摘要： A fluid pressure regulating device is i) provided with a pressure regulating member that forms a pressure regulating chamber inside a housing having introduction side and discharge side fuel passages, and communicates these passages according to introduced fuel pressure, and ii) is able to regulate the fuel pressure introduced into a fuel passage to a set pressure. The housing is provided with outer and inner annular valve seat portions that separate the fuel passages inside the pressure regulating chamber, and form another fuel passage inside the pressure regulating chamber. Different clearances are set between the pressure regulating member, and the outer annular valve seat portion and the inner annular valve seat portion, such that when the pressure regulating member abuts against one of the valve seat portions, a small gap is formed between the other valve seat portion and the pressure regulating member.

摘要： A fuel supply device comprises a fuel pump, a set plate, a control circuit, and an electrical wiring member. The fuel pump is disposed within a fuel tank. The set plate closes an opening of the fuel tank. The set plate comprises a controller chamber isolated from the fuel tank. The control circuit is disposed within the controller chamber. The control circuit controls the fuel pump. The electrical wiring member connects the control circuit and the fuel pump. The electrical wiring member is arranged from an interior of the controller chamber to an interior of the fuel pump and is passed through the set plate. A part of the electrical wiring member is exposed to the atmosphere. Furthermore, the exposed part is disposed within a range from the interior of the fuel tank to the interior of the controller chamber.
