The development of piston hybrid power machines is prompted by their high economic characteristics. Performance indicators of such machines can be primarily improved by using seals that make a considerable difference in the fluid flow rate from the pump section to the compressor section and in reverse. A short description of the operation of a promising stepped slot seal is given. A mathematical model of the processes occurring in the working cavities and the seal of the piston hybrid power machine is outlined. The results of mathematical modelling of these processes and the characteristics of the machine under investigation are presented for various lengths of the stepped slot seal. An analysis of the obtained dependencies is performed. The conducted studies have shown that using stepped slot seals can increase flow and power characteristics of piston hybrid power machines.
