ABSTRACT:
A solenoid valve has a valve body in which a valve spool is slidably disposed. The valve spool has a central longitudinal opening in which a central core and a selectively energizable coil are coaxially positioned. The coil establishes a magnetic field when energized. The core and coil extend for approximately the full length of the valve spool such that during movement of the valve spool, a substantially constant air gap is maintained. The valve body has fluid passages formed therein. Fluid communication between the passages is controlled by linear movement of the valve spool along the coil and core inducted by the magnetic forces.
