Embodiment Construction

[0026] Hereinafter, embodiments of the present invention will be described with reference to the drawings. Figure 4 It is a side view of an off-road two-wheeled vehicle equipped with a fuel supply device according to an embodiment of the present invention. In this figure, a motorcycle 1 has a front fork tube 10 located in front of the vehicle body, a main frame 11 extending rearward and downward from the front fork tube 10, a front end combined with the lower end of the main frame 11 and extending rearward. The vehicle body girder that the lower vehicle frame 12 constitutes. The rear portion of the lower frame 12 is raised again and forms the rear frame 13 .

[0027] A handlebar 2 is provided on the top of the front fork tube 10 . The front wheel 3 is supported by a front fork 14 extending downward from the front fork tube 10 . The engine 4 is mounted between the main frame 11 and the lower frame 12 . An intake pipe 5 and an exhaust pipe 6 are connected to the engine 4, a...

Abstract

A fuel supply device for a vehicle. The fuel supply device (20) is suitable for being installed in a fuel tank of a two-wheeled vehicle such as an off-road vehicle. A cylindrical and elongated casing (25) extends downward from a bottom plate (41) fixed to a plate (182) fitted on an upper surface (181) of a fuel tank (18). A suction pipe (23) having a filter (22) is connected to the front end of the motor pump (24) in which the motor pump (24) is arranged at the bottom of the casing (25). On the discharge channel (30) above the motor pump (24), a pressure regulating valve (32) and a check valve (38) capable of being accommodated in the outer shape of the fuel pump (24) are arranged. Such a fuel supply device can be easily installed in a fuel tank having a narrow width and a complex shape.

Description

technical field [0001] The present invention relates to a fuel supply device for a vehicle, and more particularly to a fuel supply device for a vehicle suitable for being arranged in a small and narrow fuel tank. Background technique [0002] On the fuel pump main body, a fuel supply device including a regulator, a check valve, and the like is attached to the fuel tank. For example, Japanese Unexamined Patent Publication No. 11-294285 discloses a fuel supply device arranged in a fuel tank. The fuel supply device comprises a cylindrical fuel pump, a fuel filter arranged around the fuel pump, and A pressure regulating valve and a check valve arranged above the fuel pump and outside the extended line of the outer diameter of the fuel pump, and a container accommodating these components are integrally formed. [0003] In addition, JP-A-2001-3826 discloses a pump unit in which a fuel pump unit and an injection pump are assembled on a reservoir arranged in a fuel tank. [0004] ...
