Abstract
Depressore (1) rotativo a palette, comprendente un corpo di supporto (2) per un alberino (11) di azionamento rotativo di un rotore (13) portante tre palette (15) equispaziate angolarmente e scorrevoli entro cavità radiali (14) realizzate nel rotore (13). L'estremità esterna delle palette (15) è tenuta a contatto di una superficie interna di una cavità di lavoro (10) realizzata nel corpo (2), così da realizzare camere di lavoro (48) a volume variabile tra le palette (15), passanti tra rispettive aperture di aspirazione e di scarico. Le estremità interne delle palette (15) sono contemporaneamente a contatto di una coppia di elementi (70) a corona anulare, che sono disposti in rispettivi vani (71) nelle due zone di testa del rotore mobili in piani perpendicolari all'asse del rotore.
