Rotary Vane Vacuum Pumps

The rotary vane pump contains a rotating cylinder mounted off-axis. The off-axis rotor causes the volume between the vanes and the body to vary during each half turn. The gas inlet port is positioned to increase the volume behind the last vane that passed, allowing gas to expand into it until the next vane passes. The moving rotor then compresses the gas against the final exhaust valve until it exceeds atmospheric pressure forcing open the exhaust valve.
