Abstract
Abstract A magnetically actuated valve for constricting the flow of fluid through a fluid conduit wherein the valve is provided with tube means which extend laterally from the fluid conduit and contain fluid flow constricting elements which are magnetically driven into fluid flow constricting position within the fluid conduit to achieve an infinite variation between minimum and maximum flow conditions.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
151 words
A magnetically actuated valve for use in fluid conduit having an inlet and an outlet, said valve in combination with said fluid conduit and comprising: a first tube having slot means in one end in fluid communication with said conduit and the opposite end being closed; fluid flow constricting means including a plurality of spherical elements disposed within said tube and adapted to move axially therein; means within said fluid conduit and in alignment with the one end of said tube to limit the axial movement of said fluid flow constricting means disposed transverse to the extension of the longitudinal axis of said tube; and magnetic driving means disposed adjacent to said tube for applying a magnetic field to effect controlled movement of said fluid flow constricting means through said tube along the longitudinal axis thereof, and thereby provide for controlled variations between maximum and minimum fluid flow through said conduit.
Claim 2
Dependent Claim
151 words
A magnetically actuated valve for use in fluid conduit having an inlet and an outlet, said valve in combination with said fluid conduit and comprising: a first tube having slot means in one end in fluid communication with said conduit and the opposite end being closed; fluid flow constricting means including a plurality of spherical elements disposed within said tube and adapted to move axially therein; means within said fluid conduit and in alignment with the one end of said tube to limit the axial movement of said fluid flow constricting means disposed transverse to the extension of the longitudinal axis of said tube; and magnetic driving means disposed adjacent to said tube for applying a magnetic field to effect controlled movement of said fluid flow constricting means through said tube along the longitudinal axis thereof, and thereby provide for controlled variations between maximum and minimum fluid flow through said conduit.
