Abstract: PURPOSE: An omnidirectional fluid valve and a fuel feeding apparatus applied with the same are provided to always secure a fuel discharge path using a gravitational weight, thereby always stably feeding fuel even in the air in which the posture of a fuel tank is varied. CONSTITUTION: An omnidirectional fluid valve (1) has a valve cylinder (10). The valve cylinder generates a restoring force so that a gravitational center thereof coincides with a gravitational direction through inertia due to the weight thereof in spite of the posture variation of a fuel tank (100). The restoring force always opens a fuel inlet path through which fuel flows inside the space of the valve cylinder. The fuel is fed from the tank to a fuel pipe. The fuel flowing inside the space through the fuel inlet path is re-discharged. [Reference numerals] (AA) Inlet; (BB) Outlet; (CC) Fuel; (DD) Fuel discharge path
