摘要： A fuel pressure regulator is provided. The fuel pressure regulator includes a body forming an inlet and an outlet, a seal element positioned intermediate the inlet and the outlet, an armature positioned to apply force to the seal element, and a solenoid coiled around the armature, wherein excitation of the solenoid causes a change in at least one of a position of the armature relative to the seal element and a force applied by the armature to the seal element to vary a regulated fuel pressure set-point at which fuel flows through the outlet.
