A fuel tank includes a tank panel in which a storage space of a fuel is formed, a tank inlet fixed to the tank panel, and a tank cap that allows the tank inlet to be opened and closed. The tank inlet includes a bottomed cylindrical inlet plate to which the tank cap is attached, an inlet pipe that protrudes from a bottom wall of the inlet plate into the storage space, and a separator configured to separate the fuel entering from the storage space into a liquid component and a gas component. The separator is supported by the bottom wall of the inlet plate in the storage space, and the separator is disposed on an outer side of the inlet pipe and on an inner side relative to an outer edge of the inlet plate in a bottom view of the tank inlet.

The lid device for vehicle includes a link member supporting a lid to open and close; and a basing member moving the lid from a fully-closed position to a first reference position which is a partly-open position, and moving the lid from a second reference position which is further in the open direction than the first reference position to a fully-open position. The link member includes first and second link members pivotally supported at one end on the rear side of the lid, and pivotally supported at the other end within the housing. The biasing member has a pop-up contact part for switching the lid from the closed position to the first reference position, and a deadlock contact part inner surface for switching between biasing toward the first reference position and biasing toward the fully opening position with the second reference position in between.

A closure cap for an operating medium tank is provided with a closure device projecting into a fill socket of the operating medium tank. The closure device has a first cap element, a second cap element, and a sealing ring arranged between the first and second cap elements. A lifting assembly axially moves by an axial travel the first and second cap elements relative to each other for opening and closing the fill socket. The lifting assembly has a pressure member acting axially on one of the first and second cap elements. A grip member is provided that is rotatable about a hub and actuates the lifting assembly. A cover disk covering at least partially the fill socket relative to an exterior is connected fixedly to the pressure member of the lifting assembly. The cover disk rotates, together with the pressure member, about the hub.

A lockable assembly for a fuel filler pipe including a cap supported upon a unit mounted to the fuel filler pipe. The clip has at least one locking tab which is actuated by a key insertable portion incorporated into the cap and in order to lock or unlock the cap for removal from the outside part of the unit attached to the filler pipe. The key insertable portion can further include a rotatable component. The at least one locking tab further includes a pair of locking tabs which are radially displaced via the rotatable component so that the tabs displace in opposite directions. Other features include a sliding limiter component associated with each of the oppositely directed locking tabs.

A lock device of a fuel tank cap includes: a cap configured to open and close a fuel filler port; an operating unit; a fastening unit movable in conjunction with an operation of the operating unit; a lock unit configured to lock movement of the fastening unit from a fastening position to a allowing position; and a detection switch configured to detect start of the movement of the fastening unit accompanying the operation of the operating unit. The fastening unit includes: a first fastening unit of which the start of movement can be detected by the detection switch; and a second fastening unit which enables locking by the lock unit and which is integrally moved with the first fastening unit after the first fastening unit is moved by a predetermined dimension so that the second fastening unit can be moved from the fastening position to the allowing position.

Battery powered, keyless locking container cap configured securing a bayonet filler neck or threaded filler neck remaining unlocked after attachment. A timer circuit powers off placing the invention into an energy saving, mode; a compression spring forces a coupler into engagement. While engaged, the cap can be removed and replaced. Cap rotation by an unauthorized user, locks the cap. A backup, rotary pin coded lock is in the interior inaccessible. Cap rotation enters a pin code to unlock or lock the cap. The invention supplied is with a transmitter configured as a key fob or a cigarette lighter power plug. the transmitter signals the cap not to lock thereby providing removal. rotational Comprising rotary frictional slippage prevents unauthorized removal by limiting both speed and the rotational force to a level insufficient to override the attachment torque.

Methods and systems are provided for a refueling cap locking mechanism. In one example, a method includes unlocking the refueling cap in response to an engine start. The unlocking occurs without a vehicle operator input outside of a request to start the engine.

Methods and systems are provided for increase a rate at which a saddle fuel tank is depressurized responsive to a request for refueling. In one example, a method may include, responsive to the request for refueling, depressurizing a primary side of the saddle fuel tank to a secondary side of the saddle fuel tank, and commanding open a refueling lock coupled to the primary side to allow fuel to be delivered to the primary side when pressure in the primary side drops below a threshold pressure. In this way, the secondary fuel tank may be maintained at atmospheric pressure prior to the request for refueling, which may increase the rate of depressurization of the saddle fuel tank responsive to the request.

This invention provides a kind of fuel filler cap actuator and automotive vehicle, comprising screw shaft, rotor, housing, first reset spring, lock block and lock block driving device; Under the action of the lock block driving device, the lock block can be rotated between the locking angle and the unlocking angle; the lock block driving device adopts an electromagnetic drive method to drive the lock block. This avoids the use of a motor drive, and achieves locking/unlocking of the fuel filler cap through the mutual interaction of the first and second magnet, which significantly reduce operational costs and increase life expectancy.
