Problems solved by technology

[0010] That is, when the flapper valve of the capless fuel supply system is pressed by the front end of the emergency nozzle to open the valve in a fully open state, the sealed fuel passage in the filling pipe suddenly changes from a pressurized state to an open state to the atmosphere, so the fuel may be released. The vapor is blown back to the outside

Embodiment Construction

[0042] Next, embodiments of the present invention will be described in detail with reference to the drawings as appropriate. figure 1 It is a schematic block diagram of the refueling structure including the capless refueling mechanism into which the refueling auxiliary tool according to the embodiment of the present invention is inserted, viewed from the rear of the vehicle, figure 2 yes figure 1 An enlarged cross-sectional view of the capless refueling mechanism shown.

[0043] Such as figure 1 As shown, the refueling structure 10 is, for example, disposed on a rear fender 12 located at the rear of the vehicle body. An adapter 16 , which is positioned above the rear tire 14 and has an opening, is mounted on the inner side in the vehicle width direction of the rear fender 12 . On the side of the rear fender 12 facing the adapter 16 , a cover (not shown) is attached through a hinge so as to be openable and closable.

[0044] and, if figure 2 As shown, the refueling struc...

Abstract

The present invention provides a refueling aid capable of suppressing blowback of fuel vapor to the outside in a capless refueling mechanism. The capless refueling mechanism (20) includes a filler-side cut-off valve (28) arranged on a filler-port (24) side, and a fuel-tank-side cut-off valve (30) arranged closer to the fuel tank than the filler-side cut-off valve (28). The refueling auxiliary tool (50) has a guide pipe part (52) and a funnel part (54), and the fuel tank side stop valve (28) and the fuel tank side stop valve (30) are pressed by the front end (52a) of the guide pipe part (52). ), so that the spool (44) is separated from the seating portion (42), and refueling can be performed by inserting the nozzle (64) into the funnel portion (54). An enlarged diameter portion (58) that restricts the valve opening of the spool (44) of the side stop valve (30).

Description

technical field [0001] The present invention relates to a fueling auxiliary tool used in a vehicle having a capless fueling mechanism at the front end of a fueling pipe. Background technique [0002] For example, Patent Document 1 discloses a capless refueling system that is arranged at the tip of a filler pipe and is snap-fitted by a valve assembly. It should be noted that "capless" means that there is no fuel cap conventionally provided at the fuel filler. [0003] This valve assembly includes a lower main body and an upper cover. A flapper valve biased by a spring into a seated state is disposed on the lower main body portion. Another flapper valve biased by a spring into a seated state is disposed on the upper cover. [0004] prior art literature [0005] patent documents [0006] Patent Document 1: Japanese PCT Publication No. 2013-509328 [0007] Summary of the invention [0008] The problem to be solved by the invention [0009] However, there is a case where ...
