What is it about?
The hydropneumatic design of the test bench is provided. A mathematical description of the working processes that occur in the seal is presented. Results of theoretical and experimental studies and an analysis of the influence of the angular spin rate of the crankshaft on the working processes and operational properties of a hybrid piston power machine are presented.

Why is it important?
The need to increase the efficiency of a hybrid piston power machine is critical. One of the most advanced methods of increasing the efficiency of the machine is to achieve a large difference between the flow rates of liquid from the piston section and into the compressor section, and conversely, which makes it possible to achieve effective cooling of the compressed gas and the cylinder-piston group of a hybrid piston power machine and to decrease the dead space of the compressor section. The proposed solution will increase the efficiency of a hybrid piston power plant.
Perspectives
The functional principle of such a seal consists in a gradual decrease in the hydraulic resistance as the piston travels from the upper to the lower dead point (in the course of processes of reverse expansion and suction in the compressor section), which tends to increase the flow rate of the liquid from the pump section into the compressor section, and in gradual increase in the hydraulic resistance as the piston travels from the lower to the upper dead point (in the course of compression and discharge processes in the compressor section), which hinders discharge of liquid from the compressor section into the pump section.
