Abstract

PURPOSE: A fuel supply stopping device is provided to block a fuel pipe once an air bag is deployed. CONSTITUTION: A fuel supply stopping device(1) comprises an air bag electronic control device(4) deploying an air bag through a collision sensor(2) and a velocity sensor(3), and a solenoid valve member(6) blocking a fuel pipe(5). The solenoid valve member consists of a solenoid valve(9) installed in a net plate(8) of the fuel pipe, and a stopping plate(12) stuck to a port seat(11) of a stopping port(10) by interlocking with the solenoid valve. The air bag electronic control device pulls the stopping plate to close the stopping port with the solenoid valve in case of a collision. The stopping port is placed in the fuel pipe near a delivery pipe to stop fuel flowing. Thus, a fire caused by fuel leakage is prevented in case of a collision.
