Abstract

Un rotore per motore pneumatico comprendente una cavità statorica (2) in cui è girevolmente inserito il rotore (5), comprende un corpo (7) sostanzialmente cilindrico nel quale è praticata una successione circonferenziale di intagli radiati (8) estendentisi per l'intera lunghezza del corpo cilindrico (7) stesso, e formanti altrettante sedi per rispettive pale radiali (9) scorrevolmente inserite in detti intagli (8); a ciascuno di detti intagli (8) è associato almeno un rispettivo condotto (11) praticato in detto corpo cilindrico (7) separatamente ed in anticipo rispetto a detto intaglio (8) nel senso di rotazione del rotore (5) e comunicante con la cavità statorica (2) e con il fondo del rispettivo intaglio (8), per permettere ad un fluido in pressione di penetrare nel fondo di detti intagli (8) per sollecitare dette pale (9) in una condizione di impegno forzato con una superficie interna di detta cavità statorica (2).(Figura 1).A rotor for pneumatic motor comprising a stator cavity (2) in which the rotor (5) is rotatably inserted, comprises a substantially cylindrical body (7) in which a circumferential succession of radiated notches (8) extending the entire length is practiced of the cylindrical body (7) itself, and forming as many seats for respective radial blades (9) slidingly inserted in said notches (8); each of said notches (8) is associated with at least one respective conduit (11) made in said cylindrical body (7) separately and in advance of said notch (8) in the direction of rotation of the rotor (5) and communicating with the cavity stator (2) and with the bottom of the respective notch (8), to allow a pressurized fluid to penetrate the bottom of said notches (8) to urge said blades (9) in a condition of forced engagement with an internal surface of called stator cavity (2). (Figure 1).
