ABSTRACT:
A rotary spray head comprises a shaft in a longitudinal cavity in a body with spray means mounted on one end of the shaft and projecting axially from the body. At least one magnetic bearing is provided to support the shaft at least partially in the radial direction. The magnetic bearing comprises two magnetized annular parts respectively forming a stator and a rotor. These are in face-to-face relationship to each other so as to define between them an airgap occupying a plane substantially perpendicular to the main axis of symmetry of the shaft. They have respective main axes of symmetry coincident with that of the shaft.
