| 摘要 |
A solenoid actuated fuel injector (10) includes a valve body (14), a valve seat (18), a seating surface (22), a fuel outlet opening (24), a fuel tube (26) for conducting pressurized fuel into the valve body against the seating surface, a spherical valve ball (34) moveable between a closed position and an open position to allow fuel flow through the outlet opening, a spring (36) for biasing the valve ball toward the seated position, an armature (38) axially moveable in the valve body and including a valve ball capturing member (40) at an end proximate the seating surface, the valve ball capturing member being engageable with the ball outer surface adjacent the seating surface and a solenoid coil (44) operable to draw the armature (38) away from the seating surface, thereby moving the valve ball (34) to the open position.
