Abstract
An idle air control valve (11) for a vehicle includes a stator assembly (12) and a rotor assembly (26) operatively associated with the stator assembly and mounted for rotation with respect to the stator assembly. A shaft (36) is restricted from rotation and is associated with the rotor assembly such that rotation of the rotor assembly causes linear movement of the shaft. A pintle (38) is associated with a distal end of the shaft for linear movement therewith. A journal (28) is associated with the rotor assembly and is constructed and arranged to support and permit rotation of the rotor assembly relative to the stator assembly. Lubricant (30) is provided between a surface of the journal and a surface of the rotor assembly.
