Abstract (en)
[origin: JPH01193037A] PURPOSE: To enhance respondence to acceleration and deceleration by connecting a rpm adjusting lever with an adjusting spring via a drag spring and communicating a plurality of throttles in a damping member with a valve interior respectively via a plurality of check valves. CONSTITUTION: A drag spring 36 is supported by a rpm adjusting lever 32 of an injection quantity adjusting device 28 on one hand, and supporter by a lever arm combined with an adjusting spring 31 of a damping lever 37 rotating with a shaft 35 of the rpm adjusting lever 32 as the center on the other hand. The rpm adjusting lever 32 is abutted to a stopper 38 arranged on the damping lever 37. A throttle 47 of a damping piston 44 is connected to a pump interior 11, of a pump piston 13 via a check valve 46 opening toward a damping chamber 45. The damping chamber 45 is connected to the pump interior 11 by another throttle 48 via another check valve 49 closing toward the damping chamber 45.
