摘要： A fuel supply device may include a housing including a housing body and a lid. The housing body may form a fuel storage tank. A fuel pump, a regulator, and a fuel storage amount adjusting unit may be disposed in the housing. The lid may have an excess fuel discharge path through which excess fuel flowing down from the regulator is fed to an inner wall side of the housing body. The housing body may have an upward fuel receiving surface that receives the excess fuel discharged at a lower position on an end side of the excess fuel discharge path. The fuel receiving surface may be structured and arranged such that the excess fuel discharged through the excess fuel discharge path is temporarily received by the fuel receiving surface and then returned to the fuel storage tank along an inner wall surface of the housing body.

摘要： A fuel supply system includes a housing including a housing body in which a fuel storage tank serving as a reservoir tank as well and a lid covering an opening of the housing body in an air-tight manner. The housing includes a fuel pump, a regulator configured to regulate a pressure of the fuel to return excess fuel to the fuel storage tank, a regulator holding member supporting the regulator, and a fuel storage volume adjusting unit that maintains the liquid surface level of the stored fuel at a fixed level. The fuel supply system supplies fuel at a predetermined pressure from a fuel discharging pipe of the lid to the engine. The regulator holding member is formed in such a manner in a planar view as to fill most of interspace in the opening of the housing body to close the upper portion of the fuel storage tank.

摘要： A fuel supply device may include a housing, a fuel pump, a regulator, and an atmosphere communication passage. The housing may include a housing main body in which a fuel storage tank is formed and a lid body that covers an opening part of the housing main body. The fuel pump may feed a fuel that is stored. The regulator may return a surplus fuel to the fuel storage tank while regulating a pressure of the fuel. The atmosphere communication passage may penetrate through from a bottom surface side to an upper surface side of the lid body to communicate an upper space of the fuel storage tank with an outside. A center line of an inlet-passage vertically disposed and a center line of an outlet-side passage vertically disposed may be shifted from each other by a predetermined distance in a horizontal direction.

摘要： In a fuel supply apparatus, an injector and a throttle valve are provided in a throttle body, and the fuel supply apparatus is disposed between an intake manifold and an air cleaner of a two-cylinder general-purpose engine and supplies fuel adjusted to a predetermined air-fuel ratio to both cylinders of the two-cylinder general-purpose engine by one injector. The throttle body includes a fuel supply unit having the injector and an air amount control unit having the throttle valve. The fuel supply unit and the air amount control unit are formed of separate components that can be separated or joined.

摘要： A seal is fit between a cylindrical connector support which is protruded on an upper end face of a cylindrical barrel part of an electrically-powered high pressure pump embedded in a housing and from which a power connector is exposed and an inner peripheral surface of a hollow part formed in a top face of a lid body such that the seal is flush with a top face of the hollow part. A flange having an outer shape which is the same as an inner shape of the hollow part is protrudingly provided at a predetermined height position on a circumference of the connector support such that a lower surface of the flange is disposed flush with a top face of the hollow part.
