ABSTRACT:
A fuel injection pump of rotary type for use in an internal combustion engine, which incorporates a fuel injection control mechanism comprising a mechanical governor arrangement through a mechanical coupling of self-centering and vibration absorbing character in the driving train of such rotary components as a face cam shaft for driving a plurality of plunger pumps disposed radially and a control shaft for axially shifting a metering sleeve. The metering sleeve is specifically designed for adjusting the opening areas of a plurality of metering orifices defined radially in the inner circumferential surface of a barrel of the fuel injection pump for communication with the radially disposed plunger pumps. The governor is designed for adjusting axially the location of the metering sleeve relative to the metering orifices so as to change the opening areas of such metering orifices in response to the changes of the rotating number of the driving train, and also designed for compensating the basic operating position of the governor in relation to the operating status of a booster adapted to respond to the changes of air intake pressure of the engine, so that proper fuel injection may be attained with a constant delivery of the plunger element thereof in the range of small flow rate of the fuel.
