Magnetic Fluid Control Valve

The valve controls the flow of magnetic fluids by creating a magnetic field across a fluid conduit to impede or stop the flow of fluid, depending upon the strength of the applied field.

Fluid flows from an inlet duct 10, through a conduit 11, a restricted gap 12 formed between a magnetizable casing member 13 and a core 14, and through an outlet 15. Normally, fluid flows freely through the path but, when a magnetizing winding 16 around the core 14 is energized, a magnetic field is created across the gap 12. This orients the magnetic fluid particles with the field to thicken or solidify the fluid, depending upon the strength of the applied field.

Core 14 is threaded to member 18 and is rotated by knob 17 so as to provide for adjusting the size of gap 12.
