Rotary vane compressor’s operation
As the diagram shows, when the rotor is rotating under an
external force, due to the synergism of centrifugal force and the
oil pressure difference on the five vanes of the rotor, their edge
clings to the cylinder wall. Because the fixed cylinder is oval
shaped, while rotating on the rotor, the rotor vanes spread and
retract according to the cylinder's geometrical shape, which in
turn makes the crescent shape consisting of the cylinder, vanes,
etc. to change continuously, so as to achieve the functions of
suction, compression, and exhaustion.
