Abstract
A linear motor-actuated flow control valve includes spring means for biasing a bobbin controlling valve hole opening degree in mutually opposing directions, to hold the bobbin at a middle opened position when an electromagnetic coil wound on the bobbin is deenergized. The bobbin is driven against spring means force in any opposing directions to increase or decrease the opening degree by applying a positive or negative energizing current to the coil.
