DEVICE FOR AUTOMATICALLY REGULATING NATURAL PRESSURE OF LIQUID FUEL AND CARBURETOR OF NATURAL PRESSURE REGULATING TYPE COMPRISING THE SAME

摘要

The present invention relates to a natural pressure-controlled vaporizing device for vaporizing a liquid fuel such as petroleum and mixing it with air to supply it as fuel, and a natural pressure-regulating device for liquid fuel applied thereto, wherein the natural-pressure-controlled vaporizer comprises a fuel tank and ; A level control tank in which petroleum fuel in the fuel tank flows through a fuel inlet pipe, a level switch that is switched on when the petroleum fuel in the water level control tank reaches an optimum vaporization level, and the level A liquid fuel natural pressure regulating device including a drive valve that is operated in the case of switching on of the switch to close the fuel inlet pipe; The water level control tank is arranged in parallel and a vaporizer outlet is formed at the top, and petroleum fuel in the water level control tank flows through a fuel supply pipe to reach the optimum level of vaporization by reaching the same level as the petroleum fuel in the water level control tank. It includes; a vaporizer tank, and a vaporizer including a heater that heats and vaporizes petroleum fuel stored in the vaporizer tank to be discharged to the vaporizer outlet. According to this, it is possible to achieve a fuel-saving effect while having a relatively simple structure since it is possible to naturally adjust the optimum conditions for the vaporization of the liquid fuel by always supplying the liquid fuel at a constant level to the vaporizer.
