ABSTRACT:
The present invention relates to a device for preventing gush of fuel oil from the filler neck during the oil supplying. The oil dispersing device according to the invention is mounted at the inner end of the filler neck located in the fuel tank. The fuel oil dispersing device 10 includes a conical hollow dispersing plate 11 having a through hole formed at the top portion thereof, and a cylindrical extension rod 12 having a thread 13 formed at one end, and an insert 14 mounted at the other end. The dispersing plate 11 is mounted on the thread portion of the extension rod by means of a pair of nuts at both sides of the through hole. An insert 14 is provided for securely mounting the other end of the extension rod and for securing it within the lower end portion of filler neck. The end portion of filler neck 20 has a stepped section, and the insert is formed a lot of passages therethrough. As the injected oil through the filler neck is uniformly directed to the fuel tank and disperses to all direction in the tank, no specific oil flow in the fuel tank is occurred, which prevents injected oil from flowing backward to the filler neck.
