Abstract:
A fuel delivery system, comprising:a fluid pump operable to pressurize a first fluid to a predetermined pressure; a pressure control valve coupled with the fluid pump to receive the pressurized first fluid, the pressure control valve operable to regulate the pressure of the first fluid, the pressure control valve comprising: a housing having a first and a second apertures, the first aperture operable to receive the first fluid and the second aperture operable to exhaust the first fluid from the housing; a seat disposed within the housing, the seat having a first side and a second side, and a first passage for fluid flow from the first side to the second side, the first passage operable to receive the first flow of fluid; a stator disposed within the housing, the stator having a first side and a second side, and a first channel coupling the first side of the stator with the second side, the stator having at least a first portion spaced a predetermined distance from the seat, the at least first portion of the stator and the seat defining a cavity within the housing, the second aperture of the housing coupling the cavity with an exterior of the housing; a one-piece non-magnetic poppet of a first material disposed within the housing and at least in part within the channel of the stator, the poppet operable to be actuated from a first position to a second position and from the second position to the first position, the first position being a position that allows a flow of the first fluid through the passage in the seat, and the second position being a position that restricts the flow of the first fluid through the passage in the seat; an armature disposed within the housing, the armature operable to directly actuate the poppet from the first position to the second position in response to the armature moving from a third position to a fourth position; and a coil of an electrically conductive material coupled with the housing, the coil operable to move the armature from the third position to the fourth position in response to receiving a current; a hydraulically actuated fuel injector operable to receive the first fluid, a fuel, and a trigger signal, the injector operable to transmit a predetermined amount of the fuel in response to the trigger signal and as a function of the pressurized first fluid; a fluid path coupled with the fluid pump, the pressure control valve, and the injector, the fluid path operable to transmit the first fluid from the fluid pump to the pressure control valve and the injector.
