Summary
In this paper, the leakage loss in the RV compressor which mainly occurs at the radial clearance between the rotor and the cylinder is analyzed theoretically. In comparison with the rolling piston type, the leakage loss at the radial clearance in the RV compressor is typically found to be 40% lesser than that of the former. Furthermore, the leakage loss can be significantly reduced by selecting a shorter configuration of the compressor, which is anticipated to yield good volumetric efficiencies of more than 95%. For a longer configuration, the leakage loss can be effectively minimized by employing the method of an eccentric cylinder (see also this Bulletin, references 2009-1496 and 1497).
