Abstract: A valve seat has an inner passage and outer passages. A suction valve member has first passages and a first projection portion that guides, to the first passages, the fuel that flows from a pressure chamber at the time of valve opening. Therefore, an action force by the dynamic pressure applied to the suction valve member in the valve closing direction is reduced. An action force by the pressure of fuel that flows into pressure equalization grooves counterbalances the action force by the dynamic pressure of the suction valve member. Therefore, self-closing by the dynamic pressure can be inhibited, and the maximum output of an electromagnetic driving unit can be reduced. Fuel flows through a passage radially outside the suction valve member and the first passages. A fluid passage area is securable even when a lift amount of the suction valve member is small.
