Abstract

PURPOSE: To provide a satisfactory stability of a control system by controlling an inputted horsepower of a hydraulic pump by use of a revolution number deviation signal which is used for controlling revolution speeds of an interval combustion engine.
CONSTITUTION: An internal combustion engine 1 is controlled by injecting a fuel from a fuel injection pump 6 to drive variable outlet hydraulic pumps 2, 3. A controller 12 sends a rack operation signal 12a to the fuel injection pump 6 on the bases of an operation signal 7a of a throttle lever, a revolution number signal 10a and a rack displacement signal 11a. The controller 13 outputs swash plate operation signals 13a, 13b on the bases of outside operation signals 8a, 9a of swash plate turning angle signals of hydraulic pumps 2, 3, swash plate turning signals 4a, 5a, discharge pressure signals 14a, 15a and a revolution number deviation signal 12b. Horsepowers may be thereby stably controlled.
