Abstract: This paper investigated eccentricity characteristics of the piston and its influence on leakage flowrate of the labyrinth seal. The eccentricity of the piston and the dynamic pressures in the cylinder and in the labyrinth cavities were tested on a labyrinth piston compressor. Then, a 2-dimension transient flow model was built for the fluid flow in labyrinth seal. The labyrinth leakage flow rate with and without piston eccentricity was obtained and compared.

Keywords:  labyrinth compressor, labyrinth seal, leakage flow, piston eccentric motion
