A parts feeder has a vortex chamber with a wall disposed generally symmetrically about an axis and into which bulk parts are fed. A vortex generator disposed at a narrow end of the chamber generates a spiral vortex that rises up the wall. Parts entrained in the vortex are separated and oriented by the vortex. Properly oriented parts are successively able to pass through an outlet port to exit the vortex chamber; thus continuously feeding parts. An opening extends through the vortex generator. Defective parts, oversize parts, and parts which are tangled or held together may readily be removed from the vortex chamber through the opening.
