Abstract (en)
[origin: WO2015021163A2] The system, according to one embodiment of the present invention, comprises a stationary coil linear motor to drive a valve with a stem comprising a ferromagnetic property. The linear motor moves the valve in respone to control governed by an electronic valve control computer. The valve is movable between a closed postiion at a selectable rate of both acceleration and speed for a selectable distance ("lift") to a second selectable open position, including all position variations between the fully open and fully closed states. Valve position, velocity and acceleration can be varied both during a valve stroke and from one stroke to the next, as controlled by the logic programmed on a non-transitive memory of the electronic valve control computer.
