The invention provides a toroidal intersecting vane machine incorporating intersecting rotors to form primary and secondary chambers (208, 202) whose porting configurations minimize friction and maximize efficiency. Specifically, it is an object of the invention to provide a toroidal intersecting vane machine that greatly reduces the frictional losses through meshing surfaces without the need for external gearing by modifying the function of one or the other of the rotors from that of "fluid moving" to that of "valving" thereby reducing the pressure loads and associated inefficiencies at the interface of the meshing surfaces. The inventions described herein relate to these improvements.

La présente invention concerne une machine à ailettes à intersection toroïdale comprenant des rotors à intersection qui forment des chambres primaire et secondaire (208, 202) dont les entrées et les sorties présentent des configurations qui réduisent au maximum le frottement et augmentent au maximum l'efficacité. De manière plus spécifique, un objectif de cette invention est de produire une machine à ailettes à intersection toroïdale qui réduit fortement les pertes par frottement du fait de l'existence de surfaces d'engrènement ne nécessitant pas d'engrenage externe, qui modifient le fonctionnement d'un rotor ou de l'autre et le font passer d'un état de 'circulation de fluide'' à un état de 'régulation'', ce qui réduit ainsi les charges de pression et l'inefficacité associée au niveau de l'interface des surfaces d'engrènement. Les inventions présentées se rapportent à ces améliorations.
