Description

  The present invention relates to an oil supply nozzle attached to an oil supply device for supplying fuel oil to an automobile.

There are two types of oil supply nozzles: a trigger type that includes a main body portion, a cylinder tip portion, and a grip portion, and has an inflow port on the side surface of the main body portion, and a lever type that has an inflow port at the rear end of the grip portion.
The trigger type oil supply nozzle is generally made of aluminum for the main body and the tip of the cylinder, and the grip part is generally made of resin. The lever type oil supply nozzle is made of aluminum for the main body, the tip of the cylinder, and the grip part. It is common.

However, since aluminum is a relatively soft metal, if the oil supply nozzle falls and hits the ground strongly, the tube tip portion may be deformed and safe oil supply may not be possible. In particular, in the case of self-service where the customer himself refuels, there is a high possibility of dropping the refueling nozzle because of inexperience.
In the case of self-service, there is a risk that a customer who is refueling may start refueling without neutralizing static electricity charged to himself / herself, and there is a risk of fire due to static electricity.
Furthermore, since the grip portion is touched by a person, there is a problem in terms of hygiene. In particular, customers with high cleanliness tend to dislike gripping the fueling nozzle, which hinders the spread of self-service.

As a form of refueling, there are a self-service refueling form in which the customer himself refuels, and an attendant refueling form in which the workers at the filling station refuel.
In the self-service lubrication mode, refueling can be performed only by continuing to pull the valve opening lever of the fuel nozzle, and safety of refueling work by unfamiliar customers is ensured.
In the attendant refueling mode, the valve opening lever of the refueling nozzle is locked so that an operator can perform service work for the customer during refueling.

  Here, in the so-called “double-decker” refueling station, it is an attendant refueling form in the daytime but a self-service refueling form in which the customer refuels at night. In addition, in the “double-deck” refueling station, considering the self-service refueling mode, a refueling nozzle that cannot be refueled without pulling the valve opening lever is used. There is an inconvenience that the service work to the customer cannot be performed during refueling when the mode is changed.

As another prior art, there is a fueling nozzle configured to discharge gasoline vapor from a fueling port of an automobile or the like to a safe place (Patent Document 1).
However, the related art is intended to prevent the occurrence of an accident caused by gasoline vapor discharged from a fuel filler port of an automobile or the like, and does not contribute to solving the above-described problems.

The tube tip 3 is an aluminum pipe and is relatively soft and conductive. The tube tip 3 is connected to the outlet at the tip of the main body 2 and is provided with a flange 9 at the rear end that prevents oil splashing from the fuel filler opening of the automobile during refueling.

In FIG. 2, the opening 12 of the liquid level detection tube 11 extending from the automatic closing mechanism provided in the main body 2 is located at L1, about 15 mm from the tip of the tube tip 3. A relatively hard stainless steel reinforcing ring 13 is provided inside the tip of the tube tip 3. The reinforcing ring 13 has an inner diameter L2 of about 15 mm, a length L3 of about 11 mm, and is provided to recede from the tip of the tube tip 3 by about L4, about 0.5 mm.
The grip portion 4 is made of resin and is insulative, and is provided at the rear end of the main end portion 2.
Between the grip part 4 and the main body part 2, a guard 14 that protects the valve opening lever 7 and a locking part 15 that is locked to a nozzle hook described later are provided. The guard 14 and the locking portion 15 are also made of resin.

In FIG. 3, a stainless steel conductive member 16 is provided on the surface of the grip portion 4, and the conductive member 16 is electrically connected to the main body 2 by a bolt 17 made of stainless steel.
The grip portion 4 is provided with a cover 18 made of conductive resin or conductive rubber. The static electricity charged on the human body is the cover 18, the conductive member 16, the bolt 17, the main body portion 2, the ground wire 8, and the oil supply. It escapes from the earth through the device.

As shown in FIG. 4, the cover 18 is a bowl shape formed in accordance with the shape of the grip portion 4, and is detachably attached to the grip portion 4.
If the shape of the cover 18 is maintained, it is only necessary to cover the cover 18 with the grip portion 4. If the shape of the cover 18 cannot be maintained, the cover 18 is covered with the grip portion 4. Then, it may be fixed to the grip portion 4 with a string or tape.
The cover 18 is subjected to antibacterial treatment, and is configured to ensure the sanitary safety of the oiler.

As shown in FIG. 5, the fueling nozzle 1 of the present invention is provided in a fueling device 21 for use.
The oil supply mechanism such as the pump 22 and the flow meter 23 of the oil supply device 21 is accommodated in the lower case 24, and control devices such as the operation panel 25 and the oil supply amount indicator 26 for inputting the oil supply data are accommodated in the upper case 27. The oil supply pipe 28 connected to the flow meter 23 is disposed in the top case 29, and the oil supply pipe 28 is connected to the oil supply hose 6.
The oil supply nozzle 1 is hung on a nozzle hook 30 provided in the oil supply device 21, and a static elimination pad 31 is provided in the vicinity of the nozzle hook 30. The charge removal pad 31 is grounded 32 via the oil supply device 21.

Next, an oil supply operation by the oil supply device 21 provided with the oil supply nozzle 1 of the present invention will be described.
In order to supply oil to the vehicle, desired oil supply data is input by operating the operation panel 25, and the static electricity charged to the fuel supplier by touching the charge removal pad 31 is released from the ground 32 via the oil supply device 21.
And the grip part 4 of the oil supply nozzle 1 is grasped and removed from the nozzle hook 30, the cylinder tip part 3 of the oil supply nozzle 1 is inserted into the oil supply port of the automobile, and the valve opening lever 7 is pulled to supply oil.

  The grip portion 4 of the fueling nozzle 1 is provided with a conductive cover 18, and the cover 18 is electrically connected to the ground 32 via the conductive member 16, the bolt 17, the main body 2, the ground wire 8, and the fueling device 21. It is connected. Thus, since the cover 18 is electrically connected to the ground 32, the static electricity charged to the oiler during refueling can be removed, and even if refueling is started without touching the charge removal pad 31, the charge is removed. You can refuel safely.

After refueling the desired amount, the valve opening lever 7 is returned to close the main valve, the refueling nozzle 1 is pulled out from the refueling port, hung on the nozzle hanger 30, and the amount is adjusted based on the numerical value displayed on the refueling amount indicator 26. Finish the work.
If the tank is full before the desired amount of fuel is supplied and the opening 12 of the liquid detection tube 11 is closed with oil, the main valve is closed by the automatic valve closing mechanism provided in the main body 2 and the fuel supply ends. .

Even when the oil supply nozzle 1 is accidentally dropped during the oil supply operation and the tube tip 3 is strongly hit against the ground (when an impact due to dropping is applied), the reinforcing ring 13 is provided at the tip of the tube tip 3. Since it is provided, the tube tip 3 is not deformed.
Thus, since the cylinder tip part 3 is not deformed by the reinforcing ring 13, the liquid level detection tube 11 and the opening 12 are not damaged, and the safety of the oil supply operation can be ensured.
Similarly, the automatic valve closing performance due to the change in the discharge performance caused by the deformation is not deteriorated.

Here, since the relatively hard stainless steel reinforcing ring 13 is disposed by being retracted from the tip of the relatively soft aluminum tube tip 3, the tube tip 3 is mistaken for the ground or automobile during the refueling operation. Even if it hits a hard part such as an oil filler opening, there will be no sparks and the safety of refueling work can be ensured.
Further, even if the cylinder tip portion 3 of the oil supply nozzle 1 accidentally hits the automobile or the oil supply device 21 during the oil supply operation, a relatively soft aluminum part in the cylinder tip portion 3 hits, so that the automobile or the oil supply device 21 is damaged. Less is enough.

When the cover 18 of the grip 4 is soiled or damaged by using the oil supply nozzle according to the illustrated embodiment for a long period of time, the cover is replaced with a new cover 18 and used.
Since the cover 18 is detachably attached to the grip portion 4, the replacement work is easy.
By exchanging the cover 18 in this manner, safety in terms of hygiene can be ensured, and the refueling operation can be performed without the customer feeling disgusted.

  As described above, since the refueling nozzle 1 of the present invention is provided with various safety measures, it is attached to a refueling device installed in a self-service refueling station where the customer himself refuels for safe and suitable refueling. Can work.

  Next, a description will be given of a case where an attendant oil supply mode for supplying oil by a worker at a gas station is performed using the oil supply nozzle 1 of the present invention (for example, in the case of “double-decker” described below).

Here, in the attendant oil supply mode, a so-called “latch mechanism” is provided in the oil supply nozzle 1 so that the oil supply operation can be continued even if the valve opening lever 7 is released. The worker performs service work such as wiping the window of the customer's car during refueling.
However, in the daytime, it is an attendant refueling form, but in the so-called “double-decker” refueling station where the customer himself refuels at night, in order to improve safety during self-service, The “latch mechanism” cannot be provided in the fueling nozzle 1.
Therefore, in the illustrated fueling nozzle 1, in order to continue the fueling even if the hand is released from the fueling nozzle 1, the valve opening lever locking tool 35 held by the worker is used.

The space between the leg A and the legs B and C is a portion where the guard 14 of the valve opening lever 7 is inserted and the valve opening lever locking member 35 is fixed to the guard 14.
The leg B is a part that holds the valve opening lever 7 at a position that opens the main valve, and the leg C is a part that holds the valve opening lever 7 at a position that fully opens the main valve.

As shown in FIG. 7, in order to refuel at a small flow rate, start refueling with the valve opening lever 7 pulled slightly, and the distance between the leg A and the legs B and C of the valve opening lever locking tool 35 is increased. The guard 14 is inserted and the valve opening lever 7 is brought into contact with the leg B.
Thus, in the state where the guard 14 is sandwiched between the leg A and the legs B and C, the valve opening lever locking tool 35 is fixed to the guard 14 and the valve opening lever 7 is brought into contact with the leg B. In the state, the valve opening lever 7 is held at the small open position, and even if the hand is released from the fuel supply nozzle 1, the fuel supply at a small flow rate is continued.

In order to supply the oil at a large flow rate, start the oil supply with the valve opening lever 7 pulled largely, insert the guard 14 between the leg A and the legs B and C of the valve opening lever locking device 35, The opening lever 7 is brought into contact with the leg C.
In this way, in a state where the valve opening lever 7 is in contact with the leg C, the valve opening lever 7 is held fully open, and the oil supply at a large flow rate is continued even if the hand is released from the oil supply nozzle 1.

  Thus, the service to the customer can be improved by providing the valve opening lever locking member 35 to the worker at the gas station and adopting the attendant oil supply form as necessary.
