Abstract
A non-contact vane-type fluid-displacement machine includes a stator housing having an annular interior surface defining an interior bore and a rotor supported in an eccentric position in the interior bore of the stator housing relative to the annular interior surface thereof to undergo rotation relative to the stator housing about a central rotational axis. The rotor has at least one slot radially defined therein relative to the rotational axis. The machine also has at least one vane disposed in radial slot of the rotor. The vane is mounted to the rotor to undergo reciprocable movement in a radial direction relative to the rotational axis of the rotor such that an outer tip portion of the vane is maintained in a non-contacting substantially sealed relationship with the interior surface of the stator housing. Improved features of the machine relate to a plurality of low profile vane guide assemblies for positioning the vanes of the machine.
