Abstract

An LPG bombe valve apparatus includes a valve body, a check valve, a cam, a cam rod and a converting mechanism. More specifically, the valve body is disposed in an LPG bombe and having a fuel channel therein for discharging fuel supplied from an LPG line to the LPG bombe. The check valve is disposed in the fuel channel, with one end supported by an elastic member to be pressed to close the fuel channel. The cam is disposed within the check valve, and the cam rod connects the cam with the check valve and controls opening / closing of the check valve in accordance with rotation of the cam. A converting mechanism has both ends connected to the cam and a float of the LPG bombe converting vertical motion of the float into rotational motion of the cam.

Description

[0001] Related Application Cross Reference [0002] This application claims the benefit of Korean Patent Application No. 10-2012-0153736 filed on December 26, 2012, the entire contents of which are hereby incorporated by reference. technical field [0003] The present invention relates to a fuel tank of a vehicle using liquefied petroleum gas (LPG) fuel, and more particularly, to an LPG tank valve device that keeps the pressure of the LPG tank constant at all times. Background technique [0004] In an LPG vehicle using LPG (Liquefied Petroleum Gas) as fuel in the related art, the LPG is vaporized and supplied to an engine. However, LPI (Liquefied Petroleum Injection), which injects liquid LPG fuel at high pressure directly through the injector, is sometimes used to improve starting in winter. In this case, when the LPG fuel is refilled while there is a sudden change in the composition of the fuel or in the temperature or pressure inside the LPG tank, the fuel pump may lose ...
