Abstract
La présente invention concerne une pompe à griffes rotative, au moins une paire de rotors s'engrenant entre eux ayant la même forme dans une tolérance de plus ou moins 3 pour cent des rayons depuis les bords de leurs formes jusqu'à leurs centres de rotation, et présentant un taux uniforme nominal de changement de rayon avec un angle de rotation sur une partie convexe des griffes, et pouvant comporter plusieurs étages, l'épaisseur de chaque paire de rotors successifs ne variant pas dans le profil mais présentant une épaisseur correspondant au maximum à 20 % de l'épaisseur de la paire de rotors de premier étage multipliée par les produits inverses des taux de compression des étages précédents et un orifice d'évacuation étant au moins en partie découvert à n'importe quelle position de rotation, de la position où une paire de pointes de rotors à griffes s'engrenant entre elles sont à leur point d'approche le plus proche à celle où lesdites pointes de griffes sont à leur distance la plus éloignée, et ledit orifice d'évacuation étant au moins en partie relié à une région reliée aux pointes de rotors desdites griffes pendant lesdites positions de rotation, et l'orifice d'évacuation limite ainsi au moins une augmentation de pression dans ladite région.
