Description

[Detailed Description of the Invention] The present invention relates to a fuel tank device mainly applied to family motorcycles.

Conventionally, this type of device has a liquid level system consisting of a vertically swingable arm extending near the bottom of the inlet, and a float at the tip of the tank body, which has an inlet on the upper surface and an outlet on the lower surface. Types with a meter are known, but in this type, when a fuel injection gun is inserted through the injection port,
This causes inconveniences such as interference with the float, damaging it, or further deforming the arm, which tends to cause poor pointing.

The purpose of the present invention is to obtain a device free of such inconveniences. In a type equipped with a liquid level gauge 6 consisting of an extending vertically swingable arm 4 and a float 5 at the tip thereof, a cylinder 7 for regulating the liquid level is protruded downward from the bottom of the inlet 1. At the same time, a guard member 8 is provided horizontally on the lower side of the cylindrical body 7 with both ends fixed thereto.

The device of the present invention is applied to a family bike, for example, as shown in the first drawing, where 9 is a vehicle body, 10 and 10 are front and rear wheels, and 11 is an intermediate engine. 3, and a seat 12 for a passenger is provided on the upper surface thereof.

In the drawing, 13 is a mounting bracket extending from the main body 3;
Reference numeral 14 indicates a removable cap on the upper surface of the injection port 1, and reference numeral 15 indicates a liquid level sensor at the root of the arm 4.

The cylindrical body 7 described above has a through hole 16 at its bottom to allow a fuel injection gun to pass therethrough, and a vent hole 17 that opens laterally at its top. Since the through hole 16 is narrowed and opened as described above, the above-mentioned guard member 8 below the through hole 16 needs to be relatively narrow, and thus, there is little blowback that occurs when fuel is injected.

Further, the member 8 is cut out from a longitudinal piece as shown in the figure, overlaps both side surfaces of the cylinder body 6 at bent portions at both ends, and is fixed thereto by welding or other means. It is formed into a chevron shape, thus preventing the injected fuel from hitting it and blowing back.

To explain its operation, when the gun is inserted from the injection port 1 when injecting fuel, the tip of the gun hits the guard member 8 and there is no further insertion. The arm 4 is prevented from interfering with it.

In this way, according to the present invention, the guard member 8 is provided on the lower side of the injection port 1, and the fuel injection gun inserted through this guard member is prevented from interfering with the float 5 or arm 4 located below. In addition, the member 8 is fixed to the lower side of the liquid level regulating cylinder I extending downward from the injection port 1. By preparing and fixing it to the cylindrical body 7 in advance, it has the effect of making the installation simple and easy.
