What is it about?
The main geometric and operational parameters of non-contact gap seals of various designs used in piston hybrid power machines are analyzed. Based on the analysis of the equations of incompressible viscous fluid flow in a gap seal, the main independent variables that have the greatest impact on the fluid flow through the gap seal and the ranges of their change are determined. The results obtained will be of primary interest to designers and engineers of piston hybrid power machines, as well as piston compressors and pumps.

Why is it important?
The resulting synergistic effect allows for a significant improvement in the efficiency of their operation, namely: improved cooling of the compressed gas; reduced leaks and overflows of the compressed gas; reduce the work of friction forces in the piston seal; eliminate the so-called dead space in the compressor section; increase the cavitation reserve in the pump section; improve the efficiency of compression and injection of liquid by supplying heat from the compressor section.
Perspectives
Based on the analysis of the main geometric and operational parameters of gap seals used in piston hybrid power machines, the following ranges of changes in independent parameters can be identified, which can be primarily used in the design of piston hybrid power machines, as well as piston compressors and pumps, or for performing parametric analysis
