Description

Airtight cap for lubricator {Airtight cap for a lubricator}

The present invention relates to a gas tanker, and more particularly, to reduce the loss of fuel by reducing the gaseous fuel generated when refueling a vehicle at a gas station, and moreover, to prevent the gaseous fuel containing harmful components from entering the atmosphere. And it relates to a closed cap for the lubricator to prevent the health of gas stations.

In general, a gas tanker installed at a gas station is a device for sucking oil from an oil storage tank buried underground to supply oil to a vehicle through a hose, which includes an oil pump main body including an oil suction and various related mechanical devices therein. It is composed of a fuel nozzle connected to the main body and the hose so that the oil sucked by the mechanical operation inside the main body to supply the fuel tank of the vehicle.

In Figure 1, the lubricator 1 is provided with a lubrication nozzle 11 to protrude in a spout form from the body 10 formed so that the gas source can be easily grabbed by hand, flowed into the body 10 through the hose 12 It is configured to discharge the oil to the outside. A lever 13 is installed at the lower end of the body 10 to perform opening and closing flow paths by pulling and releasing a gas station. In addition, the lubricator 1 is provided with an automatic operation means for stopping the lubricating stroke at the completion of lubrication while allowing the lubricating stroke to be made continuously without refueling and holding the lever 13 at the time of refueling.

As such, the fuel is injected into the fuel inlet of the vehicle through the lubricator 1. However, since the fuel inlet of most vehicles is made larger than the lubricator 1, the vaporized fuel generated when lubricating the vehicle flows into the gap formed between the fuel inlet and the lubricator, causing loss of fuel. As the fuel gas vaporized from the vehicle fuel flows into the atmosphere as it is, the wastewater that causes air pollution was followed.

In addition, when the fueling station sets the fueling amount of the customer and the fueling machine 1 is inserted into the fuel inlet and is simultaneously refueling in another car due to lack of work, the fueling machine 1 exits from the fuel inlet and the fuel Since it is sprayed, there was a problem of not only wasting fuel and environmental pollution, but also causing a large fire by static electricity.

In addition, fuels such as gasoline and diesel used in the internal combustion engines of vehicles have the best performance through ideal combustion in these engines to maximize engine efficiency while minimizing the emission of harmful emissions. B. A certain amount of additives is mixed with the basic oil produced by the cracking process, etc. There are some basic differences in gasoline and diesel oil produced as fuel of the internal combustion engine at each refinery, but there are some basic requirements to meet the specifications. Fuel additives are included.

Accordingly, in the fuel fuel, sulfur, benzene, sulfur of gasoline, and some additives in use for the purpose of improving the performance of vehicle fuel pose a problem of human health. Due to the harmful components and additives contained in fuel, gasoline sources are exposed to gaseous fuel gas from the gap between the fuel inlet and the gas tank of the vehicle as they are causing health problems such as headache, eye irritation, and nausea. On the other hand, some additives have been found to contain carcinogenic substances that can cause cancer, resulting in a deadly health problem.

Accordingly, the present invention is to fundamentally solve the conventional problems as described above, and in general, reducing the loss of fuel by reducing the vaporized fuel generated when the vehicle is refueled at the gas station, and furthermore, the vaporized fuel containing harmful components The purpose is to provide an airtight cap for the lubricator to prevent environmental pollution and the health of petrol stations by preventing the flow into.
