Abstract

PURPOSE: A vaporizer for an LPG automobile is provided to with a stopping bracket to maintain a drain lever in its accurate closed position after removing tar, thereby preventing backfire or turning of an ignition. CONSTITUTION: In a vaporizer for LPG vehicle, an LPG is vaporized to be supplied to a cylinder of an engine. A drain lever(14) is provided to operate a drain valve(12) discharging tar. A stopping bracket(20) is installed adjacent to the drain lever(14) vertically with the drain lever(14). The stopping bracket(14) has a connection bolt(22) to prevent the drain lever(14) from rotating when the drain lever(14) is positioned in its ordinary closed position.

Description

LPV Car Vaporizer {VAPORIZER FOR A LPG VEHICLE}

The present invention relates to an LPG vehicle vaporizer, and more particularly, to an LPG vehicle vaporizer in which a stopping bracket is installed on the vaporizer of the LPG vehicle so that the drain lever can be kept closed at the correct position after tar removal.

Although automobiles are classified into passenger cars, buses, and trucks according to their type, the same type of fuel is used for gasoline vehicles using gasoline as a fuel, diesel vehicles using diesel as fuel, and LPG (Liquefied Petroleum Gas) as fuel. Also known as LPG vehicles.

LPG vehicles are equipped with a vaporizer to supply fuel by evaporating the fuel in order to smoothly burn the mixer in the cylinder of the engine. Thus, in LPG vehicles, the use of vaporizers is essential, but impurities and tar contained in the LPG are attached to the fuel system together with the less volatile foreign matter remaining in the fuel without being volatilized in the fuel. As such, when foreign matter and tar are attached to the fuel system, various problems such as starting off due to a fuel supply failure of the fuel system occur.

Therefore, tar needs to be periodically removed from the vaporizer, and a drain lever as shown in FIG. 1 is used for this purpose. 1 is a front view showing the configuration of a conventional vaporizer.

The lower end of the vaporizer 10 for evaporating the LPG is provided with a drain valve 12 for discharging the tar, the drain valve 12 is a drain lever 14 for manually opening the valve to discharge the tar Is installed. Therefore, the driver usually discharges tar by rotating the drain lever at every 5000 km of travel distance.

However, in the conventional LPG vehicle vaporizer, if the vehicle driver does not return the drain lever to the closed position after discharging the tar by turning the drain lever, there is a possibility that the outside air flows in, and thus, the start-up and backfire are caused. or back fire.

In addition, the tar outlet is typically located at the bottom of the vaporizer to allow debris and tar to flow down by gravity when the valve is opened, which is why the exact closing position of the drain lever in vehicles with complex engine compartments It is very difficult to check with the naked eye.

The present invention for solving this problem is to remove the tar by using the tar discharge drain lever to remove the tar and then return the drain lever to the closed position correctly, so that the closed state can be maintained accurately by the closing failure An object of the present invention is to provide a vaporizer vaporizer for an LPG vehicle that can prevent idle assistance, starting off, and white wire.

In the LPG vehicle vaporizer of the present invention for achieving the above object is to supply liquefied gas to the cylinder of the engine by evaporating liquefied gas, LPG vehicle vaporizer is provided with a drain lever for discharging tar by operating the drain valve, In the area adjacent to the drain lever is characterized in that the stopping bracket for preventing the rotation of the drain lever when the drain lever is located in the normal closing position by the fastening bolt is installed in parallel with the drain lever.

Hereinafter, an LPG vehicle vaporizer according to a preferred embodiment of the present invention will be described in detail with reference to the accompanying FIG. 2, and the same parts as in the conventional structure are denoted by the same reference numerals.

2 is a front view showing the configuration of the vaporizer according to the present invention. As described above, the vaporizer 10, which vaporizes the liquefied gas in the LPG vehicle and supplies the gas into the combustion chamber of the engine, is provided with a drain valve 12 for removing tar contained in foreign substances and fuel. 12, the drain lever 14 for valve opening and closing is provided so that rotation is possible.

In the vaporizer of this configuration, in order to maintain the drain lever 14 in the correct closed position after removal of the tar, in the preferred embodiment of the present invention to prevent the drain lever 14 from rotating more than a certain degree Stopping bracket 20 is installed.

The stopping bracket 20 is installed in parallel with the drain lever 14 so as to stop at the position where the drain lever 14 is correctly closed by the fastening bolt 22. Instead of the fastening bolt 22 is provided separately, the fastening bolt for the housing cover of the vaporizer 10 may be used in combination.

In the preferred embodiment of the present invention described so far, the drain lever is exemplified in a structure having a stopping bracket so that it can no longer be rotated after returning to the correct closed position, but a person skilled in the art will appreciate It will be understood that various modifications, changes, additions, and the like are possible without departing from the spirit of the invention. For example, a stoppering protrusion may be integrally formed in the housing of the vaporizer to prevent further rotation of the drain lever, and if necessary, the drain lever may be operated by a solenoid or the like to return to the correct position after tar removal. .

According to the present invention described above, the stopper bracket is installed on the vaporizer of the LPG vehicle so that the drain lever remains closed at the correct position after the tar is removed, thereby preventing idle assistance, starting off phenomenon and white wire due to the closing failure. There is an advantage to this.
