| titleOfInvention |
Thermodynamic systems including gear type machines for compression or expansion of gases and vapors |
| abstract |
Actual thermodynamic processes occuring in a system such as a heat pump or refrigeration plant are made to approach theoretical ideal processes, e.g. an isothermal (T0), by use of a multistage gear machine (1) as compressor and/or expander in the system, and conditioning, such as cooling, the system working fluid between sucessive stages in the machine. The individual stages of the gear machine each consists of a pair of meshing gears (I-IV), preferably cylindrical spur gears of equal diameter and diminishing width from stage to stage. |
