A Mathematical Model of the Working Processes of a Hybrid Power Displacement Piston Machine with Profiled Groove Seal

A mathematical model of the working processes of a hybrid displacement piston power machine with profiled groove seal is proposed. Calculation of the working processes in the compressor section in the presence of a liquid film under the piston and a “pump” course in the pump section and a piston seal is presented. The working processes for a hybrid displacement piston power machine with a smooth groove seal and with a profiled groove seal is calculated and the influence of a profiled groove seal on the working processes and the dynamics of the layer of liquid over the piston is demonstrated.
