Die Erfindung betrifft eine Wind- bzw« Wasserkraftmaschine mit aus
zwei beidseitig an einer vertikalen Weile einander zugeordneten Rotor E blättern, Wie Flügel oder Schaufeln* die durch die Fluidströmung ange
trieben werden.The invention relates to a wind or hydroelectric machine with
two rotors E arranged on either side of a vertical shaft, like wings or blades* which are moved by the fluid flow
be driven.

Bekannt sind Windrädkonstruktionen dieser Art, sogenannte Parianemonen .
Neben dem als Anemometer verwendeten Schalenkreuz ist der Savonius-Rotor zu erwähnen, der zwei gegenüber der vertikalen Drehachse versetzte | starr in einem Rotor montierte Halbzyiinderschalen aufweist.
Mit allen diesen Anordnungen gelingt es nicht, die Windkraft optimal
auszunutzen, weil ein großer Teil des von den im Wind mitlaufenden
Schaufeln aufgebrachten Drehmomentes von den dem Wind entgegenlaufen
den Schaufeln wieder aufgezehrt wird.Wind turbine constructions of this type, so-called parianemones, are well known.
In addition to the cup cross used as an anemometer, the Savonius rotor should be mentioned, which has two half-cylinder cups offset from the vertical axis of rotation and rigidly mounted in a rotor.
All these arrangements do not make it possible to optimally harness wind power
because a large part of the energy generated by the wind
Blades applied torque from the wind against the
the shovels are consumed again.

Dazu ist ein ganz erheblich großer Bauaufwand mit einer sehr i) großen Anzahl verschiedener Einzelteile nötig, was besonders bei den j·'In order to avoid this disadvantage, adjustment mechanisms have been used .

Die Aufgabe dieser Erfindung besteht demzufolge darin, eine Wind- bzw. fi Wasserkräftmaschine der eingangs genannten Art zu schaffen^ bei we 1 - |The object of this invention is therefore to create a wind or water power machine of the type mentioned at the beginning, in which we 1 - |

I eher ohne großen, verschleißbehafteten Aufwand eine günstige Ein- j stellung der dem Wind entgegenlaufenden Schaufeln auch bei großdimen- j sionierten Turbinen erreicht wird. |I rather a favorable adjustment of the blades running against the wind can be achieved without great effort and wear, even in large-dimensioned turbines. |

Diese Aufgabe wird durch eine Bauart gemäß den kennzeichnenden Merkma-* ien des Patentanspruches 1 gelbst.This object is achieved by a design according to the characterizing features of patent claim 1.

Ift völlig überraschender Weise stellen sich beim Erfindungsgegenstand die dem Fluid entgegen-iäuf enden Ro horb 1 Mt ter selbsttätig in ei'ne widefötändsarme (Null-) Stellung und gelangen ebenso wieder in Betriebsstellung. Die Stellkräfte Werden dabei durch die FIuidanströmung beider Rotorblätter aufgebracht. In a completely surprising way, in the case of the subject matter of the invention, the rotor blades running against the fluid automatically move into a low-friction (zero) position and then return to the operating position. The actuating forces are applied by the fluid flow of both rotor blades.

In Vorteilhafter Weise genügen hierbei zwei übereinader artgeordenten Blätter rotoren mit um 90° zue inander versetzten Blättern, um bei aus jj beliebiger horizontaler Richtung angreifende Strömungen eirie Drehung des ganzen Pananemonenrades zu erzeugen.Advantageously, two blade rotors arranged one above the other with blades offset by 90° are sufficient to generate rotation of the entire pananemone wheel in the event of currents attacking from any horizontal direction.

In den Unteransprüchen 2 bis sind vorteilhafte Ausgestaltungen des Erfindungsgegenstandes aufgeführt.Advantageous embodiments of the subject matter of the invention are listed in subclaims 2 to .

Die Erfindung ist in der Zeichnung anhand eines Ausführungsbeispieles veranschaulicht.The invention is illustrated in the drawing using an embodiment.

An einer Drehachse 1 sind zWe i Wellen 2 und 3 drehbar gelagert, art denen je um 90° zueinander Und übereinander Versetzt angeordnete Ro-; torblatter 4a und 4b, sowie 5a und 5b, frei schwenkbar aufgehängt sind. Wie in Fig. 3 in ihrer Ausgangsstellung zu sehen, sind die Rotor^ blätter einer Seite 4a und 5a zu denen der anderen Seite 4b lind 5b um je 90° schräg nach auswärts gespreizt, so daß sie zu einer mit
der Drehachse zusanrmenfa 11 enden vertikalen Ebene je einen Winkel von 45° einschließen.Two shafts 2 and 3 are rotatably mounted on a rotary axis 1, on which rotor blades 4a and 4b, as well as 5a and 5b, arranged at 90° to one another and offset one above the other, are suspended so as to be freely pivotable. As can be seen in Fig. 3 in their initial position, the rotor blades 4a and 5a on one side are spread outwards at an angle of 90° to those on the other side 4b and 5b, so that they form a
the axis of rotation together with the vertical plane 11 enclose an angle of 45°.

Jedem der Rotorblätter 4 und 5 ist an der Drehachse ein gefederter Anschlag 6 zugeordnet.Each of the rotor blades 4 and 5 is assigned a spring-loaded stop 6 on the axis of rotation.

Wie in Figur 1 dargestellt, wird das in der Zeichnungsebehe links liegende Rotorblatt 4a durch den anströmenden Wind gegen den zugeordneten Anschlag 6 angedrückt und das Rotorblatt 4b in freier Nullstellung angehoben. Die Drehmomente beider Rotorblätter 4a und 4b werden dabei zur Verstellung ausgenutzt.As shown in Figure 1, the rotor blade 4a on the left in the drawing plane is pressed against the associated stop 6 by the incoming wind and the rotor blade 4b is raised in the free zero position. The torques of both rotor blades 4a and 4b are used for adjustment.

Der zwischen der linken und der rechten Seite unterschiedlich große Strömungswiderstand versetzt das ganze Pananemonenrad in Drehung und es kommen dabei abwechselnd die Rotorblätter 4 und 5 in Arbeitsstellung .The different flow resistance between the left and right side causes the entire pananemone wheel to rotate and the rotor blades 4 and 5 alternately come into working position.

Die Drehbewegung wird durch einen nicht dargeste 111 ten Abtrieb zur Arbeitsleistung abgenommen.The rotary motion is taken up by an output (not shown) for work performance.
