Abstract
Una bomba de tornillo excéntrica, que comprende un rotor (70) que se extiende a lo largo del eje longitudinal (1) del rotor desde un extremo impulsor hacia un extremo libre, un alojamiento de estator (90) con una cavidad interna que se extiende a lo largo del eje longitudinal (1) desde una abertura de entrada de estator (90a) hacia una abertura de salida de estator (90b) y que está diseñada para incorporar el rotor (70), un motor impulsor (60) con un árbol impulsor que está acoplado con el rotor (70) para transmitir una torsión, una primera junta de cardán (22) que se coloca dentro de la transmisión de la torsión entre el árbol impulsor y el rotor, y una brida de salida de estator (100) que se dispone en dirección de flujo detrás del rotor (70). La brida de salida de estator (100) comprende un plano de conexión de brida (100´) que está orientado de forma no vertical al eje longitudinal.
