Description

BACKGROUND1. Field of the Invention

[0001] The present invention relates to a fueling nozzle used for dispensing fuel into automobile fuel tanks and the like at fuel stations.2. Description of the Related Art

[0002] Conventionally, a fueling nozzle attached to the end of a fuel hose of a fueling device at fuel stations for dispensing fuel oil to automobiles is hung on a nozzle hook with a discharge pipe facing upward after fueling is completed. This sometimes causes fuel adhering to the discharge pipe to drip down, thereby soil a nozzle body. In the case of volatile fuels such as gasoline, this is not a problem as the fuel evaporates before reaching the nozzle body. However, with fuels that are difficult to evaporate, such as diesel oil or kerosene, the fuel adhering to the discharge pipe drips down and soils the nozzle body, which in turn soils hands or clothes of the next person who uses it for fueling, leaving room for improvement.

[0003] Therefore, the applicant proposed in WO2018 / 158872A to provide an oil receiving part on the nozzle body to receive fuel oil dripping from the discharge pipe, thereby preventing the nozzle body from becoming soiled.

[0004] The content of International Publication WO2018 / 158872 is incorporated herein by reference in its entirety.BRIEF SUMMARY

[0005] While the above proposal is effective, a sealing part of the oil receiving part exists at an outer diameter part of an end of the discharge pipe, and when attaching the oil receiving part to a nozzle body side of the discharge pipe, it is necessary to climb over an anchor spring configured on the discharge pipe. During this process, there is a risk that the sealing part of the oil receiving part may be damaged, resulting in poor sealing performance and causing fuel oil leakage.

[0006] Additionally, depending on the amount of fuel oil adhering to the discharge pipe, there was a risk that the fuel oil might overflow from the oil receiving part and flow to the nozzle body side, soiling the nozzle body and detracting from the appearance of the fueling device.

[0007] The present invention has been made in view of the above-mentioned problems in conventional fueling nozzles, and its object is to provide a fueling nozzle that can prevent deterioration of the sealing performance of the oil receiving part with a simple structure and effectively prevent fuel oil from entering the nozzle body from the discharge pipe.[Means for solving the problem]

[0008] To achieve the above object, the present invention provides a fueling nozzle including a discharge pipe inserted into a vehicle's fuel tank and a nozzle body to which the discharge pipe is connected and which has a flow path through which fuel oil flows to the discharge pipe, wherein the fueling nozzle is hung on a nozzle hook provided on a fueling device body with a discharge opening of the discharge pipe facing upward, characterized in that an oil receiving part is provided on a discharge pipe attachment part for attaching the discharge pipe to the nozzle body or on the nozzle body, a reservoir part is provided between the oil receiving part and the discharge pipe attachment part for storing fuel oil, and a gutter is provided on the oil receiving part for guiding the fuel oil stored in the reservoir part to drip in a direction other than toward the nozzle body.

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

[0010] In the fueling nozzle, the gutter guides the fuel oil stored in the reservoir part to drip in the direction of the fueling device body, so that the fuel oil does not drip onto the nozzle body, grip part, or nozzle lever, preventing soiling of the hands or clothes of workers or customers.

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

[0012] The oil receiving part may be attached to the discharge pipe attachment part, which makes attaching the oil receiving part easier.

[0013] Additionally, by configuring an end part of the oil receiving part on a side opposite to a side where the gutter exists to abut against a surface of a root part of the discharge pipe, the oil receiving part can be positioned in a front-back direction and installed in a predetermined position.

[0014] A part of the end of the oil receiving part on the side opposite to the side where the gutter exists has a recess, and the recess engages with a protrusion formed on the discharge pipe attachment part, thereby enabling the positioning of the oil receiving part in its circumferential direction with respect to the discharge pipe attachment part.EFFECTS OF THE INVENTION

MODE FOR CARRYING OUT THE INVENTION

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

[0018] Figure 1 shows a fueling nozzle according to the first embodiment of the present invention. This fueling nozzle 1 includes a discharge pipe 2 inserted into a vehicle's fuel tank, 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 part 3a of the nozzle body 3, a lever guard 5 protecting the nozzle lever 4, and an oil receiving part 6.

[0019] The oil receiving part 6 is made of polyvinyl chloride or rubber such as NBR, and as shown clearly in Fig. 2, it is provided on a discharge pipe attachment part 2a for attaching the discharge pipe 2 to the nozzle body 3, and as shown in Fig. 3, it is formed in an overall cylindrical shape and has a reservoir part 6a that stores fuel oil between the oil receiving part 6 and the discharge pipe attachment part 2a, and has a gutter 6b that guides a fuel oil F stored in the reservoir part 6a to drip in a direction of the fueling device body 10. The gutter 6b of the oil receiving part 6 has a cutout 6c, and the fuel oil F stored in the reservoir part 6a drips in a predetermined direction from this cutout 6c.

[0020] A lower end part 6d of the oil receiving part 6 abuts against a surface of a root part 2c of the discharge pipe 2, thereby positioning the oil receiving part 6 in a front-back direction and enabling the oil receiving part 6 to be installed in a predetermined position. Also, as clearly shown in Fig. 2(a), the lower end part 6d of the oil receiving part 6 has a recess 6e, and the recess 6e engages with a protrusion 2f formed on the discharge pipe attachment part 2a (Fig. 2(a) shows a state before engagement, and Fig. 2(b) shows a state after engagement), thereby positioning the oil receiving part 6 in its circumferential direction with respect to the discharge pipe attachment part 2a, and the cutout 6c is directed toward the fueling device body 10.

[0021] After mounting the oil receiving part 6 so that it abuts against a surface of the root part 2c of the discharge pipe 2, it is firmly fixed to the discharge pipe attachment part 2a by tightening it with a hose band 9, thereby sealing between the oil receiving part 6 and the discharge pipe attachment part 2a and preventing the fuel oil F from entering the nozzle body 3.

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

[0023] As shown in Fig. 1, the fueling nozzle 1 having the above configuration is hung on a nozzle hook 8 provided on the fueling device body 10 with a discharge opening 2b of the discharge pipe 2 facing upward after fueling is completed. With the use of the fueling nozzle 1, the fuel oil F gradually accumulates in the reservoir part 6a of the oil receiving part 6, and when the fuel oil F overflows from the reservoir part 6a, the overflowing fuel oil F drips from the cutout 6c in the direction of the fueling device body 10. It is therefore possible to effectively prevent the fuel oil F from entering the nozzle body 3 from the discharge pipe 2.

[0024] Next, a fueling nozzle according to the second embodiment of the present invention will be described with reference to Figs. 4 to 6. In the fueling nozzle 11 according to the second embodiment, the same components as those in the fueling nozzle 1 according to the first embodiment are denoted by the same reference numerals, and redundant explanation will be omitted.

[0025] The fueling nozzle 11 includes an oil receiving part 16, which is made of resin or metal such as stainless steel or aluminum, and as clearly shown in Fig. 5, is fastened together to the nozzle body 3 with bolts 18 and 19. As shown in Fig. 6, the oil receiving part 16 is formed in an overall cylindrical shape and has a reservoir part 16a that stores fuel oil between the oil receiving part 16 and the discharge pipe attachment part 2a, and a gutter 16b that guides the fuel oil F stored in the reservoir part 16a to drip in the direction of the fueling device body 10. The gutter 16b has a recess 16c and a beak-shaped projecting part 16d, and the fuel oil F stored in the reservoir part 16a drips in a predetermined direction from this projecting part 16d.

[0026] A lower part of the oil receiving part 16 has bolt holes 16e and 16f, through which the bolts 18 and 19 are inserted, and the entire oil receiving part 16 is fastened together to the nozzle body 3. The oil receiving part 16 is positioned in its front-back and circumferential directions, and the projecting part 16d is directed toward the fueling device body 10. As shown in Fig. 4(c), an O-ring 17 is provided on the root part 2c of the discharge pipe 2, thereby preventing the fuel oil F from entering the nozzle body 3.

[0027] The fueling nozzle 11 with the above configuration is, as shown in Fig. 4, hung on the nozzle hook 8 provided on the fueling device body 10 with the discharge opening 2b of the discharge pipe 2 facing upward after fueling is completed. With the use of the fueling nozzle 1, the fuel oil F gradually accumulates in the reservoir part 16a of the oil receiving part 16, and when the fuel oil F overflows from the reservoir part 16a, the overflowing fuel oil F drips from the projecting part 16d through the recess 16c in the direction of the fueling device body 10, thereby, it is possible to effectively prevent the fuel oil F from entering the nozzle body 3 from the discharge pipe 2.

[0028] In the above fueling nozzles 1 and 11, by providing the cutout 6c and the recess 16c and projecting part 16d in the gutters 6b and 16b of the oil receiving parts 6 and 16, the fuel oil F flows in a constant direction, therefore, a receiving tray (not shown) may be provided at the front panel front face of the fueling device body 10 and below the nozzle hook 8 to collect the dripping the fuel oil F. It is also possible to guide the dripping fuel oil F into the housing body of the fueling device body 10 to prevent the area around the fueling nozzles 1 and 11 from becoming soiled.

[0029] Next, a fueling nozzle according to the third embodiment of the present invention will be described with reference to Figs. 7 and 8. In the fueling nozzle 21 according to the third embodiment, the same components as those in the fueling nozzles 1 and 11 according to the first and second embodiments are denoted by the same reference numerals, and redundant explanation will be omitted.

[0030] The fueling nozzle 21 includes an oil receiving part 26, which is made of resin or metal such as stainless steel or aluminum, and is, as shown in Fig. 7(b), fastened together to the nozzle body 3 with bolts 18 and the like. As shown in Fig. 8, the oil receiving part 26 is formed in an overall cylindrical shape and has a gutter 26b that guides the fuel oil F (refer to Fig. 7(b)) to drip in the direction of the fueling device body 10. The gutter 26b has a beak-shaped projecting part 26d, and the fuel oil F drips in a predetermined direction from this projecting part 26d.

[0031] A lower part of the oil receiving part 26 has bolt holes 26e and 26f, through which the bolts 18 and the like are inserted, and the entire oil receiving part 26 is fastened together to the nozzle body 3. The oil receiving part 26 is positioned in its front-back and circumferential directions, and the projecting part 26d is directed toward the fueling device body 10. As shown in Fig. 7(b), an O-ring 27 is provided at the tip part of the oil receiving part 26, thereby preventing the fuel oil F from entering the nozzle body 3.

[0032] In the second embodiment, as shown in Figs. 4 and 6, the fuel oil F dripping from the discharge pipe 2 is stored in the reservoir part 16a (the gap between the inner diameter of the oil receiving part 16 and the outer diameter of the discharge pipe 2 near the junction of the discharge pipe 2 and the oil receiving part 16 where the O-ring 17 is used). With this configuration, when inserting the discharge pipe 2 into the vehicle's fueling port during the next fueling, there is a concern that the fuel oil F in the reservoir part 16a might splash and adhere to the vehicle.

[0033] In this embodiment therefore, attaching the O-ring 27 to the tip part of the oil receiving part 26 allows the reservoir part 16a to be eliminated. When the fueling nozzle 21 is returned to the nozzle hook 8 with the discharge opening 2b facing upward after fueling is completed, the fuel oil F dripping from the discharge pipe 2 is directly dropped from the beak-shaped discharge part 26d of the oil receiving part 26 in the direction below the fueling device body 10. It is thereby possible to prevent the fuel oil F from entering the nozzle body from the discharge pipe 2 and also to prevent the fuel oil F from splashing during the next fueling.

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