Title: Cap of fuel tank for motorcycle
Inventor: SEKIYAMA KAZUO
IPC: F02M37/00
Filed: 1988-12-27
Abstract: PURPOSE:To prevent fuel from leaking even if a motor bicycle inclines by installing a relief passage, which connects the inside of a fuel tank and outside air, to a cap main body as a system separated from a breather passage and closing the relief passage by means of a permeable resisting member. CONSTITUTION:A relief passage 14 is installed to a cap main body 6a in such a manner that this passage 14 is situated in the symmetrical position with a breather passage 13, which is provided to prevent fuel from flowing back to the outside of the tank 3, and that the passage 14 becomes a system separated from the breather passage 13. In addition, a permeable resisting member 19 made of felt, ceramics or the like is placed in this relief passage 14. With this contrivance, even if the inner pressure of the tank rises when motor bicycle falls down to deform the tank 3, the inner pressure of the tank can be relieved, owing to the relief passage 14. In addition, even if the relief passage 14 is submerged beneath the oil when the bicycle inclines, the fuel meets with the viscous resistance of the resisting member 19 and consequently the fuel scarcely leaks to the outside only if the rider pulls up the bicycle at once.
