Abstract

Disposición de bomba/motor de engranajes, consistente en una caja en la que están dispuestas al menos dos ruedas dentadas que engranar, entre sí y una de las cuales está asentada fijamente sobre un árbol, mientras que la otra está soportada de forma flotante sobre una película de líquido en posición muy próxima a la pared interior de la caja, presentando los dientes de las ruedas dentadas unas superficies de cabeza, caracterizada porque las superficies de cabeza de la rueda dentada soportada de forma flotante presentan un espesor mayor que el de las superficies de cabeza de la rueda dentada apoyada sobre el árbol.
