Fuel system for internal-combustion engine, has hydraulically controlled adjusting device including damping unit that exerts braking force on control piston, where force depends on movement speed of piston

摘要

The system (10) has a hydraulically controlled adjusting device (20) including a control piston with a control surface limiting a pressure chamber. The chamber is connected with a region (32a) of a control line (32), where the region lies upstream of a throttle (34). The piston has a control surface that limits a pressure chamber connected with a region (32b) of the control line, where the region (32b) lies downstream of the throttle. The adjusting device has a damping unit that exerts a braking force on the piston, where the force depends on the movement speed of the piston.
