An apparatus for controlling the engine of a hydraulically driven vehicle includes a transmission mechanism having a loose spring and connecting a fuel control lever operationally to a governor control lever, a decelerator cylinder including a spring having a slightly larger spring force than the loose spring and disposed on the opposite side of a piston from a hydraulic fluid chamber and a piston rod connected to the transmission mechanism by a yoke having a slot, an electromagnetic valve for supplying a hydraulic fluid from a hydraulic pump driven by the engine to the hydraulic fluid chamber in the decelerator cylinder or interrupting its supply, and an electric circuit for opening or closing the electromagnetic valve. As long as no hydraulic pressure acts on the piston, the spring in the decelerator cylinder maintains the governor control lever in its deceleration position even if the fuel control lever is turned to its full engine speed position, while the operation of the fuel control lever is transmitted directly to the governor control lever if a hydraulic pressure acts on the piston. |
