Abstract (en)
A fuel pressure pump has a cylinder. A plunger is slidably received in the cylinder to define at one end of the cylinder a pressure chamber. The pressure chamber presses a fuel therein when the plunger moves in a direction to reduce a volume of the pressure chamber. A fuel supply passage is provided through which the fuel is led to the pressure chamber. A seal member is provided at a position other than a position where an inner surface of the cylinder and an outer surface of the plunger are slidably engaged. The seal member functions to make a hermetical sealing between the inner surface of the cylinder and the outer surface of the plunger. A first fuel holding space is defined by the inner surface of the cylinder, the outer surface of the plunger and the seal member. A first connection passage is provided that connects the first fuel holding space and the fuel supply passage. <IMAGE>
