Abstract
A solenoid proportional valve includes a valve body (12) defining an inlet (14) and an outlet (16) for a fluid flow through the valve body, and an armature (22) that is moveable along a longitudinal axis from a first closed position to a second open position to control the flow of fluid through the valve. The valve further includes a flux can (32) and a solenoid coil (30) positioned within the flux can. When the solenoid coil is energized, a magnetic field causes the armature to move away from the first position against the valve body, thereby opening the valve. The valve further includes a flux washer (28) that acts as a spring pivot for a spring (26) having an outer edge that is secured by the flux washer. When the solenoid coil is energized, the magnetic field causes the armature to move away from the first position against the spring force of the spring, thereby opening the valve.
