A lock of a motor vehicle lid has a box and a cover, a locking pin provided with a head that protrudes from the cover to engage with a housing of a lid in order to close the lid. The locking pin is internally empty and has a through axial channel. A central pin is mounted with the possibility of sliding in an axial direction in the through axial channel of the locking pin. A spring is disposed between the box and the central pin to push the central pin and the locking pin to the extracted position. Detection is provided in the box to detect when the central pin is in retracted position or in extracted position.

A fuel tank structure for a saddle-ride vehicle for discharging fuel leaking out from a filler neck between a cover member and a fuel tank. The fuel tank structure includes a filler neck having a collar portion projecting upwardly from an upper surface of a fuel tank with a tank cap to seal the filler neck. A tank cover includes a cover opening portion into which the collar portion is inserted for covering the circumference of the filler neck. The tank cap has an extending wall portion for surrounding the outside of the collar portion and extending to a position below the cover opening portion so that fuel leaking from the filler neck is discharged through a clearance between the fuel tank and the tank cover.

A fuel-mixing prevention filler neck device is provided. The fuel-mixing prevention filler neck device includes a fuel dispensing gun insertion unit that receives a fuel dispensing thereinto and a coupling unit that provides fluid communication with a bottom of the fuel dispensing gun insertion unit. The coupling unit is disposed on an exterior circumferential surface thereof with coupling protrusions for fastening with a plurality of slots formed in a filler pipe. Further, a first side of a lower portion of the coupling unit is open to form a coupling region. A misfueling prevention unit slidably moves to the coupling region to be coupled to the coupling unit. Additionally, the misfueling prevention unit is closed when a gasoline fuel dispensing gun is inserted and being opened when a diesel fuel dispensing gun is inserted.

A fuel supply system provided comprises: a resin filler neck configured to have an opening which a fuel nozzle is inserted through and have a multi-layered structure of a conductive layer of electrical conductivity and a non-conductive layer of non-electrical conductivity; a resin fuel pipe connected with the filler neck and configured to have a multi-layered structure including a conductive outer layer of electrical conductivity provided as an outermost layer; and a cap member of electrical conductivity configured to open or close the opening of the filler neck. The filler neck includes a cap member contact part of electrical conductivity arranged to come into contact with the cap member and a conductive outer layer contact part of electrical conductivity arranged to come into contact with the conductive outer layer of the fuel pipe, so as to form a conductive path from the cap member to the conductive outer layer of the fuel pipe.

The present disclosure pertains to a sealing unit such a fuel tank cap for a tank unit of a motor vehicle. The sealing unit includes a cover element that can be arranged on or at least partially in an opening of a tank component of the motor vehicle such that it seals the opening of the tank component in an at least fluid-tight fashion. An actuator is arranged on an outer side of the cover element that faces away from the opening. In a non-actuated, normal position rests, flat against the outer side of the cover element. The actuator can be transferred into a gripping position, in which it at least partially extends oblique or transverse to the outer side of the cover element.

Disclosed is a fuel injection hole cap for preventing explosion due to static electricity which is characterized in that it is possible to prevent any fire due to an explosion of fuel evaporation gas in such a way to instantly discharge static electricity the instant that a user touches with a hand injection hole cap before the fuel injection hole cap is opened, without carrying any device with him which is configured to prevent the occurrence of static electricity. For this, at the fuel injection hole cap of a vehicle, there is provided a static electricity discharger which is configured to discharge static electricity and flash by the current of the discharging, thus informing the use of the discharging.

A fuel filler structure includes a base member, a shutter member, a seal part, and an opening part. The base member includes a fuel filler port and a fuel filler port outer circumferential part which is provided outward further than the fuel filler port. In the shutter member, an opening-closing valve is supported movable to a closed position and an open position. The seal part is arranged between the fuel filler port outer circumferential part and the opening-closing valve when the opening-closing valve is located at the closed position. The opening part connects together an outer surface and an inner surface of the fuel filler port outer circumferential part, and a second opening end of the opening part is arranged at a position that overlaps the opening-closing valve when the opening-closing valve is located at the closed position.

A filler tube, which is capable of satisfying required functions suitably in compliance with the bellows and non-bellows cylindrical base while securing weld strength and fuel-permeation resistance property in the weld face, is provided. A filler tube includes a non-bellows cylindrical base with a total thickness of from 2 to 4 mm, a bellows with a total thickness of from 0.5 to 3 mm, and a flange having a total thickness of from 3.5 to 5 mm, and including an end face to be welded to a fuel tank. The non-bellows cylindrical base, the bellows, and the flange include inner layers formed so as to have a thickness accounting for from 40 to 60% of the total thicknesses, and formed of high-density polyethylene (or HDPE) serving as the major constituent, intermediate layers exhibiting fuel-permeation resistance property, and outer layers protecting the intermediate layers.

A pressure tight plug for sealing a coupler of a dry disconnect valve includes a housing, a main flow valve, and at least one urging member being rotatable with respect to the housing of the coupler. The pressure tight plug includes a body, a locking ring, a pressure relief lock valve, and a pressure relief channel. The body includes an internal region for sealing adjacent the main flow valve of the coupler member, and a flanged perimeter for securing the plug to the coupler. The locking ring is receivable on, and rotatable with respect to, the body for engaging with the at least one urging member of the coupler. The pressure relief lock valve is fixed with respect to the body. The pressure relief channel extends from the internal region of the body to atmosphere, via said pressure relief lock valve. The pressure relief lock valve is arranged such that in a valve closed position the pressure relief lock valve is engaged with the locking ring, therein restricting movement of the locking ring and therein fixing the plug to the coupler.
