    Abstract: A valve (100) comprises a barrel (104) having a central bore (110), an inlet (112), and an outlet (114, 116), and a spool (120) disposed for motion within the central bore, including a ball tip (128), a metering edge (130), and a bore (132). The spool is moveable between a closed position, wherein the ball tip engages a seat (142) to prevent fluid flow through the inlet and the metering edge is disposed in a lower chamber (148) of the central bore to prevent the fluid flow through the outlet, and an opened position, wherein the tip is spaced apart from the seat to permit fluid flow through the inlet and the spool bore into an upper chamber (154) of the central bore to equalize pressure on the spool, and the metering edge is disposed in a flow path of the outlet to permit fluid flow through the outlet.

    Abstract: A fuel injector includes an injection control valve having a stator core that is electrically isolated from surrounding parts such as a stator housing. The stator core includes a first annulated wall having an inner surface, a second annulated wall having an outer surface, a radially extending wall connecting the first and second annulated wall, and a radially extending slot extending through the first annulated wall, the radially extending wall, and the second annulated wall. The stator core may include a limited number of contact points with the stator housing. Alternatively or additionally, an electrically insulating material may be placed between the stator core and the stator housing.
