ABSTRACT:
The functions of a diverter valve and a variable orifice valve are combined in a single valve including an elongated magnetic member that is pivoted at a first end with a portion of the second end being positioned between opposed restrictors, a coil assembly for producing a magnetic field for selectively pulling the magnetic member toward one of the restrictors, sealing the restrictor it is pulled against thereby enabling the diversion of fluid flow, for example, from one nozzle to another, and further including a ball screw and torque motor attached to the first end of the magnetic member for selective movement thereof fore and aft, with the second end of the magnetic member being tapered and positioned in cooperative relation with respect to an orifice in a fluid inlet member whereby the fore and aft movement of the magnetic member controls the size of the orifice and the amount of fluid flow.
