A check valve for fuel tank comprises a joint that is fixed to a fuel tank, a passage forming part, and a valve member. The joint is connected to one end of the passage forming part, and an outlet is formed at the other end of the passage forming part. The valve member that opens and closes the outlet. The valve member comprises a valve element, a spring bearing part, a holding part continuous to at least one of the joint and the passage forming part, and a compression coil spring. The joint and the passage forming part are communicated to each other to form a fuel passage. At the end on the joint side of the passage forming part in the fuel passage, there is formed a diameter enlarged portion having an inner diameter gradually increasing from a fuel supply pipe side toward the outlet side.

A closure of a tank of a motor vehicle for closing a filler neck gas- and fluid-tight, having a closure fastened to a flap, the flap being fastened to a vehicle body of the motor vehicle such that it is movable into an open or closed position, the closure including a seal, which causes the closure to close against the filler neck. The tank closure should be easy for a user to handle and have a relatively simple design and be economical to manufacture. This is achieved in that the seal is electromechanically or pneumatically adjustable with the aid of an actuator.

A filler pipe includes a nozzle guide that is mounted on an inlet part of the filler pipe and holds a nozzle end part of a fueling gun. The nozzle guide includes a nozzle guide mounting part, which is mounted on the inlet part of the filler pipe, a nozzle guide holding part, which is positioned in a distal end of the nozzle guide, and holds the nozzle end part of the fueling gun, and a nozzle guide connecting part that connects the nozzle guide mounting part and the nozzle guide holding part with each other. The nozzle guide holding part has a plurality of projecting parts that are able to abut on an outer surface of a nozzle of the fueling gun. The nozzle guide is mounted on the inlet part of the filler pipe, at the nozzle guide mounting part, by swaging or spot welding.

Fluid containers to evacuate spilled fluid from the interior of an enclosure of the fluid container are disclosed. An example system includes an enclosure and a fluid container within the enclosure. The fluid container includes a fluid capture area at a top of the fluid container and a channel at a side of the fluid container. The fluid capture area directs the fluid to the channel, and the channel directs the fluid from an interior of the enclosure to an exterior of the enclosure.

A dual cap assembly having multiple passages, may include a pipe device having a plurality of separate passages; a first cap device detachably mounted at a position where the passages diverge in the pipe device to close a first passage; and a second cap device detachably mounted on the first cap device to close a second passage, wherein when the first cap device is separated from the pipe device, the first passage is opened, and when the second cap device is separated with the first cap device mounted on the pipe device, the second passage is opened while the first passage is closed.

A filler tube including a cylindrical body and flange is manufactured using a cylindrical workpiece. A material forms an outermost layer in the cylindrical body and flange of the cylindrical workpiece. Dividable molds move at a first speed upon adhering the cylindrical workpiece onto the site for forming the cylindrical body, thereby giving the cylindrical body a predetermined diametrical thickness; and then move at a second speed being slower than the first speed upon adhering the cylindrical workpiece onto the other site for forming the flange, thereby filling up the flange with the material and other materials for forming the flange over a diametrical range to be welded onto the fuel tank while making the diametrical thickness of the flange greater than that of the cylindrical body.

A fuel tank joint includes a tubular joint body and an entry restriction member. The joint body includes a support portion. The entry restriction member includes a body tube, a groove, a guide, and an engagement hook. The body tube has opposite open ends in the flow direction of fuel. The groove extends upstream from the downstream end of the body tube and is engaged with the support portion. The guide is formed in part of the body tube that includes the downstream end of the body tube and guides the groove to the support portion by contacting the support portion when the body tube is inserted into the joint body. The engagement hook is formed in a downstream end section of the body tube and engaged with the support portion, from a downstream side, in a state in which the groove is engaged with the support portion.

Systems are provided for refueling a fuel tank of a motor vehicle via a funnel including an insert. In one example, a system may include a funnel including an insert coupled to an inner circumference of the funnel, the insert including a plurality of projections positioned on an inner perimeter of the insert. The plurality of projections may include a first projection spanning a first axial length, a second projection spanning a second axial length, and a third projection spanning a third axial length.

Systems are provided for refueling a fuel tank of a motor vehicle via an insert for a filler pipe. In one example, a system may include an insert coupled to an inner circumference of the filler pipe, the insert including a plurality of projections positioned on an inner circumference of the insert. The plurality of projections may include a first projection spanning a first axial length, a second projection spanning a second axial length, and a third projection spanning a third axial length.

The invention concerns a delivery valve for the delivery of a fluid into a tank of a motor vehicle. According to the invention, the following is provided: a) the delivery valve has a first settable maximum volume flow, b) the delivery valve has a second settable maximum volume flow which is higher than the first settable maximum volume flow, c) a control device (24, 25), by means of which optionally the first or the second maximum volume flow can be set, d) a sensor device (20, 21), which is configured for interaction with a signal emitter (29) assigned to the tank of the motor vehicle and which activates the control device.
