An apparatus for testing a fuel cap includes a gas manifold, a fuel cap connector, a base, and a removable cover. The gas manifold is configured to provide a bidirectional flow path through the fuel cap. The fuel cap connector is integrated with or coupled to the gas manifold, and the fuel cap connector is configured to connect the fuel cap to the gas manifold. The base is configured to support the gas manifold and provide at least a first gas input to the gas manifold and through the fuel cap via the bidirectional flow path. The removable cover is configured to be removably connected to the gas manifold and provide at least a second gas input to the gas manifold and through the fuel cap via the bidirectional flow path.

A fuel cap for a vehicle has a locking structure configured to generate a sound interval, including a head portion having a handle formed at a first side and one or more striking portions installed at a second side, and a body portion integrally assembled with the head portion and having a plurality of sound generators installed at the body portion and disposed in a state of being struck by the one or more striking portions installed at the second side of the head portion according to a rotation of the head portion by a locking torque.

A filling head for an operating liquid tank, in particular of a motor vehicle, comprising a filling tube with an inlet end, which lies farther away from the tank, and an outlet end, which lies nearer to the tank, the filling tube for conducting operating liquid in a filling direction from the inlet end to the outlet end, a venting arrangement with an inflow end, which lies nearer to the tank and an outflow end which lies farther away from the tank, which end is provided for passing of gas in a counter-flow direction with respect to liquid flowing in the filling direction, in a venting direction extending from the inlet to the outflow end, the venting arrangement is provided, at least in the area of its outflow end, separate from the filling tube, the venting arrangement has a valve with a gas valve body, which is movable between a closed position, in which a gas flow in a valve passage is prevented, and a passage position, in which the gas may flow in the valve passage past the gas valve body, the valve having a liquid valve body, which is movable between a blocking position, in which a liquid flow in the valve passage is blocked, and an open position, in which the valve passage past the liquid valve body is open.

A link connecting a lid and a base member of a filler lid structure includes first and second link members. At an opening position, a distance between a distal end of the lid and the base member is larger than a distance between a proximal end of the lid and the base member. The first link member swings about a first support portion in a direction in which a second support portion is moved away from the base member, when the lid shifts from a closing position to the opening position. A distance between a base support point at which the base member or the first link member supports a third support portion at the closing position and an end support point at which the lid supports a fourth support portion at the closing position changes when the lid shifts from the closing position to the opening position.

The invention relates to a filler neck (1) for an auxiliary liquid reservoir for a motor vehicle, in particular for a urea reservoir, having a neck housing (9), which defines a mouth hole stub (10) for a filler nozzle (7) and a filling channel (11) leading into the reservoir, wherein a receiving structure for a filler nozzle (7) is provided within the neck housing (9). At least one venting path, which is of enlarged cross section, at least in a section or sections, and of chamber-like or labyrinth-like design, is formed within the neck housing (9), allowing a venting flow parallel and counter to the refilling volume to flow through the neck housing (9) during refilling.

A fuel tank cap locking device includes: a cap configured to open and close a fuel filler port; an operation unit; an engagement unit movable in conjunction with the operation unit; and a lock unit configured to lock movement of the engagement unit from the engagement position to the allowable position. The lock unit includes a lock member that is movable between an interference position where the lock member interferes with an interfered portion formed at a predetermined position of the engagement unit and locks, and a non-interference position where the lock member does not interfere with the interfered portion and the lock is released when the engagement unit moves from the engagement position to the allowable position by the swing operation of the operation unit.

Disclosed is a fuel supply structure for a filler pipe including the hollow circular cylindrical part having the fuel filler port and the connection opening, the first flap mechanism which is disposed on a side of the fuel filler port of the hollow circular cylindrical part and opens the fuel filler port in response to press by a nozzle, the drain through hole for communication between the inside and the outside of the hollow circular cylindrical part, and the drain hole shutting valve for open and shutting the drain through hole. The drain hole shutting valve is provided with the opening/shutter mechanism including the valve member for shutting the drain through hole in response to an opening operation of the first shutter member.
