Research and development of a high-efficiency piston hybrid power machine with two suction valves

Main disadvantages of a piston hybrid volumetric power machine with two suction valves were analyzed. Based on the analysis, a fundamentally new scheme of such a machine with cyclic supply of the compressed gas into the suction cavity was developed to provide the necessary surface forces used to move liquid from the machine head along the cooling jacket to the cooling liquid source. Using the developed scheme, a 3D model of the piston hybrid volumetric power machine with two suction valves was created. Strength computation was performed in the SolidWorks software package, which showed that the resulting stress was not exceeding permissible values for the types of materials used. An experimental bench equipped with the measurement equipment was developed to study the machine main working processes and integral characteristics.
