ABSTRACT:
A hydraulic-controlled electronic governor employed in a fuel injection system is provided with a proportional pressure-reducing solenoid valve (10) capable of conducting a self-regulation of an input hydraulic pressure supplied from a hydraulic pressure source (30). Such pressure-reducing solenoid valve (10) is connected with a control rack (25) for controlling an amount of fuel injection, while interposed between the hydraulic pressure source (30) and a pressure input chamber (28) of a power piston/cylinder mechanism (22) for controlling the control rack (25), so that the input hydraulic force acting on one side of the piston (24) of the power piston/cylinder mechanism (22) balances the resilient force of a return spring (27) acting on the other side of such piston (24) so as to control the control rack (25) in its position.
