| (54) | Rotary positive displacement control system and apparatus |
| (57) 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.
