Abstract: An electromagnetic body has a movable core reciprocatably movable within a movable core chamber. The movable core has through holes and a fitting hole that pass through the movable core in a direction of movement of the movable core. A stator core facing the movable core defines the movable core chamber together with the electromagnetic body. A valve stem is fixed into the fitting hole and has a fluid chamber recessed from a first end surface facing the stator core. Air bubbles generated in a gap can be guided into the fluid chamber and collapse by flow of the fuel flowing into the fluid chamber from the through holes through the gap.

Abstract: A valve seat member, which partitions between a supply passage and a pressurizing chamber, includes an inner flow path, which communicates between the supply passage and the pressurizing chamber, and an outer flow path, which is placed on a radially outer side of the inner flow path. An inner valve is seatable against an inner valve seat formed in an opening of the inner flow path. An outer valve is contactable with an end surface of the inner valve, which is opposite from the inner valve seat. The outer valve is seatable against an outer valve seat, which is formed in an opening of the outer flow path.
