ABSTRACT:
A rotary vane compressor includes two stator chambers allowing two compression strokes for each revolution of the rotor. The shape of the chamber walls is specifically designed through the use of a sine function to increase efficiency of breathing of the compressor by providing a larger initial starting volume which reduces to a smaller discharge volume. The invention further includes a vane guiding mechanism preventing the rotor vanes from falling into the bottom of their respective slots to prevent slamming of the vanes upon start-up of the compressor.
