Abstract
A solenoid assembly of a fuel pump includes a housing; a pole piece disposed within the housing; an armature assembly movably disposed within the housing and including an armature and a plunger; and a coil disposed within the housing. A plurality of metal disks are disposed in a stacked arrangement, coupled to the pole piece and situated so as to be impacted by the armature during a full stroke of the armature assembly. The solenoid assembly further includes at least one fluid path in fluid communication with the region surrounding the metal disks, the at least one fluid path configured such that only a portion of a secondary swept volume of fuel associated with the armature assembly during operation of the fuel pump passes through the region and decelerates the armature assembly when the armature assembly moves towards the pole piece responsive to a current passing through the coil.
