Description
Rotationskolben-Verbrennungsmotor Die Erfindung betrifft einen Rotationskolben-Verbrennungsmotor, der sich durch günstige Gestaltungsmöglichkeit des Arbeitsdiagrammes und geringen Brennstoffverbrauch auszeichnet. Rotary piston internal combustion engine The invention relates to a rotary piston internal combustion engine, which is characterized by favorable design options for the work diagram and low Fuel consumption.
Bei den bekannten Rotationskolben-Verbrennungsmotoren liegt die Gestalt des Brennvauses weitestgehend fest.In the known rotary piston internal combustion engines, the shape lies of the Brennvaus as far as possible.
Aufgabe der vorliegenden Erfindung ist es, durch eine freiere Gestaltung des Arbeitsrauues das Arbeitsdiagramm zu beeinflussen und einen besonders guten Wirkungsgrad des Motors zu erzielen. Nach der Erfindung wird diese Aufgabe durch einen scheibenförmigen Innenraum von etwa elliptischem Querschnitt gelöst, an dessen kleinstem Durcbaesser ein Rotor mit radial beweglichen Trennwänden dichtend anliegt und der von der üblichen Syimiietrieform wie folgt abweicht: Die Mittelpunkte der beiden großen Kriti-ungsradien der Ellipse sind um einige Prozente des größten Ellipsendurchmessers von der EinlaB- und Auslaßöffnung wegversetzt, und die Mittelpunkte der kleineren Krümmungsradien der Ellipse sind nach der Einlaß- und Auslaßöffnung hin um einige Prozent des größten Ellipsendurchmessers herangerückt. Die Zeichnung gibt einen RotationskQlben-Verbrennungsmotor nach der Erfindung vorwiegend skizzenhaft wieder, und zwar ist: Fig. 1 ein Schnitt nach der Linie I-I der Fig. 2 und Fig. 2 ein Draufblick auf einen Rotationskolben-Verbrennungsitiotor nach der Erfindung.The object of the present invention is to provide a freer design of the work roughness to influence the work diagram and a particularly good one To achieve the efficiency of the engine. According to the invention this object is achieved solved a disc-shaped interior space of approximately elliptical cross-section, at which smallest diameter a rotor with radially movable partitions rests in a sealing manner and which deviates from the usual symmetry as follows: The midpoints of the Both of the large critical radii of the ellipse are a few percent of the largest ellipse diameter offset from the inlet and outlet ports, and the centers of the smaller ones Radii of curvature of the ellipse are after the inlet and Outlet opening moved closer by a few percent of the largest ellipse diameter. The drawing gives a rotary cylinder internal combustion engine according to the invention predominantly in sketch form again, namely: Fig. 1 is a section along the line I-I of Fig. 2 and Fig. Figure 2 is a plan view of a rotary piston internal combustion engine according to the invention.
Zwischen zwei Außenteilen 1 und 2 ist mittels Schrauben 3-6 ein Mittelteil 7 eingespannt, in dessen Aussparung 8 von annähernd elliptischem Querschnitt ein Rotor 9 so gelagert ist, daß er an gegenüberliegenden Berührungslinien 10, 11 der Innenwand der Aussparung 8 dauernd anliegt.Between two outer parts 1 and 2 there is a middle part by means of screws 3-6 7 clamped, in the recess 8 of an approximately elliptical cross-section Rotor 9 is mounted so that it is on opposite lines of contact 10, 11 of the Inner wall of the recess 8 rests continuously.
Vor und hinter einer dieser Berührungslinien sind eine Einlaßdffnung l und eine Auslaßöffnung 13 vorgesehen.In front of and behind one of these lines of contact there is an inlet opening l and an outlet port 13 is provided.
Eine Öffnung 24 etwa an der gegenüberliegenden Stelle dient zur Aufnahme einer Zündvorrichtung oder einer Einspritzdilse.An opening 24 approximately at the opposite point is used for receiving an igniter or an injector.
Der Rotor 9 weist Ausnehmungen 14 für die Aufnahme je eines Schiebers 15 auf, der von einer Feder 16 nach außen bis zur Anlage an die Innenwand der Aussparung 8 gedrückt wird. Im Gegensatz zu den bekannten Vorschlägen hat nun der durch die Aussparung 8 bestimmte Arbeitsraum im Querschnitt nicht die Form einer Ellipse, sonein eher die einer Erdbeere, ist also oben deutlich breiter als unten. Gemäß der Erfindung sind deswegen die Mittelpunkte 17 und 18 der großen Krümmungsradien 19 und 20 einer normalen Ellipse etwa um 4 % des größten Durchmessers 21 (Fig. 2) von der Einlaßöffnung 12 bzw. der Auslaßöffnung 13 zurückverlegt, während der Mittelpunkt 22 der kleinen rtiinuiungsradien 23 um 4 % des größten Durchmessers 21 der üblichen Ellipse nach der Einlaßöffnung 12 bzw. der Auslaßöffnung 13 hin herangerückt ist.The rotor 9 has recesses 14 for receiving one slide each 15 on, which by a spring 16 to the outside to rest on the inner wall of the recess 8 is pressed. In contrast to the known proposals, the Recess 8 certain work space in cross section not the shape of an ellipse, It's more like a strawberry, so it is significantly wider at the top than at the bottom. According to of the invention are therefore the centers 17 and 18 of the large radii of curvature 19th and 20 of a normal ellipse around 4% of the largest diameter 21 (FIG. 2) of the inlet opening 12 and the outlet opening 13 moved back, while the center 22 of the small rtiinuiungsradien 23 by 4% of the largest diameter 21 of the usual Ellipse is moved towards the inlet opening 12 and the outlet opening 13.
