Abstract

A rotary piston engine is proposed, which has a rotor (6) arranged in a housing (1). In the rotor (6) blades (13, 14, 15) are supported, the blade tips (37, 38, 39) of which run along an inner wall (3) of the housing (1) and thereby separate a plurality of working chambers in the housing (1) from one another. The blades (13, 14, 15) are designed as two-armed levers and their end (34, 35, 36) lying opposite the blade tip (37, 38, 39) is pivoted on a connecting rod (22, 23, 24). Each connecting rod (22, 23, 24) is seated on a pin (21), which is arranged eccentrically on the rotor (6). When the rotor (6) rotates, the blade tips (37, 38, 39) describe a curve deviating from a circular orbit and the form of a housing shell inner wall (3) is matched to this curve. The rotary piston engine can be used both as compressor and as supercharger or the like. <IMAGE>

Parallel- und innenachsige Umlaufkolbenmaschine Stand der TechnikState-of-the-art parallel and internal-axis rotary piston machine

Die Erfindung geht aus von einer parallel- und innenachsigen Umlaufkolbenmaschine nach der Gattung des Hauptanspruchs.The invention is based on a parallel and inner-axis rotary piston machine of the type Main claim.

Eine derartige Umlaufkolbenmaschine ist bekannt (DE-PS 2 626. IA9).. Bei dieser bekannten Bauart liegt, die Achse des Rotors achsparallel zur Achse des Gehäuses und je ein Bewegungspleuel für jeden Flügel ist auf einer Welle gelagert, deren Achse mit der des Gehäuses identisch ist. Durch die Exzentrizität der Pleuellagerung zur Rotorachse entsteht am freien Pleuelende eine Bewegung, die über einen besonderen Hebel auf den Flügel übertragen wird. Auf diese Weise beschreibt jede Flügelspitze entlang der Gehäusemantel-Innenwand eine Kreislinie, so daß bei Verwendung einer kreisförmigen Gehäusemantel-Innen-■wand eine gute Abdichtung der von den Flügeln getrennten Arbeitsräume erzielbar ist.Such a rotary piston machine is known (DE-PS 2 626. IA9) .. In this known design, the axis of the rotor axially parallel to the axis of the housing and one movement connecting rod for each wing is on a shaft stored whose axis is identical to that of the housing. Due to the eccentricity of the connecting rod bearing to the rotor axis A movement is created at the free end of the connecting rod, which is transferred to the wing via a special lever will. In this way, each wing tip describes a circular line along the inner wall of the housing jacket, so that when using a circular inner wall of the housing a good seal of the working spaces separated from the wings can be achieved.

Jedoch hat die bekannte Bauart den Nachteil, daß die Pleuel und die Hebel seitlich vom Rotor angeordnet wer-However, the known design has the disadvantage that the connecting rods and the levers are arranged to the side of the rotor.

den müssen. Dadurch ist die bekannte Bauart verhältnismäs sig sperrig. Dazu kommt die einseitige Beanspruchung der Rotorlagerung. Schließlich sind die bewegten Massen verhältnismäßig groß.the must. As a result, the known design is relatively bulky. In addition, there is the one-sided use of the Rotor bearing. After all, the moving masses are relatively large.

Vorteile der ErfindungAdvantages of the invention

Die parallel- und innenachsige Umlaufkolbenmaschine mit den kennzeichnenden Merkmalen des Hauptanspruchs hat demgegenüber den Vorteil, daß die Anlenkung und Führung der Flügel innerhalb des Rotors angeodnet sind, wodurch sich eine erhebliche Verkleinerung der Baulänge der Maschine ergibt·The parallel and inner-axis rotary piston machine with the characterizing features of the main claim has the advantage that the articulation and guidance of the The blades are located within the rotor, which significantly reduces the overall length of the machine results

Dazu kommt, daß am Rotor keine seitlichen Momente auftreten. In addition, there are no lateral moments on the rotor.

Desweiteren ist es "von Vorteil, daß die mit den Flügeln beweglichen Massen verringert sind, so daß höhere Drehzahlen möglich werden.It is also an advantage that those with the wings moving masses are reduced, so that higher speeds are possible.

WirkungsweiseMode of action

Beim Antrieb der Antriebswelle kl dreht sich der Rotor mit den beiden Rotor-Deckeln 32 und 33. Über die drei auf dem Bolzen 21 gelagerten Pleuel 22, 23 und 2k wird den Flügelspitzen 37, 38, 39 der Flügel 1^, 15 und 16 eine Bewegung erteilt, die von einer Kreisform abweicht. Drei von den Flügeln *ik, 15 und 16 begrenzte Arbeitsräume verändern beim Umlauf des Rotors 6 ihr Volumen, so daß eine Verdrängung von einem hydraulischen oder gasförmigen Mittel von dem Einlaßstutzen k zu dem Auslaßstutzen 5 hin erfolgt.When the drive shaft kl is driven, the rotor rotates with the two rotor covers 32 and 33. Via the three connecting rods 22, 23 and 2k mounted on the bolt 21, the wing tips 37, 38, 39 of the wings 1 ^, 15 and 16 become one Movement granted that deviates from a circular shape. Three of the wings * ik, 15 and 16 limited working spaces change their volume during the rotation of the rotor 6, so that a displacement of a hydraulic or gaseous medium from the inlet port to the outlet port k is carried out 5.

Es ist zu bemerken, daß die Masse der bewegten Teile sehr gering ist und daß mit der erfindungsgemäßen Bauart eine einfache Bewegungseinrichtung für die Flügel geschaffen ist. Wenn auch der Bewegungsmechanismus keine Kreisbahn der Flügelspitzen bewirkt, so ist die von der Kreisform abweichende Form der Gehäusemantel-Innenwand 3 doch mitIt should be noted that the mass of the moving parts is very small and that with the inventive design a simple movement device for the wing is created. Even if the movement mechanism is not a circular path causes the wing tips, the shape of the housing jacket inner wall 3, which deviates from the circular shape, is also included
