Rotary positive displacement control system and apparatus

Abstract

A rotary positive displacement control system and apparatus includes a transmission assembly, at least a compression assembly and buffer assembly, and an expansion assembly, the buffer assembly disposed between the compression and expansion assembly. The compression assembly includes multiple compression rotors with lobes intermeshing with each other, and the expansion assembly including expansion rotors with lobes intermeshing with each other. An intake and exhaust port respectively located at the compression assembly and expansion assembly. The buffer assembly has a buffer chamber being able to efficiently lead compressed gases to the expansion assembly; meanwhile, residual gases can be discharged from a first and second exhaust slots both disposed on the expansion assembly. The buffer chamber can adjust air compression ratio during process of compression to completely mix vortexes and fuel generated from a high-pressure air stream; after explosions and expansion, power output is transmitted through transmission shafts directly.
