METHOD FOR CONTROLLING HIGH-PRESSURE FUEL SUPPLYING PUMP, AND HIGH-PRESSURE FUEL SUPPLYING PUMP EMPLOYING SAME

摘要

The purpose of the present invention is to provide: a method for controlling a high-pressure fuel supplying pump, which is capable of effectively reducing noise generated when an electromagnetic suction valve is opened; and a high-pressure fuel supplying pump employing the same. The method controls the high-pressure fuel supplying pump provided with: a suction valve 30 that is disposed at the suction side of a pressurizing chamber 11; a rod 35 that urges the suction valve 30 in the valve opening direction; and an anchor 36 that is drawn by a magnetic attraction force generated by energization of a solenoid and moves the rod 35 in the valve closing direction, wherein when the anchor 36 moves in the valve opening direction, a first drive current is applied to the solenoid for a predetermined time period, and then, a second drive current, which is greater than the first drive current, is applied to the solenoid for a predetermined time period, whereby the abovementioned purpose can be achieved.
