Abstract
In un apparecchio a chiocciole co-rotanti avente due avvolgimenti di chiocciola che s'interfogliano fissati a piastre d'estremità che ruotano attorno ad assi paralleli, non allineati per produrre un moto orbitale relativo, una massa fissata ad almeno una delle chiocciole per migliorare la stabilità alla nutazione dell'organo a chiocciola. Preferibilmente, i mezzi di riduzione della nutazione includono una massa fissata ad una piastra d'estremità dell'organo a chiocciola per indurre uno squilibrio dinamico durante la rotazione dell'organo a chiocciola, creando un momento di bilanciamento o di moderazione sufficiente per compensare il momento indotto dalla pressione variante dei fluidi nelle varie camere di compressione durante la rotazione dell'organo a chiocciola.
