Résumé

Aiming at reducing the excessive friction loss of conventional vane compressor between vane tip and cylinder wall, this paper proposed a novel vane compressor. By using rolling bearing instead of cylinder, the vane tip only contacted the bearing inner ring, and the inner ring rotated with vane. Thus the sliding friction between vane tip and cylinder was converted into rolling friction of the
bearing, which could significantly reduce the mechanical power consumption. The structure and characteristics of the novel vane compressor were introduced, then the mechanical power consumption of the two kinds of compressors were theoretically calculated. The calculation results indicated that, under the design condition, vane tip power consumption of the novel vane
compressor was reduced by 86.5% comparing with that of the conventional one. The experimental results showed that total power consumption of the novel vane compressor was reduced by 5.53% comparing with that of the conventional one.
