INPUT LIMITING DEVICE OF OIL HYDRAULIC PUMP DRIVEN BY INTERNAL-COMBUSTION ENGINE

摘要: PURPOSE:To prevent the input torque of an oil hydraulic pump from substantially decreasing so as to perform good control when target speed internal-combustion engine is increased, by controlling a minimum value in accordance with differentiated output engine. CONSTITUTION:A detection signal Ne detector 8 1 function generator 15 through differentiator 14, and outputs distribution, increase pump, corresponding value. Then value, being compared deviation between set lever 7 selective circuit 17, horsepower control-function 12. This 12, small delivery capacity extent not excessively 3, capacity-control mechanism 4 3 13.
