Work Process Calculation of Rotary Hybrid Energy Converting Displacement Machines

The paper presents the design of rotary hybrid displacement machines with a high indicator isothermal efficiency coefficient, with compressor section improved efficiency and reduced materials consumption. A mathematical model of the hybrid machine pump and compressor section work processes has been developed. The results of the indicator diagrams comparison obtained by computational and experimental methods are presented. In conclusion a schematic diagram of the rotary hybrid displacement machines with hydrodiode is given.
