Description

       

   <EMI ID=1.1> 

  
L'invention se rapporte à un moteur éolien comprenant une roue dont les pales peuvent être déplacées autour de leur! axes au moyen d'un dispositif qui comprend une pompe actionnée par la roue du moteur éolien, et un&#65533; commande ou un moteur à piston alimenté par cette pompe et opérant le déplacement ou réglage des pales, le refoulement ou débit de la pompe étant interrompu automatiquement lorsque les pales se trouvent dans la position de travail, efin d'épargner de l'énergie.

  
On connaît un moteur éolien dans lequel, en cas de ten pête, un dispositif du type susdit fait pivoter la roue d'un bloc hors de sa position perpendiculairement au vent. L'interruption du refoulement de la pompe a lieu alors grâce à ce que le cylindre de la pompe est muni d'une soupape d'évacuation d'air, qui est maintenue ouverte par un ressort, à rencontre  <EMI ID=2.1>  des conduites etc., qui ont pour conséquence que les pales quittent peu à peu la position de travail, ne peuvent pas nui:

  
 <EMI ID=3.1> 

  
butée devient inactive, la pompe est amenée à refouler et que les pales sont mises de nouveau dans la position de travail.

  
Le moteur à piston pour le déplacement ou réglage des pales doit en principe fournir déjà de grandes forces de dépit

  
 <EMI ID=4.1> 

  
certaine dépense d'énergie. De ce fait, il faut que la pompe,  <EMI ID=5.1> 

  
Ce déplacèrent est accompli par le dispositif comprenant la

cette pompe. Cette dernière est réalisée sous la forme d'une pompe à excentrique et est commandée pur 1' intermédiaire de

   <EMI ID = 1.1>

  
The invention relates to a wind motor comprising a wheel whose blades can be moved around them! axes by means of a device which comprises a pump actuated by the wheel of the wind motor, and a &#65533; control or a piston motor powered by this pump and operating the displacement or adjustment of the blades, the delivery or flow of the pump being automatically interrupted when the blades are in the working position, in order to save energy.

  
A wind motor is known in which, in the event of a storm, a device of the aforementioned type rotates the wheel of a block out of its position perpendicular to the wind. The pump discharge is then interrupted by the fact that the pump cylinder is fitted with an air discharge valve, which is held open by a spring, against <EMI ID = 2.1> of the pipes, etc., which result in the blades gradually leaving the working position, cannot harm:

  
 <EMI ID = 3.1>

  
stopper becomes inactive, the pump is forced to discharge and the blades are put back into the working position.

  
In principle, the piston motor for moving or adjusting the blades must already provide high resistance forces.

  
 <EMI ID = 4.1>

  
certain expenditure of energy. Therefore, the pump, <EMI ID = 5.1>

  
This displacement is accomplished by the device comprising the

  
 <EMI ID = 6.1>

  
this pump. The latter is made in the form of an eccentric pump and is controlled through the intermediary of

  
 <EMI ID = 7.1>

  
piston is mounted on the replacement rod 6 and has

  
 <EMI ID = 8.1>
