Abstract: A fuel pump module includes a fuel pump, a housing, a filter, a bracket, a lid, a fuel passage, and a pressure regulating valve. The fuel pump supplies a fuel in a fuel tank that defines an opening to an outside of the fuel tank. The housing has a cylindrical shape and supports the fuel pump. The bracket connects the filter to the housing. The lid covers the opening and defines a discharge port through which the fuel is supplied to the outside. The fuel passage connects the fuel pump to the discharge port. The pressure regulating valve has a gravity center inside a space defined by a first virtual cylindrical surface including the housing. A minimum circumscribed circle of both the housing and the filter is smaller than the opening.

Abstract: A fuel injection valve includes a valve body, a fixed core, a movable core, a spring, and a cup. The spring is elastically deformed according to valve opening operation of the valve body, and exerts a valve closing elastic force for closing the valve body. The cup contacts a valve closing contact surface of the valve body, and transmits the valve closing elastic force to the valve body. At a start of predetermined-distance movement of the movable core together with the cup, the cup is in contact with the valve closing contact surface, and the valve body or the cup has a supply flow channel through which fuel is supplied to the valve body closing contact surface which is in a state contacting the cup.
