In this paper, a new promising scheme of a two-cylinder single-stage piston hybrid power machine with fluid flow due to vacuum at suction is examined. A prototype is developed, and an experimental stand is created. An analysis of the influence of the coolant flow on the working processes of the machine is carried out theoretically and experimentally. The results obtained show that an increase in the coolant consumption leads to a decrease in the input technical work in the process of compression, an increase in the output technical work in the process of decompression, a reduction of the work losses in the process of discharge and an increase of the work losses in the process of suction. Based on the conducted experimental studies it is established that the optimal indicative value of the efficiency for the experimental machine under study is in the range of 300 – 400 ml/min and the relative increase in the indicative efficiency is within 7 %.
