摘要：
A high pressure pump has a fuel passage and a pump chamber. Fuel flows into the pump chamber through the fuel passage. The high pressure pump includes a valve member and a plunger. The valve member is movable along a movable axis in a substantially axial direction of the valve member for controlling an amount of fuel flowing into the pump chamber through the fuel passage. The plunger is movable substantially along a movable axis in a substantially axial direction of the plunger. The plunger is capable of pressurizing fuel in the pump chamber to discharge fuel in the pump chamber. The movable axis of the valve member is displaced from the movable axis of the plunger substantially in parallel with each other.
