The rolling piston of the rolling-piston-type rotary compressors plays an important role in achieving distinction in mechanical efficiency. Before examining the mechanism by which the rolling piston effectively decreases the power losses due to the mechanical friction, this study presents the experimental data on the high mechanical efficiency and the rolling-piston dynamic behavior of a comparatively small colling-capacity rolling-piston rotary compressor. Furthermore, this study makes observations of the crankshaft, which was subjected to a long endurance test of about 2 000 hours, to examine the wearing conditions. It is concluded from this study that the mechanical efficiency is 90.3 %, the mean velocity of the rolling piston is 32 rpm and an excellent fluid lubrication is formed between the rolling piston and the crankpin.
