Abstract

PURPOSE: To save fuel, by pivotally rotating a governer shaft of a injection pump so that the number of revolution decreases while a construction equipment such as a power shovel or the like is not operated.
CONSTITUTION: When a construction machine is operated, a throttle lever 2 is turned on to B1. Thereby a branch lever 6 is turned around a pin 13 through a rod 4 so that the branch lever comes in a position B2 and a speed control lever 10 is turned on to B3. Thereby the number of revolution of a engine 11 is set to the maximum. On the other hand, if a control lever is in the neutral position, the dydraulic oil in pumps 20a, 20b flows through by-pass passages 34a, 34b, high pressurized oil in the upper stream side of throttles 36a, 36b affects an oil chamber of a cylinder 17 and a piston 16 is moved to the right against the power of a spring 18. As the branch lever 6 is pushed by a rod, the branch lever 6 is turned around a pin 5 and positioned in the C2. Thereby a speed control lever 10 is turned to C3 than the governer shaft 12 is turned so that the number of revolution of the engine 11 decreases.
