Abstract
PURPOSE: To prevent fuel leakage near carburator, by installing relief valve to open when the pressure in the fuel tank is more than periscribed value comparing with atmospheric pressure, to the fuel tank cap.
CONSTITUTION: Relief valve body 5 has hollow body 5a fixed valve material 5b inside of it, energized downwards for the valve seat 6 by spring 10, vent hole 14 is formed at the center of relief valve material 5b, air vent-use valve material 16 having projection 15 correspond to vent hole 14 is arranged inside of relief valve body 5a. Fuel tank is deformed due to upset of vehicle body, when the inner prssure is raised abnormally due to reducing volume, relief valve body 5 is pushed up oppos ing 10 force, valve body 5b is off from ring projection 6a of valve seat 6. In result, the pressure in the tank is escaped out through the groove 12 from vent hole 13 and vent hole 11.
