An adjustable electromagnetic fluid flow control valve includes: a tubular member of non-magnetisable material.. One end of the tubular member is forming an inlet and serves as the main entry port for: gases or other fluids entering the valve. The opposite end of the tubular member is forming an outlet The valve includes at least one annularly configured electromagnetic coil which is surrounded from outside and partially inside by a core preferably built from ferrous laminations. The coil is connected to a power supply and can be energised by the power supply under control of a controller: A disk occluder of a magnetic material has diameter corresponding to the internal diameter of the tubular member. The occluder is disposed Within the tubular member and occludes the fluid flow when is positioned perpendicular to the longitudinal axis of the tubular member. The occluder rests on a supporting non-magnetic- member with at least one passageway for fluid flow. The occluder is pressed against the supporting member by a spring. All spring- loaded members of the valve are locked In place between two inner locking members rigidly mounted within the tubular member. The magnetic torque, exerting influence on the occluder increases or decreases With changes in the electric power to the coil and this changes the cross-sectional area of the flow pass. |
