摘要: A variable-discharge high pressure pump (10) for pressure-feeding fuel to a common rail (6) for use in a diesel engine (1). The pump has a plunger (18), a plunger chamber (19), a cam (17) for reciprocatively moving the plunger; an opening-out type electromagnetic valve (15) capable of opening and closing one end of the plunger chamber, a fuel reservoir (22), a check valve (23) communicating with the plunger chamber, and an inlet pipe (14) for supplying fuel to the fuel reservoir. Both the introduction of the fuel into the plunger chamber and the return of the fuel from the plunger chamber to the fuel reservoir are effected through the electromagnetic valve.

摘要: A variable discharge high pressure pump (7) for pumping a fuel into a common rail (4) of a common rail type fuel injection system has a plunger (15) reciprocable in a cylinder bore and a pumping chamber (16) defined between and end face of the plunger and the inner peripheral surface of the cylinder bore. A solenoid valve (30) has a valve member (38) movable into an open position in which the valve member is moved out of engagement with an associated valve seat (37) into the pumping chamber when the solenoid valve is deenergized. When the solenoid valve is energized, the valve member is moved into a closed position in which the fuel pressure in the pumping chamber acts on the valve member to urge the same into engagement with the valve seat. The plunger (15) is of a simple cylinderical structure free from any lead formed therein.
