The results of experimental studies of piston hybrid energy-generating machine having smooth and stepped slot seals are analyzed. It is demonstrated that stepped piston seal is much more effective than the smooth one and raises the delivery factor of the compressor section by more than 10%, reduces the average temperature of the cylinder-piston group by 2–3 K, and enhances volumetric efficiency of the pump section by 3–5%.
