Abstract: In order to improve the space utilization rate of rolling
piston compressors, a new cavity is hollowed out in its rotor, and a
stator, which is concentric with the cylinder, is installed in the
cavity with a vane. So the inner wall of the hollow rotor and the outer
wall of the stator enclose a new working cavity. Thus the space
utilization rate and the displacement for the machine could be increased
while the diameter of its cylinder remains constant. Compared with the
traditional rolling piston compressor, the proposed one has higher
effective volume and will be widely applied.
Key words: Compressor Rolling piston Odd-cylinder dual-cavities
