Abstract
SYSTEME DE POIDS ET DE COMPLEXITE REDUITS. IL COMPREND PLUSIEURS ORGANES PIVOTANTS 40 QUI TRAVERSENT CE CARTER ET TRANSMETTENT UN MOUVEMENT DE ROTATION; UN DISPOSITIF DE MANOEUVRE 50 QUI FAIT TOURNER UN OU PLUSIEURS DE CES ORGANES PIVOTANTS; UN AGENCEMENT QUI PROVOQUE LA ROTATION PARTIELLE SYNCHRONE DE CES ORGANES PIVOTANTS LORS DE LA ROTATION PARTIELLE DE L'UN D'ENTRE EUX, CET AGENCEMENT COMPRENANT: A)UN BRAS 64 PORTE PAR CHACUN DES ORGANES PIVOTANTS ET TOURNANT AVEC LUI; B)UN ELEMENT ANNULAIRE DE MANOEUVRE 60, MONTE CIRCULAIREMENT POUR AVOIR UNE ROTATION PARTIELLE AUTOUR D'AU MOINS UNE PARTIE DU CARTER; ET C)UNE BIELLETTE 62 CORRESPONDANT A CHACUN DES BRAS, CES BIELLETTES AYANT UNE EXTREMITE 68 FIXEE DE FACON PIVOTANTE A UN BRAS ET L'AUTRE L'EXTREMITE 66 FIXEE DE FACON PIVOTANTE A L'ELEMENT ANNULAIRE DE MANOEUVRE; ET UN MOYEN 44, 46, QUI RELIE CHACUN DES ORGANES PIVOTANTS A L'ELEMENT COULISSANT ET PROVOQUE LE COULISSEMENT DE CET ELEMENT LORS DE LA ROTATION DE CES ORGANES PIVOTANTS. APPLICATION AUX MOTEURS A TURBINE A GAZ.REDUCED WEIGHT AND COMPLEXITY SYSTEM. IT CONSISTS OF SEVERAL SWIVEL ORGANS 40 WHICH CROSS THIS CASE AND TRANSMIT A ROTATIONAL MOVEMENT; A MANEUVERING DEVICE 50 WHICH ROTATES ONE OR MORE OF THESE SWIVEL PARTS; AN ARRANGEMENT WHICH CAUSES THE SYNCHRONOUS PARTIAL ROTATION OF THESE SWIVEL ORGANS DURING THE PARTIAL ROTATION OF ONE OF THEM, THIS ARRANGEMENT CONSISTING OF: A) AN ARM 64 CARRIED BY EACH OF THE SWIVEL ORGANS AND TURNING WITH IT; B) AN ANNULAR MANEUVER 60 ELEMENT, MOUNTED CIRCULARLY TO HAVE A PARTIAL ROTATION AROUND AT LEAST PART OF THE CRANKCASE; AND C) A LINK 62 CORRESPONDING TO EACH OF THE ARMS, THESE LINKS HAVING AN END 68 FIXED IN A PIVOT WAY TO ONE ARM AND THE OTHER THE END 66 FIXED IN A PIVOTING WAY TO THE ANNULAR MANEUVER ELEMENT; AND A MEANS 44, 46, WHICH CONNECTS EACH OF THE SWIVEL ORGANS TO THE SLIDING ELEMENT AND CAUSES THE SLIDING OF THIS ELEMENT DURING THE ROTATION OF THESE SWIVEL PARTS. APPLICATION TO GAS TURBINE ENGINES.
