Abstract

At least one choked flow passage communicates between one side of the movable member and the other side of the movable member and limits an amount of fuel, which passes from the one side of the movable member to the other side of the movable member, when the movable member is moved by an urging force of a relief spring toward a valve element. A larger amount of fuel, which is larger than the amount of fuel that is passable through the at least one choked flow passage, flows from a first return flow passage to a second return flow passage, when the movable member is moved toward the other side, which is opposite from the valve element, against the urging force of the relief spring.
