<p>A compressor driven by a vehicle engine through an electromagnetically engaged clutch, is alternatively driven by an electric motor through a permanent magnet coupling that is rendered operative when the clutch is disengaged. An axially displaceable armature common to both the clutch and the coupling, conducts magnetic flux emitted from the permanent magnets of the coupling and the electromagnetic coil assembly of the clutch along a common flux path.</p> |
