摘要： A module solenoid valve (14) includes a valve body (16) defining an inlet opening (22) and an outlet opening (20). The valve body includes a valve seat (18) at a distal end thereof. A valve member (24) controls flow of fuel through the outlet opening. A movable armature (26) is coupled with the valve member such that movement of the armature moves the valve member between a closed position and an open position. A stator (38) is associated with the armature. An electromagnetic coil (36) is associated with the stator and armature for causing movement of the armature towards the stator. A spring (32) biases the armature and thus the valve member to the closed position. The spring provides a spring force that is greater than a first, normal hydrostatic force applied to the valve seat, but less than a second, overpressure hydrostatic force applied to the valve seat.

摘要： A fuel injector including a body having an inlet, an outlet, and a fuel passageway extending from the inlet to the outlet along a longitudinal axis. An armature is proximate the inlet of the body. A needle is operatively connected to the armature. A seat is proximate the outlet of the body. A guide member is disposed within the body, the guide member including an aperture that guides the needle. A flat metering disk is disposed between the seat and the guide member, the flat metering disk including a central aperture, a perimeter, and a plurality of slots. Each of the plurality of slots is disposed about the central aperture and extends from the central aperture toward the perimeter to define a volume. The plurality of slots are configured so that the volumes of two of the plurality of slots are non-uniform, and/or the plurality of slots are non-uniformly disposed about the central aperture.
