Abstract

Una bomba, compresor o motor de engranajes helicoidales, que incluye un miembro interior con una forma de engranajes helicoidales externos que tiene n frentes de iniciación, un miembro exterior con una forma de engranajes internos cooperantes, que tiene n +- 1 frentes de iniciación, medios para soportar al miembro exterior y una conexión por engranajes para provocar una rotación relativa entre los miembros interior y exterior, caracterizado porque la conexión por engranajes comprende una primera rueda de engranajes dentados externamente montada en el miembro interior, una segunda rueda de engranajes dentados externamente asociada con el miembro exterior y una conexión por engranajes dentados asociada con dicha primera rueda y dicha segunda rueda para sincronizar las rotaciones relativas de dichos miembros interior y exterior, con lo cual dicha rotación relativa tendrá lugar independientemente de cualquier contacto entre las formas de engranajes helicoidales de los miembros interior y exterior.
