Abstract
An electrically operated fluid control valve unit is associated with a moving-coil linear motor which includes the quantity of fluid flow across the tubular core, a permanent magnet for providing magnetic flux through the tubular core, a permanent magnet for providing magnetic flux through the tubular core, a moving-coil wound on the bobbin across the magnetic flux of the magnet to provide a linear force on the bobbin, and a pair of conductive springs connecting the moving-coil to an electric control circuit and biasing the bobbin toward its initial position. Each of the springs is insulated from one another and from the valve housing, the tubular core and the like to prevent from unexpected short of the springs.
