Abstract

A gas leakage preventing unit of an LPG(Liquefied Petroleum Gas) fuel injecting device is provided to prevent LPG fuel gas from leaking out while injecting the fuel gas into a vehicle. A gas leakage preventing unit of an LPG fuel injecting device comprises a support member(10) supporting a spring(20); a valve(40) elevated and operated by the elastic force of the spring; and a protrusion member(30) mounted at the outer side of the support member to guide settling of the spring. The spring operates the valve to an original position by the elastic force after injecting gas into a vehicle. The protrusion member is formed on the support member to limit a movement width of the spring so as to prevent the spring from being defectively attached on the upper end of the support member due to sliding.

상기 돌출부재(30)는 스프링(20)의 작동시 일측으로 치우침을 방지하여, 스프링(20)으로 작동되는 밸브(40)의 일측 치우침 현상을 방지한다. 이에따라, 스프링(20)의 작동으로 작동되는 밸브(50)는 도 3에 도시된 바와 같은 일측 치우침 현상이 발생되지 않아 LPG 연료 가스의 주입시 가스 누출의 발생을 방지하도록 한다.The protruding member 30 prevents the bias toward one side during the operation of the spring 20, to prevent the bias phenomenon of one side of the valve 40 to be operated by the spring (20). Accordingly, the valve 50, which is operated by the operation of the spring 20, does not generate a side bias phenomenon as shown in FIG. 3 so as to prevent the occurrence of gas leakage during the injection of the LPG fuel gas.

상기와 같은 본 발명에 따른 LPG 연료 주입장치의 가스누출 방지장치는 다음과 같은 효과를 갖는다.The gas leakage preventing device of the LPG fuel injection device according to the present invention as described above has the following effects.

서포트부재에 구비된 돌출부재를 통하여 스프링의 일측 치우침을 방지하여,스프링 구동되는 밸브의 치우침에 따른 LPG 연료 가스의 주입에 따른 LPG 연료 가스의 누출을 방지함으로써 소비자의 차량 신뢰성을 향상시킨다.By preventing the bias of one side of the spring through the protruding member provided in the support member, the vehicle reliability of the consumer is improved by preventing the leakage of the LPG fuel gas due to the injection of the LPG fuel gas due to the bias of the spring driven valve.
