Embodiment Construction

[0025] Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

[0026] This embodiment is a fuel tank 1 installed on a vehicle such as a truck powered by an engine driven by liquefied gas fuel. Here, as the liquefied gas fuel, for example, LPG (liquefied petroleum gas) fuel or DME (dimethyl ether) fuel is used.

[0027] Fuel tank 1, such as figure 1 As shown, the tank main body 2 is arranged on the tank main body 2 as a valve device 5 for opening and closing the valve as a liquefied gas fuel filling port, and is arranged on the tank main body 2 for measuring the liquid level position of the liquefied gas fuel. The liquid level gauge 6 is configured with an overfill prevention device 7 installed inside the tank body 2 and connected to the valve device 5 to prevent the filling of liquefied gas fuel from exceeding a specified amount. Here, the liquid level gauge 6 and the overfill prevention device 7 are configured to inclu...

Abstract

The invention provides a buoy capable of playing an excellent part in the inner pressure of a flue tank. The buoy is formed by welding a cup body (22) and a cover body, a cup side rib (34) arranged in the cup body (22) and an annular cover side rib (47) arranged in the cover body is spaced under the state that external forces are not applied on the cover body, and are contacted via the cover body (23) under the state that the external forces are applied on the cover body. According to the structure, the bending degree of the cover body when external forces are applied on the cover body can be restrained, and the stresses applied on the cover body (23) or a welding part can be reduced, so that the strength of the cover body (23) or a welding part can be improved. Moreover, the cup body (22) and the cover body (23) are not contacted when being welded, so that the cup body (22) and the cover body (23) can be positioned accurately and the welding quality can be improved, and accordingly, the strength of the welding part can be improved.

Description

technical field [0001] The present invention relates to a buoy arranged in a fuel tank storing fuel such as gas or liquid, and floating with the liquid level of the fuel. Background technique [0002] For example, a fuel tank storing liquefied petroleum gas (hereinafter referred to as LPG) fuel or liquefied gas fuel such as dimethyl ether (hereinafter referred to as DME) is equipped with a liquid level gauge or an overfill prevention device. The liquid level gauge or the overfill prevention device generally includes a float that floats with the liquid level of the fuel stored in the tank. [0003] As such a buoy, the structure of patent document 1 is proposed, for example. The buoy of this conventional structure is a hollow body in which a lid body closing the opening is welded to a cylindrical cup body with one end open and the other end closed, and ribs are formed inside the cup body. In this buoy, the strength of the cup is improved by forming ribs. [0004] [Patent Do...
