DETAILED DESCRIPTION OF THE INVENTION The present invention is directed to a lubrication device (t) which is particularly effective for briquette lubrication and dregs lubrication.

The refueling device F+ is roughly divided into a ground-mounted 16-type type and a high-mounted type. A refueling nozzle is connected to the tip ψ11J (lower end) of the hose that hangs down from the storage device H.

As the piping (on the back of the ceiling and on the roof) is heated, some of the oil in this piping turns into heat, and the difference between the pressure of the fish and the oil increases. It is inconvenient that the oil in the hose is discharged from the nozzle even though the oil has been completely removed. Yes, it is dangerous.

The second inconvenience or danger is to close the built-in valve of the nozzle at exactly 111 °C and stop the refueling. I can do it.

By the way, in this type of refueling device for 1 yen, the refueling nozzle used for f-staining does not have the tip of the nozzle. Some tanks are inserted into wave refueling tanks for refueling (so-called i:
The automatic closing valve automatically closes the built-in valve that opens and closes the flow path of the nozzle when the nozzle leaks (the shaving mechanism is tilted).

The most common type of automatic valve closing mechanism is the 11th one, and the DaC yaphram, which is connected through an appropriate element to the opening/closing lever of the nozzle's built-in valve, is housed within 17 yen. i! ! ! When the lees oil tank is full, it emits a negative L1.41:
