Abstract

Systems (10) are provided for electromagnetic actuation of a valve mechanism. A valve (12) is linearly moveable between a first closed position (20a) and a second open position (20b). A first spring (28) is compressed when the valve is in the first closed position, and a second valve spring (30) is compressed when the valve is in the second open position. An electromagnetic actuation assembly (36a, 36b) and a permanent magnet (26) is combined with the valve, such that the valve is latchable in either a closed or open position, and is readily movable between positions through application of energy to the electromagnetic circuitry. The electromagnetic circuitry is controllable to increase or decrease the local magnetic flux, such as to promote movement of the valve, or to provide a soft landing of the valve at either end of movement. Some system embodiments provide energy recovery, feed back, and/or feed forward sensing and control.

1. A valve system, comprising: a valve comprising a valve stem linearly movable between a first closed position and a second, open position; a first spring; a second spring; a first electromagnet assembly; a second electromagnet assembly; and a permanent magnet clapper affixed to the valve stem; whereby the first spring is compressed and the valve is moved toward the first closed position as the permanent magnet approaches the first electromagnetic assembly, and whereby the second spring is compressed and the valve is moved toward the second open position as the permanent magnet approaches the second electromagnetic assembly.
2, The valve system of Claim 1 , further comprising: means for providing energy to at least one of the electromagnet assemblies to increase a local magnetic field.
3. The valve system of Claim 1 , further comprising: means for providing energy to at least one of the electromagnet assemblies to decrease a local magnetic field.
