Abstract
Una bomba de engranajes (110) que comprende: una carcasa (112) que tiene paredes internas (114) que definen un conducto de entrada (116), un conducto de salida (118) y una cámara de engranajes (120) dispuesta entre el conducto de entrada y el conducto de salida; un primer y segundo engranajes (122, 123) de bomba soportados en forma rotatoria dentro de la cámara de engranajes, en que el primer y segundo engranajes de la bomba tienen dientes engranados entre sí; y zonas de compresión (126, 127) definidas entre cada uno de los engranajes de la bomba y las paredes internas de la cámara de engranajes, caracterizada porque cada una de las zonas de compresión (126, 127) tienen un grosor no uniforme a lo largo de una dirección longitudinal de los engranajes de la bomba, disminuyendo el grosor no uniforme desde un lugar situado entre los extremos opuestos axialmente de los engranajes de la bomba hacia cada uno de los extremos de los engranajes de la bomba.
