Claim Text:
1. A solenoid valve assembly comprising: an armature having a longitudinal axis, the armature being moveable along the longitudinal axis from a first position to a second position; and a bobbin including a solenoid coil configured to electromagnetically move the armature along the longitudinal axis from the first position to the second position when energized; wherein the armature has an ovular transverse cross section; the solenoid valve assembly further comprising a flux coupler and a flux bracket, wherein a magnetic circuit to electromagnetically move the armature comprises the flux coupler, the flux bracket, and the armature; wherein the flux bracket has a pole piece that limits the movement of the armature along the longitudinal axis, thereby determining a stroke length of the armature; and wherein one of the flux coupler or flux bracket includes a plurality of ridges and the other includes a plurality of slots, wherein the flux coupler and flux bracket are slidably moveable relative to each other to adjust the position of the pole piece.
