Abstract
BOMBA DE ALETAS DE VACIO, ESPECIALMENTE PARA VEHICULOS DE MOTOR DE COMBUSTION INTERNA. COMPRENDE UNA CARCASA (1) CON UN ORIFICIO (2) EN EL QUE GIRA UN ROTOR (3) ALOJADO EXCENTRICAMENTE EN UNA CAVIDAD INTERNA EN LA QUE SE ENCUENTRA DISPUESTO AXIALMENTE UN CONDUCTO DE ASPIRACION (17) Y SE COMUNICA MEDIANTE UNA RANURA RADIAL (25, 25 ) CON UNA CAVIDAD DE TRABAJO. EXISTE UN CONDUCTO DE ASPIRACION DE ACEITE PARA LA BOMBA DE VACIO, A UN NIVEL MAS ELEVADO QUE EL CONDUCTO DE ASPIRACION PARA LA ALIMENTACION DE ACEITE AL MOTOR.
