METHOD AND APPARATUS FOR SOLENOID POSITION MEASUREMENT AND CONTROL
A method of control using the measurement of the inductance of the solenoid coil to predict the physical position of the armature within the stator coil. As the resistance of the windings will vary not only from unit to unit, but also with the temperature of the coil, it is preferable to continuously measure the resistance and compensate the calculations for the change in current. The use of solenoid position sensing through closed loop control of the sensing of the inductance and temperature produces highly accurate and repeatable control of the valve assembly.

A first disc of a dual butterfly valve is mounted on a first shaft, and a second disc of the dual butterfly valve is mounted to a second shaft coaxial with the first shaft. The first shaft is connected to the second shaft through a flexible member. When the first shaft is rotated, the first shaft rotates the first disc towards a closed position and the rotation of the first shaft is translated to the second shaft through the flexible member, building tension in the flexible member and causing the second disc to rotate to a closed position prior to the first disc. The first disc then rotates to a closed position. The flexible member permits some lag to be present between the first disc and the second disc in moving to the open or closed position.
