Title: MAGNETIC FLOW CONTROLLER
Abstract:
An electromagnetic flow control apparatus (20) includes a fluid flow conduit (26), a magnetic membrane (21), and a plurality of discrete sources of selectably variable magnetic fields (22, 27'), such as electromagnets, arranged in an ordered array, to drive the membrane (21) in a desired manner to control the flow of fluid in the conduit. The membrane (21) can preferably be driven between two extreme positions wherein the flow of fluid in the conduit is totally unrestricted in the rest position of the membrane and wherein the flow is highly restricted or stopped completely in the maximum deformation of the membrane radially inward.
