so daß sie an dem Mantel mit hoher Geschwindigkeit gleiten, was einen erheblichen Leistungsverlust und erhöhte Abnutzungserscheinungen zur Folge hat.In machines that rotate at high pressures and high speeds, the efficiency depends largely on the friction between the moving parts. In particular, the piston valves are pushed outwards by centrifugal force, so that they slide on the jacket at high speed, resulting in a significant loss of power and increased Causes signs of wear and tear.

Die Erfindung bezweckt vor allem eine Beseitigung dieses Nachteiles und besteht im wesentlichen darin, daß die Kolbenschieber zwangsläufig hydrostatisch mittels Kolben geführt werden, The main purpose of the invention is to eliminate this disadvantage and essentially consists in the fact that the piston valves are inevitably guided hydrostatically by means of pistons,

welche in radialen oder nahezu radialen Zylinderbohrungen der Seitenteile des Kolbens angeordnet sind und abwechselnd radial von außen und radial von innen beaufschlagt werden.which are arranged in radial or almost radial cylinder bores of the side parts of the piston and alternately acted upon radially from the outside and radially from the inside.

In der Zeichnung ist ein Ausführungsbeispiel der Erfindung schematisch dargestellt. In dem feststehenden Gehäuse 10 ist mittels der Lager 11 und 12 die Welle 13 mit dem Umlaufkolben 14 gelagert, welcher aus der Kolbennabe 15* den Sei- ^ tenteilen 16 und 17 und den in radialen Schlitzen 18 bzw. 19 der Kolbennabe bzw. der Seitenteile gleitend geführten Kolbenschiebern 20 besteht. Die zwischen den Kolbenschiebern 20 gebildeten Arbeitskammern 21 werden von einem Mantel 22 umschlossen, der in dem Gehäuse 10 mittels eines Kardanringes 25 allseitig beweglich gelagert ist. Der Kardanring 23 ist hierbei mit dem Mantel 22 durch zwei Zapfen 24 und mit dem Gehäuse 10 durch zwei zu den Zapfen 24 um 90 versetzte Zapfen 25 gelenkig verbunden.In the drawing is an embodiment of the invention shown schematically. In the stationary housing 10 is the shaft 13 with the rotary piston by means of the bearings 11 and 12 14 stored, which from the piston hub 15 * the side ^ tenteilen 16 and 17 and the piston slides slidingly guided in radial slots 18 and 19 of the piston hub or the side parts 20 exists. The working chambers 21 formed between the piston slides 20 are enclosed by a jacket 22, which is mounted movably on all sides in the housing 10 by means of a cardan ring 25. The gimbal ring 23 is here with the jacket 22 by two pins 24 and with the housing 10 by two to the pins 24 offset by 90 Pin 25 articulated.

W In dem dargestellten Ausführungsbeispiel sei beispielsweise angenommen, daß die Kolbenschieber bei einer Umdrehung der Welle 13 entsprechend zwei einander gegenüberliegenden segment förmigen Arbeitsräumen jeweils eine zweimalige Hin- und Herbewegung ausführen, so daß sich bei jeder Umdrehung die zwischen den einzelnen Kolbenschiebern gebildeten Arbeitskammern zweimal vergrößern und wieder verkleinern. Doch kann auch eine einfache exzentrische Anordnung zwischen Kolben 14 und Mantel 22 vorgesehen sein, so daß nur eine einmalige Ver- W example, assume that the spool in each case run at a revolution of the shaft 13 corresponding to two opposed segment-shaped working chambers, a two-time reciprocating movement, so that for each revolution of the working chambers formed between the individual piston slides enlarge twice, and in the illustrated embodiment, zoom out again. However, a simple eccentric arrangement between piston 14 and jacket 22 can also be provided, so that only a one-time connection

Erfindungsgemäß sind nun die Kolbenschieber 20 in radialer Richtung hydrostatisch geführt. Zu diesem Zweck sind in den äußeren, mit der Welle 13 fest verbundenen und zusammen mit dem Umlaufkolben umlaufenden Abschlußwänden 26 und 27 radial angeordnete Zylinder 28 vorgesehen, in denen Kolben 29 einwärts und auswärts parallel zur Richtung des Kolbenschieberhubes gleiten können. In einen Schlitz 30 des Kolbens 29 Λ greift jeweils ein Steg 31 am zugeordneten Kolbenschieber 20 ein. Durch Bohrungen 32 und 33 ist das radial innere bzw. das radial äußere Ende des jeweiligen Zylinders 28 mit der Kolbensteuerung verbunden. Durch die z.B. feststehende Steuerwelle, welche in der Zeichnung nicht dargestellt ist, weil Steuerwellen in verschiedenen Ausführungen bereits bekannt sind, und welche in der Bohrung der Kolbenwelle 13 gelagert ist bzw. in diese eingreift, können die Bohrungen 32 und 33 während des Kolbenumlaufs abwechselnd mit der Hochdruckleitung oder mit der Niederdruckleitung der Maschine verbunden werden, so daß die Kolben 29 und mit ihnen die Kolbenschieber 20 in den Schlitzen 1-8, 19 radial bewegt werden, wie es die Stellung des Umlaufkolbens verlangt.According to the invention, the piston slides 20 are now guided hydrostatically in the radial direction. For this purpose, in the outer end walls 26 and 27 that are fixedly connected to the shaft 13 and encircling together with the rotary piston, radially arranged cylinders 28 are provided, in which the piston 29 can slide inward and outward parallel to the direction of the piston slide stroke. In a slot 30 of the piston 29 engages Λ respective web 31 to the associated spool 20 a. The radially inner and the radially outer end of the respective cylinder 28 are connected to the piston control through bores 32 and 33. For example, the fixed control shaft, which is not shown in the drawing because control shafts are already known in various designs, and which is mounted in the bore of the piston shaft 13 or engages in it, the bores 32 and 33 can alternate with during the piston rotation the high-pressure line or the low-pressure line of the machine, so that the pistons 29 and with them the piston slide 20 are moved radially in the slots 1-8, 19, as required by the position of the rotary piston.

Die Verbindung zwischen den Kolben 29 und den Kolbenschiebern kann statt durch Stege auch durch Bolzen hergestellt werden. Auch kann die Steuerung der Bohrungen 32 und 33 von außen her erfolgen.The connection between the piston 29 and the piston slide can also be established by bolts instead of webs. The control of the drilling can be carried out 32 and 33 from the outside.
