摘要: A fuel injection pump having an inlet metering valve with separate primary and boost ports for metering an intake charge of fuel to a charge pump, limit means for separately establishing a maximum charge limit of the charge pump and a lesser metered charge limit through the primary valve port, a multiple position hydraulic actuator for selectively setting an all-speed governor at each of a plurality of speed settings and a solenoid control for selectively positioning the hydraulic actuator and activating the boost port to switch the charge limit to said maximum limit at certain speed settings.
