A single vane gas displacement apparatus comprises a stator housing (10) with a right cylindrical bore (12) enclosing an eccentrically mounted rotor (18) which also has a radial slot (176) in which is movably radially positioned a single vane (75). The vane is tethered to antifriction vane guide assemblies (40, 45, 81 and 55, 60, 81') concentric with the housing bore. The vane has a preselected center of gravity located proximate to the housing bore axis. An option is to have a port (75P) in said vane for ducting high-pressure gas to the inlet side to react against the rotor slot to reduce vane contact therewith. |
