Abstract
A single vane gas displacement apparatus comprises a stator housing with a right cylindrical bore enclosing an eccentrically mounted rotor which also has a radial slot in which is movably radially positioned a single vane. The vane is tethered to antifriction vane guide assemblies concentric with the housing bore. Then vane has a preselected center of gravity located proximate to the housing bore axis. An option is to have a port in said vane for ducting high-pressure gas to the inlet side to react against the rotor slot to reduce vane contact therewith.
