Abstract
PURPOSE: To shorten a dimension of sealing unit, by such manner that in an end face of rotor and its oppositely directing face of refrigerant supply-return device, a ring-shape protrusion at one side and a pair of tube-shape magnets at another side be provided, with a magnetic fluid filled between each of the ring-shape protrusions and each pair of magnets.
