Analysis of theoretical and experimental results on the effect of injection pressure in the pump section on the working processes and characteristics of a piston hybrid power machine with a slotted seal of a stepped type

The paper presents the results of experimental and theoretical studies of a piston hybrid power machine with a slotted seal of a stepped type. A mathematical model of the working processes of the machine running in the pump section is presented. The analysis of the influence of the discharge pressure in the pump section on the characteristics of a piston hybrid power machine with a slotted seal of a stepped type that allowed to prove the efficiency of using a staged slit seal in the PGPM in comparison with a smooth seal, and also to determine the optimum operation of the PGPM at a discharge pump pressure in the interval 3-4 bar.
