Description

fuel nozzle

[0001] The present invention relates to a fuel nozzle used to fill a fuel tank of an automobile or the like at a gas station.

[0002] Conventionally, a fuel nozzle attached to the tip of a fuel hose of a fueling device that supplies fuel to automobiles and the like at a gas station has a discharge pipe that faces upward and is hung on a nozzle hanger after refueling is completed, so fuel oil adhering to the discharge pipe can drip down and soil the nozzle body. In the case of fuel oil that is easily volatile, such as gasoline, this is not a problem because the fuel evaporates on the way to the nozzle body, but in the case of fuel oil that is less volatile, such as diesel or kerosene, the fuel oil adhering to the discharge pipe drips down and soils the nozzle body, which can then soil the hands and clothes of the next person who fills the tank, leaving room for improvement.

[0003] Therefore, in Patent Document 1, the applicant of the present invention proposed providing an oil receiving portion on the nozzle body to receive fuel oil dripping from the discharge pipe and prevent the nozzle body from becoming dirty.

[0004] International Publication No. WO2018 / 158872

[0005] Although the above proposal is effective, the seal portion of the oil receiving part is located on the outer diameter part of the end of the discharge pipe, and when attaching the oil receiving part to the nozzle body side of the discharge pipe, it is necessary to climb over the anchor spring arranged on the discharge pipe. If the seal portion of the oil receiving part is damaged in this process, the sealing performance will be deteriorated and there is a risk of fuel oil dripping.

[0006] Furthermore, depending on the amount of fuel oil adhering to the discharge pipe, the fuel oil may overflow from the oil receiver and flow toward the nozzle body, soiling the nozzle body and marring the appearance of the fuel supply device.

[0007] The present invention has been made in consideration of the problems with the conventional fuel filler nozzles described above, and aims to provide a fuel filler nozzle that has a simple structure that prevents deterioration of the sealing performance of the oil receiving section and effectively prevents fuel oil from entering the nozzle body from the discharge pipe.

[0008] In order to achieve the above object, the present invention provides a refueling nozzle comprising a discharge pipe inserted into a fuel tank of a vehicle, and a nozzle body to which the discharge pipe is connected and which has a flow path through which fuel oil flows into the discharge pipe, the nozzle being hung on a nozzle hanger arranged on a refueling machine body with the discharge outlet of the discharge pipe facing upward, the nozzle being characterized in that a discharge pipe attachment section for attaching the discharge pipe to the nozzle body or an oil receiving section is provided on the nozzle body, the oil receiving section being provided with a storage section for storing fuel oil between the oil receiving section and the discharge pipe attachment section, and a gutter section in the oil receiving section for guiding the fuel oil stored in the storage section so that it drips in a direction other than the direction of the nozzle body.

[0009] According to the present invention, fuel oil that overflows from the reservoir drips through the gutter in a direction other than the direction of the nozzle body, so that operation of the fueling nozzle is not hindered.

[0010] In the fuel nozzle, the gutter section guides the fuel oil stored in the storage section so that it drips toward the fuel dispenser body, so that the fuel oil does not drip onto the nozzle body, grip section, or nozzle lever, and does not soil the hands or clothes of workers or customers.

[0011] Furthermore, by fastening the oil receiving portion to the nozzle body together, the gutter portion can be positioned relative to the nozzle body.

[0012] The oil receiving portion may be attached to the discharge pipe attachment portion, which makes it easier to attach the oil receiving portion.

[0013] Furthermore, by configuring the end of the oil receiving portion opposite the side where the gutter portion is located to abut against the surface of the base portion of the discharge pipe, the oil receiving portion can be positioned in the front-to-rear direction and can be arranged in a predetermined position.

[0014] A recess is formed in part of the end of the oil receiving portion opposite the side where the gutter portion is located, and this recess engages with a protrusion formed on the discharge pipe mounting portion, thereby allowing the oil receiving portion to be positioned circumferentially relative to the discharge pipe mounting portion.

[0015] As described above, according to the present invention, it is possible to provide a fuel supply nozzle that has a simple structure that prevents deterioration of the sealing performance of the oil receiving portion and effectively prevents fuel oil from entering the nozzle body from the discharge pipe.

[0017] Next, embodiments of the present invention will be described in detail with reference to the drawings.

[0018] FIG. 1 shows a first embodiment of a fuel filling nozzle according to the present invention. This fuel filling nozzle 1 comprises a discharge pipe 2 to be inserted into a fuel tank of a vehicle, a nozzle body 3 having a flow path through which fuel oil flows to the discharge pipe 2, a nozzle lever 4 provided on a grip portion 3 a of the nozzle body 3, a lever guard 5 that protects the nozzle lever 4, and an oil receiving portion 6.

[0019] The oil receiving part 6 is made of rubber such as vinyl chloride or NBR, and as shown in Figure 2, is provided on the discharge pipe mounting part 2a that mounts the discharge pipe 2 to the nozzle main body 3. As shown in Figure 3, it is formed into a cylindrical shape overall, and is provided with a reservoir 6a that stores fuel oil between the oil receiving part 6 and the discharge pipe mounting part 2a, and a gutter 6b that guides the fuel oil F stored in the reservoir 6a so that it drips toward the fuel tanker main body 10. A notch 6c is formed in the gutter 6b of the oil receiving part 6, and the fuel oil F stored in the reservoir 6a drips from this notch 6c in a predetermined direction.

[0020] The lower end 6d of the oil receiving portion 6 abuts against the surface of the base portion 2c of the discharge pipe 2, thereby positioning the oil receiving portion 6 in the front-to-rear direction and enabling the oil receiving portion 6 to be disposed in a predetermined position. As shown in Figure 2(a), a recess 6e is formed in the lower end 6d of the oil receiving portion 6, and the recess 6e engages with a protrusion 2f formed on the discharge pipe mounting portion 2a (Figure 2(a) shows the state before engagement, and Figure 2(b) shows the state after engagement), thereby positioning the oil receiving portion 6 in the circumferential direction relative to the discharge pipe mounting portion 2a and orienting the notch 6c toward the fuel tanker body 10.

[0021] After the oil receiving portion 6 is attached so that it abuts against the surface of the base portion 2c of the discharge pipe 2, it is tightened with a hose band 9, whereby the oil receiving portion 6 is firmly fixed to the discharge pipe mounting portion 2a, and the space between the oil receiving portion 6 and the discharge pipe mounting portion 2a is sealed, preventing fuel oil F from entering the nozzle body 3.

[0022] As described above, the oil receiving portion 6 can be attached to the discharge pipe attachment portion 2a, which makes attachment easy.

[0023] As shown in Figure 1, after refueling is completed, the refueling nozzle 1 having the above configuration is hung on the nozzle hanger 8 arranged on the refueling machine main body 10 with the discharge outlet 2b of the discharge pipe 2 facing upward. As the refueling nozzle 1 is used, fuel oil F gradually accumulates in the reservoir 6a of the oil receiver 6, and when the fuel oil F overflows from the reservoir 6a, the overflowing fuel oil F drips from the notch 6c toward the refueling machine main body 10. This effectively prevents fuel oil F from seeping into the nozzle main body 3 from the discharge pipe 2.

[0024] Next, a second embodiment of a fuel filler nozzle according to the present invention will be described with reference to Figures 4 to 6. In the fuel filler nozzle 11 according to the second embodiment, the same components as those in the fuel filler nozzle 1 according to the first embodiment are designated by the same reference numerals and will not be described again.

[0025] The fuel nozzle 11 includes an oil receiving portion 16, which is made of resin or a metal such as stainless steel or aluminum, and is fastened to the nozzle body 3 with bolts 18 and 19, as shown in Fig. 5. As shown in Fig. 6, the oil receiving portion 16 is formed in an overall cylindrical shape and includes a reservoir 16a for storing fuel oil between the oil receiving portion 16 and the discharge pipe mounting portion 2a, and a gutter 16b for directing the fuel oil F stored in the reservoir 16a so that it drips toward the fuel dispenser body 10. The gutter 16b is formed with a recess 16c and a beak-shaped protrusion 16d, and the fuel oil F stored in the reservoir 16a drips from the protrusion 16d in a predetermined direction.

[0026] Bolt holes 16e and 16f are drilled in the lower part of the oil receiving part 16, and bolts 18 and 19 are inserted through these holes to fasten the entire oil receiving part 16 to the nozzle body 3, positioning the oil receiving part 16 in the front-rear and circumferential directions, with the protruding part 16d facing the fuel supply machine body 10. As shown in Figure 4(c), an O-ring 17 is disposed at the base part 2c of the discharge pipe 2 to prevent fuel oil F from entering the nozzle body 3.

[0027] As shown in Figure 4, after refueling is completed, the refueling nozzle 11 having the above configuration is hung on the nozzle hanger 8 arranged on the refueling machine main body 10 with the discharge outlet 2b of the discharge pipe 2 facing upward. As the refueling nozzle 11 is used, fuel oil F gradually accumulates in the reservoir 16a of the oil receiver 16, and when the fuel oil F overflows from the reservoir 16a, the overflowing fuel oil F passes through the recess 16c and drips from the protrusion 16d toward the refueling machine main body 10. This effectively prevents fuel oil F from seeping into the nozzle main body 3 from the discharge pipe 2.

[0028] In the above-described fuel filling nozzles 1, 11, the provision of recesses 6c, 16c and protrusions 16d in the gutter sections 6b, 16b of the oil receiving sections 6, 16 causes the fuel oil F to flow in a fixed direction, so a tray (not shown) may be provided in front of the front panel of the fuel filling machine main body 10 and below the nozzle hanger 8 to collect the dripping fuel oil F. In addition, the dripping fuel oil F can be guided into the housing main body of the fuel filling machine main body 10 to prevent the area around the fuel filling nozzles 1, 11 from becoming dirty.

[0029] Next, a third embodiment of a fuel filler nozzle according to the present invention will be described with reference to Figures 7 and 8. In the fuel filler nozzle 21 according to the third embodiment, the same components as those in the fuel filler nozzles 1 and 11 according to the first and second embodiments are designated by the same reference numerals, and duplicated descriptions will be omitted.

[0030] The fuel nozzle 21 is provided with an oil receiving portion 26, which is made of resin or a metal such as stainless steel or aluminum, and is fastened to the nozzle body 3 with bolts 18 or the like, as shown in Figure 7(b). As shown in Figure 8, the oil receiving portion 26 is formed in an overall cylindrical shape, and is provided with a gutter portion 26b that guides fuel oil F (see Figure 7(b)) so that it drips toward the fuel dispenser body 10. A beak-shaped protrusion 26d is formed in the gutter portion 26b, and the fuel oil F drips in a predetermined direction from this protrusion 26d.

[0031] Bolt holes 26e, 26f are drilled in the lower part of the oil receiving part 26, and bolts 18 and the like are inserted into these holes to fasten the entire oil receiving part 26 to the nozzle body 3, positioning the oil receiving part 26 in the front-rear and circumferential directions, with the protruding part 26d facing the fuel tanker body 10. As shown in Figure 7(b), an O-ring 27 is disposed at the tip of the oil receiving part 26 to prevent fuel oil F from entering the nozzle body 3.

[0032] 4 and 6, in the second embodiment, fuel oil F dripping from the discharge pipe 2 is stored in a storage section 16a (a gap between the inner diameter of the oil receiver 16 and the outer diameter of the discharge pipe 2, using an O-ring 17 near the joint between the discharge pipe 2 and the oil receiver 16). With this configuration, there is a risk that the fuel oil F in the storage section 16a will splash onto the vehicle and adhere to it when the discharge pipe 2 is inserted into the fuel filler opening of the vehicle the next time it is refueled.

[0033] Therefore, in this embodiment, an O-ring 27 is attached to the tip of the oil receiving portion 26, eliminating the storage portion 16a, so that when the fueling nozzle 21 is returned to the nozzle hanger 8 with the discharge port 2b facing upward after refueling is completed, the fuel oil F that drips from the discharge pipe 2 drips directly downward into the fueling machine body 10 from the beak-shaped discharge portion 26d of the oil receiving portion 26. This prevents the fuel oil F from entering the nozzle body from the discharge pipe 2 and also prevents the fuel oil F from splashing the next time the fuel is refueled.

[0034] The illustrated embodiments are merely examples and are not intended to limit the technical scope of the present invention.
