Abstract:  
The present invention relates to valve mechanisms for magnetic fluid conduits and to uses thereof, for example, shock absorbers. The general object of the present invention is to provide such valve mechanisms for magnetic fluid conduits which are readily and economically produced on a mass production basis and easily assembled and installed to allow efficient "valving" of the flow of magnetic fluids there-through by means of controls in the electrical circuits of electromagnets of such valve mechanisms; such valve mechanisms featuring location of the opposed magnetic poles to cause the lines of flux to traverse the path of flow substantially normal thereto to attain the valving effect with flow in either direction and preferably minimized spacing of the magnetic poles for greatest effectiveness of the magnetic field.
