Abstract:
A direct fuel injector (10) includes a body (12) having a passage between inlet and outlet ends. A seat (16) is at the outlet end and a closure member (28) is associated with the seat. A needle member (30) is associated with the closure member and is movable with respect to a pole piece (35) between a first, closed position and a second, open position. A spring (42) biases the needle member to the first position. An armature (32) is free-floating with respect to the needle member. An intermediate pole structure (38) is coupled with the needle member and is disposed between the pole piece and the armature and is decoupled there-from. An armature stop (40) is coupled to the needle member and is spaced from the intermediate pole structure. An electromagnetic coil (46) is associated with the pole piece, intermediate pole structure and armature. The injector reduces bounce of the needle assembly.
